Third-Party Logistics

Third-Party Logistics (3PL) is a company that stores a brand's inventory and picks, packs, and ships its orders under contract, usually charging per order, per pick, and per unit of storage.

Why it matters for ecommerce brands

Most US DTC brands outsource fulfillment to a 3PL once they pass a few hundred orders a day. The contract terms (minimums, storage units, receiving fees, SLAs) shape your cost per order more than the headline pick fee.

Formula and example

Typical invoice lines: receiving (per hour or per unit) + storage (per pallet, bin, or cubic foot per month) + pick and pack (per order + per additional item) + packaging + postage.

Common questions

When should an ecommerce brand switch to a 3PL?
Many brands move to a 3PL when packing orders in-house takes too much time or space, or when they need faster shipping nationwide. Compare the 3PL's full cost per order, including storage, receiving, and minimums, with in-house costs.
