The University is committed to paying its suppliers in the fastest and most efficient fashion possible. Below are requirements to ensure compliance with state and federal guidelines:
University of Washington payments terms are Net 30 days from receipt of goods or properly completed invoice, whichever is later. Payment in advance (including deposits) is prohibited excepted in limited situations.
New suppliers must complete the online UW Supplier Registration Form and enroll for electronic payments before an invoice can be paid.
- Suppliers should bill separately for each UW Purchase Order; invoices referencing multiple Purchase Orders are not accepted.
- Suppliers should bill the UW only for items shipped or services already provided.
- Suppliers should submit an invoice to the University of Washington based on the instructions included on the purchase order; suppliers who are part of the Ariba Network must invoice using the Network.
- Suppliers should provide complete and accurate information. Using your company invoice, provide the following information:
- UW-issued Blanket Purchase Order (BPO) or Purchase Order (PO) number
- Shipping address
- Remit-to address
- Invoice number
- Invoice date
- UW customer contact (the person who placed the order)

- Sales tax when applicable
- Clearly marked invoice total
Suppliers are expected to communicate with our central office to keep their company data current. Changes to addresses and some information is easily communicated to VControl@uw.edu. Other company changes, such as business name or Taxpayer ID Number, require a new Supplier Registration Form (online Substitute W-9) to be submitted. See our UW Supplier Registration website for more information.
The UW is not tax exempt, so therefore tax must be included on all invoices unless the items ordered:
- Are indicated as being purchased for resale;
- Are indicated as being purchased for use in doctor prescribed treatment of medical patients;
- Are indicated as being delivered (shipped) directly to an out-of-state address;
- Or, are otherwise specifically exempted from sales tax by the Revised Code of Washington.
