Third-party logistics (3PL) involves outsourcing elements of distribution, warehousing, and fulfillment services to specialized third-party businesses. 3PL providers offer integrated operations and customized solutions across warehousing and transportation to meet customer demands. Services may extend beyond logistics to include value-added supply chain functions. There are different types of 3PL providers categorized by the level and customization of services offered, from basic providers to customer-oriented developers that take over entire customer logistics functions. Outsourcing to 3PL can provide advantages like cost savings, low capital needs, and flexibility, but also results in some loss of control for the customer.
