My suppliers list is no longer accessible when I try to add an expense although I can see it in settings. If I click into a supplier there it says something went wrong?

Hi there, @Loubielu.

Let's perform some basic troubleshooting steps to access your supplier lists.

To start, log in to your QuickBooks Online (QBO) account utilizing a private browser or incognito mode to verify if this is a browser-related issue. Since this doesn't store cache files, that causes odd behavior in a web-based program. Feel free to use these shortcut keys:

• Google Chrome: press Ctrl + Shift + N
• Mozilla Firefox: press Ctrl + Shift + P
• Microsoft Edge: press Ctrl + Shift + N
• Safari: press Command + Shift + N

Then, access the supplier list. If this works, clear the cache of your regular browser to remove accumulated data. If the issue persists, use another supported browser or device. It might be that the current one you're using has a temporary issue with the program.

You might want to perform a refund credit to your supplier. Feel free to read this article: Enter supplier credits and refunds in QuickBooks Online.
