Fourth-Party Logistics (4PL)
A supply chain integrator that manages and coordinates a company's entire logistics operation, including oversight of multiple 3PLs, carriers, and technology providers. Unlike a 3PL that provides specific logistics services, a 4PL acts as a single point of accountability for the entire supply chain, designing and managing the logistics strategy on behalf of the client. 4PLs are typically used by large enterprises with complex, multi-modal, multi-geography supply chains.
Real-World Example
A multinational consumer goods company hires a 4PL to manage their North American supply chain, overseeing 6 different 3PL warehouses, 50+ carriers, and 3 TMS platforms under a single integrated strategy.
