Ryder System's transportation management business tenders freight to contracted motor carriers through EDI, governed by the Ryder LMS (Logistics Management System) implementation guides. Ryder sends 204 load tenders; carriers return 997 acknowledgments and 990 accept or reject responses, then send 214 shipment statuses and 210 freight invoices. Ryder publishes the X12 version 004010 specification for each transaction set on its carrier resources page.

Testing: Ryder defines compliance through its implementation guides rather than a formal certification program. A 997 is required within one hour of the 204, and a 990 accepting or rejecting each tender must arrive by the must-respond-by date and time sent in the 204 or the load may be reassigned. Ryder returns 997s within one hour for inbound 990s and within 24 hours for 210 invoices, and requires carriers to receive and reconcile all 997s.

Timeline: Ryder publishes no setup timeline. Scope is small (four core transaction sets plus 997s), so duration mostly reflects the carrier's own EDI readiness and scheduling with the Ryder EDI group; the acknowledgment and response-time rules apply from the first production tender.
