Abstract: A computer system and method is disclosed for pre-qualifying vendors for buyers and/or industries using vendor criteria information associated with buyers and/or industries and vendor qualification information associated with vendors. Vendors and buyers enter the vendor qualification information and vendor criteria information, respectively, into a database in a hierarchical and relational manner. The computer system compares entered vendor qualification information to stored vendor criteria information to pre-qualify vendors for buyers and/or industries. The computer system further monitors the stored vendor qualification information and requests updated vendor qualification information from the vendors to maintain vendor qualification on a per industry and/or per buyer basis.
