Abstract: Systems and methods for a network-based sales system with customizable user interfaces are described. The system generates first and second sales interfaces based on customization commands and communicates the sales interfaces, over a network, through respective member sites to first and second users. The system further receives first and second requests to view a listing of an item that is presented in an offer for sale via the first and second sales interfaces, retrieves a record from a central database system that is changed responsive to a sale of the item that is presented in the first and second sales listings, modifies an object model representation of a central database system based on the retrieval of the record that is changed and regenerates the first and second sales interfaces responsive to the modification of the object model representation.

Abstract: A sales system for coupling to a communications network. The sales system includes a sales interface at a first network address that includes a set of categorized interface elements. In addition the sales system includes another sales interface at a different network address that includes a second set of categorized interface elements. Finally the system includes a sales server at a third network address that may be used to operate both sales interfaces to provide an impression that the first and second sales interfaces are being operated by different entities. The sales server includes a categorization interface that responds to user input to define both sets of categorized interface elements. The categorized interface elements respectively include a plurality of specification elements.

Abstract: A sales system is disclosed for coupling to a communications network. The sales system includes a first sales interface at a first network address, with the first sales interface including a first set of user interface elements. The system also includes a second sales interface at a second network address, with the second sales interface including a second set of user interface elements. A customization interface is responsive to user input to define the first and second sets of user interface elements.
