The main difference between a PEO and an EOR is that a professional employer organization (PEO) provides HR services under a co-employment arrangement, while an employer of record (EOR) acts as the legal employer handling employment tasks for your workers in countries where you don’t have an entity. For more details, see our guide on what an Employer of Record is and how to choose the right EOR for your business.
Choosing between a PEO and an EOR comes down to where you’re hiring, whether you have local entities, and how much employment liability you want to retain. This guide breaks down every key difference so you can make the right call.
What is a Professional Employer Organization (PEO)?
A PEO is a company that provides outsourced HR services to small and medium-sized businesses under a co-employment model.
PEO services typically include:
- Payroll processing
- Benefits administration
- Regulatory compliance support
- Tax filings
- Workers’ compensation insurance
- Employee onboarding and offboarding
The PEO acts as a co-employer — your business remains the official employer, while the PEO shares responsibility for HR functions. This means your company retains legal accountability for employment decisions, payroll accuracy, and compliance with local labor laws.
When you work with a PEO, your company is still accountable for both legal and day-to-day operations, including registering your business where you hire talent.
What is an Employer of Record (EOR)?
An employer of record (EOR) is a company that acts as the legal employer for your workers in countries where you don’t have your own entity. The EOR owns local entities and handles all employment obligations on your behalf.
The EOR is responsible for:
- Locality-specific onboarding and employment contracts
- Payroll processing and tax withholding
- Compliance with local labor laws
- Benefits administration
- Visa and work permit sponsorship
- HR-related employee support and offboarding
EORs provide these services to businesses that need to hire employees in locations — often different countries — where they don’t have a legal entity. By using an EOR, businesses can outsource the administrative and legal tasks of employment and focus on their core operations.
If you want to hire remote employees without an EOR, you’ll need to set up your own business entities in each country — a process that typically takes 4-12 months and costs $15,000-$80,000+ per entity.
PEO vs. EOR: Side-by-Side Comparison
| Feature | PEO | EOR |
|---|---|---|
| Employment model | Co-employment | Sole legal employer |
| Geographic scope | Primarily US domestic | International (180+ countries) |
| Requires your own entity | Yes | No |
| Employment liability | Shared (co-employment) | EOR assumes liability |
| Minimum employees | Usually 5-10 | No minimum (hire 1+) |
| Setup time | 2-4 weeks | 1-5 business days |
| Entity setup cost | $15,000-$80,000+ per country | $0 (EOR has entities) |
| Best for | Domestic HR outsourcing | International hiring without entities |
| Worker classification | Employees only | Employees and contractors |
| Insurance | You may need your own | EOR provides GL and WC |
| PE risk | Lower (domestic) | Higher — see PE risks |
| Cost structure | Flat fee + % of payroll | Flat monthly fee per employee |
Key Differences Explained
A PEO acts as a co-employer, meaning your organization still has exposure to employment liabilities — though a PEO can help manage those risks. You share the legal burden.
An EOR acts as the actual employer of your workforce and assumes all employment risks and liabilities related to the services it offers. This means your organization doesn’t carry the burden of employment liabilities such as workplace safety claims, wrongful termination suits, or tax compliance failures.
This is the single most important distinction. If you want to employ full-time workers in a country where you don’t have a legal entity, you must use an EOR — it’s your only option (other than opening your own entity). A PEO cannot employ workers in countries where you don’t already have a registered business.
Setting up your own entity can take 4-12 months and cost $15,000-$80,000+ per country, plus ongoing compliance and accounting costs. An EOR eliminates this entirely — you can start hiring in days.
If you already have a legal entity in the country where you want to hire, a PEO can provide services such as payroll and benefits to supplement your existing HR infrastructure.
Most PEOs require a minimum of 5-10 employees to engage their services. EORs typically have no minimum requirement — you can hire a single employee in a given country.
This makes EORs the better option for small businesses, startups, and companies testing new markets. PEOs are better suited for businesses with larger domestic workforces that need HR support.
EORs typically provide general liability (GL) and workers’ compensation (WC) insurance as part of their service. PEOs may require you to provide your own insurance — particularly in non-clerical industries where securing WC coverage can be difficult.
When evaluating providers, ask specifically what insurance is included and what you’ll need to provide yourself.
PEOs and EORs both typically charge a flat monthly fee per employee or a percentage of monthly payroll. However, the total cost profile differs significantly:
- PEO costs: Monthly per-employee fee (typically $100-$200/employee/month) + percentage of payroll (2-4%) + your own entity costs + insurance costs. Total: often $500-$1,500+ per employee per month when all costs are included.
- EOR costs: Flat monthly per-employee fee (typically $400-$700/employee/month). No entity setup costs, no separate insurance, no minimums. See our breakdown of EOR service costs.
An EOR typically costs less overall because it covers insurance and benefits for your distributed workforce, while with a PEO you’re still responsible for those costs on top of the PEO’s fees.
EORs offer significantly more flexibility than PEOs:
- Hire one employee or many — no minimums
- Add employees in new countries without entity setup
- Onboard employees in 1-5 business days vs. 2-4 weeks for PEO
- Manage both employees and contractors on the same platform
- Scale up or down quickly without long-term commitments
PEOs are better for companies that have established domestic operations and need ongoing HR support for a stable, larger workforce.
You don’t need an EOR or a PEO to work with international contractors — you simply need a compliant contractor management and payment solution. Both EORs and PEOs can facilitate contractor payments, but EOR platforms typically include built-in contractor management features.
Be careful about misclassification risk — if you’re directing a contractor’s work as if they were an employee, you may need to convert them to an EOR arrangement to stay compliant.
PEO vs. EOR: Which Should You Choose?
Choose an EOR if:
- You want to hire employees in countries where you don’t have a legal entity
- You need to onboard employees quickly (days, not months)
- You have a small team or are testing new markets
- You want the EOR to assume all employment liability
- You hire both employees and contractors internationally
Choose a PEO if:
- You already have a legal entity where you’re hiring
- You have a larger domestic workforce (10+ employees)
- You want to retain legal employer status and control
- You need comprehensive HR outsourcing for US-based operations
- You’re comfortable sharing employment liability under co-employment
Regardless of whether you choose a PEO or an EOR, hiring talent across borders is complex. Adhering to unfamiliar labor laws and regulations can be difficult and costly, and non-compliance can lead to fines, penalties, or loss of the talent you set out to hire. Work with a partner who understands these complexities — and verify their expertise in every country where you operate.
When choosing between an EOR and a PEO, also be aware that some EORs work through third-party partners to employ workers in other countries instead of doing so directly. This can lead to inconsistent service and unexpected costs. Choose an EOR that owns its own legal entities in the countries where it offers services for the most reliable experience.
