I can't save an invoice to quickbooks online

Good day, @123446.

Did you get any specific error messages when closing your invoice? 

If you're getting this prompt "You and <User> were working on this at the same time.<User> finished before you did, so your work was not saved.", this means that your account is also affected by the ongoing investigation (INV-56437).

If this is the case, I'd recommend contacting our customer support. This way, they can add your details to the list of affected users. Then, send you an email update once our engineers fixed the issue.

If you haven't received the exact error message, then let's perform some basic troubleshooting steps. This way, we can trace why you're unable to save the invoice. 

To start, open your account in a private window. This will help us check if the concern is browser-related. Sometimes too much cache build can cause unexpected behavior with the product. Just press the following shortcut keys to access this mode:

• Press Ctrl + Shift + N (Google Chrome).
• Ctrl + Shift + P (Firefox).
• Control + Option + P (Safari).

Once done, try saving the invoice. If you're able to do it, go back to your regular browser and clear its cache. You can also use another supported browser to open your account and save your transaction. This might be a temporary issue with QuickBooks and the current browser you're using.

Additionally, there are several financial reports you can run to track your sales income in QuickBooks. They will show you helpful insights on the things you buy and sell, and the status of your inventory.
