- A transportation management system (TMS) is part of supply chain management (SCM) centered on transportation logistics. A TMS enables interactions between an order management system (OMS) and distribution center (DC) or a warehouse. TMS is used to coordinate and control hundreds of freight shipments from pickup to delivery. TMS is a web based tool, on which a customer has to log in to his/her account. With TMS - customers are able to easily and quickly quote shipments. After the customer logs in, he is requested to provide two zip codes for pickup and delivery, freight class and total shipment weight. This input then allows the TMS to provide the customer with options of carrier options, pricing options, and even varying transit times. Using a TMS, a customer can build his shipments and BOLs, schedule the pickup with the designated carrier and even track the shipment until delivery. Being an online helping hand - the TMS as a machine intelligence saves the data and helps the customer the next time, taking away the time to again follow the procedures.
