I entered my invoice number in the Invoice number field and no results came up.

I entered my UserID and password correctly and I still get the error message "Your User ID and/or Password are invalid."

In Vendor Self-Serve, both the UserID and Password are case sensitive. Ensure that you entered both using the proper case. If you use the number pad on your keyboard, ensure that "Num Locks" are on for any numeric values in your User ID and / or Password.

When I log in to VSS I used the search bar to look for an invoice but nothing came up. How do I search for invoices?

The search field at the top of the navigation bar is used to search for Core-CT modules. Since VSS only has three you will not need to use this search bar. Use the following steps to search for invoices. From the blue navigation bar select Review Payment Information, then Invoices. The default settings search for invoices in the last month. Modify the time frame for the search criteria if necessary and click Search.

On the Invoice screen the Scheduled Pay Date field Says last week and I still haven't received my payment. What happened to my payment?

The invoice screen allows you to see items that the agency has entered but may still be in the process of approving. The Scheduled Pay Date you see in the system is an estimate of when the payment might be made. Holidays, invoicing or purchase order problems, vacations, or other scenarios may arise which push a payment past its scheduled date. Only use the Payment Date from the Payments inquiry in VSS to tell when funds are actually paid. If you have questions about a delayed payment you can contact the agency directly by going to the Accounts Payable link on the VSS homepage and scrolling down to find the agency contact name, phone number, and email address.
