Abstract: An automated pricing system for calculating pricing for items and item orders has, a sever node connected to a data network for serving pricing information; a pricing application running on the server node for calculating the pricing information served; and a data repository accessible to the server node for storing at least one pricing data model and rules for manipulating the model. The server node receives requests for pricing, accesses rules created for pricing factors used in at least one pricing sequence to price an item or items of the request and uses the pricing application to calculate the correct pricing results including order sub totals and order total amounts for the request based on sorting and/or conflict resolution of the rules accessed for each factor.
