Q: Why is my invoice not syncing?
A: There may be some discrepancies between the line items in the invoice and how they are represented in your accounting software. Consider renaming some of the line items (don't use spaces) and trying to re-sync.
Q: I'm getting an error: The transaction could not be locked. It is in use by another user
Sometimes this can happen if:
Another user recently had it open and didn't fully close it
QuickBooks didn't properly release the lock due to a crash or network hiccup
A background process like a sync or backup is briefly accessing the invoice.
To make sure QuickBooks fully releases its hold on the invoice, try the following steps:
Ask all users to log out of QuickBooks Desktop completely — even if they don’t think they were working on the invoice.
Close and reopen QuickBooks, just to refresh the session.
Then try syncing again. If you're absolutely certain you're the only one logged in, restarting QuickBooks and your computer may also help clear any lingering locks.
