With that, I will now turn the call over to David.

David DeStefano -- Chief Executive Officer

Thanks, Ankit. And thanks everyone for joining us on the call today. This year was remarkable in many ways and we continue to see the pace of change in the global business, technology, and regulatory environments, creating entirely new complexities and challenges in managing indirect tax. We believe our solutions will play an essential role as companies adapt their business models to support revenue growth through e-commerce platforms and marketplaces, drive resiliency in their global supply chain, and accelerate their move to the cloud.

We are very pleased with our fourth-quarter results as we close out the year. We continue to deliver strong fiscal year performance, which reflects the durability of our business, the strength of our customer and partner relationships, and our focus on driving sustainable profitable growth. We grew our total revenues by 16.5% for the full year to $374.7 million, and our adjusted EBITDA was up 15.5% year over year. We ended 2020 with annual recurring revenue per customer of over $78,000, up from $65,000 at the end of 2019.

Our performance was driven by the outstanding efforts of our Vertex team and partners around the world whose dedication and focus to our customers during these extraordinary times was on full display every day. We are pleased with the continued growth of our cloud business. For the full year, we grew our cloud revenues by 65% over 2019. And in Q4, we saw cloud revenue growth of 70%, compared to 54% in Q3.

We believe the pandemic may have accelerated the migration of customers' infrastructure and applications to the cloud, leading to increased adoption of our cloud solutions among our existing customers. Among our new logos, the vast majority of wins were cloud deals, especially in the middle market where tax complexity continues to increase. Going forward, as we estimate our cloud-based subscription revenues to exceed $100 million in revenue in 2021, we expect a more normalized growth rate of 35% plus for the year. Our fourth-quarter results also demonstrate that we continue to expand our revenues among large global multinational customers who while they continue to move many of their applications to the cloud still want to keep their order-to-cash applications behind the firewall, especially outside of the United States.

We believe our hybrid approach to serving both cloud and on-premise customer needs gives us a differentiated competitive advantage going forward as we pursue our addressable market globally. Now, I'd like to share some notable highlights from the fourth quarter. First, I'd like to start with our progress outside of the United States, which, as I have discussed, remains a key vector of growth for us going forward. We continue to see increased demand for our solutions in both Europe and Brazil where businesses face significant regulatory change and tax complexity.

We continue to invest in these regions to further capitalize on emerging growth opportunities. In Q4, we had a strategic win with the world's largest industrial manufacturing company. They look to us for an end-to-end solution for indirect tax management as part of their global SAP S/4HANA implementation. This win speaks to the differentiated value of our end-to-end capabilities, our strong relationships with global technology and accounting partners.

This customer is a good example of challenges many multinational organizations face when they move their infrastructure to the cloud. They want to leverage the cloud as much as possible. But for either specific business or IT reasons, they want to keep their order-to-cash process behind the firewall. Without an on-premise option, this customer would have continued using native functionality and internal workarounds.

In choosing Vertex, they can address their tax complexities today and have the confidence that we have an enterprise-scaled cloud solution when they are ready to migrate. This customer is also implementing our Chain Flow Accelerator for SAP, which we just released in the fourth quarter. As global enterprises continue to build resilient and dynamic supply chains, the cross-border shipping and moving of goods has significantly increased that compliance complexity and risk. We developed the Chain Flow Accelerator to help companies address this challenge.

This solution combines intelligent data visualization and data mapping within the SAP user interface to streamline the management of that complex scenarios associated with cross-border supply chain transactions without manual effort or modifications. This win is also notable because it leveraged our strong relationships with the tax technology advisory practices of the major accounting firms in both the U.S. and Europe to coordinate a truly global solution. These partners are a natural extension of our go-to-market motion and we've closed a number of large deals this quarter and throughout the fiscal year due to the strength of these relationships.

Another Q4 highlight is in Brazil where we've expanded our content database to serve the global breadth and depth required by our multinational customers doing business in one of the most complex tax environments in the world. Our investment in Systax in 2020 has enabled us to deliver new and expanded tax content for some of the biggest companies on the planet. In Q3, we helped one of these companies expand into new states in Brazil, requiring additional content for tax compliance there. In the fourth quarter, we helped them expand even further by supporting five additional states in the country.

I'm encouraged by the performance of our global teams and the significant opportunities we have ahead of us in those regions to support our global customers. In Q4, we also continued to broaden and deepen our global technology, channel, and partner ecosystem to strengthen our solutions and extend our go-to-market reach. We expanded our sales force integration supporting their lightning B2B e-commerce and order management applications. We also added a number of new Microsoft Gold partners in the quarter.

I'm excited about the investments we are making in these areas going forward as tax complexity continues to move into the front office, CRM, e-commerce, and procurement systems of today's global businesses. We also continue to build on our long-standing partnerships with SAP and Oracle. In particular, our cloud-to-cloud integrations and support for SAP S/4HANA, Oracle ERP cloud, and cloud infrastructure. In Q4, we worked with an SAP platinum partner who was implementing S/4HANA private cloud for a rapidly growing global healthcare company focused on innovative therapies.

They chose us because of our ability to provide strong SAP tax integration with enterprise-scale capabilities for U.S. and global tax. We continue to see increased demand through our Oracle Cloud infrastructure partnership with prospects and customers with several Q4 wins attributed to the benefits of our cloud-to-cloud solution. And we continue to build industry-specific content and partner relationships to support key verticals.

We expanded our partner ecosystem in the fourth quarter with a global leader in the leasing industry where managing tax continues to be highly complex, particularly with consumers and seller use tax. New logo acquisition remains strong in the fourth quarter among both enterprise and mid-market customers as growing tax complexity exceeds the capabilities of their native ERP or homegrown systems. This was the case with one of the world's largest quick-service restaurant companies who chose our solutions as part of their global point-of-sale rollout. We are also enabling an online delivery service provider to scale tax automation within their payment processing systems to support the rapid growth of their business in the pandemic.

And we signed a premier healthcare network in the U.S. because of the cloud-to-cloud integration with our solutions and their workday implementation. Average ARR among our new logos grew to nearly $59,000 in 2020 versus $53,000 in 2019, demonstrating the continued market opportunity -- tunity and value of our solutions in the enterprise and mid-market segments. Finally, our performance in the quarter was also driven by expanding our revenues from existing customers.

As our customers expand globally, accelerate their omnichannel strategies, and adopt best-of-breed front-office applications, we grow with them. In Q4, we expanded our revenues with a number of customers whose e-commerce growth has rapidly increased with the digital economy and in response to the pandemic, including a luxury fashion brand, an online food delivery service company, and one of America's largest sporting goods retailers. We continue to see our customers migrating to the cloud as their business needs change, including a large specialty service provider and one of our longtime telecom customers. We believe this reflects the strength of our brand and our customers' confidence in us to support their hybrid IT environments now and in the future as they evolve.

I'm so proud of what we accomplished in 2020 and our ability to effectively balance profitable growth with strategic investments in our technology and go-to-market scale. And I'm equally encouraged by what we've already accomplished in the first quarter of 2021. In January, we acquired Tellutax edge technology, which we believe represents the future of indirect tax technology. Its container architecture enables customers to deliver tax solutions seamlessly and what we call the point of need wherever transactions are conducted like mobile applications or connected device and do this with tremendous scale and simplified management.

We believe this acquisition can also enable us to extend our global capabilities into adjacent markets like next-generation payment and IoT platforms for a truly connected e-commerce experience. The teams are actively working to integrate this technology into our solution roadmaps. In February, we announced that Sal Visca had joined our team as chief technology officer. Sal is a recognized innovator and leader of global technology teams in e-commerce, business intelligence, and enterprise management software.

I'm so excited about the strategic value and creative thinking that he brings to Vertex. In closing, our Q4 and full-year results reflect the enduring strength of our business. The experience and brand we have built over the past 40 years remains an essential ingredient to our success. Despite the unique challenges of 2020, our business growth validates our strategies in the global market opportunity that exists for us in 2021 and beyond.

We are investing in the talent, technology, and partnerships needed to advance our vision to accelerate global commerce. And our team remains resilient and committed to our success and our customer. With that, I now turn it over to John to discuss our full-year results and outlook for 2021.

John Schwab -- Chief Financial Officer

Thank you, David, and thanks everyone for your time. Today, I'm going to discuss our fourth-quarter and full-year 2020 results and then we'll wrap up with comments on our capital structure and provide our first-quarter and full-year guidance. Total fourth-quarter revenues grew 15.7% year over year to reach $99.5 million. Subscription revenues grew 15.1% year over year to $83.9 million.

These revenues were benefited by annual transaction-based subscription adjustments, accounting for approximately $1.5 million of -- of additional revenue. Our services revenue increased 19% over the same period last year to $15.6 million due to a significant number of year-end implementation and upgrade projects. Total revenues for 2020 were $374.7 million, up 16.5% from 2019. Our annual recurring revenue, or ARR, grew to $316.4 million as of the end of 2020.

This represents a 13.6% year-over-year growth. As David mentioned, we continue to see strong growth in our cloud-based solutions among both existing customers and new customers. For the fourth quarter, cloud revenue grew 70%, which is up from 54% in the third quarter of 2020. We ended the full-year 2020 with our cloud revenues growing 65% over the full year of 2019.

Going forward, as our cloud base crosses $100 million in revenue in 2021, we are targeting a more normalized growth rate of approximately 35% for the year. We continue to lead cloud-first on all our new opportunities and believe that the shift to cloud presents a unique opportunity for the company to drive additional revenues and ARR growth. We believe our hybrid approach to serving both cloud and on-premise customer needs gives us a differentiated competitive advantage going forward as we pursue our addressable market globally. Our net revenue retention rate, or NRR, was 106% as of the end of 2020, demonstrating our customers' continued commitment to our software and solutions.

Our gross revenue retention remained at 91%, which is consistent throughout the 2020 quarters. Notably here, our GRR was impacted by approximately 300 basis points due to cloud migrations that occurred during 2020. In discussing the remainder of the income statement, please note that unless otherwise stated, the references to our expenses, operating results, and per-share results are on a non-GAAP basis and are reconciled to our GAAP results in the earnings press release that was issued today. On an overall basis, gross profit for the fourth quarter was $70.4 million, representing a 70.7% gross margin.

This compares with gross profit of $61.8 million and the 71.7% gross margin in the same period last year. The 100-basis-point change reflects our investment in cloud infrastructure, tax content, and customer success management areas. From a subscription software standpoint, our gross margin was 76.8% as compared to 78.5% in the prior year, driven by continued investment in our cloud infrastructure tax content and customer success management. Our gross margin in our services business increased to 38.4% from 34% in the prior year.

We continue to see demand for services from implementation of new software, as well as from existing customer projects but anticipate that the margins will moderate. For the full year, subscription software gross margin was 77.9%, compared to 78.2% in 2019. And for the full year, our services gross margin was 34% in 2020, as compared to 30.9% in 2019. Our fourth-quarter research and development expense was $10.4 million or 10.5% of revenues.

an increase of 130 basis points year over year, reflecting the increased spend on new solutions to expand our end-to-end capabilities. For the full year, R&D expense was 10.6%, compared with 9.2% in 2019. Our selling and marketing expense was $19.7 million in Q4 or 19.7% of total revenues, a decrease of 100 basis points year over year, which was primarily driven by a reduction in travel and in-person marketing events due to COVID-19 restrictions. However, these expenses increased by $3.2 million or 230 basis points from the third quarter as we ramped up sales and marketing investments heading into 2021.

For the full year, selling and marketing expense was 18.6% in 2020, as compared to 20.6% in 2019. Our fourth-quarter general and administrative expense was $21.2 million or 21.3% of revenues, versus 21.7% of revenues in the Q4 of 2019. This decrease was driven by information technology infrastructure and other initiatives in 2019 that did not recur but were partially offset by increases in public company operate -- operating costs in 2020. For the full year, general and administrative expense was 21% in 2020, as compared with 20.3% in 2019.

Our quarterly GAAP net income was $200,000 compared to GAAP net income of $4.7 million for the same period last year. GAAP net income per basic and diluted Class A and Class B share was effectively $0, compared to GAAP net income per basic and diluted Class A and Class B share of $0.04 for the same period last year. Non-GAAP net income was $12.3 million, compared to non-GAAP net income of $14.2 million in the same period last year. Non-GAAP net income for diluted Class A and Class B share was $0.08 compared to non-GAAP net income for diluted Class A and Class B share of $0.11 for the same period last year.

Our quarterly adjusted EBITDA was $19.1 million, up 11.2% year over year, while adjusted EBITDA margin of 19.1% was approximately 80 basis points lower than the same period last year, reflecting our investments and our research and development activities, as well as the acceleration of our selling and marketing efforts. For the full year, our adjusted EBITDA was $78.4 million or 20.9% of revenues as compared to $67.9 million or 21.1% of revenues. Turning to our balance sheet and cash flow statement. We finished the year with $303.1 million of -- in cash and cash equivalents, reflecting the completion of our initial public offering where we raised proceeds net of underwriting fees of $423 million which was used primarily to repay our $175 million term loan and pay for operating expenses.

We generated $30.9 million in free cash flow for the quarter, a decrease from $34.8 million in 2019, also reflecting our investment in product development and selling and marketing efforts. We generated $49.6 million in free cash flow for the full year, a decrease from $54.9 million in 2019. Turning now to our guidance for the first quarter of 2021. We expect total revenues in the range of $94.5 million to $96.5 million, representing year-over-year growth of approximately 5.9% to 8.1% and adjusted EBITDA to be in the range of $15.5 million to $17.5 million, representing an increase of approximately $200,000 to $2.2 million compared to the first quarter of 2020.

For the full-year 2021 and consistent with the plan we outlined during the IPO, we currently expect total revenues in the range of $401 million to $405 million, representing year-over-year growth of approximately 7% to 8.1% compared to 2020. Adjusted EBITDA in the range of $68 million to $72 million, representing year-over-year decrease of approximately $6.4 million to $10.4 million compared to 2020. The adjusted EBITDA includes our acceleration of investments and global sales and marketing capacity, new product development and innovation, plus an additional $2 million of increased operating expenses related to the acquisition of Tellutax in January of 2021. As we had anticipated in 2020, we saw a slowdown of enterprise customer buying activity as some of their system upgrades pushed out into 2021 and 2022.

In spite of this, we were able to grow the business during the year. This timing and our acceleration of product development and selling and marketing activities position us nicely as enterprise growth accelerates in 2021 and 2022. This opportunity, as well as continued regulatory changes and increases in complexity, position us for future growth. Additional modeling details underlying the outlook are as follows.

Our share -- our share count at December 31, 2020. We had 120,117,000 shares of Class B common stock outstanding and approximately 26,327,000 shares of Class A outstanding. Additionally, we had approximately 12,647,000 common stock equivalents outstanding with a weighted-average exercise price of $2.21 per share. Our anticipated tax rate is expected to be approximately 25.5%.

Overall, we're pleased with the progress we have made on our strategic initiatives and the performance of our business. And with that, we're happy to open it up now for questions. Operator -- operator, will you please open up the line for Q&A?

Questions & Answers:

Operator

[Operator instructions] Our first question is come from the line of Brad Reback with Stifel. Please proceed with your questions.

Brad Reback -- Stifel Financial Corp -- Analyst

Oh, hey, guys. How are you?

David DeStefano -- Chief Executive Officer

Great, Brad. How about yourself?

Brad Reback -- Stifel Financial Corp -- Analyst

Very good. Very good. Maybe starting from a high level. Competitively, has anything changed out there?

David DeStefano -- Chief Executive Officer

No, Brad. We continue, you know, first and foremost, to compete against the in-house system that's good enough until it's no longer good enough between regulatory change or -- or technology changes that are driving it. We see Thompson Reuters primarily in the global market as our primary competitor when we go in for enterprise deals. And as we go into the middle market, we -- we see -- we see both Thompson and -- and Avalara.

And then overseas, we continue to see Sovos as a -- as a formidable competitor.

Brad Reback -- Stifel Financial Corp -- Analyst

Great. And -- and then switching gears on ARR, you obviously this year was somewhat impacted by COVID it in your commentary on, you know, customers pushing out to '21 and '22. How should we think about when that growth rate reaccelerates?

John Schwab -- Chief Financial Officer

Yeah, this is John. I -- I'll take that Brad. I -- I think -- we think about, you know, growth, you know, kind of steadily building throughout the year, you know, as -- as we ramp up our sales and marketing efforts like we talked about in the Q4 and we start to gain traction there. And so, we think that they'll start to happen a little more, you know, a little more heavily toward the back end of the year as that traction comes into play, as well as the -- the -- the new products that hit the market that David talked about.

So, I would see that a little bit more weighted toward the back of the year -- back half of the year for sure.

Brad Reback -- Stifel Financial Corp -- Analyst

Great. Thanks very much.

John Schwab -- Chief Financial Officer

You bet. Thanks, Brad.

David DeStefano -- Chief Executive Officer

Thank you, Brad.

Operator

Thank you. Our next question comes from the line of Daniel Jester with Citigroup. Please proceed with your questions.

Dan Jester -- Citi -- Analyst

Great. Thanks. Good morning, everyone. So, I just wanted to circle back to something that was said in the prepared remarks.

I think, David, you talked about that you noticed some acceleration in -- in digital transformation impacting you in 2020 but then John talked about sort of some enterprise delays. So, could you just piece out exactly kind of what you're seeing maybe -- maybe small, mid-sized business versus enterprise and how COVID has impacted that and -- and how you see the recovery trajectory going throughout this year? Thanks.

David DeStefano -- Chief Executive Officer

Sure. I'll take a start and then, John, you can jump in. And thank you, Dan, for the question. You know, I think, where we saw acceleration in the mid-market as more companies are adopting workforce and, you know, Salesforce, Workday, and Salesforce as operating systems.

We saw a great opportunity where that complexity of the regulatory environment and their -- their new technologies are creating demand for us. I think that's also where our value prop showed up and why we're able to drive the ARR and our new logos significantly in cloud across the business. Obviously, some of the larger enterprise organizations we did see -- we did see con -- we had a lot of conversations. And while we didn't see good -- good progress, two things of note there.

I think, one, we saw deals where the -- where the large Oracle or SAP implementation maybe got put on hold and we have to deal with that and that'll -- they'll survive with good enough until '21 or '22. And then additionally, you know, it's important to remember, we have a hybrid approach. And so, we continue to see large on-premise deals being sold. And so, that'll -- that -- that's good for us in the long term because when they're ready to migrate to the cloud we're doing great on those migrations when they happen, but we have to recognize that our hybrid approach gives the customer the opportunity to choose what's best for them.

And we think that's still a differentiated part of our strategy.

Dan Jester -- Citi -- Analyst

Thanks. And then just on the 2021 revenue guidance. John, I think you mentioned that, you know, the framework was -- was consistent with the IPO. But, you know, that certainly the economy is a lot different than -- than six to nine months ago and there's a lot more sort of green shoots as we think about how the year progresses.

So, maybe philosophically, how did you think about it approaching the -- the guidance for the full year, and what are your sort of expectations from a -- sort of a macro perspective? Thanks.

John Schwab -- Chief Financial Officer

Yeah. Dan, that's a good question. I -- I think as we think about sort of how things are going to play out as I mentioned when we talked about ARR, you know, the ARR is going to build itself throughout the year. And as you know, as we recognize revenue ratably over the period, it takes a little bit longer for it to kind of pull itself into the, you know, to pull it through our revenue stream.

So, that's sort of how I think about sort of the -- the tracking of it in the tracking of revenue. Yeah, we certainly do see opportunity out there and we're certainly capitalizing on that as well as building -- building our sales force to further capitalize on it. But I think over time, that will continue to work itself into, you know, work itself into 20 -- in -- into 2021 toward the back end. And again, the revenue follows.

And keep in mind, we did have a real nice, you know, we -- we did have a real nice Q4. We did see a lot of activity in Q4, although we were benefited in the fourth quarter by, you know, by about $1.5 of transaction-based sort of true-ups from a volume standpoint. So, when you kind of compare it on a -- on a sequential basis, there's a little bit of that that plays in there as well. But thank you.

Thanks very much for the question.

Dan Jester -- Citi -- Analyst

Thank you.

Operator

Thank you. Our next question comes from the line of Brad Sills with Bank of America Securities. Please proceed with your questions.

Brad Sills -- Bank of America Merrill Lynch -- Analyst

Oh, great. Hey, guys. Thanks for taking my question. I wanted to ask about the cloud.

It -- it -- you had -- you had good results this year, 65% growth in cloud ARR. You know, I think you're -- you're forecasting a deceleration there to -- to 35%. Was the -- the pandemic a accelerant, if you will, for, you know, cloud deployments. In other words, you know, with work remote, it's easier to deploy in the cloud versus on-prem.

And if so, is that -- is that tailwind, you know, in -- in the business perhaps over -- is that implied in the guidance, or is there something else going on with the -- with the deceleration in cloud ARR outlook? Thank you.

David DeStefano -- Chief Executive Officer

I'll start and then John, feel -- yeah, feel free to jump in. You know, I think, you know, fundamentally, it's -- it's not going to be over $100 million base. So, 35% plus growth was we felt a more normalized just top-of-the-trees answer. But I think it's important remember, Brad, we lead everything cloud-first in our sales and we see pretty consistently the overwhelming majority of our new lo -- logos are all cloud deals.

The -- as our customers are expanding on omnichannel and continue -- existing customers continue to grow -- allow us to grow our footprint within their -- their base, those are largely cloud deals. So, I -- we see it as three different tranches. It's the new logos, largely cloud, overwhelmingly cloud the -- the upsells and the new sales to existing customers. I'd say a majority of those are.

And then -- and then existing customers though are still -- still slow to migrate. You know, I think we saw a little bit of acceleration there but nothing material that we would suggest we got a new trajectory for '21 around existing customers migrating off of their on-premise solution.

John Schwab -- Chief Financial Officer

Yeah. And just to add a little bit, Brad. You know, what I would say is that as David and I both mentioned, you know, the growth was about 65% on a year-over-year basis for the full year You know, some of that is impacted by a couple of things. We did have a monster Q4 2019 in terms of our cloud sales and it was really just an absolute banner -- banner-blowout quarter.

So, we certainly are dealing with a tough-comp quarter. And then secondly, keep in mind, we did close on Systax acquisition in January of 2020, so that's also in those numbers sort of pulling that. So, when you look at sort of a little bit of the pullback, that pullback has a couple of things going against that, you know, the -- the acquisition certainly notably being a decent-sized piece of that. So, I just thought I'd point that out as well.

Brad Sills -- Bank of America Merrill Lynch -- Analyst

Great. Thanks so much, guys. And then one more if I may please. Just on -- on some of the -- the headwinds you noticed in the business this year with some of the deals', you know, delays.

Is that largely over? Do you -- do you have visibility for those deals coming back here, you know, with -- with a pandemic and reopening and kind of happening gradually? What would you say there? And thank you so much.

David DeStefano -- Chief Executive Officer

Yeah, I think, you know, in the be -- in the beginning of the pandemic, it was all IT shops, we're all-hands-on-deck to get their entire workforces global. And obviously, large enter -- multi-national enterprises, that was a bigger challenge. We have had, I think, the sales conversations are good going forward here in terms of people getting, as you say, more back to normal in terms of thinking about their IT roadmaps. And we're really pleased with the Oracle OCI and SAP S/4HANA migrations that are now starting to -- to -- to resume.

Those are obviously longer. Depending on the size of the project, those can be, you know, 6 to 24-month implementations of which then we fit in at a certain slot. So, it's really understanding where we are -- where they are and their timing where we best fit into those projects.

Brad Sills -- Bank of America Merrill Lynch -- Analyst

Thanks so much, guys.

David DeStefano -- Chief Executive Officer

Yeah. Thank you, Brad.

Operator

[Operator instructions] Our next question comes from the line of Pat Walravens with JMP Group. Please proceed with your questions.

Pat Walravens -- JMP Securities -- Analyst

Oh, great. Thank you. Congratulations to you, guys. I want to talk about Tellutax and Sal Visca.

So, I guess, Tellutax first. Can -- can you just go over again why you bought it and -- so, it's Eric and Christian, right? Are they both Vertex?

David DeStefano -- Chief Executive Officer

Eric. Yes, Eric joined and -- and, you know, Eric obviously has a steep history in the industry having architected intact technology for years. And we really were pleased with some of the innovations when he had gone out on his own about where he was taking the indirect solutions at that point of need for mobile and IoT-level container where you can really shrink the footprint enterprise solution down into that container which we think will make a very attractive from a deployment perspective for our customers. So, we saw a great value in what they were building and wanted to make sure got that in -- integrated into our products as quickly as possible.

Pat Walravens -- JMP Securities -- Analyst

OK. I say -- I messed up my question. So there were two Erics, right? There's Eric Ruud and Eric Christian?

David DeStefano -- Chief Executive Officer

Yeah.

Pat Walravens -- JMP Securities -- Analyst

OK. Are they both -- are they both joining or you just -- just Eric Christian?

David DeStefano -- Chief Executive Officer

No. Just the technology Eric. Eric Christian.

Pat Walravens -- JMP Securities -- Analyst

OK. And -- and his role is going to be what?

David DeStefano -- Chief Executive Officer

He's working in -- in our innovation group, driving the implementation, you know, as an architect -- as a lead architect around driving the integration of that product into our -- our -- into our product stack.

Pat Walravens -- JMP Securities -- Analyst

OK, great. And then, at the same time, you have Sal Visca coming in. So, I'm sure you talked to a gazillion candidates. Why did you pick this one and -- and, you know, what -- what are you -- what are you going to tell him his top priority is coming in here?

David DeStefano -- Chief Executive Officer

Yes. Sal has an extraordinary background and experience that -- he spent the last 10 years in e-commerce, which is really critical to the front office space that we're in, you know, we see a great growth opportunity where complexity is accelerating. So, his back -- he used to be the CTO of Business Objects. So, he has played in the data and BI space, which I think there's an opportunity there for us given the -- the large data sets that we touch and -- and interact with regularly.

And then, he spent some time in enterprise software so he certainly understands are -- through his experience at SAP or ERP and back-office footprint and the need to be, you know, at scale for the type of enterprise customers. So, Sal brings just a -- a great wealth of innovation and experience to our team and we -- we just couldn't be any more excited to have him join.

Pat Walravens -- JMP Securities -- Analyst

Great. And -- and what would you say the top priority is for him coming in here?

David DeStefano -- Chief Executive Officer

You know, Sal is -- is focused across everything I just said. He's -- he's accelerating our -- our extension in our e-commerce platform area. He's accelerating our product roadmap. He's got some nice innovation about how we can accelerate certain deliveries of products.

And he's also very much focused on some of the inorganic things like Tellutax and Systax and other things we're looking at, given his background in M&A about how we can accelerate that. So, those are probably his top three priorities.

Pat Walravens -- JMP Securities -- Analyst

OK. Perfect. Thank you.

David DeStefano -- Chief Executive Officer

Thank you, Pat.

Thank you. Our next question comes from the line of Chris Merwin with Goldman Sachs. Please proceed with your questions.

Chris Merwin -- Goldman Sachs -- Analyst

OK. Thanks very much for taking my question. I wanted to ask about net retention. I know that dipped slightly in the quarter.

I imagine that's the impact, I guess, of lingering effects from the pandemic as we move into 2021 here. Just curious how we should be thinking about the trajectory of that metric. I know cross-sell is a very important focus for you all with the -- with the breadth of products that you have. So, just curious about any comment you could share about the trajectory of that metric.

Thank you.

John Schwab -- Chief Financial Officer

Yeah, Chris, thanks very much for the question and -- and a very good one at that. I think you're right as -- as we looked at sort of the decrease -- a little bit of a drop here that we saw in the fourth quarter from an NRR standpoint, it's really driven by two things. You know, it really it's the cross-sell migrations and the additional -- the additional volume we get with existing customers. So, they were the two pieces that fell probably similarly each side kind of taking that down a little bit as we think about kind of where we are from that standpoint and -- and think how this will kind of impact going forward.

As I mentioned, you know, since this is largely driven by ARR activity, we'll start to see some of that ARR pick itself up in the back half of the year. And as that picks itself back up, we'll start to see improvements in this area, but it'll -- it'll moderate, you know, it'll moderate kind of where it is now maybe down a little bit but then start to move itself back as we get more volume -- more volume coming in through ARR. But, you know, again, we feel pretty good about it again. Our customer, you know, our -- our customer base is very strong, it's very durable, they continue to -- continue to buy additional entitlements and additional enhancements to the products that they have and so we feel pretty good about it as we move through.

And again, as we continue to -- as we continue to migrate certain customers across the -- across the map from on-prem to the cloud, there's an opportunity there as well.

Chris Merwin -- Goldman Sachs -- Analyst

Great. And maybe just a follow-up on that point on migration. I think you said that in the prepared remarks, gross retention was around 91% and there was some impact to that number from cloud migration. So, like you said, you're obviously keeping the customers and migrating them in the cloud.

Just want to make sure I understand the puts and takes around how migration would impact your gross retention rate.

John Schwab -- Chief Financial Officer

Yeah. Chris, great -- great point. As we measure and we monitor sort of our GRR to NRR that walk -- that I've walked many people through, you know, when customers move out of one -- out of one solution into another solution, it shows initially getting to GRR that they have left that solution so I chose it as a loss. And then, when it comes back in -- when it comes back in as a new sale, it shows and it adds into the NRR.

So, it's a decrease for the GRR and it's included in the increase in the final NRR number. However, it shows -- it shows it going down when you get to the GRR calculation. That's about 300 basis points and because of the conversion that -- that movement there, that movement certainly impacts GRR initially, and as people look at it and say, hey, how can you guys be at 91% with such stickiness in such enterprise -- in such enterprise software. It's really -- it's being impacted because of that move on an overall basis.

If you did it on a customer basis, I think, it would tell a bit of a different story certainly as -- as that movement takes place. Does that make -- does that clear that up a little bit?

Chris Merwin -- Goldman Sachs -- Analyst

Definitely. Thanks very much.

John Schwab -- Chief Financial Officer

Great.

Operator

Thank you. Our next question comes from the line of Stan Zlotsky with Morgan Stanley. Please proceed with your questions.

Stan Zlotsky -- Morgan Stanley -- Analyst

Perfect. Thank you so much, guys, and thank you for taking my questions. Maybe just following up on Chris's question before. On the -- the cloud migrations right now, how are you thinking about it into 2021? And, you know, how much does that play into the 35% guidance that you have for cloud subscription revenue -- revenue growth in the year? And then have a quick follow-up.

John Schwab -- Chief Financial Officer

Yeah. I guess -- you want to? OK. I'll -- I'll just start and see -- Stan, as we build and we model this out, we didn't take any significant changes in assumptions from cloud migration because again as David had mentioned in some of his remarks, you know, we're not really pushing customers and accelerating customers to move over to the cloud. If the opportunity presents itself, you know, we're certainly going and talking to them about that.

But there's no forced migration that's taking place. And so, our anticipation for cloud migrate -- from migration to the cloud from on-prem is really consistent with sort of how it's been, you know, the level that it's been in the past. So, we're not anticipating any big jump there in terms of kind of how that activity plays.

David DeStefano -- Chief Executive Officer

Just on a bigger base now. So, it's for sure we try to be a little more thoughtful about what would be a good cloud growth rate and -- and feel like we should be able to do 35% plus.

Stan Zlotsky -- Morgan Stanley -- Analyst

OK. Perfect. And then, did -- so, this is a little bit -- a little bit nuanced, but if we do the math of taking the -- you're your average revenue per customer that you disclose and you divide -- divide that into the ending ARR, it looks like the customer account has been declining for the last three quarters. Is that just -- is that just a function of maybe some churn at the low end? Is there is -- there something going on with the calculation that we need to be mindful of? And, you know, just anything that can help us with that would be great.

Thank you.

John Schwab -- Chief Financial Officer

Yeah. I think, Stan, as you heard, there's nothing going on with the calculation. I think, a lot of it really has more to do with the churn at the lower end, a lot of smaller -- smaller type customers. There is a little bit more churn there perhaps at the higher end, but I think, that's what you're seeing.

We're doing, you know, some levels of consolidation as we think about -- as we think about that -- that, you know, that -- that can impact it slightly. But I wouldn't tell you that our number of customers is really dry -- is dropping precipitously at all it really more has to do with some of the churns at the low end because, again, as David talked about, we continue to see a rise in the average ARR per customer.

Stan Zlotsky -- Morgan Stanley -- Analyst

Got it. Thank you so much.

Thank you. Our next question comes from the line of Bhavan Suri with William Blair. Please proceed with your questions.

Bhavan Suri -- William Blair & Company -- Analyst

Hey, guys. Thanks for taking my question and congrats on that cloud of growth. That was -- that was pretty solid there. I want to touch a little bit on sort of a -- a more strategic question here which is you've seen a bunch of consolidation or at least you start to see much consolidation in that office of the CFO space whether it's compliance and tax, whether it's ARP and tax, whether it's treasury and tax.

How do you think about your role there and sort of maybe -- maybe -- maybe help us again? I know you can't give us an exact product road map, but how do you think the company starts to address that consolidation, that tax space in say, the next three to five years?

David DeStefano -- Chief Executive Officer

It's a very good question, Bob. I mean, it is -- it is an evolving world for sure. I think it's important to note that, you know, a big part of our element is also in the IT function. We play very heavily because of the line item invasiveness of our product.

It's -- it's very much -- so at the income tax level, you're seeing more of that consolidation in the indirect tax space. That consolidation plays out a little differently because we're often apart of -- regulatory and compliance is often a different part of the organization than the CFO. That said, I think, because of the strength of our partnerships with the big -- the global big four and the other big alliance firms as well as the technology partners, I mean the deep integration we have with them, it positions as well as those conversations continue to evolve. And I would also tie it back to some of the conversations that were asked previously about Sal Visca joining us.

I think we see an opportunity for sale to bring some -- some nice innovation there and expanding our -- our product suite that will help us in that space.

Bhavan Suri -- William Blair & Company -- Analyst

Thanks, David. And then, maybe -- maybe one from John. This may have two parts. John, so, quickly on the NRR which is 176%.

Typically you guys have a 5% price increase annually. So, maybe help me bridge that. I think it might just be the churn that plays into it but help me understand that, do you see any pressure on that 5% price increase this year? Did you give any concessions, did you wait a little bit? How -- how should we think about that? And then, the second part is -- is there any way to quantify the tailwind from the things you're seeing in Oracle and SAP and HANA? Like is that going to, you know, it was obviously a headwind this year, but can we think over like not even next year but over 24 months, does that provide, you know, 200 to 300 basis points? How should we think about that? Thank you.

John Schwab -- Chief Financial Officer

Yup. No. Thank you for the question. Let me take the first one first.

You know, as it relates to sort of the NRR and you think about the 106% and you say, hey, you know, about a 5% price increase. Keep in mind as we build -- as we build that, that 5% price increase really has to start with the GRR number. It starts with a 91 and stuff up. So, we've not seen any impact from a pricing standpoint our ability to pass price increases along to our customers is very consistent with where we were last year.

As I look -- I look at the numbers and so there's really been no impact there in terms of how that's gone. So, we feel pretty good about, you know, the product we deliver the -- the tax content that gets delivered our customers continue to buy more and -- and get that. And because of that, they continue to invest in our product. So, again, price increases unaffected by anything.

And again, the walk just again to the point that I made earlier is a little bit lower from across -- the cross-sell migration as well as additional volumes that are going through. Again, as people, you know, as volume have slowed for certain of our customers so not a real big change there from -- from, you know, from a price increase standpoint, really, in the other two pieces that drove it. So, that's sort of how that walk -- that walk goes. I guess from the other standpoint kind of the tailwinds that you talked about.

Yeah. Again, as I mentioned in my remarks, we did see a little bit of a pullback from those big enterprise customers. Listen, I think, we don't see, you know, as we lookout. we think those opportunities are still certainly there and as those movements and that migration and that activity takes place, that as they migrate their systems to other things, that should provide an opportunity for us to be in the game and certainly driving -- driving additional revenue as those things come to be.

Bhavan Suri -- William Blair & Company -- Analyst

Thank you. Our next question comes from the line of Samad Samana with Jefferies. Please proceed with your questions.

Jordan Burick -- Jefferies -- Analyst

Hi, this is Jordan Burick on for Samad. Thanks for taking my question and congrats on the strong quarter. So, I just wanted to follow up on Pat's question. Last year you acquired Systax, and now this year Tellutax.

Could you just remind us of your status on your M&A?

David DeStefano -- Chief Executive Officer

You know, Jordan, appreciate you joining the call. You know, we continue to see opportunities to expand and it was -- it was part of our decision going public was to have more resources to make acquisitions. As we expand globally, I think, there are a lot of opportunities to add content and select technology niche -- niche and tuck-in acquisitions that will support the end and end suite that we continue to fill out. As complexity continues to show up in the tax department, they're now looking for cross-border, customs and duties and other types of capabilities going forward.

And so, we, you know, we're consciously engaging in the market around those -- those opportunities.

Jordan Burick -- Jefferies -- Analyst

Great. Thank you.

David DeStefano -- Chief Executive Officer

Thank you. Our next question comes from the line of Josh Reilly with Needham and Company. Please proceed with your question.

Josh Reilly -- Needham & Company -- Analyst

Hey there guys. Thanks for taking my question. So, if we look at the ARR growth over the last several quarters and now your subscription revenue guidance for Q1 in the year. I'm just trying to understand the delta there.

It seems a little bit wider than what I would expect. Is it primarily conservatism around the macro environment right now or how should we think about the puts and takes there?

John Schwab -- Chief Financial Officer

Yeah, I mean a couple of things, Josh. Thanks for the question. Again, we feel pretty -- we feel good about what we've seen from a marketplace in terms of the activity that's out there. The ARR growth is good as we think about sort of the quarter and we think about the growth in the quarter and as it translates into guidance.

A couple of things first, keep in mind services does take a little bit of a dip in the first quarter. We have real strong -- we had a real strong Q4 from a services standpoint with customers trying to get some year-end implementations up and running. So, that was really good for us. Again, on the backside of that sort of drops a little bit from a total revenue standpoint from, you know, from an invoicing standpoint when we take a look at, you know, at 2020, we had a really nice.

And -- and there were some -- there were some anomalies a little bit in Q4, as I had mentioned, some of that transaction-based pricing true-ups that happened in the fourth quarter not giant but certainly impacting as we move forward. So, we continue to see momentum, you know, from -- from a, you know, from a revenue standpoint that continues to grow. But again some of the -- some of the activity and a little bit of the slowness and some of that push out that I talked about in my remarks that we saw in 2020 sort of manifest itself in revenue sort of as it rolls into 2021. That's how I would summarize it.

Josh Reilly -- Needham & Company -- Analyst

OK. Got it. And then, just a follow-up. Which go-to-market technology partners have been strongest in driving new business during kind of the COVID era.

Is it, you know, ERP obviously took a hit maybe at the high end but in the mid-market ERP -- is that more of a driver and then point of sale procurement? Just trying to understand, you know, what the drivers are there? And then, do have any -- expect any shift in those technology partners driving business in the post-COVID macro?

David DeStefano -- Chief Executive Officer

You know, I certainly think we're seeing good momentum in, you know, Salesforce and Workday and -- and sort of the -- the emerging as you say, mid-market players. Also at the enterprise level, we play with both of them very wealthy enterprise level. So, I think that -- that -- that space axiomatic -- all have been drivers of -- and Microsoft would be our primary drivers in the mid-market. The relationship we have it odd and not and some of the additional good partners that we've added in the Microsoft space have played well to be drivers.

Certainly, going forward the procurement and e-commerce space is where we see great opportunity for expanding relationships and integrations and that is something we're actively -- some of the partnerships we added in '20 -- in Q4 were specific to that space.

Josh Reilly -- Needham & Company -- Analyst

Got it. Thanks, guys.

David DeStefano -- Chief Executive Officer

Happy to, Josh.

Operator
