Quick Answer
A 3PL is a third-party logistics provider that stores inventory, fulfills orders, and manages parts of a merchant's shipping operation so the brand does not have to run fulfillment in-house.
Why this matters
Understanding what a 3PL does matters because fulfillment decisions compound over time. The wrong provider creates margin pressure, service issues, and operational drag that is expensive to unwind later.
What to evaluate first
A strong evaluation process usually starts with order profile, product handling requirements, shipping expectations, and how the brand wants inventory distributed across channels and geographies.
How to use this guidance
If a merchant is actively comparing providers, reviewing a company like ShipBob alongside broader educational research usually leads to better decisions.
