Hi there, @PebbleCreek1,
To be able to add the past due amount to your current invoices, you can simply follow these steps:
- Open your QBDT.
- Click on Customers at the top menu bar.
- Select Create invoices.
- On the Invoice page, click on Formatting.
- Select Customize Data Layout.
- Go to the Footer column then check on the box under Print for Customer Total Balance or Job Total Balance.
- Click on OK to save the changes.
To learn more about using and customizing form templates, you can read this article: Use and customize form templates.
I'm also adding this article as a future reference in case you'll encounter issues when using and customizing templates: Troubleshoot common issues when using and customizing templates.
Keep posted if you have any other questions. I'll always be here to help!
