Hi PBrown22,
Thank you for the additional details. I understand how challenging this is, especially if you have tons of invoices. I'm here to help you.
Yes, QuickBooks will assign transaction numbers in sequential order, but that's only if there isn't an assigned number on the next invoice. In this case, both users are entering specific numbers already (123 and 456). Therefore, the program should not change the number on the other invoice.
Let's do some steps to resolve the issue.
First, you'll want to update QuickBooks in both locations to fix any damaged program files that may have caused this behavior.
- Go to the Help menu and select Update QuickBooks Desktop.
- Go to the Update Now tab. Tip: You can select the Reset Update checkbox to clear all previous update downloads.
- Select Get Updates to start the download.
- When the download finishes, restart QuickBooks.
- When prompted, accept the option to install the new release.
Second, back up the company file and run the Verify and Rebuild data utilities on the host computer where the company file is saved. The other user shouldn't be accessing the file at that point.
If you'll still encounter the same issue after doing the above steps, please contact our QuickBooks Desktop Support. That way, they can use more tools to check this further.
The Community team is always available should you have other concerns. Take care and have a good one!
