How can i fix an application error

Let me help you fix this error, Jrsound.

Sometimes, this is caused by browser-related issues. May I know what specific application error code are you getting? In the meantime, we can perform some troubleshooting steps to fix the problem. You can use the shortcut keys below to access the private window.

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

This mode deletes cookies and browser history leaving them clean and easy to access any websites and error-free. Once done, double-check if you can already add a supplier without getting the error. If so, go back to the main browser to clear its cache and delete some outdated files that might be the cause of the error. Otherwise, use a supported, up-to-date browser.

Furthermore, learn how you can view all suppliers that you've added by running a report. You'll only have to customise them to ensure you're getting the right data. I've added this article for more details: Customise Reports in QuickBooks Online.
