Where they pull apart

Gusto

Stands out: Payroll sitting next to HR for US small companies, with a first-party MCP.

Watch out: It is US-only, so it is not a route to hiring people in other countries.

Not the right fit for

  • Global employer-of-record buyers
  • Enterprise HRIS selection processes

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
