No jargon. No sales pitch. Everything a business owner needs to understand before deciding whether a PEO is worth exploring.
A Professional Employer Organization is a company that co-employs your workforce. They become the employer of record for administrative purposes — handling payroll, taxes, benefits, workers comp, and HR compliance — while you retain full control of your business operations.
The co-employment arrangement allows the PEO to pool your employees with thousands of others, which gives your business access to Fortune 500-level benefits at a fraction of the cost it would take to build that infrastructure independently.
The short version: You run your business. They run the back-office HR. You get enterprise-grade benefits and compliance support. You pay a fee per employee per month — and in most cases, the savings on benefits and risk management more than offset the cost.
Processing payroll, managing tax withholdings, filing W-2s, handling garnishments and deductions. The PEO takes on significant payroll tax liability as a co-employer.
Health, dental, vision, life, and disability insurance — typically at rates a small employer could never negotiate independently. Many PEOs also offer 401(k), HSA, and FSA plans.
Coverage under the PEO's master policy, often at better rates than a small employer qualifies for. Claims management, safety programs, and return-to-work coordination.
Employee handbook development, EPLI coverage, ACA compliance, I-9 administration, multi-state employment law guidance, and HR advisory on employee relations issues.
Online onboarding, time and attendance tracking, benefits enrollment portals, PTO management, and employee self-service tools — typically included in the PEO fee.
Unemployment claims management, OSHA assistance, workplace safety programs, and shared employer practices liability — reducing your exposure across multiple risk categories.
PEOs typically use one of two pricing models:
A flat monthly fee per employee. Common range: $100 to $250 per employee per month, depending on company size, industry, and services included.
Best for: Businesses where pricing predictability matters. Easier to budget and model.
A percentage of your total payroll. Common range: 2% to 12%, depending on the same factors.
Best for: Businesses with variable payroll. Cost scales with your team's compensation.
Important: These are administrator fees only. Benefits costs are typically separate and pass through at the negotiated group rate. An experienced advisor can tell you exactly what your all-in cost should look like before you talk to a single PEO.
A Certified Professional Employer Organization (CPEO) has been certified by the IRS, meeting specific financial and operational standards. CPEO status matters for two reasons:
| Model | PEO | ASO | EOR |
|---|---|---|---|
| Co-employment | Yes — shared employer of record | No — you remain sole employer | Yes — EOR is the legal employer |
| Best for | 5-150 employee US-based businesses | Businesses that want admin help without co-employment | Hiring in countries where you have no legal entity |
| Benefits pooling | Yes — group purchasing power | Limited | Yes, but at EOR's rates |
| Typical cost | $100-250 PEPM or 2-12% payroll | $50-150 PEPM | $500-2,500+ PEPM |
A PEO tends to make the most sense when three or more of these apply:
