Transportation management system (TMS)
A software platform used to plan, execute, and optimize the physical movement of goods. A modern TMS unifies procurement, planning, tendering, tracking, and settlement in one place.
Managed transportation
An outsourced 4PL service in which a provider manages a shipper's freight operations end-to-end — covering procurement, planning, execution, and analytics — on top of an underlying TMS.
Freight procurement
The process of sourcing, negotiating, and contracting with carriers for shipping capacity, typically run annually or quarterly via RFPs and mini-bids across hundreds or thousands of lanes.
RFP (request for proposal)
A formal procurement process where shippers solicit carrier bids on specific lanes, equipment types, and service requirements. Modern TMS platforms run RFPs digitally with structured bid data.
Lane
A specific origin-destination pair on which freight regularly moves. Lane-level pricing, performance, and carrier assignments are the fundamental unit of managed transportation strategy.
Tender
A formal offer of a specific load to a contracted carrier at the contracted rate. The carrier accepts or declines based on capacity. Tender acceptance rate is a core measure of carrier health.
Execution
The day-to-day operational running of freight — tendering loads, tracking shipments, managing exceptions, and confirming delivery. The "doing" part of transportation management.
Settlement
The financial close-out of a shipment, including invoice receipt, audit against contracted rates and accessorials, dispute resolution, and payment to the carrier.
