# Best PEOs for Small Businesses Here's who I'd actually point you to, roughly in the order I'd evaluate them: **1. Justworks** - My default recommendation for most small businesses under ~100 employees. It's the only major PEO that publishes real pricing: **PEO Basic at $79/employee/month and PEO Plus at $109** (some sources now list Plus at $124). It's IRS-certified (CPEO), takes companies with as few as two W-2 employees, and consistently wins on ease of setup and support quality. If you don't want to sit through three sales calls just to learn what something costs, start here. **2. Rippling PEO** - The pick if you care about software more than hand-holding. It unifies HR, IT (device/app provisioning), payroll, and finance in a way no other PEO does, starting around **$85/employee/month** on top of its $8/employee HR base. Best for tech-forward teams that are hiring fast. The flip side: you're buying a platform, not a dedicated HR person. **3. TriNet** - Worth a look if you're in a specialized vertical (life sciences, financial services, nonprofits, tech). TriNet builds industry-specific benefit and risk packages and scales from ~5 to 1,000+ employees, with deeper reporting across payroll, benefits, and workforce trends. Pricing is custom and unpublished, so expect a quote process. **4. Insperity** - The choice when you want a real human HR partner, not a dashboard. PEO since 1986, CPEO-certified and ESAC-accredited, with 90+ US offices and a dedicated HR specialist assigned to each client. It's the most expensive of the group - independent 2026 analyses put all-in costs around **$150-$210/employee/month** - but it's the right call for regulated industries or messy multi-state compliance. They also offer a non-co-employment HRO option. **5. ADP TotalSource** - Pick this for Fortune 500-grade benefits and the stability of the largest payroll firm in the country. The tradeoff is real: buyers consistently rate it harder to set up and administer than Justworks, and pricing is quote-only. **6. CoAdvantage** - A solid mid-market alternative that shows up repeatedly in 2026 rankings, often competitive on price against TriNet and ADP for 20-150 employee companies. **For international hiring:** Deel is the one to use - a domestic PEO won't cover employees abroad. Justworks does offer EOR at ~$599/employee/month if you only need a couple of overseas hires. ### Two things worth knowing before you call anyone - **Check for IRS CPEO certification.** It means the PEO is solely liable for federal employment taxes - if they fail to remit, the IRS can't come after you. Justworks, Insperity, TriNet, and ADP TotalSource all have it. - **Get quotes from at least three.** PEO pricing is often a percentage of payroll rather than a flat per-employee fee, and health insurance renewal increases are where the real cost lives. Ask specifically about the renewal cap and the exit process before signing.
