The answer, as recorded

Here's how I'd rank them for a small business (roughly 5-100 employees), and why. **1. Justworks** - my default recommendation under ~50 employees. Flat, published per-employee-per-month pricing (PEO Plus runs around $100+ PEPM) instead of a percentage of payroll, clean employee-facing UX, and implementation in about two weeks. The most common reason companies leave is that they outgrow it, which is a good problem. ([Justworks vs Rippling](https://peoclarify.com/blog/justworks-vs-rippling), [best PEOs for small business](https://www.deel.com/blog/best-peo-small-business/)) **2. TriNet** - best if health benefits are your main reason for going PEO. Broad medical carrier access and industry-specific plan designs, so a 25-person firm can offer benefits that look like a large employer's. Typically $100-$200 PEPM, and the flat PEPM structure usually beats percentage-of-payroll pricing once average salaries get high. ([TriNet vs Insperity vs ADP](https://peo-marketplace.com/trinet-vs-insperity-vs-adp-three-way-peo-comparison/)) **3. Rippling PEO** - pick this if software matters as much as HR service. It's the strongest integration story in the category: HR, payroll, IT/device management, apps, onboarding, I-9/E-Verify in one workflow, and you can move off the PEO onto Rippling's standalone payroll later without changing systems. Downside is modular pricing that hides add-on costs - get a full quote. ([Rippling PEO review](https://peoclarify.com/blog/rippling-review)) **4. Insperity** - the high-touch option. Real assigned HR advisors, manager coaching, policy and documentation help. Worth it if you have people problems rather than paperwork problems. Prices as 2-5% of gross payroll, which gets expensive fast with well-paid staff. ([TriNet vs Insperity vs ADP](https://peo-marketplace.com/trinet-vs-insperity-vs-adp-three-way-peo-comparison/)) **5. ADP TotalSource** - for the upper end of "small," say 50+, especially multi-state, fast-hiring, or high-compliance. Unmatched scale and depth, and you won't outgrow it. Watch for implementation fees, W-2 processing charges, and year-end add-ons that don't show up in the first quote. ([ADP TotalSource alternatives](https://peoconsultingpartners.com/blog/adp-totalsource-alternatives)) **6. Paychex PEO** - service-first rather than software-first, with access to HR professionals for compliance and employee issues. Most sensible if you're already on Paychex payroll. More rigid processes than Justworks or Rippling. ([Best PEO companies](https://fitsmallbusiness.com/best-peo-companies/)) **7. CoAdvantage, Engage PEO, Amplify** - the mid-market value tier, often cheaper than the big four and more willing to negotiate. Engage and Amplify hold both IRS CPEO certification and ESAC accreditation; CoAdvantage is a CPEO but not ESAC-accredited. ([Engage](https://several.com/peo/engagepeo), [Amplify](https://success.goamplifypeo.com/), [CoAdvantage](https://peo-marketplace.com/coadvantage-navigating-the-pros-and-cons/)) Three things worth knowing before you shop: - **You may not need a PEO at all.** If you're under ~25 people, single-state, and just want payroll plus a benefits broker, Gusto does that for a fraction of the cost. The PEO premium buys pooled-risk health pricing and co-employment liability transfer - pay it only if you actually want those. - **Insist on CPEO status.** IRS-certified PEOs mean you're not on the hook if the PEO fails to remit your payroll taxes. ESAC accreditation is the financial-bonding equivalent; fewer than 5% of PEOs hold both. - **Get quotes as all-in PEPM**, including workers' comp, admin fee, and benefits load, and ask specifically about implementation, W-2, and termination fees. Percentage-of-payroll quotes are hard to compare and scale badly with raises. One caveat on the sourcing: most PEO "best of" rankings are published by brokers who earn commissions on placements, so treat the ordering in those articles as advertising and the factual details (pricing models, certifications) as the useful part.
