Duplicate Bills

I recently upgraded to QB 2019 Desktop from QB 2016 Desktop.  Although my preferences are set to warn me about duplicate bill #'s for the same vendor, this feature is not working.  We import our payables from another system by .iif files.  This feature worked fine with our 2016 version.

Re: Duplicate Bills

I'm here to help, @lreizer.


Let's try some troubleshooting steps by toggling the Warn about duplicate bill numbers from same vendor feature to warn you on the duplicated bill numbers.


To toggle, you'll just have to uncheck Warn about duplicate bill numbers from same vendor. Then, click save and mark it again. Once done, let's import your payables from another system by .iif files in QuickBooks Desktop.


If it still doesn't work, let's run the Verify Rebuild Utility Tool. You may refer to this article for the detailed steps: Resolve Data Damage on Your Company File.


If the error persists, I suggest contacting our support team. They have the right tool to help you with your duplicated bill number.


Here's how to get in contact with them:

  1. Open QuickBooks.
  2. Go to Help and select Support.
  3. Under Additional resources, click on the Contact us link.
  4. Select a topic.
  5. Choose either Get Phone Number or Start a message.

Please don't hesitate to leave a comment below if you still have other concerns. I'm always here to help. Have a good day!
