EOR vs PEO: What's the Difference and Which Does Your Company Need?
EOR and PEO are often confused but serve very different purposes. EOR is for international hiring without a local entity. PEO is for US domestic payroll outsourcing. Here's how to tell which you need.

Two terms that cause consistent confusion in discussions about HR infrastructure for growing companies: EOR (Employer of Record) and PEO (Professional Employer Organization). They sound related, they occupy adjacent space in HR vendor sales conversations, and many platforms offer both. They serve fundamentally different purposes, and choosing the wrong one for your situation is a meaningful mistake.
The short version: EOR is for hiring people internationally in countries where you don’t have a legal entity. PEO is for outsourcing domestic US HR administration and payroll. If you’re building a distributed global team, you need to understand EOR. If you’re a US company that wants to outsource your HR administration to reduce overhead, you’re looking at PEOs.
The longer version — including when the lines blur, what each model costs, and how to choose — follows.
What an Employer of Record (EOR) Does
An Employer of Record is a third-party company that becomes the legal employer of your workers in a specific country. The EOR handles all legal obligations of employment in that country: payroll processing, tax withholding, benefit administration, labor law compliance, employment contracts compliant with local law, and termination procedures.
You direct the employee’s work as the client company. The EOR employs them on your behalf. This arrangement is sometimes called “co-employment,” though the term is used more precisely in the PEO context — in EOR arrangements, the EOR is the employer of record, not a co-employer in the legal sense.
When You Need an EOR
You want to hire someone in a country where you have no legal entity. This is the core use case. Starting a hiring relationship in Germany, Brazil, Singapore, or India without a local legal entity means the EOR becomes the legal employer in that country. Without an EOR (or establishing your own entity), you cannot legally employ someone there.
You want to test a new market before committing to entity establishment. Establishing a local legal entity costs $10,000-$30,000+ in legal and setup fees plus ongoing compliance overhead. EOR lets you hire 1-5 people in a market to validate it before that investment.
You have contractors who should be classified as employees. Worker classification risk — the risk of a contractor being reclassified as an employee under local law — is significant in many jurisdictions. EOR converts that relationship to proper employment, eliminating the risk.
You’re scaling globally and do not want to establish entities everywhere. A company with employees in 15 countries does not need 15 legal entities. EOR handles the employment in each country without the entity overhead.
What EOR Does Not Cover
EOR is not a domestic US solution. If you’re a US company hiring US employees, EOR is not what you need — you either handle payroll and HR internally or use a PEO.
EOR also does not replace your need for an HRIS. It handles the legal employment relationship in each country, but it does not provide the performance management, employee records, time-off management, and HR analytics you need across your workforce. You will typically use an EOR alongside a core HRIS.
What a Professional Employer Organization (PEO) Does
A PEO enters into a co-employment relationship with you and your employees. In this model, the PEO and your company are both considered employers of your workers for specific purposes. The PEO handles payroll administration, tax filings, benefits administration, and HR compliance. You handle everything related to the employee’s work — management, performance, business operations.
The co-employment structure is meaningful: the PEO shares certain employer liabilities and obligations, which enables it to offer benefits across its entire client base. Because a PEO pools thousands of employees across its clients, it can negotiate large-group rates for health insurance and other benefits that a small company could not access on its own.
When You Need a PEO
You’re a US-based company that wants better benefits at lower cost. PEOs pool client employees to negotiate large-group health insurance rates. A company with 20 employees on a PEO can access the same health insurance rates as a 5,000-person company. This is often the primary financial argument for PEO.
You want to outsource domestic HR administration. PEOs handle payroll processing, tax filings, workers’ compensation, unemployment insurance, and HR compliance for your US workforce — reducing the administrative burden on your internal HR team.
You don’t have an internal HR function but need HR capabilities. For small companies (under 50-100 employees) that cannot justify a full HR department, PEOs provide the HR infrastructure — benefits administration, HR advisory services, compliance support — without the headcount.
You’re in a state or industry with complex compliance requirements. PEOs provide compliance expertise in employment law, workers’ compensation, and benefits that small internal HR teams may not have.
What PEO Does Not Cover
PEOs are primarily a US domestic solution. They do not handle employment in other countries in the way EOR does. A few PEO providers offer international EOR services alongside their domestic PEO offering, but the two services remain distinct.
PEO also requires a co-employment relationship that not all companies want. Some states and industries have restrictions on PEO arrangements. And the benefits pooling model means your employees’ benefits are tied to the PEO’s group — if you leave the PEO, benefits transition can be disruptive.
EOR vs PEO: Direct Comparison
| EOR | PEO | |
|---|---|---|
| Primary use case | International employment in countries with no local entity | US domestic payroll and HR outsourcing |
| Legal structure | EOR is the sole employer in the target country | Co-employment between PEO and client company |
| Geographic scope | Cross-border, typically 50-150+ countries | Primarily US; some PEOs have international arms |
| Benefits impact | Provides local market benefits per country | Pools benefits across clients for group rates |
| Typical company size | Any company hiring internationally | Typically 5-500 US employees |
| Why companies use it | To hire without establishing local entities | To access better benefits and reduce HR overhead |
| Integration with HRIS | Supplements existing HRIS with international payroll | Often includes basic HRIS functionality |
| Leading providers | Deel, Remote, Oyster, Rippling EOR, Papaya Global | ADP TotalSource, TriNet, Insperity, Justworks, Gusto |
Can You Use Both?
Yes, and many companies do. A US company with 50 domestic employees and 10 international employees might use a PEO for the domestic workforce (for benefits access and HR administration) and an EOR for the international workforce (for legal employment in each country).
Some platforms now offer both under one roof — Rippling, for example, handles US payroll and HR alongside international EOR and global payroll in a unified system. This consolidated approach has become an attractive option for companies scaling both domestically and internationally, because it keeps all workforce data in a single system.
The Hybrid: Global PEO
Confusingly, some providers use the term “Global PEO” to mean what is functionally an EOR service for international markets. This is primarily a marketing terminology choice rather than a meaningful structural distinction. If a provider describes their international service as “Global PEO,” ask them specifically whether they are the legal employer in each country or whether they enter into a co-employment arrangement. The answer tells you which model they actually operate.
How to Decide
If you’re hiring internationally where you have no entity: You need an EOR. Start with the leading EOR platforms.
If you’re a US company looking to outsource HR administration and improve benefits: You need a PEO. Evaluate ADP TotalSource, TriNet, Insperity, or Justworks depending on your size and needs.
If you’re scaling both domestically and internationally: Evaluate platforms that handle both — Rippling is the leading option — or run a PEO for domestic and an EOR for international.
If someone is trying to sell you a “Global PEO” for international hiring: Ask for clarification on the legal structure. It may be EOR under a different name, or it may be something genuinely different. The key question: in each country, is your platform the legal employer?
Frequently Asked Questions
Is EOR cheaper than establishing a local entity? For small headcount per country (1-10 employees), yes — typically significantly. EOR monthly fees ($499-599/employee/month for major providers) are less than the annualized cost of establishing and maintaining a local entity. At 10-15+ employees per country, entity establishment typically becomes more cost-effective.
Does a PEO protect against employment lawsuits? PEOs share co-employer liability in some respects, which can provide some protection. However, co-employment means shared liability, not eliminated liability. Your legal exposure as the client company remains real — particularly for management decisions, discrimination claims, and wrongful termination. Do not choose a PEO primarily for liability protection; consult legal counsel on your actual exposure.
Can I use an EOR to hire in the US? Yes, some EOR providers offer US domestic EOR services. This is different from a PEO — the EOR becomes the sole employer, not a co-employer. Some companies use US EOR to hire workers in states where they have no presence and want to avoid establishing payroll nexus. However, for most US hiring, standard domestic payroll processing (or a PEO for the benefits and administration benefits) is more common and often more cost-effective.
What happens to my employees if I switch from PEO or EOR? For PEOs, the transition involves moving employees back onto your own payroll or onto a new PEO — a significant benefits transition event that requires communication and careful timing. For EOR, employees typically need new employment contracts with the new EOR provider. Neither transition is trivial, which is why choosing the right provider from the start matters.
EOR and PEO solve different problems for companies at different stages. The confusion between them is understandable — both involve outsourcing employment administration, both use the word “employer,” and some providers offer both. But the underlying models, use cases, and cost structures are distinct enough that using the wrong one for your situation creates meaningful problems.
