Abstract: The present invention provides systems, methods, and computer program products for maintaining a product inventory. The present invention provides various control information and marketing control information that allows a user/seller to define the product, as well as the inventory and marketing controls to use with the product. In addition, the present invention provides different calculator and adjustor modules that each implement different control and inventory methodologies. The user inputs the selected control and marketing control information for a product, and selects the proper calculator and adjustor module to be used with the product. In operation, the present invention uses the controls and marketing controls input by the user, as well as the selected calculator and adjustor module to control inventory for the product. The present invention thereby allows a user to define the product and select proper controls for the product, without requiring the user to create specialized software.
