Doing Business/Vendor Registration
County agencies spend millions of dollars annually providing necessary services to the citizens of Maricopa County. It is our goal to ensure that these expenditures achieve maximum value for money by ensuring efficient practices, transparent processes, and fair and open competition. We work with agencies and suppliers to improve collaboration, and sustainability while promoting innovation and value. Under the Chief Procurement Officer, the Office of Procurement Services is responsible for all County contracts for goods, services, and construction.
As stewards of the public trust, we observe the highest standards of integrity, honesty and fairness and discharge our duties and responsibilities regardless of personal considerations avoiding circumstances that create an appearance of impropriety. We will protect the county's assets and its reputation through professional and personal conduct that is above reproach. We expect the same from our partners.

Maricopa County encourages maximum competition and promotes open fair processes. In order to receive notification of county solicitations, vendors must register in the County's e-procurement platform, Periscope S2G (formerly known as BidSync) at https://prod.bidsync.com/maricopa-county. While Periscope/BidSync does offer additional subscription services, the only thing required to do business with the County is the Free Registration. During registration, be sure to select appropriate commodity codes and notification preferences. Your Periscope/BidSync registration allows you access to participate in solicitation opportunities from multiple government agencies.
If your business provides construction, architectural, engineering, or related professional services, please complete the appropriate Maricopa County Contract Services qualification for each discipline that you wish to be considered for.
