Log in or register as a user to begin using Vendor Self Service
Vendor Self Service gives existing and potential vendors access to their business information and records online. To begin registration, select Vendor Registration on your left. Note: A W9 must be attached before access will be granted. Existing vendors will need their vendor number (located on the last received check stub, PO, or EFT voucher) and Federal ID #. If you have not received a check recently or ID # does not match when entered, please send email to accountspayable@dover.de.us. The Resources Menu is in the upper right corner, to the left of the question mark.
