Where they pull apart

ADP Workforce Now

Stands out: One ADP suite for payroll, talent, time, and benefits aimed at companies that have outgrown starter payroll.

Watch out: There is no public per-employee menu. Implementation and modules are scoped in a sales cycle.

Not the right fit for

Five-person shops that want a published $29 payroll plan
Buyers who need same-day self-serve checkout

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
