The University of Wisconsin is not one buyer. It is a system of 13 universities, from UW-Madison down to the regional campuses, and since the move to ShopUW+ they share one procurement spine. That is good news if you are trying to sell in. Register once in the right system and you are visible to the whole system, not just the campus you happened to email.
This guide covers the two registrations that actually matter, where the supplier diversity goals sit, and how to read a contract before you spend a week on a bid.
Who buys, and through what systemThe UW System runs procurement across its 13 universities through ShopUW+, its procurement platform. Supplier registration, sourcing events, bid submission, and contracts all flow through it. The supplier side of ShopUW+ is a Jaggaer Supplier Portal, which the UW System describes as its secured single point of entry for suppliers to update information and receive invitations to sourcing events.
Practically, that means if your firm is normally paid through a non-PO invoice, the UW System requires you to register and keep your data current. Registration is not just a marketing list. It is where you provide banking information for ACH payments, satisfy the IRS requirement to collect a W-9 (or W-8BEN for foreign individuals), and get classified correctly as a vendor. No registration, no payment.
What does the university buy? The honest answer is almost everything an institution running research labs, dormitories, hospitals, athletics, dining, and a dozen campuses needs. Lab supplies and scientific equipment, IT and software, construction and facilities trades, professional and consulting services, food service, furniture, printing, transportation. If you sell a legitimate commercial product or service, there is a commodity category for it.
Step one: register in ShopUW+ (Jaggaer)This is the registration that gets you into the system and gets you paid. The supplier invitation in the Jaggaer portal collects your tax ID, supplier type, contacts, addresses, tax documents, and diversity information. The portal also lets you securely upload banking details for ACH, certificates of insurance, and your diversity certifications.
A few things worth knowing before you start:
- Have your documents ready. W-9, certificate of insurance, and any diversity certification PDFs. Uploading them during registration is faster than coming back later.
- Your diversity certification lives in your supplier profile. If you are a certified MBE, WBE, or veteran-owned firm, attach the certificate so it travels with your record. That is what makes you findable when a buyer filters for diverse suppliers.
- Support exists. For questions about the ShopUW+ Jaggaer Supplier Portal, the UW System Shared Supplier File Administration Team is reachable at SupplierFile@bussvc.wisc.edu or (608) 262-5748. For technical portal issues, Jaggaer Supplier Network Support is (800) 233-1121.
ShopUW+ gets you paid. VendorNet, the State of Wisconsin's bidder-list system, is how you find out a bid exists in the first place. The UW System uses VendorNet to post official sealed bids and requests for proposals, and vendors who register there receive notification of State of Wisconsin and UW System solicitations.
When you register on VendorNet you select NIGP commodity codes for what your company sells. Get these right. They are the filter that decides whether a UW solicitation in your category lands in your inbox or never reaches you. Pick too few and you miss work; pick everything and you drown in irrelevant notices. Be honest and specific.
The combination is the point. Jaggaer/ShopUW+ for the relationship and the money, VendorNet for the deal flow.
The supplier diversity angleWisconsin has a real, named program behind its diversity spending. The Wisconsin Supplier Diversity Program (SDP) certifies three categories: Minority Business Enterprise (MBE), Woman-Owned Business Enterprise (WBE), and Disabled Veteran-Owned Business (DVB). The SDP verifies that a business is at least 51% owned, managed, and controlled by members of the relevant group.
Two levers matter here:
- The MBE goal. UW-Madison states a commitment to direct 5% of state purchasing and contracting to certified MBEs. A spending target is not a quota you win automatically, but it means buyers across the system are measured on it, which creates genuine pull toward certified MBE suppliers.
- The DVB bid preference. Certified DVB firms may receive a permissive 5% bid preference on state contracts. On a competitive bid, a 5% scoring advantage is often the difference between winning and placing second.
So which certification should you carry? For state-and-university work in Wisconsin, the state SDP certification is what plugs directly into these goals and preferences. National certifications also matter. NMSDC certification is the credential most corporate and many institutional buyers recognize for minority-owned firms, and it is worth holding if you sell beyond Wisconsin too. If you are weighing which to pursue first, our guide to NMSDC certification walks through what it covers and how it differs from government programs.
Make your registration earn its keepRegistering is the floor, not the finish. A few habits that separate suppliers who win UW work from suppliers who just sit in the database:
- Keep your ShopUW+ profile current. An expired insurance certificate or a stale diversity certification can quietly disqualify you. Set a reminder for renewal dates.
- Tune your VendorNet commodity codes after your first few months. If the notices you get are mostly noise, narrow them. If you are seeing nothing, you may have missed a category.
- Lead with your certification where it counts. When a solicitation references diversity goals, your attached SDP or NMSDC certificate is the evidence that lets a buyer count your spend toward their target.
If you are not certified yet, that is usually the highest-leverage thing to fix before chasing UW bids. The certification is what activates the 5% goal and the DVB preference, and it is the same credential that opens doors at other public buyers. You can see how the University of Wisconsin sits among other institutional and corporate buyers in our supplier diversity program directory, and you can list your own firm in our supplier directory so buyers searching for diverse vendors can find you.
Next stepIf your business is not yet certified, that is the bottleneck worth clearing before you spend weeks on UW bids. CertifyAll handles the certification paperwork for you, so the credential that unlocks Wisconsin's MBE goal and DVB preference is in your ShopUW+ profile before the next solicitation drops. Start there, then register, then watch your commodity codes.
