What is VendorNet?

VendorNet provides easy access to a wide variety of information of interest to vendors who wish to provide goods and services to the state as well as state agencies and municipalities. Bidding and the time required to identify new vendors is minimized while vendors are automatically notified of opportunities in their area of interest.

General information on how to do business with the state, names, addresses and telephone numbers of state agency procurement staff, and a summary of what the state buys and how much it spends is included. In addition, information on certified work centers, minority business enterprises, recycling and affirmative action programs is available.

Please note, VendorNet does not provide information on highway or construction projects; VendorNet is related to purchases of goods and services only. Please see the Department of Administration, Division of Facilities Development Web site for information on construction projects and the Department of Transportation for road and airport construction projects.

Registration  Vendor

As a registered vendor, information you provide on your company and its goods/services is stored in the central statewide vendor database for inclusion in bidder list as they arise. The annual registration gives you automatic notification of all state agency procurements* over $50,000 in your areas of interest. You may elect to be notified of opportunities electronically or by first-class mail while also having the ability to search for and download current bids and state agency contracts at your convenience.

Simply complete the on-line registration process. 

Municipality  Municipality

S. 345.05(1)(c), Wis. Stats., defines Wisconsin municipalities as any county, city ,village, town, enumerated school district or any other political subdivision of the state. In Wisconsin, the technical college campuses are considered municipalities, not state agencies. Municipalities are able to acquire many products and services through contracts listed on the VendorNet System. Savings ranging between 20% and 60% off retail prices can be realized through the use of these statewide contracts. VendorNet maximizes the subscriber's time and money by getting the highest value for the taxpayer's dollars.

VendorNet can also reduce staff time required to research specifications, minimize bidding, and reduce the time required to identify new vendors. A registered municipality can search for current contracts available for cooperative purchasing and download contracts that they may want to use. In addition, municipalities will be able to post their own municipal bids and proposals on VendorNet, expanding the distribution of these documents to a broader vendor base and maximizing competition on their procurements.
