PEO Comparisons
PEO vs. EOR: What's the Difference?
A PEO co-employs your existing US workforce, sharing HR responsibilities while you retain control. An EOR is the sole legal employer, typically used for international hiring. Understanding the difference is critical before choosing an HR outsourcing model.
Talk to a PEO ExpertThe Core Distinction
The fundamental difference between a PEO and an EOR comes down to one question: who is the legal employer of the workers?
In a PEO arrangement, both the PEO and the client business are co-employers. The client business retains its identity as the employer — employees are hired by the client, work under the client's direction, and identify with the client's brand. The PEO handles the administrative employer responsibilities: payroll, tax filings, benefits, and compliance. The co-employment relationship is defined in a Client Service Agreement.
In an EOR arrangement, the EOR is the sole legal employer of the workers. The client business has no direct employment relationship with the workers — they are employed by the EOR and contracted to the client. This structure is most common in international hiring scenarios, where a company wants to hire workers in a country where it has no legal entity. The EOR establishes the local entity, hires the workers, and manages all local employment law compliance.
For US-based small and mid-sized businesses with an existing domestic workforce, a PEO is almost always the more appropriate choice. The co-employment model preserves the client's employer identity and culture while delivering the cost and compliance benefits of outsourced HR. EORs are better suited for international expansion or niche compliance scenarios.

Frequently Asked Questions
What is the difference between a PEO and an EOR?
A PEO (Professional Employer Organization) enters a co-employment arrangement with a client business, sharing employer responsibilities. The client retains control over hiring, firing, and operations. An EOR (Employer of Record) is the sole legal employer of the workers — the client has no direct employment relationship with the workers. EORs are typically used for international hiring or situations where the client has no legal entity in a jurisdiction.
When should I use a PEO instead of an EOR?
Use a PEO when you want to retain control over your workforce while outsourcing HR administration. PEOs are ideal for US-based businesses with existing employees who want to reduce HR costs, access better benefits, and manage compliance. Use an EOR when you need to hire workers in a country or state where you have no legal entity, or when you want to test a new market without establishing a local entity.
Is a PEO or EOR better for a US small business?
For US small businesses with an existing workforce, a PEO is almost always the better choice. PEOs provide co-employment benefits — group health insurance rates, workers' comp at scale, HR compliance — while allowing the business to maintain its employer identity and culture. EORs are better suited for international expansion or specific compliance scenarios where the client cannot or does not want to be the employer of record.
