If the Automatically apply credits feature is enabled, your customer's newly-created invoice will be marked as paid as soon as you save it, Balivinder.
This feature will automatically apply payments to the new invoice and mark it as paid if your customer has a credit balance. We can turn off the feature to avoid this from happening in the future.
Here's how:
- Go to the Gear icon on the top menu and select Account and Settings.
- Click Advanced from the left menu and hit the Automation section.
- Toggle off the Automatically apply credits option.
- Hit Save, then Done.

Feel free to message us if you have further questions.
