Hello there, kong-meiwai-tita.

Thank you for posting here in the Community. I can share information about the error messages when you try to create sales receipts in QuickBooks Online.

I have also replicated the issue on my end, but I did not receive any error messages. To resolve the error message you encountered when creating a sales receipt in QuickBooks Online and selecting "Undeposited Funds" in the "Deposit to" field. You need to perform a basic browser troubleshooting.

Here's how:
