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, and API and MCP access need the separately billed API Central add on.

Not the right fit for

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

TriNet

Stands out: Full PEO plus an HR Plus platform-and-support line for companies that are not ready for co-employment.

Watch out: Price depends on state mix and headcount. There is no public per-employee rate card.

Not the right fit for

  • Buyers who need a printed $ per employee
  • Global EOR needs outside the US PEO model
