Both let you offload payroll and benefits admin - but only one takes on the full employer role, so you can hire where you aren't set up. Here's how to decide.

The core difference comes down to who the legal employer is. An Employer of Record (EoR) becomes the sole legal employer of your workers and uses its own registrations, insurance, and entities, which is why it's what you use to hire in a US state where you aren't registered as an employer, or a country where you have no entity. A Professional Employer Organization (PEO) uses a co-employment model: your company stays an employer, so abroad you need your own local entity, and in the US you may still need your own state registrations depending on the state. It shares employer responsibilities with you rather than taking them on fully. Put simply: use an EoR to hire where you aren't set up or across borders; use a PEO to outsource HR where you already are.
An Employer of Record is a third party that becomes the full, sole legal employer of your workers on paper - handling payroll, taxes, benefits, and compliance - without requiring you to have your own entity or employer registrations in the location where you're hiring.
A Professional Employer Organization is a firm that enters into a co-employment relationship with your company to administer HR, payroll, and benefits - but your company stays an employer: abroad you need your own local entity, in the US you may still need your own state registrations, and you share employer responsibilities.
| Employer of Record | PEO | |
|---|---|---|
| Legal employer | The EoR is the sole legal employer | Co-employment - shared between you and the PEO |
| Your own entity or state registrations required? | No - the EoR's registrations cover your hire | Often - you stay an employer |
| Employment & liability model | EoR assumes full employer liability | Liability shared under co-employment |
| Sources or recruits talent? | Can - WorkGenius sources and matches talent | No - you bring your own workforce |
| Geographic fit | All 50 states and 100+ countries | Primarily US-domestic |
| Who owns compliance | The EoR, end to end | Shared with you as co-employer |
| Payroll & taxes | Run under the EoR's entity and tax IDs | Administered by the PEO under co-employment |
| Benefits | Provided through the EoR | Pooled through the PEO's plans |
| Typical use case | New states & international hiring | Outsource HR where you're already set up |
The bottom line: Use an Employer of Record to hire and stay compliant where you aren't set up as an employer or across borders; use a PEO to outsource HR administration where you already are.
