PEO vs EOR: When Each Wins (and When You Need Both)

A PEO shares the employer relationship with you. Co-employment means the PEO is the legal employer for tax, benefits, and workers' comp purposes; you stay the worksite employer who hires, fires, and manages. The structure works within the US — every US state has its own labor laws, but PEOs operate across all 50.

An EOR (Employer of Record) becomes the sole legal employer in the country or state where it operates. There's no co-employment — the EOR's legal entity in France employs your French engineer; you don't have a French entity at all. The EOR handles French payroll, taxes, statutory benefits, and labor law compliance under its name; you direct the engineer's work but have no direct employer relationship.

The distinction matters operationally. Under co-employment, your company's name still shows up on most employment paperwork (W-2s show "PEO + your company"). Under sole employment via EOR, the EOR's name is on everything — your employee is technically employed by Deel or Remote or Velocity Global, not by you.

International hiring without a foreign entity. Establishing a legal entity in France, Germany, India, Brazil, or Mexico costs $50K–$200K in setup plus ongoing accounting, tax filings, and compliance overhead. For hiring two engineers in Poland, the math doesn't work. An EOR employs the worker in-country under its existing entity and bills you a fee — typically 10–20% of gross salary, plus actual employment costs.

Test-hiring before committing to a country. Want to see if a sales team in the UK works before establishing UK operations? EOR for the first 1–3 hires lets you trial without commitment. If it works, establish your own entity at scale (typically year 2+); if it doesn't, you exit cleanly.

Remote-first companies hiring globally. If your hiring strategy is "best talent regardless of location," an EOR is the operational backbone. Deel, Remote, Velocity Global, and Globalization Partners handle 100+ countries between them.

US states where you have no legal presence. Less common but real — if you're a California company and want to hire one person in Wyoming or Hawaii without registering as an employer in that state, an EOR can bridge the gap. Most PEOs handle US multi-state registration; an EOR is the alternative when registration friction is too high for a single hire.

You're hiring US-based employees. PEOs are deeply optimized for the US market — multi-state tax filing, IRS-certified payroll handling, group health insurance master plans negotiated with Aetna, UnitedHealthcare, Anthem, BCBS, and Kaiser at 50,000-life scale. EORs don't do master-plan benefits at PEO scale.

You want bundled HR services. PEOs include payroll + benefits + workers' comp + HR compliance + ACA reporting + EPLI policy under one contract. EORs deliver employment but typically don't bundle equivalent HR services — they're focused on the legal-entity substitution.

Group benefits buying power matters more than international flexibility. A 50-person US tech company gets 15–30% lower health premiums through a PEO master plan than they'd get solo. An EOR can't replicate that — EORs price benefits country-by-country, often at standalone rates.

Cost per US employee. PEOs run $80–$220 PEPM, which is $1,200–$2,600 per US employee per year. EORs run 10–20% of salary, which is $10,000–$20,000 per international employee at $100K compensation. PEOs are dramatically cheaper for US employees because they're aggregating across millions of US workers; EORs are per-country and don't pool to the same degree.

The most common pattern we see at growth-stage companies: PEO for the US team, EOR for international hires. The two systems run in parallel without conflict.

A typical setup at 75 employees:

• 50 US W-2 employees — on a PEO (Insperity, TriNet, Justworks, etc.)
• 15 international employees across 4 countries — through an EOR (Deel or Remote)
• 10 US 1099 contractors — through a contractor-payments platform (Deel Contractor, Wise Business, direct ACH)

Your finance team sees three separate vendor relationships; your HR team manages them through different portals. That's manageable up to ~500 employees. Above that, most companies start consolidating — either by establishing their own foreign entities (eliminating EOR fees) or moving to a single global HR platform with built-in EOR partnerships.

What's NOT a good idea. Trying to use a PEO's "global expansion" service to replace an EOR — most PEO global services are EOR partnerships layered on top, often at higher cost than going to the EOR directly. Go direct to the EOR.

For a single employee at $100K compensation:

• PEO (US-based employee): $145 PEPM × 12 = $1,740/year in PEO fees. Plus actual benefits premium pass-through (you pay carrier rates) and workers' comp pass-through. Total PEO-attributable cost: ~$1,740–$2,600/year.
• EOR (international employee): 12% of $100K salary = $12,000/year in EOR fees. Plus actual employer-side taxes (varies by country, typically 15–35% of gross), plus statutory benefits. Total EOR-attributable cost: ~$12,000–$15,000/year (excluding salary and statutory employer costs).

The cost gap is huge but the value proposition is different. PEO replaces in-house HR functions you'd otherwise build. EOR replaces a foreign legal entity you'd otherwise establish. Per-employee cost comparison misses the point.

Three questions answer the PEO-vs-EOR decision cleanly:

1. Where is the employee located? US → PEO is in play. Outside US → EOR is the answer (PEO doesn't serve international).

2. Do you have a legal entity in the country/state where the employee will work? Yes → you can hire directly (and use a PEO or in-house HR for US, or your own foreign entity for international). No → EOR for that location, or establish an entity.

3. What's your headcount in that country/state? Under 5 employees per country → EOR usually wins. 5–10 employees → break-even with entity establishment depending on country. 10+ employees → typically time to establish your own entity.

The hybrid answer is more common than either-or. Most growing companies use a PEO for their US team and an EOR for international hires until they're ready to establish foreign entities. See our PEO comparisons hub for the full alternatives landscape.
