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

Paycom

Stands out: Every tool runs on one employee database, and the Beti feature has employees check and approve their own payroll before it runs.

Watch out: There is no public price. The quote depends on headcount and which tools you add to the required Core package.

Not the right fit for

  • Buyers who need a published per-employee price
  • Very small teams that want low-cost self-serve payroll
