3PL (Third-Party Logistics) Billing System:
A software application that captures billable services by a third-party logistics company, such storage fees, pallet handling activities and more. It then applies contractual rates to those services, and either sends invoices directly to the 3PL’s clients or sends the charges to the 3PL’s accounting system.
If the billing system and the WMS are from the same vendor, the billable services should be automatically captured without any need for integration. In some cases, non-3PLs find value in a billing system if they need to charge separate company business units in a shared services environment.
