ERP, WMS, and TMS boundaries
ERP, WMS, and TMS are useful labels for enterprise administration, warehouse execution, and transportation management. Their exact boundaries depend on the installed products and business design. Clear responsibility matters more than the acronym.
How it works in practice
List important records and events: items, orders, receipts, adjustments, shipments, freight plans, and invoices. For each, define the authoritative source, permitted changes, receiving systems, and the confirmation that closes the handoff.
A warehouse example
The ERP may send a sales order; the WMS confirms the quantity actually shipped; a TMS coordinates the carrier movement. A partial shipment must retain consistent references across these records.
Illustrative scenario, not a claim about a client engagement.
What to watch for
Two systems can disagree even when every message was delivered successfully. Different status meanings, timing, and units can create business discrepancies without a technical connection failure.
A useful question
Which system owns a shipment change after warehouse work has started?
