Abstract: Systems and methods here may be used for conducting computer network transactions, via at a server computer in communication with a network and a database. Such examples may include receiving merchant information from merchant/bidders, categorizing the received merchant information, storing the merchant information and the associated category in the database, receiving a need from a user/buyer computer, identifying a category that the received need fits into based on the categories of merchant information, posting the received need information so the merchants identified for that category may access the posted need information and allowing the merchant/bidders to bid on the received need.
