You askedWhen I write a invoice and send to the person paying me it keeps coming up with the amount due as $0 or I have been paid.

Hello there, @howiesgardencare.

Let's turn off Automatically apply for credits from the account and settings.

Here's how:

1. Go to the Gear icon.
2. Click Account and Settings.
3. Select Advanced.
4. In the Automation section, uncheck the Automatically apply credits.
5. Click Save.
6. Hit Done.

Please let me know how it works. I'm always here to help. Have a great day!
