Three different models for hiring internationally get conflated constantly. Here's the actual difference, and which fits which situation.
These three models get used interchangeably in vendor marketing but are structurally different, with different legal and cost implications.
The EOR is the legal employer for compliance purposes in a country where you have no entity. Fast to set up (days to weeks), priced per employee per month, no entity required. Best for low headcount or testing a new market.
A co-employment model, typically used where you already have a legal entity (most common domestically, e.g., US state-to-state) — the PEO handles payroll, benefits, and HR compliance administration while you remain the legal employer of record in substance. Different regulatory model from EOR; don't assume the terms are interchangeable internationally.
You set up and own a local subsidiary. Highest upfront cost and longest timeline (often months), but lowest long-term per-employee cost at scale, and full control over benefits, equity plans, and local employer branding.
