3GTMS, branded on its website as Descartes 3G TMS, is a cloud-based transportation management system for shippers, third-party logistics providers and freight brokers. It supports planning, rating, consolidation and routing of domestic over-the-road shipments, including truckload, less-than-truckload (LTL) and parcel, across the full shipment lifecycle. Functions include carrier management, shipment visibility, settlement and invoicing, reporting and analytics, and AI-supported automation. The system is delivered as cloud software and connects to the Descartes Global Logistics Network.
3GTMS is headquartered in Columbus, Ohio, in the United States. In March 2025 it was acquired by Descartes Systems Group, a Canadian company listed on the TSX and Nasdaq, so the ultimate parent is in Canada. The website does not state where customer data is hosted. The product is not open source.
