EOR vs PEO
EOR and PEO are not the same thing, and the confusion between them creates real procurement mistakes. We see it regularly: a buyer evaluates an EOR when they need a PEO, or a PEO when they need an EOR, and the mismatch only becomes visible when the contract is signed and the model does not fit the situation.
The distinction is structural, not cosmetic. An EOR is the sole legal employer in countries where you have no entity. A PEO co-employs your workers in countries where you already have one. They solve different problems, require different legal infrastructure, and create different compliance chains. Choosing the wrong model does not just waste money.
It can leave you with employees who are not legally covered.
This guide explains the difference in practical terms so you can match the model to your situation before you engage a sales team.

What is the difference between an EOR and a PEO?
Buyers consistently conflate these two models, and the confusion is not trivial: one requires your own entity, the other makes that entity irrelevant. We find this distinction gets missed most often at the procurement stage, when the category label "employer of record" is applied loosely to both.
An Employer of Record (EOR) is a third-party company that becomes the sole legal employer of your workers in countries where you do not have a legal entity. You find the person, manage their work, and decide their compensation. The EOR handles the employment contract, payroll, tax filings, statutory benefits, and compliance.
You do not need an entity in that country. The EOR already has one.
A Professional Employer Organisation (PEO) is a co-employment model where the PEO shares the employer relationship with you. You must already have a legal entity in the country. The PEO handles HR administration, benefits, payroll, and compliance, but the legal employment relationship is joint. Both you and the PEO are employers of record for different purposes.
The practical consequence: if you do not have an entity in the target country, a PEO cannot help you. You need an EOR. If you already have an entity and want to outsource HR and benefits administration, a PEO may be the more cost-effective choice.
When should you use an EOR?
Use an EOR when you need to employ people in a country where you have no legal entity and do not plan to establish one in the near term.
You are hiring your first 1-15 employees in a new country. Setting up your own entity costs $50,000-$150,000 and takes 3-6 months. An EOR gets your employee on payroll in days or weeks. Below ~15 employees in a single country, the EOR platform fee ($399-$699/employee/month) is cheaper than the entity setup and maintenance cost.
Finance teams often push back on EOR costs at first glance, but the entity-setup alternative is rarely cheaper at low headcount once legal fees, registered-agent costs, and local accounting are included. We find the business case lands most cleanly when those full entity costs are modelled upfront in the procurement review.
You need to move fast. Your competitor is about to hire the candidate you have been courting. Your entity setup will not be complete for months. The EOR bridges the gap: hire now, transfer to your own entity later.
You are testing a market before committing to permanent presence. If you are not sure whether the Germany office will grow past 5 people, the EOR lets you hire without the sunk cost of entity establishment. If it works, you can transition to your own entity. If it does not, you offboard through the EOR without winding down a subsidiary.
The ceiling on EOR value is roughly 15 employees in a single country. After that, standalone payroll through your own entity ($29/employee/month) is dramatically cheaper than EOR ($399-$699/month). Plan the transition before you hit the threshold, not after. Our best EOR comparison covers the providers most buyers evaluate at this stage.
When should you use a PEO?
Use a PEO when you already have a legal entity in the country and want to outsource HR administration, benefits procurement, payroll processing, and compliance management, while retaining the employment relationship.
You have a US entity and want access to large-group benefits rates. This is the most common PEO use case. A PEO like Justworks or TriNet pools your employees with thousands of others to negotiate health insurance, retirement plans, and workers' compensation at rates that a 20-person company could not access alone.
For a small US business, the benefits cost saving can exceed the PEO fee.
We consistently see this value proposition resonate most strongly with companies in the 15-75 headcount range, where self-administering benefits is genuinely painful but a dedicated benefits team is not yet justified.
You want to outsource HR without giving up the employer role. With a PEO, you remain a co-employer. You retain control over hiring, firing, compensation, and day-to-day management. The PEO handles the administrative burden: payroll processing, tax filings, benefits enrolment, and compliance monitoring.
If you have an HR team of one and 50 employees, the PEO scales your administrative capacity without adding headcount.
You operate in the US and want someone else to handle multi-state payroll compliance. State-level payroll tax, workers' compensation, and employment law create compliance complexity that scales with every state you hire in. A PEO handles that complexity for you, as long as you have the underlying entity.
The key constraint: PEOs require your own entity. They are common in the US but rare internationally. If you need to hire in a country where you have no entity, a PEO cannot help you. You need an EOR.
How do the costs compare?
The cost structures are fundamentally different because the models solve different problems at different scales.
EOR is 3-7x more expensive than PEO on a per-employee basis because the EOR assumes the full legal employer role: entity maintenance, compliance liability, statutory benefits, and tax filing. A PEO shares that burden with your existing entity.
If you have an entity and more than 15 employees in a country, the PEO or standalone-payroll route is almost always cheaper than maintaining an EOR relationship. The EOR premium pays for speed and entity-free access, not for long-term cost efficiency.
We notice that buyers who do not model the break-even point before signing an EOR contract consistently underestimate how quickly the cost delta compounds at scale.
Whichapp view
The most expensive mistake buyers make is not choosing the wrong model, it is staying on the wrong model too long.
Companies that start with EOR and never transition to their own entity or PEO when headcount grows past 15 are overpaying by $4,000-$8,000 per employee per year.
Build the transition trigger into your expansion plan from day one. When you pass 15 employees in a country, start the entity-setup process. Do not wait until you are at 30 and have been overpaying for a year.
What are the common mistakes?
Using EOR when you already have an entity. If you have a legal entity in a country, you do not need an EOR to hire there. Standalone payroll ($29/employee/month) or a PEO ($89-200/month) will serve you at a fraction of the EOR cost.
We see this mistake when a company has a UK entity but uses an EOR for UK hires because the procurement team does not realise the entity already covers local employment.
Using a PEO when you have no entity. A PEO requires your own entity to co-employ. If you are hiring in a new country without one, the PEO model simply does not work. You need an EOR, or you need to establish an entity first.
Confusing co-employment with sole employment. In a PEO arrangement, both you and the PEO are employers. This means liability is shared, not transferred. If the PEO makes a payroll error, you share the consequences. In an EOR arrangement, the EOR is the sole employer and assumes the compliance liability.
The risk transfer is different, and your legal team should understand which model applies before sign-off.
Legal and Procurement teams that flag this distinction late in the vendor evaluation often stall the procurement process for weeks: the contract terms for co-employment require different indemnity clauses than those for sole-employer EOR arrangements, and most standard templates assume one or the other, not both.
Staying on EOR past the break-even point. The transition from EOR to your own entity typically makes financial sense at ~15 employees in a single country. The entity setup costs $50,000-$150,000 and takes 3-6 months, but the ongoing saving of $4,000-$8,000/employee/year means the investment pays back within 6-12 months at 15+ headcount.
Most buyers wait too long to make this transition because the EOR relationship is comfortable and the entity-setup project is daunting. Finance teams rarely flag it unprompted, since the EOR cost sits in a vendor line rather than a headcount line and does not surface in the same budget review.
Frequently asked questions
Can you use an EOR and a PEO at the same time?
Yes. A common setup is EOR for countries where you have no entity and PEO (or standalone payroll) for countries where you do. This is operationally sensible, you use the right model for each market.
The trade-off is managing multiple provider relationships and reconciling reporting across them.
Is PEO available outside the US?
PEO is primarily a US model. The co-employment framework that PEOs rely on is well-established in US employment law but has limited recognition internationally. Some providers offer "international PEO" but these are often EOR services marketed under the PEO label. If a provider calls their international product a PEO, ask whether it requires your own entity in the target country.
If it does not, it is an EOR regardless of what they call it.
Which EOR providers also offer PEO?
Deel offers US PEO from $89-95/employee/month alongside its EOR product. Justworks is a dedicated PEO. Rippling offers PEO-like co-employment alongside its HRIS platform.
- Most international EOR providers (Remote, Multiplier, Oyster, Papaya Global) do not offer PEO because the model is primarily US-focused.
When should you stop using EOR and set up your own entity?
Roughly 15 employees in a single country. At that threshold, the ongoing EOR fee ($399-$699/employee/month) exceeds the amortised cost of entity setup ($50,000-$150,000) plus standalone payroll ($29/employee/month). Start the entity-setup process 6 months before you expect to hit 15, not after you have been overpaying for a year.
Most EOR providers offer Global Payroll products that handle the transition.
