Vlad Shmunis -- Chief Executive Officer, Founder and Chairman

Good afternoon and thank you for joining our fourth quarter earnings conference call. We delivered an outstanding fourth quarter with continued strength in mid-market, enterprise and channel. Additionally, we had a number of major announcements and achievements during the quarter.

First, I am pleased to announce that we finished the year achieving an important milestone, namely we have surpassed our long-term goal of $1 billion annual revenue run rate ahead of schedule. This is a significant achievement for RingCentral and we continue to be the largest and fastest growing pure play UCaaS vendor.

In October, we announced our strategic partnership with Avaya. In November, we announced that we expanded our relationship with AT&T. And today, we announced our first strategic system integrator partnership with Atos. On the leadership team, we added Anand Eswaran as President and Chief Operating Officer. I'll expand on this key announcement later after a review of Q4 results.

Revenue and non-GAAP EPS exceeded the high end of our guidance. Key drivers continue to be mid-market, enterprise and channel. We continue to see strong contributions from our vertical market initiatives focused on financial services, healthcare and education. We also saw another strong quarter from contact center.

Key metrics for Q4 were solid across the board. First, total revenues grew to $253 million. This is a 34% increase year-over-year and is above the high end of our guidance range. Mid-market and enterprise continues to be a key driver of our performance. We define mid-market and enterprise as $25,000 or more in annual recurring revenue or ARR. This grew 59% year-over-year and is now a $479 million business.

Enterprise defined as customers with $100,000 or more in ARR grew 71% year-over-year to $293 million. Channel ARR grew 53% year-over-year to $300 million. Overall, 2019 was a transformational year for RingCentral as we extended our leadership in the UCaaS market.

Looking forward, our technology leadership, experience management team and unique strategic partnerships put us in a better position than ever to maximize our opportunities in the $50 billion plus UCaaS market.

On that note, I'd like to welcome Anand Eswaran to the RingCentral team as President and Chief Operating Officer. Prior to RingCentral, Anand was Microsoft's Corporate Vice President for Global Enterprise Business. Anand will be responsible for leadership and execution across product, engineering, sales, marketing, services, customer care, operations and human resources.

I'd also like to take a minute now to express our gratitude to Dave Sipes. Dave announced that he will be retiring from the company at the end of Q2. Dave have played a pivotal role in retentions journey from an approximately $10 million revenue company to our current $1 billion run rate. Dave, we wish you all the best in the next stage of your journey and look forward to your continued friendship and mentorship.

I'll now provide an update on the strategic partnership front. First, the Avaya partnership. We attended Avaya's Engage User Conference last week where we showcased a first look of Avaya Cloud Office by RingCentral or ACO. Feedback was positive from customers and channel partners. RingCentral and Avaya team are working together well. ACO is well on track for scheduled launch at the end of this quarter. The marketing sales and support teams have made solid progress to ensure customer success and training efforts are well under way with sales and channel partners.

Next, AT&T. In November, we announced that we expanded our relationship with AT&T. AT&T made office of Canberra RingCentral a lead offer for UCaaS as part of its voice and collaboration portfolio. It has been a few short months, but we are already starting to see encouraging trends that are exceeding our initial expectations.

And today, I'm excited to announce our third strategic system integrated partnership with Atos. Atos is a global leader in enabling enterprise digital transformation with annual revenue of approximately $13 billion. The partnership will help extend RingCentral's reach into large enterprise accounts moving forward with digital transformation initiatives. As part of this partnership, we will introduce a co-branded UCaaS solution. This co-branded solution will be a key part of Atos' digital workplace solutions.

To wrap up, 2019 was a stellar year. We are still in early innings of the global cloud communications transformation story. We're well-positioned to further extend our leadership with our commitment to innovation, customer-first mindset and the unique strategic partnership strategy. With this momentum in place it has never been more clear that the cloud is winning and RingCentral is winning in the cloud.

Now, for some color on Q4, I will turn the call over to our new President and COO, Anand Eswaran.

Anand Eswaran -- President and Chief Operating Officer

Thank you, Vlad. I'm humbled and energized to join Vlad and the RingCentral team. We are at an inflection point in the way we communicate, collaborate and work. As every company transforms to be a digital business and workplace, RingCentral is uniquely poised as the leader in UCaaS to partner with these companies in their digital journeys. I am so excited by the large opportunity ahead of us to transform business communications globally.

I also want to thank Dave for building an exceptionally strong innovation and go to market team which has taken RingCentral to a $1 billion run rate. I have enjoyed getting to know Dave really well as we spend every minute together partnering and working through the transition. Thanks to Dave for the help and support.

I will now provide some color on Q4. Q4 was again a strong quarter. It was driven by strength in mid-market, enterprise and channel. We continue to win based on our superior platform and differentiated go-to-market capabilities. First, our platform, which integrates voice, video and team messaging continues to resonate with our customers. Our open platform ecosystem expanded to nearly 30,000 developers. I'm also excited to announce that we surpassed 3,000 certified integrations. The ease and flexibility with which our customers can integrate business applications with our communications platform is a game changer. In fact, over 70% of our seven-figure wins in Q4 cited open platform as a key capability in their decision to go with RingCentral.

An example of their open platform and mobility, their key is a Fortune 500 utility company with approximately 8,000 users. They replace legacy on premise Cisco Systems with RingCentral Office. Integration of multiple business applications between central office including Office 365 and Workday was important for the customer.

Additionally, the ability of field employees to be connected to a single enterprise communication solution using rugged Caterpillar mobile devices was important. We saw up market strength in our focus vertical markets, our financial services, healthcare and education. In aggregate, during Q4, these accounted for over 40% of our seven-figure events.

In financial services, we had a standout quarter. First, we are excited to announce event with Arch Capital, a global leader in providing specialty, insurance and reinsurance solutions. We are pleased to see a global 2,000 multi-billion dollar enterprise like Arch Capital select RingCentral for their global cloud communication needs.

Another financial institution win in the quarter was Credit Human, a large credit union, based in San Antonio with members across the country. The ability to integrate a complete unified communications platform with key financial services applications, including Jack Henry was an important differentiator in securing this nearly 1,000 seat win. In healthcare, we secured 4,500 user win with Aveanna Healthcare, the nation's largest provider of pediatric home care. They wanted to standardize to a single communications experience across approximately 240 locations, including headquarters and regional offices. Our ability to provide a single unified solution with high reliability was key to this win.

In addition, our mobile capabilities were a strong fit with the home care business model. We also signed 3,600 user win with US Renal Care, a leading provider of dialysis services. This customer needed a single communication solution across more than 300 locations. They also needed the ability to integrate with existing paging systems. In higher education this quarter, we had a win with National American University. Our unified platform with integrated team messaging and the ability to implement custom emergency workflows were key driving factors in this win.

Let me now provide a brief update on the success we are having with contact center. Over half of our seven-figure wins included contact center in Q4. Contact center is a key element of our land and expand strategy. For example, earlier this year, we secured a 10,000 seat win with a Fortune 1000 multinational software company. In Q4, this customer added 150 contact center seats. Also, earlier this year, we secured a nearly 6,000-seat RingCentral office win with Crawford & Company. And in Q4, we added over 400 contact center seats.

Additionally, in Q4, we delivered a marquee win for Engage Digital, a native digital customer engagement solution. Richemont is a well-known Switzerland based luxury goods holding company of many luxury brands, including Montblanc. They needed a single digital customer engagement platform across eight of their luxury brand divisions. Richemont plans to deploy Engage Digital globally on several digital channels such as Facebook, Instagram and Messenger. We also continue to see increasing traction with our native Engage Voice outbound blended solution with a record number of wins last quarter.

Now, for the financials, I will turn the call over to our Chief Financial Officer, Mitesh Dhruv.

Mitesh Dhruv -- Chief Financial Officer

Thanks, Anand, and welcome aboard. Looking forward to working together as we scale RingCentral to the next level. I'd also like to express my gratitude to Dave for the terrific partnership over the years.

Good afternoon, everyone. 2019 was a solid year on several key fronts. First, we exited the year with a revenue run rate of over $1 billion. Second, we grew 34% with an operating margin of over 9%, executing above the rule of 40%. We delivered on the $1 billion and the rule of 40% a year ahead of commitment to our shareholders.

These milestones are a testament to the large market opportunity as well as RingCentral's focus on consistent execution. We believe that the rule of 40% is a key metric to evaluate profitable growth across SaaS companies and is a high bar we will strive to sustain. Third, we are winning larger enterprise customers with well over 100 seven-figure TCV deals for the year.

And finally, we signed an industry redefining partnership with Avaya. Our fourth quarter kept the year with strong performance on all key financial metrics. Total ARR grew to $960 million, up 32% year-over-year and ARR for RingCentral office, our core UCaaS solution grew to $877 million, up 36% year-over-year. Key drivers continue to be mid-market and enterprise with a record contribution from channel partners. Mid-market and enterprise had another strong quarter, but ARR up 59%. This was bolstered by enterprise ARR growth of 71%, driven by digital transformation momentum at large scale customers. Overall, mid-market and enterprise yet again accounted for over 60% of new bookings.

Higher up market mix is a positive indicator of our profitable growth, given better lifetime value. Channel partners are a key element of our strong momentum with larger customers. Channel ARR reached $300 million in Q4, up 63% and also accounted for a record number of our seven-figure TCV deals. We continue to broaden our channel network and deepen relationships with key partners such as Carousel, Telaris and Westcon.

Upmarket and channel drove strong results across the board in Q4. Total revenue grew 34% to do $253 million. Subscription revenue grew 33% to $229 million. Non-GAAP subscription gross margin was 82%. Non-GAAP operating margin was 9.6%. Non-GAAP EPS of $0.22 was above our guidance. Operating in free cash flow includes approximately $37 million of one-time payments stemming from our recent partnerships. Excluding these items our free cash margin would have been approximately 8%.

Now let me provide some financial color on our recent partnerships that we believe to be additional drivers of our long-term performance. Starting with the latest news first, as we announced today, Atos will become a strategic SI partner to RingCentral. We expect RingCentral to accelerate its large enterprise reach by joining Atos' digital transformation portfolio. Given the sales cycle for large enterprise, we are not assuming much contribution from Atos in 2020.

And now, for our industry redefining Avaya partnership. ACO is on track for launch at the end of this quarter. We have received positive feedback and interest from both customers and partners alike. As we mentioned before it will take time to ramp the go to market motion following the launch. As such, we continue to expect revenue contributions from ACO to start toward the end of 2020.

Now, to the 2020 financial outlook. We expect total revenue to be between $1.125 billion and $1.135 billion for an annual growth of 25% to 26%. We expect non-GAAP EPS to be $0.93 to $0.94 based on a fully diluted share count of $94.5 million. This reflects additional imputed shares from the convertible debt due to stock price appreciation as well as shares issued to Avaya in November. Excluding these items, our EPS guidance range would have been $0.04 higher.

In summary, 2019 was an outstanding year for RingCentral. Our industry-leading product innovation is driving increased demand from customers, channel and strategic partners. Longstanding industry leaders with vast go-to-market are selecting RingCentral as their UCaaS solution for their customers. With these tailwinds, we are more confident than ever in our ability to continue to lead in this $50 billion UCaaS market.

With that, let me turn the call to the operator for Q&A.

Questions and Answers:

Operator

Thank you. We'll now be conducting a question-and-answer session. [Operator Instructions] Our first question today is coming from Bhavan Suri from William Blair Your line is now live.

Bhavan Suri -- William Blair -- Analyst

Hey, guys. Can you hear me OK?

Vlad Shmunis -- Chief Executive Officer, Founder and Chairman

Yeah.

Bhavan Suri -- William Blair -- Analyst

Great. Congratulations. It was a phenomenal, phenomenal end to the year. And you've beaten revenue nicely in consistency over the many, many years I've covered you, but you absolutely crushed it to beat both percentage and total volume wise I think it's the biggest that I've ever seen. I guess maybe Mitesh starting off with you, just drivers to just the strength of the upside in performance here on the top line and subscription would be helpful.

Vlad Shmunis -- Chief Executive Officer, Founder and Chairman

Thank you, Bhavan, for the kind words. The beauty of having multiple drivers in the business model is that not every driver needs to work every time. But this time, we did have strength across the board. I'll hit the hotspots on the drivers here Bhavan for you. So the first one is a large deal momentum and new logos within that. We did have record number of over 30 deals which are seven figures or more this quarter and 70% of those deals were net new logos, which actually exceeds lend and expand going forward. So, that's point number one.

Within -- point number two is strong upsell in the quarter. We did see very consistent upsell in the quarter. And again, over 40% of our new business came from existing customers. Third one is our booking linearity which was a surprise to our expectations at least where we had a faster start to Q4 than usual Q4s. And this is despite the fact that we are going further up market, which may be an indication of shortening sales cycles at the margin and plus our push in the vertical side. So that's number three.

And last is channel where we did have a very strong quarter on the channel. 70% of the deals over a $1 million came from the channel. So, those are three or four drivers that really led to the upside. Now, going forward, we are layering on more growth dials like Avaya, like AT&T, like Atos, which will provide even further long-term durability to our growth story.

Bhavan Suri -- William Blair -- Analyst

That's really helpful, Mitesh. Thanks. Then one quick one for Anand. Just -- as you think about RingCentral today, obviously Vlad and Mitesh and team have done a really nice job moving from really small businesses to mid-sized businesses, enterprise, your history -- again, with SAP and Microsoft, with very large enterprise, as you think about sort of where RingCentral might be, no near term but five years, just I'm trying to get some color on how you think about the go-to-market changes or the go-to-market layering you'll do to sort of drive even further growth within the enterprise. What do you think the set up today will get you there without sort of incremental investments or changes? Thank you.

Vlad Shmunis -- Chief Executive Officer, Founder and Chairman

Well, that's a great question. So, one of the key things you said is important. It's not go-to-market changes as much as layering, because what we have is a great foundation. And we have people continue to accelerate the growth we create out of the mass market segments. The growth layers we expect, Mitesh walked through some of them, our partnerships with Avaya is going to be a big contributor of growth as we look ahead. And that's going to span all customer segments. We expect the same benefits to come in through the other relationships we are creating, and we talked about Atos right now.

And then, the other layers, which we will start to look at even more broadly, is one expanding on getting deeper into verticals and starting to actually create a little more density of focus and coverage, but also innovation and IP from a vertical standpoint. That's going to be key. And that will allow us to then actually go and penetrate upmarket, basically mid-market and enterprise, in a much more broad strategic manner. So, partnerships and basically vertical focus is going to be some of the keys on how we look at adding layers to growth.

Bhavan Suri -- William Blair -- Analyst

Got it. Got it. Helpful. Thanks and congrats, guys.

Operator

Thank you. Our next question is coming from Terry Tillman from SunTrust Robinson Humphrey. Your line is now live.

Terry Tillman -- SunTrust Robinson Humphrey -- Analyst

Yeah. Thanks for taking my questions and I'll echo the congratulations. I guess, maybe Mitesh, first question for you just relates to historically the philosophy of profitable growth. You obviously have some new growth vectors here and then layering on more investments in the existing go-to-market. But I'm just wanting to hear about the balance of these investments but also showing sales efficiencies. I'd love to get a perspective on sales efficiencies and maybe pinpointing where you might see some of that if you're going to see some of that over the next 12 months. And then I have a follow-up.

Mitesh Dhruv -- Chief Financial Officer

Thanks, Terry. Yes. For us, it's always about disciplined investment and profitable growth as you pointed out to capture this large market. If you look at the go-to-market motions, there are three key areas of investments for us, one is direct site, one is,channels and then one is, as you call, layering of the strategic partners. So, let's double click on each one of them. If you look at the direct side what we are seeing is that we are able to maintain our sales and marketing efficiency year-over-year despite the fact that we're going upmarket, which is typically longer sales cycles.

The reasons for that are, one is a higher percent of our reps are ramped in the segment, which lends to more productivity. And if you actually look at the -- the highest end segment within the enterprise side, we our reps are producing about 52% more year-over-year. So, those two vectors are playing really nicely.

Then if you look at the other two which is our channels and strategic partners both of these growth come at very accretive growth economics to the overall margin profile for 2020, given the lower upfront cost we have to do and lower churn. So if you add all these three motions together they're actually helping our efficiency. And as we further go up market, and they're actually freeing up dollars for us to invest in the future. So, it's a virtuous cycle for us Terry.

Terry Tillman -- SunTrust Robinson Humphrey -- Analyst

That sounds great. And I guess as it relates to these newer or expanded partnerships, I think you laid it out well in terms of Atos, don't expect really much this year because of longer sale cycles. Avaya will start ramping, but let's go back to AT&T. I'd like to get an update on that. In terms of just the -- just the increased emphasis by them to actually push your product, you said you've seen some early interesting activity but I'm curious how material could this expand the relationship with AT&T be this year? Thank you.

Vlad Shmunis -- Chief Executive Officer, Founder and Chairman

Yeah. For AT&T, yes, it could be a materially new driver for us. We have not dialed in much in 2020 here. It's going to be stabilizing, but at the last go around it was a $50 million business. So, given the new expanded relationship and them choosing us to be a lead provider, this could be a broader one this time.

Operator

Thank you. Our next question is coming from Heather Bellini from Goldman Sachs. Your line is now live.

Heather Bellini -- Goldman Sachs -- Analyst

Great. Thank you so much. I had a question, Vlad, just you mentioned that at the Avaya meeting, the partnership meeting last week that you met with a number of partners and customers. We're just wondering what feedback you've got and if there's anything you can share with us in terms of whether it be specific industries that maybe showed the most interest or size of customers. And then, I had a follow up question on that just related to the fact that if you look at the Avaya SMB customers that are currently paying where -- can you walk us through kind of how to think about the incentive structure for those people to move over to ACO? Thank you.

Vlad Shmunis -- Chief Executive Officer, Founder and Chairman

Sure. Yeah. Hi, Heather. So, OK, let's do that in-depth for you, like you said. So, we and me personally, met with two or four of their top most partners. Everyone was universally positive. Frankly, a major message was, quarter-on-quarter what took you guys so long? The field clearly once a cloud based pure cloud product from Avaya and here it is. There was really no push back. One of the partners in particular, and it's a major one, was basically saying that hey, we're all in. We are not so much even interested in offering anything but ACO to the customer base so that was great for us to hear. I mean people have questions as to the logistics but by and large we're able to handle those.

So I would say that there are no red lights, not even the yellow lights at this point. I mean it's just people are just waiting for the product to really be there. And most of our conversation really was look are we providing enough training. Please tell us sort of what else what other supporting materials you need like that. So, it's just operational for the tactical stuff but nothing, nothing at all negative or even inquisitive on the product side or overall partnership.

Heather Bellini -- Goldman Sachs -- Analyst

Great. Thank you.

Vlad Shmunis -- Chief Executive Officer, Founder and Chairman

All right. Thank you. And as for the second part of your question what is the incentive to ACO customers, should I draw that?

Heather Bellini -- Goldman Sachs -- Analyst

Well, it was more like -- a big question that people have is the product going to have the most success at first with the non-paying customers of Avaya in the SMB channel or could it be that the functionality of ACO for the existing paying SMB customers is vastly better so like they might actually be the easier ones to convert at first. I'm just trying to think through kind of that and the potential incentive for them just from a functionality standpoint. Thank you.

Vlad Shmunis -- Chief Executive Officer, Founder and Chairman

Yeah. I just want to be sure, no, very fair question. I want to be a little bit nuanced here. There is no such thing as a non-paying Avaya customer, OK? When people say paying versus non-paying I think they mean maintenance contracts or not but even people who do not pay maintenance are very much paying customers. It's just that they're paying Avaya directly but they are paying to a number of service providers to light up their box and either they're paying maintenance to someone else, maybe the channel partner, maybe it's another maintenance recognition organization or maybe they are just self-insuring. But to keep up a corporate PBF does take money. That stuff does not run for free even if you take initial capex depreciation out of the equation.

So, at a high level, answer is, and we highlighted it, but I'll reiterate we highlighted. When we were first introducing the partnership, our core belief is that we can come in even into a customer that is sitting on fully depreciated hardware and still make a business case to where they get all of the par off the cloud and our industry-leading products, which is, as you will know, has world's best -- most best received voice, business voice, but also have messaging, have video, have open platform, have largest available international footprint and they can get all of that for no more than they are paying now to even keep up the legacy technology. Okay?

So, hopefully that answers the question. Now, having said all of this, just as a reminder to everyone, much of the base is really covered by their partners. So it's really whomever partners find easiest to get through, and we are just following the lead. And certainly -- so the anecdotal evidence seems to suggest that it just cuts across the board. It's people paying maintenance as well as those who don't. Because in the end people want to go from legacy on brand to the cloud so it doesn't really matter. The few dollars a month they may or may not be paying to Avaya for maintenance doesn't really matter, given the overall productivity enhancements that Ring and Avaya Cloud by RingCentral has to offer.

Heather Bellini -- Goldman Sachs -- Analyst

Great. Thank you very much, Vlad.

Operator

Thank you. Our next question is coming from Brian Peterson from Raymond James. Your line is now live.

Brian Peterson -- Raymond James -- Analyst

Congratulations, gentlemen. And Anand, welcome to the call. So, I wanted just to go back to last comment on AT&T ramping earlier than expected. Clearly, that's been a large relationship in the past. I just want to be clear on what's baked into that guidance in 2020 maybe beyond from the AT&T relationship?

Mitesh Dhruv -- Chief Financial Officer

Yeah. Thanks, Brian. Terry asked about this question as well. So, what we -- financially we saw an uptick sequentially in bookings by about 15% or 20% after AT&T made the lead provider. So, that was sort of a change -- step function change we saw. Overall numbers from the bookings are still small, but given the new business growth we are seeing, the overall installed base has stabilized now. And it won't be a drag to growth as in the previous year. So, it should overall -- it should help the financial performance offerings overall going forward. And we are looking forward to build up on successes with deepening the verticals, NGOs there and AT&T.

Brian Peterson -- Raymond James -- Analyst

Got it. Thanks, Mitesh. Anand, maybe just one for you. Any thoughts on how you could target some of the key verticals here in RingCentral, just be useful to kind of here how you're thinking about that playbook over the next few years? Thank you.

Anand Eswaran -- President and Chief Operating Officer

Absolutely. It's a great question. So, the way we're looking at it is, one, partnerships are a key avenue to actually targeting verticals. So, that's why we talked about the strategic partnership with Atos and you can expect to see strategic partnerships as our key vector. And when we work with Atos, we are working in how they work with their customers and their digital transformation journeys by vertical, and we are basically plugging our open platform across UCaaS and CCaaS into that digital workplace playbook.

So, the first vector of how we expect to do this is through the strategic partnerships. The second thing we are doing is actually going at those specific verticals we want to focus on, and we are basically looking at the critical processes and workflows within these verticals to see where is it that our platform will actually be a core part of all these processes with -- customized to each vertical. So basically that workflow/IP combination and the strategic partnerships which we will double down on, those two come together to allow us to actually create meaningful vertical solutions, which connect to the customers' business and their outcome. So that's the playbook.

Operator

Thank you. Next question is coming from Sterling Auty from JPMorgan. Your line is now live.

Sterling Auty -- JPMorgan -- Analyst

Yeah. Thanks. Hi, guys. So you talked about the timing of the release of the initial ACO product. Just kind of curious what your thoughts are on the initial timing of the migration tools to help customers get up on to ACO?

Vlad Shmunis -- Chief Executive Officer, Founder and Chairman

So I can take that. So, the product launches on March 31st, and right off the back, we will essentially be supporting all of the Avaya end points. And right of the back, we will have the automatic migration capabilities embedded into the product. So there is no lag in timing between product launch and the automatic migration capabilities to take every customer off Avaya on prem to the cloud.

Sterling Auty -- JPMorgan -- Analyst

Got you. And then, one follow up on the Atos partnership. Very familiar through the years, the work that Atos has done especially in Europe around a lot of infrastructure, software, etc, but I'm not as familiar with their UCaaS capabilities. Is this something that they have a broad practice already or are they using RingCentral to kind of launch their present into bringing UCaaS to their customers?

Vlad Shmunis -- Chief Executive Officer, Founder and Chairman

That's a great question actually. So, what we saw as we look to work with Atos is, they have a core -- the core of Atos is transformation is around their digital transmission practice on how they are taking their customers in their journey of transformations to be a digital business. And one of the core elements of what Atos is doubling down on there is essentially the digital workspace because at this point every company looking to digital to transform, the critical success factor of either failure or success is actually culture and how they change the way companies both internally and externally communicate, collaborate and work.

So, essentially our partnership with them is to be this foundation off their digital workplace offerings in their work with their customer's digital transformation. So, that's literally where this whole thing fits in, digital workplace to help Atos digitally transform their customers.

Sterling Auty -- JPMorgan -- Analyst

Got it. Thank you.

Operator

Thank you. Our next question today is coming from George Sutton from Craig-Hallum. Your line is now live.

George Sutton -- Craig-Hallum -- Analyst

Thank you. I was lucky to do a demo of the ACO at the Avaya Engage last week. And it was fairly clear that the collaboration tool would be your blip. It was less clear what the plans were relative to the messaging and also longer term the contact center. So I'm curious if you could provide some clarity there?

Vlad Shmunis -- Chief Executive Officer, Founder and Chairman

Yeah. Vlad here. No, I appreciate the question. Look, we are going to provide additional details on ACO at the time of general availability, which as we indicated is going to be later this quarter. What I can't tell you is that each and every component of ACO, we'll check all of the boxes will be world-class. And we'll address our customers' needs, but as to the specifics if you can just please indulge us for a few more weeks.

George Sutton -- Craig-Hallum -- Analyst

Just a quick follow-up. It looks like there were some IP acquired in the Atos deal. Can you talk about what IP that might be and will that extend into the US as well?

I'll start with the second part. Yes, of course, IP is IP. It's sort of international in nature. There are no limitations associated with that IP. Broadly speaking, it's in the messaging, communications and collaboration space and it includes knowhow, some calls and a fairly sizable patent portfolio, but that's all -- contractually that's all we can share at this point.

George Sutton -- Craig-Hallum -- Analyst

Thank you. Our next question is coming from Nikolay Beliov from Bank of America Merrill Lynch. Your line is now live.

Nikolay Beliov -- Bank of America Merrill Lynch -- Analyst

Hi. Thanks for taking my question. My first question is for Mitesh. Mitesh, looking at the growth in your channel business, growth 63% for two quarters in a row which is pretty good performance and the growth rate in channel seems to be tracking closer again to price growth rate rather than to the -- I mean, market growth rate. Just want to dig into this a little bit and also what are you guys seeing with channel economics? Where do we stand versus, let's say, a year ago?

Mitesh Dhruv -- Chief Financial Officer

Sure, Nikolay. Channel is going to -- has been a key growth driver for us. It's a $300 million business. As you said, growing over 60%. It is now about 35% of the -- our total ARR gained 5 points of share since last year. Channel, we did see record bookings in the channel this quarter, and even in the upmarket side we saw over 70% of our total $1 million dollar deals come from the channel.

And that again dovetailed into -- OK, is it just growth or is it that good growth economics. I think channel is a very profitable business for us. It's more profitable in dollars wise than the direct business, given the higher lifetime value to CAC with the lower upfront investments we have to do and better churn. So, I think the strategic partners going forward will add to the flywheel effect there and help us drive more profitable growth.

Nikolay Beliov -- Bank of America Merrill Lynch -- Analyst

And question for Vlad. Vlad, I want to circle back on the ACO migration, so our conversations with the channel partners both Avaya and RingCentral, the channel guys are really excited about the migration to it. So, if you can maybe help us illustrate, OK, today, an Avaya customer is moving to RingCentral, let's say, an Avaya midmarket customer and it maybe take two to three weeks whatever it is to do the migration, the menu migration and whatnot.

With ACO version 2.0, which is going to launch in May and June when you're going to have the migration tools, what percentage of the migration do you think only get automated? And by how much is going to cut down the migration time? And clearly that has implications on time to revenue and competitive dynamics and all of that, just trying to understand it a little bit better. Thank you.

Vlad Shmunis -- Chief Executive Officer, Founder and Chairman

Sure. Hi, Nikolay. So, look, so firstly thank you for noting and understanding that the MVP that going to go out in, like we said later this quarter, migration tools are really not going to be there. And we have not as of yet committed to a, at least publicly we have not disclosed any specific time frame for migration tools. I can tell you that this is very much front and center for us to get this going once the basic tier boxes are done.

Look, the idea is to simply migration. And at the high level, that means basically being able to import all of the account specific information, whether the IVR trees, company's contacts potential that we can talk about importing even voice mails that were left with on a wire system, etc. So that's the extent, I would expect more of a gradual process. It's going to be sort of a moving train. We'll be introducing these tools over time. But certainly we hope to cover all of the migration cases eventually. So, I would say, over time to the extent possible is 100% just with the caveat that Avaya has multiple user bases internally. And, for example, some of the customers, it may be hard to get the data out just because of the generation of that technology. But for IPO office where there is more modern software involved, we expect to be able to get to the data and to be able to import it into ACO.

Thank you. Our next question is coming from Meta Marshall from Morgan Stanley. Your line is now live.

Meta Marshall -- Morgan Stanley -- Analyst

Great. Thanks. First question, just on the Atos relationship. Any additional investment needed by you guys to launch or will be -- on this kind of co-branded product. Will they be fronting that investment? And then, maybe second question on the contact center business. Just -- I'm seeing that your kind of attach rates are increasing there. Just any color as to whether those are still primarily in contact implementations or whether you're seeing an uptick of the kind of the Connect First homegrown products. Thanks.

Mitesh Dhruv -- Chief Financial Officer

Sure, Meta. Hey, it's Mitesh. I'll take both. The first one on Atos, yes, of course there is investment required to get this up and running. It's all contemplated in the guidance. So, our guidance would have been up even more if there were not these investments. But that said, we do -- given the go-to-market motion there, we do think that this relationship is going to be accretive right from the get go. So that's part one. Part two, on the contact center, right now predominantly it is our in-contact business. Although we are seeing some green shoots with the Dimelo. Anand had call out this Swiss brand with Montblanc. I love those pens by the way. So, yeah -- so we are seeing green shoots there, but early days for that.

Meta Marshall -- Morgan Stanley -- Analyst

Got it. Thanks, guys. Congrats.

Thank you. [Operator Instructions] Our next question is coming from Michael Turrin from Wells Fargo. Your line is now live.

Michael Turrin -- Wells Fargo Securities -- Analyst

Hey, there. Thanks. Good afternoon. Mitesh, we've seen a bias on UCaaS toward customers paying on a monthly basis. Just wondering if you could provide some color around your expectations given that backdrop for the shape and variability deferred revenue on the model here?

Mitesh Dhruv -- Chief Financial Officer

Yeah. Sure. Thanks, Michael, and welcome -- welcome to rejoined RingCentral earnings call. So, thank you for -- again taking up coverage. So, in terms of deferred revenue, yes, deferred revenue is a function of more the payments that customers have and not quite a function of the length of the contract. So, on the prepayment, what we are seeing here is two trends. We are seeing a normalization of our customers paying us on annual prepays. Which is actually helping us give less discounts up front, that's one. And products like contact center are typically building arrears. So that actually has a impact on deferred revenue. But on the length of the contracts customers are signing up for multiyear contracts with RingCentral given the more comfort level they have with us. And so, if you want to take up duration impact from this overall equation, I think ARR abstracts this noise. And it levels the playing field in terms of forward-looking indicator. So, I think, for our business and quite frankly businesses which have more bias toward monthly payments. I think that would steer our investors to look at ARR growth.

Thank you. Our next question today is coming from Nandan Amladi from Guggenheim Partners. Your line is now live.

Nandan Amladi -- Guggenheim Partners -- Analyst

Thank you. Good afternoon. So, now that you've passed the $1 billion run rate, you're ahead of schedule. Have you thought about updating your long-term model?

Mitesh Dhruv -- Chief Financial Officer

Sure. Sure, Nandan. We have thought about it. We -- first of all, thank you for noticing that. Yes, we did clear this $1 billion hurdle ahead of schedule. And the goal is, again, to look -- keep on layering on more investments in both product and go-to-market. To put a new long-term target out, it makes sense for us to gauge how all these initiatives are panning out, AT&T bit, Avaya bit, Atos and then provide a very thoughtful long-term model over time.

Operator

Thank you. Our next question today is coming from Will Power from Robert W. Baird. Your line is now live.

Will Power -- Robert W. Baird -- Analyst

Okay, great. Thanks. Yeah. I guess I just wanted to come back to Atos. It sounds like this could be the first and maybe some additional strategic opportunities. So, I guess, I wonder, A, how many more deals like this potentially out there are there either in Europe or the US? How should we think about that? And as part of that, is there any way to kind of help us frame how to think about the ultimate size of this? And they are now expecting much revenue contribution this year but is this something that you expect to contribute maybe $50 million of revenue a few years out? Could it be somewhat similar to AT&T over time? How do we kind of think about that? Thanks.

Mitesh Dhruv -- Chief Financial Officer

Yeah. Hey, Will. I think -- it's again, look, we just think the deal last quarter, so early days. But if you look at the overall potential, Atos is a number one digital transformation player in Europe with deep transformation projects across the board. And I think there's an opportunity for us to have a place where communication becomes a hub with all these major cloud transformation projects they have, A. Part B, they also work with G Suite, Microsoft, ServiceNow, Salesforce, all of these which are key integrations for us. So there is a real avenue where we are dragged along with this end-to-end projects. Now, in terms of what revenue opportunities there could be, it could be meaningful but again it's very hard to tell at this stage, given we just inked the deal. So stay tuned.

Thank you. Our next question is coming from Samad Samana from Jefferies. Your line is now live.

Samad Samana -- Jefferies -- Analyst

Hi. Good evening. Thanks for taking my question. So, Mitesh, just for clarity, the 25% to 26% growth outlook for 2020, does that include the Avaya later in the year that you mentioned? And then, maybe just International, how did performance go there? We haven't heard much about that and maybe just how large deal performance was outside of the US? Thanks again for taking my questions, and congrats on an awesome quarter.

Mitesh Dhruv -- Chief Financial Officer

Samad, you were supposed to ask one question; you jammed in four. But it's OK. So, first of all, on the guidance, it does assume some minimal contribution from Avaya in the guidance but not material, at least because we are getting started. That's part one. In your -- what's the second part of the question, internationally, you said?

Samad Samana -- Jefferies -- Analyst

[Indecipherable]

Mitesh Dhruv -- Chief Financial Officer

Yeah. So international -- yeah, we saw -- international is about, call it, 10%-ish of our revenue. And it is growing very nicely above the overall growth of the business. We feel that Atos and Avaya will be vectors for ramping up international growth for us going forward as both of these companies have significant investment presence.

Thank you. Our next question is coming from Rich Valera from Needham. Your line is now live.

Richard Valera -- Needham & Co. -- Analyst

Thank you. Let me add my congratulations on a nice finish to the year, gentlemen. Follow-up on the contact center discussion before, clearly you've had great success in selling a tightly integrated contact center with your UC product. Do you want to think about -- how you're thinking about ACO. You're going to have essentially a UC private -- UC cloud product, Avaya is going to have a cloud contact center product presumably about the third quarter of this year. So, how do you think about sort of a long-term trajectory of ACO with a cloud contact center and how critical that is to making this ultimately successful?

Mitesh Dhruv -- Chief Financial Officer

Yeah. That's a good question. So, what I would say is, it's always beneficial for RingCentral when customers decide to move different applications and especially in the case of contact center to the cloud. We'll be able to better gauge at least as it relates to Avaya's CCaaS product. We'd be able to better gauge the impact of that once it is on the market. It's hard to actually say anything to it right now.

James Fish -- Piper Sandler -- Analyst

Hey, guys. You've done a fantastic quarter and end of the year, and congrats, Anand, on the new role here. Just I'll squeeze one in for you. Can you just walk us through exactly what sales and marketing changes were made to make -- by a partnership ready to go already? And I guess, any sense of how channel partners can get compensated compared to the traditional go-to-market? Thanks.

Vlad Shmunis -- Chief Executive Officer, Founder and Chairman

Sure. In terms of the -- can you repeat the second part of the question, didn't come through the clearly?

James Fish -- Piper Sandler -- Analyst

How the channel partners are going to be compensated compared to your traditional approach?

Vlad Shmunis -- Chief Executive Officer, Founder and Chairman

Sure. So, on the second one, there's going to be no difference in the channel compensation. They are going to be compensated the way they have been getting compensated. In terms of our go-to-market changes, it's more train, to train our model where we have our product and our overlay team -- the channel overlay team. That channel overlay team will be responsible or has been training the AV Avaya salespeople and the Avaya channel. So that's the motion where we have been -- we will be able to leverage their vast go-to-market capabilities.

Andrew King -- Dougherty & Company -- Analyst

Hey, there. Andrew King on for Catharine Trebnick. Thanks for taking my question. So, on a revised earnings call this morning, they mentioned that originally ACO would only be released in the US. I want to hear a little bit more color into what the next region they'd be launching into and what that timeline would look like? Thanks.

Vlad Shmunis -- Chief Executive Officer, Founder and Chairman

Sure, Andrew. So, for this year, there's a plan to roll out US initially and a couple of countries internationally, which I would say, if you get it all out, we'll be able to cover at least 60% to 70% of all the geo regions where the Avaya's presence is with ACO product.
