Frequently asked questions for suppliers

All onsite visits from suppliers have been suspended. Suppliers are encouraged to use Zoom for conference calls with UD employees. For delivering to campus or performing services on campus, please confirm building access with your UD point of contact. Call the Office of Procurement and Payable Services if you cannot reach your on-campus contact.


Central Receiving is open 8 a.m. to 4 p.m. weekdays. Packages are being delivered to offices not working remotely, but there may be delays because of limited staffing.


Request a contract or purchase order for all goods and services sold to the University to facilitate the invoice payment process. Click here for info on how to submit a purchase order.

Please check with the purchase order owner to verify if goods and services are still needed. If a purchase order needs to be closed in Runway, please reach out to purchase@udayton.edu to request this change.
