PEO vs. EOR: Differences and which is right for you

Employing new team members compliantly can be challenging, especially as teams expand across regions. That's where a professional employer organization (PEO) and an employer of record (EOR) come in. The main difference? A PEO shares employment duties with your company, while an EOR is the legal employer for your team members.

This article compares a PEO versus an EOR across compliance responsibilities, payroll management, and employee benefits. It also explores scenarios to help you decide which approach best aligns with your organization’s goals. 

Overview of PEO vs. EOR models

Both PEOs and EORs make it easier for companies to manage HR and compliance tasks more efficiently. Let’s break down each model, how it operates, and the impact on your organization.

What is a PEO?

A PEO partners with your company to share certain employment obligations. You remain the legal employer and manage day-to-day operations, while the PEO handles the following through a co-employment model:

• Managing payroll, taxes, and employee benefits
• Providing HR support and compliance guidance
• Offering group benefits plans that your team can join
• Complying with local legal entity requirements

What is an EOR?

While you still maintain operational control over your company, an EOR assumes full legal responsibility for employing your team members. It handles tasks such as: 

• Processing payroll, managing taxes, and ensuring compliance with local labor laws
• Hiring globally without creating a local entity
• Carrying legal and administrative employment obligations

PEO vs. EOR: 4 differences you should know

PEOs and EORs lighten your workload but function differently behind the scenes. Here’s how the two compare across four key areas. 

1. Employment structure

A PEO operates under a co-employment model, where your company and the PEO share the employment relationship. This means you supply the PEO with the information and funding it needs to manage HR administration, including payroll and tax filings. This setup requires a registered business entity in every country where you employ people. 

An EOR, on the other hand, assumes full legal responsibility. It signs local contracts, processes payroll, and ensures compliance with local labor laws—all through its own entities. You direct daily work, while the EOR carries the legal administrative obligations of employment.

2. Liability and compliance

With a PEO, your company shares legal responsibility for the compliance and employment practices. If a dispute or filing arises, you're jointly liable.

An EOR removes that shared risk. As the legal employer, the EOR manages payroll accuracy, tax compliance, and adherence to local employment laws. You focus on managing your team, while the EOR keeps you compliant.

3. Geographic coverage

A PEO only supports employees in the state or country where your company is legally registered. This makes it best for managing local teams and streamlining HR services under your existing legal structure.

An EOR eliminates those boundaries. Using its existing network of local entities, it enables you to hire employees in countries where you don’t yet have a legal presence. It's the go-to option for companies expanding internationally. 

4. Cost structure

A PEO typically charges lower initial service fees but may add separate costs for benefits, insurance, and compliance consulting. Over time, these add-ons can increase total expenses. 

An EOR offers a flat, all-inclusive fee that covers payroll, benefits, and compensation. For global teams, that predictability simplifies budgeting and accelerates scaling.

PEO vs. EOR: Pros and cons

Both PEOs and EORs can influence how your company hires, manages, and supports its team. Here are the pros and cons of each so you can decide on the ideal approach for your organization. 

PEO pros

• Access to pooled benefits for U.S. teams: Many PEOs provide large-group health plans, retirement options, and workers' compensation, helping smaller organizations reduce costs.
• Integration with HR operations: A PEO extends your internal HR team by managing payroll and benefits while you stay in charge of daily operations. 
• Cost-effectiveness for domestic growth: For companies opening in the U.S. or a single region, a PEO can be more affordable than hiring a full in-house HR staff and legal counsel. 

PEO cons

• Requirement for a legal entity: Your company must be registered in the region where it operates, as PEOs can't employ team members on your behalf.
• Shared compliance liability: In a co-employment arrangement, your company still bears the responsibility for compliance and employment-related risks. 
• Limited geographic reach: PEOs support employees only in regions where your business is established, making cross-border expansion more complex.

EOR pros

• No entity needed: An EOR employs team members through its own local entities, removing the need for you to set up a subsidiary. 
• Faster global hiring: Onboard talent within days rather than months, as the EOR handles contracts and compliance in each country.
• Full compliance responsibility: An EOR takes on the legal and administrative risk tied to local labor laws and tax obligations. 

EOR cons

• Limited control over HR policies and benefits: EORs generally standardize benefit offerings and may restrict customization for individual markets. 
• Higher per-employee costs in some regions: Flat, all-inclusive pricing can exceed a domestic PEO’s costs in countries with expensive statutory benefits. 
• Potential overlap with internal HR tools: Some EOR platforms may overlap with your existing HR systems, which can create extra coordination between teams.

PEO vs. EOR: Which is right for your business?

Choosing between a PEO and an EOR depends on your company’s structure and risk tolerance. Use these questions as a framework to guide your decision:

• Do you already have a legal entity where you plan to hire? If yes, a PEO could align better since it builds on your existing registration. If not, an EOR is the more practical route because it hires through its own local entities and handles compliance directly. 
• Are you expanding within one country or across multiple markets? PEO services typically support domestic and regional teams, making them less suitable for international expansion. By contrast, EORs enable cross-border hiring without setting up new entities and navigating local labor laws. 
• How much liability are you willing to take on? Under a PEO, you share compliance risk as a co-employer. But EORs take on full legal and administrative responsibility, reducing your exposure in unfamiliar legal environments. 
• Is speed to market a priority? Building a legal entity and setting up payroll can take months. EORs already have the infrastructure in place, allowing you to hire and onboard employees quickly.
• What level of HR support do you need? PEOs offer broad, integrated HR services—like benefits management, employee training, and compliance consulting—making them ideal for scaling within a country. EORs focus on compliant hiring and payroll abroad, helping you expand without entity setup.
