Procurement Services


Vendor Setup

Any person or entity that is paid by Winthrop is considered a vendor and must complete the required form(s) below in order to do business with Winthrop. 

The vendor must email form(s) to purchasing@winthrop.edu before any purchase of goods or services has been agreed to. 

Banner will not let a requisition be entered until Procurement Services has added the vendor's profile to Banner.

Required Vendor Forms:

    • W-9
    • W-8BEN for grants, scholarships, or fellowship payments
    • Form 8233 for services
    • Note: If the vendor's country is listed here then they may qualify for a reduced withholding rate. International tax is complex and it is up to the vendor to complete the form completely & accurately. We may recommend that they engage a tax professional from their country to support the completion of this form if they lack sufficient expertise.
    • Previous "Foreign Vendor Request Forms" are no longer accepted in lieu of the requirement above. This is an updated practice as of 2025 and will be gradually actualized throughout 2025-2026.
    • W-8BEN-E
    • Note: If the vendor's country is listed here then they may qualify for a reduced withholding rate. 
    • Previous "Foreign Vendor Request Forms" are no longer accepted in lieu of the requirement above. This is an updated practice as of 2025 and will be gradually actualized throughout 2025-2026.

Vendor FAQ:

    No. Vendors should include a flat fee in their quote for travel expenses and manage their own travel arrangements.  Booking travel for vendors or agreeing to pay for actual travel expenses is highly discouraged. 

    It depends. If the vendor was required to complete a CPS form and is performing services that are neither speaking nor administrative, then proof of insurance is required. Also, the vendor should have Winthrop University listed on their insurance as "additionally insured."

    It depends. Individuals (i.e. vendors that are not a C-Corp) cannot be paid using a P-Card. Payments for services related to a Winthrop contract cannot be paid using a P-Card. Click here for more P-Card information.

    No. When the vendor accepts our purchase order, they are agreeing to "net 30" pay terms, which means they will be paid within 30 days of Winthrop receiving an invoice after the goods have been delivered or the service has been performed.
