4PL, or Fourth Party Logistics, is a modern approach to managing supply chains where a company acts as the main coordinator of all logistics activities. Think of a 4PL as a "logistics general contractor" who oversees and manages other logistics providers (like shipping companies, warehouses, and 3PLs) on behalf of their client. They don't typically own trucks or warehouses themselves - instead, they use technology and expertise to coordinate different service providers, optimize operations, and provide end-to-end supply chain solutions. This is different from 3PLs (Third Party Logistics) who usually directly provide specific services like warehousing or transportation.
