3G TMS is transportation management software for shippers, 3PLs, and 4PLs to plan, execute, and settle freight with unified visibility and control.
3G TMS, part of the Descartes Global Logistics Network from Descartes Systems Group, is a unified transportation management platform for shippers, 3PLs, and 4PLs. It covers multimodal planning, rating, and execution so teams can source and optimize loads across truckload, LTL, parcel, and drayage from one system.
The platform includes carrier management (onboarding, compliance, and performance tracking), real-time shipment visibility with proactive alerts, and collaboration tools that keep carriers, customers, and internal teams aligned. Settlement and invoicing workflows streamline freight audit and payment, while AI-assisted automation targets exception handling to cut manual work.
3G TMS serves industries including food & beverage, retail, building supplies, distribution, agriculture, transportation & logistics, and manufacturing. Reporting and analytics give operations teams real-time visibility into cost, service levels, and efficiency across their freight network.
