How to Make a Purchase

This guide will help determine when a department can engage with suppliers directly or if the help of Purchasing Services is required.

The University of Wisconsin–Madison is subject to State of Wisconsin purchasing statutes and rules. Information on this page explains the rules for purchasing goods and services at UW–Madison.

Buying products

Many items can be found at ShopUW+ or through contracted vendors. ShopUW+ is an efficient way to make business purchases and carries commonly used items such as lab supplies, office supplies, computer hardware, and maintenance, repair, and operational supplies (MRO). ShopUW+ is a university resource that saves time and money.

Purchasing Services also manages contracts for many other items and services. The contracts have been negotiated to include favorable pricing and protective terms in case issues arise.

If the product or good can’t be purchased through those methods, a more structured buying process is required.

There are three ways to buy products and goods:

    • Through a contracted vendor at ShopUW+
    • From a contracted vendor not at ShopUW+
    • From a vendor not on contact

Buying services

The purchase of services such as maintenance, instructional, research and consulting require additional considerations and require the involvement of a procurement specialist.

Items requiring special approval
