Third-party logistics (3PL) involves using external individuals or organizations to execute logistics activities that have traditionally been performed within an organization itself. If, for example, a company decides to export its product, it may hire a person or organization to help with distribution logistics. Today, there is a movement toward building fourth-party logistics (4PL), which integrates 3PL competencies and other organizations to design, build, and run comprehensive supply chain solutions. A 4PL general contractor would manage other 3PLs, truckers, forwarders, custom house agents, and others, essentially taking responsibility of a complete process for the customer.
