I appreciate you following the solution provided by my colleague in this thread, Divnick.

Let's try one more troubleshooting step so that QuickBooks will show the correct balance when printing an invoice. There are possible data issues on your company file.

Make sure to update your QuickBooks to its latest release. It helps you give a better experience and fix issues. Check out this link for instructions: Update QuickBooks Desktop.

After updating your QuickBooks, back up your company file so you can go back whenever you run into some issues. Then, do the clean install to fix the damage on your company file.

After performing the clean install, restore the company file and print again the paid invoice. The partial invoice should look like this. Please see the attached screenshot below for your visual guide.

If it still shows the full amount, I recommend contacting our QuickBooks Desktop Live Team. They can pull up your account and check your company file.

Stay in touch with me if there's anything else you need about printing an invoice. I'm always right here to help ensure you're able to see the correct balance when you print it.
