EOR vs PEO: the difference and how to choose

A PEO fits your company if you already have a legal entity and want to share HR administration; an EOR fits your company if you need to hire in a country where you have no entity at all. Both outsource employment-related HR work, but only one of them becomes the legal employer, and that difference drives everything else that follows: cost, country access, and liability. This guide compares the two head to head; for the fuller picture of how the EOR model works on its own, see our employer of record guide.

A PEO co-employs your workforce alongside your own legal entity, while an EOR becomes the sole legal employer and lets you hire without one. Both models overlap on payroll processing, benefits administration, and compliance support, but they diverge on liability, cost, speed, and which countries you can reach, as the table below shows.

The gap in price traces back to the gap in liability. A PEO shares legal responsibility with you and only operates where you already hold an entity, which keeps its fee lower. An EOR takes on that responsibility alone, in countries where you have no presence at all, which is what its higher fee buys.

A PEO's advantages come from pooling many client companies together, which gives a single business access to resources it couldn't negotiate alone. Affordable benefits, lower administrative costs, and reduced risk all follow from that shared scale.

The trade-off is flexibility. Most PEOs sell bundled packages, so you may pay for features you don't need, and sharing sensitive employee data with a third party carries its own privacy risk.

An EOR's advantages come from standing in as the legal employer, which removes the compliance and entity-setup work that normally blocks international hiring. Global reach, reduced legal risk, and hiring flexibility all follow from that role.

The trade-off is cost and consistency. EOR fees run higher over time than a PEO's, and standardized benefit packages are often less competitive than what you could negotiate directly.

A PEO shares legal employer status with your company under a co-employment arrangement, while an EOR is the sole legal employer and carries full compliance liability on its own. With a PEO, you remain the legal employer of record and keep control of daily operations, while the PEO handles administrative HR tasks and shares exposure for tax and compliance failures alongside you. With an EOR, the EOR's name appears on the employment contract, the pay stub, and the tax filings, while you keep control of the employee's day-to-day work and performance.

That split changes who is on the hook when something goes wrong. A PEO's co-employment model means both parties can be held responsible if payroll tax or compliance work fails. An EOR's sole-employer model shifts that liability to the EOR, though it doesn't remove every risk from your side: if EOR-employed workers generate revenue, negotiate contracts, or otherwise create a fixed place of business in a country, the local tax authority can determine your company has a permanent establishment there, triggering local corporate tax obligations regardless of the EOR relationship. See EOR legal risks for how to structure roles to avoid it.

Termination liability is part of that same calculation. Statutory notice periods vary widely by country: the median across the 198 countries in our dataset is 4.3 weeks, and the highest we track is Gambia at 26 weeks, per our Global Employer Burden Index dataset (198 countries). An EOR is expected to know and apply the correct figure in every country it employs for you; under a PEO, your company still carries that responsibility because it remains the legal employer.

A PEO typically charges 3% to 12% of gross payroll or $50 to $150 per employee a month, while an EOR charges $99 to $799 per employee a month. Both price on a per-employee or percentage basis, but the EOR's higher fee reflects the full legal-employer liability it takes on, not just the administrative work.

A PEO's fee covers payroll processing, employee benefits, compliance support, and workers' compensation, priced either as a percentage of payroll or a flat monthly rate. An EOR's fee covers the same functions plus full legal employment, contracts, and immigration paperwork where needed, which is why it commands a higher rate per employee. Cost also depends on employee location, workforce size, and whether your company already holds a legal entity in the target country.

Employer social security contributions sit on top of either fee and can swing the total further. The median employer social security contribution across the 196 countries in our dataset is 12.6%, and the highest we track is New Caledonia at 36.49%, per our Global Employer Burden Index dataset. A cheap-looking PEO or EOR quote in a high-contribution country can still produce a high total cost of employment, so ask for a full breakdown before you sign. See the cost of an EOR for the full breakdown by fee type and hidden charge.

A PEO can only hire and manage employees in countries where your company already has a legal entity, while an EOR lets you hire in countries that permit third-party employment, without setting one up first. That single difference decides which model is even an option for a given market.

The PEO model is primarily a US structure, built on co-employment under federal and state law, including IRC §3511 for certified PEOs and state-level PEO licensing statutes. Outside the US, equivalent arrangements, such as UK umbrella companies, work differently, so a PEO's reach is generally limited to markets where you already operate and where that legal structure exists.

An EOR's reach is wider but not unlimited. Major providers cover 80 to 170 or more countries, though the depth of that coverage depends on whether the provider owns the local entity or relies on a local partner, and on whether local law recognizes third-party employment relationships at all. See global EOR hiring for coverage by country.

A PEO co-employs your existing workforce and manages HR tasks like payroll, benefits, and compliance, while a staffing agency recruits and places workers with client companies, often on a temporary or contract basis, and may remain their employer during the placement. A PEO is for companies that already have staff and want HR support. A staffing agency is for companies that need to find and place workers quickly.

An EOR sits in a different spot again. A staffing agency sources and places candidates; an EOR takes over after that point, handling onboarding, payroll, and compliance for people you've already decided to hire. For a fuller breakdown of that comparison, see EOR vs staffing agency.

Choose a PEO for domestic HR support, an EOR for hiring internationally without a legal entity, and a staffing agency for filling temporary or contract roles quickly. Work through three questions to confirm which one fits your situation.

First, consider your business goal. If you want to hire in a market where you have no legal entity, an EOR lets you hire and manage employees in countries that permit third-party employment, without setting one up first. If you're expanding locally and want HR support, a PEO is the more practical option.

Second, consider how many employees you plan to hire. Many PEOs require a minimum headcount before they'll take you on as a client. An EOR works with businesses of any size, which makes it a strong option if you're hiring 1 to 20 employees in a single location.

Third, ask whether you already have a legal entity in the target country. If you do, a PEO can pick up HR administration without disrupting that structure. If you don't, and don't want to set one up, an EOR is the more practical path. If you only need workers placed fast for a short-term project rather than an ongoing hire, a staffing agency fits better than either.

Choose an EOR if you need to hire in a country where you have no legal entity; choose a PEO if you already have that entity and want shared HR support instead of full legal transfer. Match your choice to your entity status and headcount first, then compare providers.

• Choose an EOR if you're hiring 1 to 20 employees in a country where your company has no legal entity.
• Choose an EOR if you need to test a new market before committing to a permanent presence.
• Choose an EOR if you're converting contractors to employees or absorbing staff from an acquisition.
• Choose a PEO if you already have a legal entity in the country and want to outsource payroll, benefits, and compliance.
• Choose a PEO if your hiring is domestic and you want group-rate benefits without negotiating them yourself.
• Choose a staffing agency if you need workers placed fast for a temporary or contract role rather than a direct hire.

If you've settled on an EOR as the right model for your expansion, the next step is working out how to choose and implement an EOR for your specific markets and headcount. If a PEO fits better, start with our PEO guide to see how providers and pricing compare.
