PEO or EOR: which do we need?
The short answer
A PEO co-employs your existing workforce in places where you already have a legal entity — you keep direction and control, and the PEO becomes employer of record for tax and benefit purposes. An EOR fully employs the worker on your behalf, and exists for the case where you have no entity in that state or country. Use a PEO to improve how you employ people you already employ; use an EOR to employ someone where you legally cannot.
The distinction in one line
A PEO shares employment with you. An EOR takes it entirely. That is not a difference in degree, and choosing on the basis of which sounds more comprehensive produces expensive mistakes in both directions.
What an EOR is actually for
The defining use case is entity absence. You want to hire someone in a state or country where you have no legal presence, and standing one up — registration, tax accounts, statutory filings, sometimes a local director — would cost more than the hire returns. The EOR already has that entity. It employs the person under its own name and invoices you.
That makes it excellent for a small number of people in many places, for testing a market before committing, and for international hiring where the entity cost is genuinely prohibitive. It makes it poor value for a large concentrated workforce, where per-head EOR pricing is usually more expensive than simply registering.
What a PEO is actually for
Improving the terms and administration of a workforce you already have, in places where you already operate. Pooled benefit purchasing, absorbed administration, a compliance floor. It presumes you have entities and are employing people; it makes that better rather than making it possible.
The mistake in each direction
Using an EOR for a domestic workforce you could employ directly means paying a per-head premium indefinitely for a problem you could solve once with a registration. It also puts a third party between you and your employees in ways that complicate equity, culture and long-tenured relationships.
Expecting a PEO to solve entity absence is the reverse error. A PEO does not give you the ability to employ where you have no presence — some will decline to onboard employees in states where you are not registered, precisely because the arrangement assumes you are.
Using both
It is a legitimate combination and reasonably common: a PEO for the domestic core, an EOR for a handful of people in places where registering is not yet justified. What it costs is complexity — two sets of benefits, two employment experiences, and an internal answer needed for why a colleague’s arrangement looks different.
Worth deciding in advance at what point an EOR relationship converts to direct employment. Most companies discover they have drifted past that threshold rather than crossing it deliberately.
| PEO | EOR | |
|---|---|---|
| You need a legal entity there | Yes | No |
| Employment relationship | Shared with you | Entirely the EOR |
| Direction and control | Yours | Yours in practice, EOR is employer |
| Typical population | Your whole workforce | A few people per location |
| Cost shape | Fee across the workforce | Per head, premium |
| Main purpose | Better terms and less admin | Employing where you cannot |
| International | Rare | The common use |
