I appreciate you sharing your experience and observations with the Account Summary section, cbr20.

I understand how important it is for customers to see their full outstanding balance, as it's a critical feature for preventing underpayments.

In this case, I'd suggest reaching out to our live support teams. One of our support agents will take a closer look at this to determine why the Account summary section is not appearing on some invoices.

Here's how to reach out to them:

1. Click the Help menu in the upper-right-hand corner of QBO.
2. Proceed to the Assistant tab.
3. Type in "contact support" in the chat box and press Enter.
4. Select Contact a human, then click Live Chat or Call me back.
5. Type in a short description of your concern and click Continue.
6. Choose between Callback or Chat.

Please know that you can always reach out to us anytime you need help.
