What is 4PL
Independent: A 4PL provider is not tied down to any assets (e.g. warehouses, transportation, technology, etc.) and the fixed costs they involve. Therefore, a 4PL is completely free of bias during the provision of services, choosing the best-in-class resources (often 3PLs, 2PLs, etc.) to operate specific segments of the supply chain.
Integrator: A 4PL is a single point of contact who handles everything in the supply chain suppliers, service providers, customs, tax rules and regulations, etc. This way, the entire supply chain operation is addressed, giving the 4PL service provider the ability to look at and optimise all aspects of the supply chain.
