Unless otherwise required by law, all goods and services shall be procured by issuing competitive sealed bids or proposals. - Formal Requests for Proposals (RFP’s), Invitations for Bids (IFB’s) and Requests for Qualifications (RFQ’s) are used for the purchase of goods and services in excess of $50,000 and construction in excess of $100,000. Informal quotes are used for goods and services $50,000 or less. The County Board of Supervisors approves all contracts for goods and services in excess of $250,000. - Formal solicitations require posting of a public notice and submission of a sealed bid or proposal. Although a sealed bid technique is not used, all informal quotations greater than $10,000 are made on a competitive basis, soliciting quotes from at least 3 vendors whenever possible. The Maricopa County Procurement Code exempts small purchases of $10,000 or less from the competitive solicitation process. Procurement requirements shall not be artificially divided so as to constitute a small purchase.
