Abstract: A method and apparatus for promoting taxpayer compliance. A computer-implemented data mining system mines taxpayer data to identify taxpayer profiles for taxpayer compliance issues. A computer-implemented decision management system assigns the identified taxpayer profiles into groups based on characteristics of the taxpayer profiles. A computer-implemented case management system implements different treatments to different groups, to improve taxpayer compliance.

Abstract: A method for customer promotion includes sequentially processing each of a plurality of items in a customer order. The price of each item is accumulated after processing. A marginal discount associated with each item processed is generated. This marginal discount is generated in response to a signal that indicates the accumulated price exceeds a predetermined threshold. Unapplied marginal discounts are accumulated for application to the customer order. A discount is applied to the customer order in response to a signal that is generated that indicates the accumulated discounts exceeds a predetermined minimum.
