How does the City of Naperville purchase goods and services?

The Procurement Services Team contracts or buys equipment and services related to the operation and maintenance of all City departments and their facilities in accordance with the City’s Procurement Ordinance and the statues of the State of Illinois.

  • Purchases under $25,000 require a minimum of three quotations with award recommended to the lowest responsive, responsible bidder.
  • Purchases $25,000 or greater:
    • Formal Bid Process: All purchase orders of contracts of whatever nature, except as otherwise directed by the City Council will be subject to the open competitive bidding process for amounts in excess of ($25,000). The award of the bid shall be to the lowest responsive, responsible bidder, unless otherwise directed by City Council to be in the best interest of the City of Naperville.
    • Request for Proposal/Request for Qualifications: The Request for Proposal (RFP) is the document used to secure offers when the procurement is of an estimated value of $25,000 or more and when competitive sealed bidding is not practical or advantageous. In some instances, a RFP is used when precise specifications cannot be developed and price is not the major factor to be evaluated by the Procurement Services Team. The Request for Qualifications (RFQ) is the document used to obtain a statement of qualifications from bidders before the final bid document is issued. After eliminating respondents who do not meet the criteria of the RFQ, the bid document is issued to those certified as qualified.

Advertising of Bids shall include a general description of the articles, materials and/or services to be purchased or sold, and shall state the time and place of bid opening.

  • DemandStar: All bids/RFP/RFQ are posted on DemandStar.com, the City’s online bidding service provider. Visit DemandStar to view what is currently advertised and for more information about how to subscribe.
  • Newspaper: A legal notice inviting vendors to submit bid proposals shall be published in the legal section of the Wednesday Chicago Tribune at least (10) days prior to the bid opening date for all formal contracts over twenty-five thousand dollars ($25,000) except where otherwise provided for in the Purchasing Policies and Procedures.
