Vendor Registration

Maricopa County encourages maximum competition and promotes open fair processes. We encourage all interested suppliers to register to do business with the County's e-procurement application, Bidsync in order to participate in procurement opportunities at Maricopa County. Registration is free.
Your Bidsync registration allows you access to participate in solicitation opportunities from multiple government agencies. Be sure to select appropriate commodity codes and notification preferences.

If you have not received payment from Maricopa County before, once you receive a new award, a payee ID number will be assigned to your business. Use this number along with your tax id number to complete your Maricopa Payee Registration in order to receive payment. Bidsync offers optional subscription services in addition to the free registration that is required for Maricopa County.
