3PL (third-party logistics provider)

The term is broad by design. A 3PL might be:

• A freight brokerage that calls itself a 3PL because it also offers managed transportation.
• A warehouse operator storing and shipping a customer’s inventory, with trucking arranged by its brokerage arm.
• A managed transportation provider that runs a shipper’s TMS, tenders its loads, and audits its freight bills for a fee.
• An asset-based carrier with a brokerage and a warehouse division.

What they share is that the shipper has outsourced a function and expects the 3PL to own the outcome, including the problems: the late load, the damaged pallet, the invoice that does not match. Most of the software work in a 3PL is about those exceptions, and most of its labor is the paperwork around them.

For a shipper, the practical questions are what the 3PL does with its own people and assets versus what it brokers out, and who is responsible when a brokered carrier fails. For a broker, the word matters mostly in sales: a prospect that describes itself as using a 3PL is buying a service, not a truck, and the conversation is about reliability and reporting before it is about rate.
