VENDEX is the City’s automated ‘Vendor Information Exchange System’ and is one of the resources the City uses to make well-informed decisions when selecting a vendor. . Prospective vendors are required to complete VENDEX Forms (Vendor and Principal Questionnaires), which elicit background information from vendors who wish to bid on all contracts and subcontracts valued at $100,000 or more, sole source contracts valued at $10,000 or more and/or whose aggregate business with the City in the preceding twelve (12) months totals $100,000 or more. You may obtain VENDEX forms here.
