Supplier Registration

A requisition / purchase order cannot be completely processed and the vendor paid unless the selected supplier is currently active in the UW Vendor database. Specific information about each supplier is required for IRS, other tax purposes, various certifications, etc. This information is entered as part of the supplier profile and assures that timely, accurate payments are made and that the University is able to fulfill certain reporting requirements.

The supplier would need to send an email to the Procurement Services Vendor Control team at: and indicate that their address or other company information has changed and provide the updated information in the email. The supplier should include an official company notification or an invoice copy showing the current Tax ID Number (EIN) or new Remit-To information. If changes impact IRS tax reporting, the supplier may be requested to submit a new Supplier Registration form (SRF) for further review.
