Third party logistics providers (3PL) offer a variety of services, but the primary function of these organizations can be summarized as providing transportation, warehousing, and management of inventory for another company. Some companies handle inventory on consignment. Consignment stock is often defined as inventory owned by one party (in this case the “Supplier”), but held by another (the “3PL”). This risk rests with the first party, and do not get paid until the goods are sold (in this case the third player, the manufacturing “Company”).
