Paychex
Sales-quoted API
Why it comes up: Parent company's own payroll and HR line if you want Flex instead of Paycor.
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.
Best for
- US small and midsize businesses that want payroll plus HR help
- Firms considering a PEO from the same vendor
- Accountants managing client payroll
