3PL (third-party logistics) is logistics outsourced to an external provider that handles warehousing, picking, packing, shipping and returns while the store focuses on sales.

What is the difference between 3PL and 4PL?

A 3PL provider does the logistics work itself: warehouse, people and systems. A 4PL company manages the whole supply chain and coordinates several suppliers, but subcontracts the warehouse work. Completio operates as a 3PL provider.

How much does a 3PL provider cost?

The price is made up of receiving, storage, picking, packing, shipping and returns, and depends on order volume, product type and scope. See fulfillment pricing for the cost drivers; we'll quote your store within 24 hours.

What size of store do you work with?

We work with startups, small and mid-sized stores and large companies. The cooperation model is flexible and grows with your sales; we agree the scope when we prepare the quote.

Guide

What is 3PL and what does a 3PL provider do?

3PL (third-party logistics) means outsourcing logistics to an external company. A 3PL provider takes over warehousing and shipping, while the store focuses on sales, marketing and product. In e-commerce, 3PL usually means fulfillment: handling orders from the shelf to the customer's door.

A 3PL provider does the physical work: it runs the warehouse, people, machines and WMS. That is the difference from 4PL, where an external company manages the whole supply chain but subcontracts the warehouse work.
