Abstract: A freight calculation system includes a seller client, a buyer client, and a platform coupled to the seller client and the buyer client using a communication network. The seller client generates freight data and communicates it using a communication network. The buyer client communicates a delivery request for a load using the communication network. The delivery request specifies one of a number of delivery containers, an origination location, and a destination location. The platform receives and stores the freight data and determines a delivery cost for the load using the freight data, the specified delivery container, the origination location, and the destination location.
