Let’s work together to troubleshoot this issue, Alan.

To get started, could you let us know the exact error message you’re seeing when trying to save the item while creating an invoice? Any details you can share will help us figure out what’s going on and find the best solution for you.

In the meantime, try logging out of your QuickBooks Online account and then logging back in. Sometimes, a simple refresh like this can clear up temporary glitches.

If you have any other QuickBooks questions or concerns, don’t hesitate to reach out. We’re always here to help.
