Abstract: A computer system and associated methods for implementing an online freight services marketplace. Freight service offerings posted to the marketplace by carriers are matched to freight service requests from shippers. Compound service offerings are formed from freight service offerings having service parameters (lane, space, transit time, availability, price, and status) that accommodate load parameters (origin, destination, size, and weight) of the freight service request. Compound service offerings selected by the shipper are provisioned and reserved for subsequent dispatch. Role-based access controls within the marketplace restrict visibility of confidential information, such as carrier pricing and shipper identity. Automatic freight transaction facilitation includes shipper payment processing and shipping document generation. Status tracking capability may be augmented with alert messaging and/or in-transit re-planning to minimize the impact of common issues that threaten to defeat a shipment in progress.
