What Is a 3PL?
Learn what a 3PL is, how it works, and why growing DTC brands use third-party logistics to scale efficiently.

Choosing a 3PL comes down to three questions, asked in order. What would a 3PL do for you? How does it compare with the other ways to ship your orders, and what will it cost? Which provider fits your products, your volume and the way you like to work? The guides below follow that order. Start wherever you are.
Three common situations, and the page that helps first.
Start with what a 3PL is and the signs it is time to stop packing orders yourself. Then put real numbers side by side in 3PL vs in-house fulfillment.
Read the signs it is time to switch, then how to compare 3PLs side by side and how to switch without missing orders. If the problem is that nobody answers when it is urgent, switching to a 3PL with someone on site is written for you.
Check every quote against the 3PL checklist and red flags and the contract terms to read before you sign. To make the quotes comparable, send every provider the same data: what to send a 3PL for an accurate quote.
