Why i can't do any bill entry?

Hi there, @actaxguru-gmail-. I'm here to share with you some additional troubleshooting steps so you can track your bill transactions in QuickBooks Online (QBO).

A browser cache may affect the error you're getting. To fix the issue, I recommend opening QuickBooks using a private window. Then, enter a bill from there. It's the best place to check browser-related problems while working with QuickBooks.

To save you time, use either of these keyboard shortcuts:

• Google Chrome: Ctrl + Shift + N
• Safari 11 or newer: ⌘ + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + P

If it works fine, go back to your original browser and clear its cache to start fresh. You can also use another supported and up-to-date browser to narrow down the result.

If you can't select an account from the Category dropdown, our engineers are currently working on this issue to get a resolution as quickly as possible. Thus, I suggest reaching out to our Support Team. Once connected, a live agent can add your name to the list of affected users in this investigation (INV-64933). 

Once your bill transactions are settled and you're ready to track their payments. Check out this link as your reference: Enter bills and record bill payments in QuickBooks Online.

Aside from your bill entries, you can also learn more about handling your vendor transactions from this article: Manage Suppliers and Expenses for QBO International.
