4. ADP mentioned
   ADP TotalSource - The pick if you want Fortune-500-grade benefits and a vendor that will still be there in 15 years, and if you expect to grow past PEO size eventually (migrating to ADP's non-PEO payroll products is a well-worn path).

The answer, as recorded

## Who I'd actually look at, in order **1. Justworks** - My default recommendation for a small business under ~50 employees. It's the only major PEO with published, flat per-employee pricing (roughly $79/employee/month for the basic PEO tier, ~$109-$124 for the tier with better benefits options - sources disagree slightly, so get a live quote). Clean software, good support reputation, and you get access to their large-group health plans without building an HR function. The tradeoff: it's US-only and the HR support is lighter-touch than the big players. [justworks.com pricing comparison](https://www.justworks.com/compare/justworks-vs-trinet) · [gloroots.com/blog/justworks-pricing](https://www.gloroots.com/blog/justworks-pricing) **2. TriNet** - Where I'd go if benefits quality is the main reason you're buying, or if you're in a regulated or specialized industry (financial services, life sciences, nonprofits) where you want vertical-specific compliance expertise baked in. Strongest benefits menu of the group. Quote-based pricing, usually a percentage of payroll, which gets expensive as salaries rise. [fitsmallbusiness.com/best-peo-companies](https://fitsmallbusiness.com/best-peo-companies/) · [trustradius.com TriNet vs Insperity](https://www.trustradius.com/compare-products/trinet-vs-insperity) **3. ADP TotalSource** - The pick if you want Fortune-500-grade benefits and a vendor that will still be there in 15 years, and if you expect to grow past PEO size eventually (migrating to ADP's non-PEO payroll products is a well-worn path). Bigger, more bureaucratic, less nimble than Justworks. [fitsmallbusiness.com/best-peo-companies](https://fitsmallbusiness.com/best-peo-companies/) **4. Insperity** - Best if what you actually want is a human HR consultant, not software. High-touch service model with real training and management-coaching resources. Generally the priciest of the four, and overkill if you just need payroll plus health insurance. [justworks.com/compare/justworks-vs-insperity](https://www.justworks.com/compare/justworks-vs-insperity) **5. Paychex PEO** - Worth a quote if you're already a Paychex payroll customer, or if you're very small (under ~10 people) where the big PEOs lose interest. Solid, unexciting. **6. Rippling PEO** - Choose this one if the *software* is the point. It's an HRIS/IT/finance platform first with PEO bolted on, so you get device management, app provisioning, and deep automation alongside payroll. Modular pricing starts cheap and climbs fast as you add modules. Also the better answer if you have any international headcount. [rippling.com Rippling vs Justworks](https://www.rippling.com/blog/rippling-vs-justworks-hr-payroll-peo-comparison) **7. ExtensisHR / CoAdvantage / Engage PEO** - Regional and mid-market specialists. I'd only pull these into a bid if the big four come back with bad benefits rates for your state or industry; they sometimes win on price and account-manager attentiveness. [resources.rework.com best PEO services 2026](https://resources.rework.com/tools/payroll/best-peo-services-2026) ## Two things that will save you money Get quotes from at least three, and insist they break out **administrative fee vs. benefits cost separately**. PEOs quote bundled percentages of payroll specifically to make comparison hard. Also ask whether the admin fee is flat PEPM or a percentage - percentage pricing quietly punishes you every time you give raises. And a caveat on the rankings above: most "best PEO" listicles, including several in my sources, run affiliate programs with the vendors they rank. Treat the ordering as a starting shortlist, not evidence.
