Where they pull apart

Paychex

Stands out: A payroll specialist with HR advisers, 401(k), insurance and PEO options, and a public developer portal for integrations.

Watch out: There is no public per-employee price for Flex. SurePayroll, a Paychex company for very small businesses, is a separate product.

Not the right fit for

  • Buyers who need a published self-serve price
  • Teams that want only a simple low-cost payroll app

PrismHR

Stands out: A platform that PEOs and payroll bureaus run their own client service on, from hire to retire.

Watch out: PrismHR sells mainly to PEOs and payroll service providers, not direct to small employers. Pricing and implementation are quoted.

Not the right fit for

  • Small employers buying payroll direct
  • Global employer-of-record buyers
