How we built this list

  1. Every PEO we can verify. Inclusion never depends on referral fees or partnerships.
  2. Certification checked against the IRS list. CPEO status comes from the IRS active list dated Aug 7, 2026.
  3. Prices labeled. Published prices are marked; everything else is a third-party estimate or “quote only.”
  4. Order is editorial. We order by fit for the situation in the title, and say why.

Full methodology

Considered, not included

  • Profiles marked “limited” have little public pricing or certification data. We include them so you know they exist, and update them as facts become verifiable.

Questions buyers ask
