A computer-implemented method includes receiving a plurality of attribute headings for a product and storing the product and the associated attribute headings as part of a negotiation. A request for products associated with the negotiation is received and in response, a user interface listing at least one of the attribute headings for the product and providing controls for entering an attribute value for the listed at least one attribute heading is generated and transmitted. An attribute value for the listed attribute heading is received as part of a bid during the negotiation and is stored. An indication that the negotiation is complete is received and in response, the attribute value for the listed attribute heading is locked. An instruction to create a new item in an item database is received and in response to the received instruction, a request is sent to retrieve the locked attribute value and store the locked attribute value in an item database used by retail systems to acquire information about products for sale in a retail enterprise.
