Abstract: The present invention relates to a method and system for establishing freight rates or shipping charges associated with shipping goods in the trucking industry. More specifically, the present invention relates to a method for establishing the appropriate charge for shipping a partial load of goods when those goods are combined with other goods on the single truckload. The resulting system provides a shared cost/split invoicing system for combined less-then-truckload (LTL) shipments that: (i) is simple to implement, (ii) reduces the possibilities for human error, and (iii) fairly reflects each customer's fair and proportional cost to transport its goods from its selected point of origin to its selected destination.
