Doing Business with Winnebago County

The County is always seeking qualified vendors to provide products, equipment and services, at the most favorable prices, as this will ensure that the County's taxpayers are receiving maximum value for tax dollars.  Purchasing assists all County departments with their purchasing needs to ensure conformance with both the Illinois Compiled Statutes and the Winnebago County Purchasing Ordinance. With a few exceptions, the Purchasing Ordinance requires free and open competitive bidding for all for goods, services and construction exceeding $30,000 (or $50,000 for professional services). This type of procurement is called "Competitive Bidding” which is publicly advertised, and solicitations are issued as formal Invitations to Bid (IFB), Requests for Proposals (RFP), Requests for Quotes and Requests for Qualifications (RFQ). Current Bid opportunities can be found at Open Bids, Quotes & RFP’s.

Requirements of less than $30,000 are made in accordance with established procedures for small dollar purchases.  Small dollar purchases are made at the department level by soliciting vendors for quotes via e-procurement, telephone or email.  Please see our Terms & Conditions for more on doing business with Winnebago County.
