Abstract: A network computer system operates to store a plurality of records, where the plurality of records identify (i) a plurality of shipment orders, and (ii) a plurality of freight operators. The record for each shipment order identifies a set of shipment parameters for that shipment order, and the record for each freight operators identifies availability information for the freight operator. One or more matching processes are performed using the plurality of records, to match shipment orders and freight operators. The network computer system generates a preview panel to display matchings as between shipment orders of the plurality of shipments orders, and available freight operators of the plurality of freight operators.
