The short answer

  • Justworks : PEO with printed $79 and $124 per-employee plans. From $8/employee/mo
  • Gusto : Self-serve US payroll and benefits without co-employment. From $49/mo
  • ADP Workforce Now : Mid-market HCM if you will not join a PEO. From Sales-quoted

Why people look past TriNet

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

What we noted

  • No public per-employee rate
  • Quote depends on state mix
  • Not a global EOR platform

Not the right fit for

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

Worth keeping in mind: Full PEO plus an HR Plus platform-and-support line for companies that are not ready for co-employment.

What each one does differently

Justworks

$8/employee/mo

Why it comes up: PEO with printed $79 and $124 per-employee plans.

Stands out: A cheap payroll SKU plus two PEO tiers, so you can stay payroll-only or move into benefits later.

Watch out: Payroll-only adds a $50 monthly base fee. PEO Plus is the benefits tier at $124 per employee. EOR is $599 per employee.

Best for

  • US startups that want a printed payroll rate
  • Teams ready for PEO benefits at $79 or $124
  • Employers that also need time tracking access

Gusto

$49/mo MCP API

Why it comes up: Self-serve US payroll and benefits without co-employment.

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.

Best for

  • US small companies running payroll in-house
  • HR teams that want benefits next to pay
  • Desks that want MCP on payroll data

ADP Workforce Now

Sales-quoted

Why it comes up: Mid-market HCM if you will not join a PEO.

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.

Best for

  • US mid-market employers consolidating payroll and HR
  • Teams that already bank with ADP payroll tax filing
  • HR leaders who want time and benefits in the same suite

Paychex

Sales-quoted API

Why it comes up: Payroll and HR outsourcing with a similar quote motion.

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
