To determine the best PEOs, we started with a pool that included all of the vendors on the list below. After some preliminary research, including looking at other best-picks lists and doing initial research on each, we interviewed small business owners to discover new ones to add to our list.

Ultimately, we settled on 14 PEOs to research as best picks: ADP, Ahead Human Resources, Alcott HR, Algentis, Best Employment Solutions Team, CoAdvantage, Employer Solutions Group, FrankCrum, Insperity, Oasis Outsourcing, Paychex, Premier Employer Services, TriNet and XcelHR. (See the full list of PEOs and their websites below.)

Next, we researched each provider by investigating its services, considering its pricing structure, watching videos on employee access platforms, and reading customer reviews and complaints. After narrowing down the list to eight final contenders, we contacted each company by phone and posed as new business owners in order to gauge the type of support each provider offered.

Our process involves putting ourselves in the mindset of a small business owner and gathering the data that would be readily available to such an individual. We perform all of our research by visiting company websites, making calls to customer service and interviewing real users.

In all, we analyzed each service based on the following factors:

  • Payroll services
  • Benefit options
  • HR guidance and support
  • Additional services
  • Pricing structure
  • Online employee access
  • Mobile access
  • Customer service
  • Accreditations
  • Size of companies serviced
  • States served
