Open TMS
What it is
Open TMS is a free, open-source transportation management system covering logistics from order intake through delivery. Orders can enter by CSV, EDI 850, REST API, or manual entry, then move through shipment tracking, lane matching, and multi-stop routing. Carrier workflows include broadcast and waterfall tenders, a bidding portal, and EDI 204/990 tendering. Its EDI hub handles X12 transactions such as 850, 855, 856, 204, 990, 997, 214, 210, 810, and 820 through SFTP or HTTP. Tracking integrations are described for FedEx, UPS, and DHL APIs. GPS and sensor telemetry can support traffic-aware ETA monitoring with TomTom, HERE, or self-hosted Valhalla. Warehouse functions cover receiving, putaway, picking, packing, load planning, inventory, and returns. A scan-first progressive web app supports barcode work with Zebra and Honeywell RF guns. Deployment uses Docker Compose on cloud or self-hosted infrastructure.
