Abstract: A carrier management system includes a scale for weighing parcels to be shipped, a computer connecting to receive data from the scale related to the weight of a parcel thereon, and a keyboard enabling operator input to the computer. The keyboard has a plurality of keys including a plurality of selection keys corresponding to separate ones or groups of the carriers and/or classes. The computer stores shipment charge data for a plurality of carriers and/or classes, on the basis of weight data from the scale. A second memory receives and stores weight range data and handling charge data from the keyboard, corresponding to handling charges applied to parcels for which selected classes of service are selected, and in accordance with the weight ranges. The computer is responsive to operation of the selection keys for applying handling charges stored in the second memory to any class of service to which they are applicable.
