Buyers Guide

Last Updated: March 16, 2023

As a professional employer organization (PEO), HR isn't just an important facet of your business; it's your business, period. Client companies rely on you to handle all of their important employee management needs, and if you can't deliver a stress-free experience, they'll go to your competitor or hire staff to do their HR in-house.

You need to be able to execute efficiently on important HR tasks and keep clients happy at the same time. In other words, you need software. But maybe you're not sure what options are out there, or which system will best fit your needs.

We're here to help.

In this Buyer's Guide, we'll go over everything you need to know about PEO software to help you make a more informed purchase decision.

Here's what we'll cover:

What Is PEO Software?

Common PEO Software Features

How Much Does PEO Software Cost?

Key Considerations When Purchasing PEO Software

Additional PEO Software Resources

What Is PEO Software?

PEO software helps PEOs and administrative services organizations (ASOs) perform HR duties for client businesses. Along with functionality to manage your customers' core HR needs—things like payroll, benefits enrollment and compliance reporting, for example—PEO software systems also allow you to create custom invoices and bill clients for services rendered.


PEO dashboard in Worklio

Being a PEO doesn't necessarily mean you need to buy a product solely dedicated to the PEO/ASO audience, though they do exist (e.g., PrismHR). Many popular HR systems offer the functionality PEOs need and cater to both in-house HR departments and outsourced HR service providers (e.g., Paylocity).

Common PEO Software Features

PEOs need to make sure that any software they adopt has the functionality to support the services they offer. Here are some common features buyers should look out for when evaluating different PEO software systems:


Manage wage and salary rates for employees. Automatically calculate and run payroll, pay workers, run reports and export payroll costs to the company accounting ledger.

Benefits administration

Allow workers to enroll in benefits plans or change options on existing enrollments themselves. Run reports and track program costs.

Time and attendance

Monitor employee paid time off and hours worked. Automatically port hours into payroll to calculate accurate compensation.

Applicant tracking

Post job openings, create candidate profiles and manage applicants through client hiring workflows.


Automatically walk new hires through client onboarding processes. Important paperwork can be signed and stored digitally.

Compliance management

Track client compliance with local, state and federal employment laws (e.g., ACA, EEOC, OSHA etc.).

Billing and invoicing

Correctly bill clients for services offered. Send customizable invoices and track accounts receivable.

Client and employee portals

Gives workers and HR personnel access within the system to view information and perform tasks such as running reports.

Some PEOs may elect to buy separate HR systems with all the functionality they need and integrate them together, but we recommend investing in one comprehensive solution, if possible.

A comprehensive solution mitigates the risk of data becoming lost or corrupted while transferring between applications, and provides a better experience for clients, who only have to learn and log in to one system.

How Much Does PEO Software Cost?

It would be great if all PEO software systems were priced the same way, but unfortunately that's not the case. Here are some common pricing structures you can expect to run into:

  • Perpetual license. This is more common with on-premise systems that are hosted on your own server (as opposed to cloud-based software, which is hosted by the vendor and accessed through a web browser). You pay one large upfront cost to own the software indefinitely.

  • Subscription (per employee, per month or per user, per month). Vendors may charge based on the number of employees in your organization or the number of employees total across all of your clients, so be sure to ask what they mean by "per employee."

  • Freemium. Some vendors offer a basic version of their platform for free, then charge for extra functionality. Open source software is also "free" in the sense that it doesn't cost any money to get access to the code, but there is still a significant investment here in terms of IT deployment and maintenance.

Key Considerations When Purchasing PEO Software

Before you talk to a single PEO software vendor, you first have to ask important questions internally about your goals and constraints.

These include: Which features do you need and which ones do you merely want? What's your budget? If you're replacing an existing system, what have been the most significant pain points you want to remedy? What's your deadline to be up-and-running with new software?

Once you have answers to these important questions and pare down your options, it's time to do demos. Here are some key considerations to keep in mind when evaluating different PEO software systems:

  • User interface is critical. With an in-house system, you might be able to get away with a clunky interface, if it gets the job done. Not so if you're a PEO. Clients are going to be using your system too, so it's vital that whatever software you choose be intuitive and easy to use.

  • Will your software play nice with client systems? Clients may have their own accounting or time tracking systems they want to use. If they can't easily integrate with your software, that will lead to headaches down the road.

  • Evaluate the support behind the software too. Talk to vendors extensively about the support options they offer and their associated cost. Also be sure to understand how they will handle updates. The last thing you need is a client being unexpectedly locked out of the system during maintenance.

Additional PEO Software Resources

A PEO software purchase isn't something that should be taken lightly. Whatever product you choose will have a profound effect on the quality of service you offer.
