Professional employer organizations, or PEOs, are HR companies that handle other business’s complex HR needs. If your business partners with a PEO company, the PEO will take everything employee-related off your hands, from hiring and onboarding to payroll, benefits and taxes.

PEOs are typically more expensive than in-house HR and payroll software solutions. Additionally, PEOs must become legal co-employers with your business so they can file payroll taxes on your behalf. As long as you have the budget for it and are fine sharing ownership of your company with a third party, working with a PEO can give you time to focus on running your business instead of dealing with HR.

The best PEO solution for most small and midsize businesses is ADP TotalSource. But if ADP TotalSource isn’t a good fit for you, there are plenty of other PEO companies that can take HR and payroll off your hands entirely.

How to choose the right PEO company

There is no one-size fits all solution when choosing a PEO company. While some PEO technology may sound attractive for small companies, big enterprises with large workforces may require other features.

Several factors need to be considered before purchasing a PEO: Before contracting with a PEO company, consider factors like budget, number of employees, benefits that your organization offers, where you operate, what type of automation you require, what work culture you are building and how complex your compliance situation is. It’s also important to discuss HR, IT, payroll, accounting and finance tools with your respective teams to know which HR and payroll software platform they are more comfortable with and gain better insight into what your talent needs.

Frequently asked questions

What is a PEO?

A PEO, or professional employer organization, is a payroll and HR solution for small businesses that want to outsource those services instead of handling them in house. A PEO will become your business’s legal co-owner in order to legally hire employers on your behalf, process payroll, pay your employees and sign them up for benefits.

Why should you use a PEO?

Small businesses that don’t have time to spend on payroll, HR and legal compliance may benefit from turning those tasks over to a PEO company that specializes in human resources.  With the help of a PEO service provider, business owners can focus on expanding operations and making sure their business is running smoothly. Meanwhile, HR professionals can handle every element of the employee life cycle to ensure employees have a positive experience working for your company.

What’s the difference between a PEO and a payroll service?

A payroll software service is a typically cloud-based payroll solution that enables employers to run payroll, pay employees and administer employee benefits in house. In contrast, a PEO is an outsourced solution where a PEO company takes HR and payroll tasks off a business’s plate so the business owners can focus on daily business tasks rather than focusing on the ins and outs of complicated payroll tax laws.
