I appreciate you joining this thread, @vitanovabookkeeping.
You cover almost every troubleshooting step in trying to issue a partial refund.
As far as I want to look into this further, QuickBooks Community has limited tools. That being said, I recommend contacting our Customer Support Team. They can further investigate the root cause of your issue and help you change the amount for the partial refund.
To reach them, please follow the steps below:
- Log in to your QuickBooks Online company.
- Go to the Help (?) menu.
- Click Contact Us.
- Enter your concern, then choose Continue.
- Select Chat with us or Have us call you from the next available expert.
Moreover, let me share this resource on how to void or refund customer payments you process in QuickBooks Online. It also includes some ways how to give partial refunds.
Let me know how it goes with our support team. I want to make sure everything is taken care of. Keep safe and healthy always.
