A PEO shares employment responsibilities with you through a co-employment model. You remain a legal employer. The PEO becomes a co-employer. Together, both entities share liability for payroll, benefits administration, workers’ compensation, and HR compliance. The critical difference from an EOR: a PEO requires you to already have a legal entity in the country where the employee works. An EOR does not.
PEOs are overwhelmingly a US model. Roughly 175,000 US businesses use PEOs, covering about 4 million employees according to the National Association of Professional Employer Organizations (NAPEO). The value proposition is straightforward: small and mid-size companies that lack bargaining power with health insurers can access Fortune 500–level benefits through the PEO’s pooled purchasing. A 20-person startup paying $800/month per employee for health insurance might get the same plan at $550/month through a PEO’s group rate. The PEO also handles payroll tax filings, unemployment insurance management, and workers’ compensation administration — back-office functions that consume disproportionate time in small companies.
Outside the US, the PEO model is rare. Most countries’ employment frameworks don’t accommodate co-employment cleanly. France, Germany, and Japan each have strict definitions of who the “employer” is, and dual employer structures create ambiguity around liability, mandatory benefits obligations, and termination authority. In most international contexts, what you actually need is an EOR — a single entity that takes full employer responsibility while you maintain operational control.
The terminology confusion is real and deliberately exploited. Sales teams at some providers use “global PEO” when they mean EOR. The test is simple: do you need your own entity in-country? If yes, it’s a PEO arrangement. If no, it’s an EOR. The legal structures, liability models, and compliance responsibilities are fundamentally different. Don’t let marketing terminology blur that line.
Why It Matters for EOR
Understanding the PEO/EOR distinction matters because choosing the wrong model creates real operational problems. If you’re entering Germany with no local entity and a provider sells you “PEO services,” you’ll discover you still need to register a GmbH — a process that takes 4–8 weeks and costs €10,000–25,000 in legal and registration fees. If you wanted to avoid entity setup entirely, you needed an EOR, not a PEO.
The reverse scenario also applies. If you already have a legal entity in-country and only need payroll and benefits administration, paying an EOR’s per-employee fee ($299–$699/month) is overpaying for a service a PEO can provide at lower cost. PEO pricing typically runs 2–12% of total payroll — which for a US employee earning $100,000 means $2,000–$12,000 annually, often less than EOR pricing for the same function.
Some providers straddle both models. Rippling started as a US PEO/HRIS platform and expanded into global EOR. Deel offers both EOR and “direct employee” management (effectively PEO-adjacent) for companies with existing entities. When evaluating providers, map your entity footprint first — which countries do you already have entities in, and where are you hiring without one? That determines whether you need EOR, PEO, or a mix. A comparison of leading providers can help clarify which platforms support both models effectively.
