Special Information for Vendors

Responsible purchasing takes into consideration the costs, the environmental, and health effects associated with the full product life cycles. The University is committed to providing a healthy and safe environment for the students and employees in the purchase of products.

The University supports equal opportunities through purchase orders and contracts with the supplier community. We welcome information from suppliers offering high quality and competitive pricing, and we strongly encourage inquiries from small businesses, minority-owned businesses, and women-owned businesses. Suppliers interested in pursuing work with the University should send their information to this address:

Phone: 302-831-2161

Procurement Services is open Monday through Friday from 8:00 a.m. to 4:30 p.m. Visit the Directions page for directions to the office.

The buyers in Procurement are the liaisons between sales representatives and University personnel; therefore, all sales representatives are asked to contact Procurement prior to contacting other University offices on campus. Additionally, the University asks that suppliers not offer gratuities or gifts to University personnel. Buying decisions are based on best value and will not be influenced by other supplier offerings. Please be aware that all businesses providing services on any of the University's campuses will be required to meet the University's insurance requirements prior to any work being performed. Please see the Terms and conditions for University issued purchase orders for additional information.

Small businesses seeking to learn more about the procurement process here at the University, federal agencies, or other corporations are invited to visit the Small Business and Technology Development Center.

Competitive bidding process

The University works to engage a diverse vendor pool with the broadest possible range of participation. All documents remain confidential during the bidding process which is managed to ensure the highest professional and ethical standards.

The Internal Revenue Service (IRS) requires the University to obtain a completed W-9 form from each vendor prior to issuing payments to them through the accounts payable system.

Accounts Payable

Accounts Payable is the division of Procurement Services that is responsible for processing payments rendered on behalf of the University. The standard payment terms are Net 45 days from the date of the invoice. Suppliers may offer discounts for early payment. The University offers the following payment methods:

  • PDH (electronic Payer Direct Hub via UD credit card) — This preferred payment method issues payment "Net" upon receipt and approval of correct invoice. To participate in PDH payments with the University, the vendor must accept credit cards.
  • UD credit card with vendor calling the University for card number when payment is due
  • ACH electronic payment
  • Wire transfer

Invoices for goods and services against a purchase order should be scanned and sent by the vendor to, referencing the appropriate purchase order for timely payment. We review expenses presented on invoices to ensure they comply with University policies and procedures and with local, state, and federal regulations where necessary.
