What Is 4PL?
Defining Fourth-Party Logistics
4PL stands for Fourth-Party Logistics. It is a business model where a company outsources the management and optimization of its entire supply chain to a single, specialized provider. The 4PL provider acts as a strategic partner, managing multiple 3PL providers and other logistics vendors on behalf of the client.
