Provider register
Each entry reports what two public registers say — the federal certified professional employer organization listing and the independent accreditation directory — plus the fee structure the provider states publicly. No rate is quoted, no provider is ranked, and nobody pays to appear.
| Provider | Federal certification | Accreditation | Fee structure |
|---|---|---|---|
| TriNet | Certified (listed by the IRS) | Accredited | Bundled service fee, quoted per employee per month or as a share of payroll depending on plan |
| Insperity | Certified (listed by the IRS) | Accredited | Administrative fee quoted as a share of gross payroll under the full-service Workforce Optimization offer |
| ADP TotalSource | Certified (listed by the IRS) | Accredited | Per employee per month service fee, bundled with the ADP payroll platform |
| Gusto | Not listed on the IRS certified PEO public listing | Not listed in the ESAC directory | Software subscription: a base monthly fee plus a per-person monthly fee |
