Abstract: A system and method (100, 310, 510) of inventory tracking and custom ordering over a computer network (316). The system includes a multimedia user interface (318) delivered over the computer network to a user, and a configuration and pricing database (324) storing product pricing data according to user-entered product configuration. An inventory database (322) stores product availability data in inventory of retail sales facilities, in-transit from product manufacturing facilities to the retail sales facilities, in-plant at the product manufacturing facilities, and on a ordering bank at the product manufacturing facilities. The user is able to search, via the multimedia user interface (318), the inventory database (322) for the user-entered product configuration and receive pricing data and product availability data. A sales processor (332) is operable to receive, via the multimedia user interface (318), user reservation of an available product determined by the search.
