Hi, Lacey4a. You can navigate to the Sales transactions page and check the Sales widget right on top to quickly determine the total outstanding and paid invoices for September.
You can follow these steps:
- In your QBO account, click on My apps.
- Select Sales & Get Paid, and then Sales transactions.
- From the Date filter option, choose This month, Last 30 days, or Last month.
- From the Type dropdown, select Invoices.
- Check the widget at the top of the page for open, overdue, and paid invoices. See attached screenshot below.

Moreover, you can learn more about the recent change of QBO's overall design. Feel free to check out this article: Explore QuickBooks on the Intuit Platform.
Aside from the widget on top of the Sales transactions page, you can alternatively generate a report that shows overdue, paid, and unpaid invoices for the month of September. To help generate a report and customize it, refer to this guide: Create an invoices due on a specific day report.
On the other hand, if you're referring to how to individually check the outstanding balance of a single invoice using the Modern layout and its paid amount, here are the steps to follow:
- Open an existing invoice.
- View the Balance due and the Amount paid at the top right portion of the screen.

- This information can also be found at the bottom part of the invoice screen.

I understand navigating these recent changes can be quite a task. If you have further queries, feel free to give us a reply. Take care!
