RUN Powered by ADP and Paychex Flex both offer a long list of features and add-on options to their customers. But what differentiates the two applications? Read on to find out.


RUN Powered by ADP vs. Paychex Flex: An overview

RUN Powered by ADP and Paychex Flex are two of the oldest payroll services companies in the U.S. Both have a history of providing not only payroll processing, but related services such as human resources (HR) and employee benefits administration.

But which one is best for your small business?

In all honesty, you won’t go wrong with either application, but as we compare these two industry leaders side-by-side, you may find exactly what you’re looking for in a payroll software.

Who is RUN Powered by ADP for?

RUN Powered by ADP is an online payroll application that can be conveniently used with a desktop, laptop, smartphone, or tablet.

Designed for anytime/anywhere access, RUN Powered by ADP is geared toward small businesses with 49 employees or less. For larger businesses, ADP Payroll offers several other options.

RUN Powered by ADP offers four plans:

  • Essential Payroll
  • Enhanced Payroll
  • Complete Payroll (Payroll & HR)
  • HR Pro

Very small businesses can start with the Essential plan and move up to a more robust plan as needed.

RUN Powered by ADP uses wizards throughout the application, and years of payroll experience have helped its developers create an intuitive user interface that works well even for those who are still trying to learn how payroll works.

RUN Powered by ADP does offer a mobile app, but it’s considered an add-on, so you’ll pay extra for it.

Who is Paychex Flex for?

Paychex Flex is also designed for businesses with 49 employees or less. Scalable, Paychex Flex, like RUN Powered by ADP offers four plans to choose from:

  • Express Payroll
  • Select Payroll
  • Pro Payroll
  • Enterprise Payroll

The Express plan in particular is an excellent option if you only need to pay a few employees, though you’ll want to move up to Paychex Flex Select should you add staff. Conversely, you can also downgrade your plan should your employee numbers drop.

In addition, Paychex Flex offers a free mobile app that works with both iOS and Android devices, allowing you to easily process payroll right from your phone.


RUN Powered by ADP vs. Paychex Flex: Features

Both RUN Powered by ADP and Paychex Flex offer many of the same features that small businesses need. Here’s a breakdown of what each offers.

What RUN Powered by ADP offers

RUN Powered by ADP offers the following features in all of their plans:

  • Calculation, remittance, and filing for federal, state, and local payroll taxes
  • Computer, mobile app, or telephone payroll processing
  • Direct deposit
  • Payroll delivery
  • Reporting
  • G/L interface
  • New hire reporting
  • Employee onboarding

State Unemployment Insurance (SUI) processing is not available in the Essential plan, but is available in the other three plans.

In addition, if you’re looking for comprehensive HR features such as the HR Help Desk, Employee Handbook, or access to various HR forms and documents, you’ll have to opt for one of the top two plans.

You can pay employees in all 50 states, but if you process payroll for more than one state, you’ll pay extra. You’ll also pay extra for the mobile app.

There are also add-on options for employee insurance and retirement administration, and if a feature is not included in a plan, it can usually be added at an additional cost.

What Paychex Flex offers

Paychex Flex features vary, depending on the plan purchased.

While all plans include complete payroll tax administration, new hire reporting, and a free mobile app, additional features such as a G/L link to popular accounting software, a workers’ compensation report, state unemployment insurance, and additional pay options are only available in the more expensive plans.

Paychex Flex offers payroll services in all 50 states, and employee self-service is available in the application as well.

In addition, Paychex Flex offers employee onboarding in its two higher priced plans, with a scaled down version available in the other plans.

You do have the option to add these services to your less expensive plan, which of course will raise the price. Paychex Flex also processes both W-2s and 1099s, again for an additional fee.

Other Paychex Flex features available include:

  • 24/7 phone and chat support
  • Paycards
  • Automated employment and income verification

Results

Winner: RUN Powered by ADP

Though close, RUN Powered by ADP is the winner. While many of the features are the same in both applications, RUN Powered by ADP includes more of these features in their less expensive plans.


RUN Powered by ADP vs. Paychex Flex: Support

Support isn’t usually the first (or second) thing you think about when purchasing software, but when things aren’t going right, and your payroll isn’t processing properly, you’ll want to be able to access support quickly.

What RUN Powered by ADP offers

RUN Powered by ADP offers both employee and payroll administrator support, with separate options available for both.

While employee support is limited to general questions, payroll administrators will be able to access various support options using the password provided once your subscription has been processed.

What Paychex Flex offers

Paychex Flex offers easy access to help and support features from within the application, or you can choose to access support directly from the support page by logging in.

Paychex customer service options are also available from your local Paychex office.

In addition, those subscribing to the Select, Pro, or Enterprise plans are assigned a dedicated payroll specialist that serves as your point person for any questions or concerns you may have.

Results

Winner: Paychex Flex

While both applications offer good support options, I’d have to give the edge to Paychex Flex, as they offer 24/7 support along with local support options.


RUN Powered by ADP vs. Paychex Flex: Ease of use

When looking for software, one of the most important considerations is ease of use. After all, an application can be loaded with features, but if they’re difficult to access, it’s likely they’ll never get used.

What RUN Powered by ADP offers

RUN Powered by ADP offers an intuitive user interface, with an easy-to-navigate dashboard featuring icons that provide quick access to payroll and related features. A series of graphs below the icon area display payroll totals, your current bank balance, and a to-do list.

Another plus; RUN Powered by ADP uses wizards throughout the application, including the Company Setup Wizard for creating your company, and the New Hire Wizard, which makes it easy to add new employees or contract workers.

What Paychex Flex offers

An implementation specialist handles all setup in Paychex Flex, which is usually completed within 48 hours. The implementation specialist will also assist with your first few payroll runs to ensure that everything is working properly.

Once this process is complete, you can begin to process payroll, submitting information online, or by calling or emailing employee hours to Paychex Flex.

Paychex Flex offers an easily navigated dashboard display, where you can access application features from the vertical menu to the left of the screen. The dashboard display is completely customizable, so you can display only the information that you wish.

Payroll information can be reviewed and edited before processing, with a variety of payroll reports available, such as a payroll register or tax liability report, which can be set up to print automatically after each payroll.

Results

Winner: RUN Powered by ADP

It’s great that Paychex Flex offers product setup, but when it comes to overall ease of use, RUN Powered by ADP wins this one by a nose.

Though both offer user-friendly navigation and easy access to all payroll features, RUN Powered by ADP offers a simpler interface that is less intimidating to new users.


RUN Powered by ADP vs. Paychex Flex: Pricing

Both RUN Powered by ADP and Paychex Flex are less than open about their pricing, using per feature pricing rather than an all-in-one price.

ADP vs Paychex showing RUN Powered by ADP pricing chart

ADP offers a variety of plans you can choose from.

A typical monthly subscription for 10 employees will run about $150 to $180 per month. However, since you can add additional features to any core plan, the pricing can fluctuate tremendously.

ADP also runs numerous specials and typically offers introductory pricing to new businesses, so in order to get a more accurate quote, it’s best to speak with a company representative. Be warned that it’s very difficult to get a price quote from them prior to signing up for their service.

What Paychex Flex offers

Like RUN Powered by ADP, Paychex Flex is reluctant to publicly share pricing for their payroll services, so if you’re interested, you’ll have to contact the company directly to obtain a quote.

Pricing has been estimated at around $3,000 annually, though you’ll have to pay extra for things like a setup fee, as well as year-end form processing such as W-2s and 1099s.

Paychex Flex currently offers four payroll plans, which include the following:

  • Express Payroll: designed for very small businesses and startups
  • Paychex Flex Select: the most popular plan for small businesses
  • Paychex Flex Pro: ideal for growing businesses
  • Paychex Flex Enterprise: best for larger businesses with more complex needs
