Thanks for joining the thread and following the suggestions above, @kep2.

Let me share additional troubleshooting steps to help address the issue and fix the problem. This way, you can apply the vendor credits in the Pay Bills window.

To begin, can you please let us know if you are experiencing the same issue with other vendors in the Pay Bills window? If so, we can run QuickBooks Desktop tools to fix any problems in your company file.

First, download the latest version of QuickBooks Tool Hub and save it in a convenient location. Follow the on-screen instructions to install it and agree to the terms and conditions. Once the installation is complete, double-click the icon on your Windows desktop to open the tool hub.

Next, refer to step two of this article on how to use the tools to address the issue: How to use the tools in the QuickBooks Tool Hub.

If the issue persists, I recommend contacting our phone support. They can review your account in a secure environment and help identify the possible cause of the problem and resolve it.

If you would like to review your financials after resolving the issues, you can refer to this guide to see what reports we can run:  Understand reports. 

Please let me know if you have any other concerns regarding your bills and other entries in QuickBooks Desktop. I am here to assist you.
