Re: Customer refunds
Thank you for sharing detailed information about the items still coming up on your Unbilled Expenses by Project. Allow me to step in and help provide other troubleshooting steps to resolve this issue.
If this is caused by internal error, rebuilding your data should fix the issue. Since you're still having this problem, let me refer you to this article for other solutions: Top data damage errors in QuickBooks Desktop.
I'd also suggest reaching out to our Tech support again and provide your case number since this issue hasn't been resolved yet. I'm sure they are investigating this unusual behavior to get this resolved.
Should you need anything else or have other questions about the error codes, please let me know. I'm here to help.
