Vendor Registration

The County of DuPage uses DemandStar by Onvia (DemandStar) to advertise our business opportunities. DemandStar is an e-procurement network of hundreds of agencies. We encourage you to participate with us in this efficient new way of doing business.

This new electronic purchasing service will notify you immediately by e-mail or fax when a government bid or quote opportunity opens in your areas of interest. You can go to our website and download bid documents free of charge or order them directly from DemandStar for a nominal charge. Blueprint/plans can even be viewed online using your Internet browser; there are no additional software requirements!

To find out how you can receive automatic bid notifications, go to www.demandstar.com or call toll-free 1-800-711-1712*.

We reviewed this program carefully before we joined the DemandStar network, and we believe it is an important step toward improving our procurement processes and our services to the community.

Membership in DemandStar by Onvia is not a requirement although, registration is necessary to download the documents. You will still be able to get our bid information through our advertisements in the Daily Herald newspapers. We encourage you to investigate the competitive advantages of automatic notification and electronic quoting by registering with DemandStar.
