The short version

  • Each has a real cost: ADP no pricing is published; every quote is custom and driven by employee count and which services are taken; Justworks the published per-employee fee is the platform charge, not your cost; health insurance premiums and workers' compensation are billed on top and are usually several times larger, so the transparent price is transparent about the smaller number.
  • They diverge on capability: ADP covers Payroll, Justworks covers Co-employment PEO.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

ADP

  • No pricing is published; every quote is custom and driven by employee count and which services are taken
  • Split into three separate products by company size, RUN for 1 to 49 employees, Workforce Now for 50 and above, and Lyric HCM for enterprise, so growing across a threshold means changing product rather than plan

Justworks

  • The published per-employee fee is the platform charge, not your cost; health insurance premiums and workers' compensation are billed on top and are usually several times larger, so the transparent price is transparent about the smaller number.
  • Leaving a PEO is a project, not a cancellation: you must source your own health plan, obtain your own state employer registrations and unemployment accounts, and time the switch to a plan year, which typically takes months.
  • Coverage is United States only, so the moment you hire your first employee in another country you are running a second system and Justworks handles them only as a contractor.
  • PEO Basic looks like a cheaper way in but excludes the Justworks health plans, which is the main reason companies choose a PEO at all, so most buyers end up on Plus.
  • Benefit plan choice is constrained to what Justworks has negotiated, and a company with strong preferences about carriers or network coverage in a specific region may find the options do not fit.

Justworks: What does co-employment actually mean?

Justworks becomes the employer of record for payroll tax and benefits purposes while you retain full control over hiring, management and day-to-day work. It is a legal arrangement, not an outsourcing of your team.

ADP: Is there a current promotional offer for ADP payroll?

ADP currently offers 3 months free when signing up for small business payroll (promotion ends 9/24). Contact sales at 800-225-5237 for details and to request pricing based on your employee count.

Justworks: Is the $79 figure my total monthly cost per employee?

No. It is the platform fee. Health insurance premiums, dental, vision and workers' compensation are additional and typically dwarf it.

Justworks: Can Justworks employ people outside the US?

No. It can pay international contractors, but it is not an employer of record abroad.

Justworks: What is the difference between the Payroll plan and the PEO?

The Payroll plan handles payroll and benefits administration under your own EIN at $8 per employee per month plus a base fee. The PEO adds co-employment and pooled large-group insurance at $79 or $109.
