Hello @ShopAdmin,
Since you've tried the browser troubleshooting steps, I recommend contacting our QuickBooks Customer Care Support. Here's how to reach out:
- Go to (?) Help, then Contact Us.
- Enter a brief description of your concern, then Let's talk.
- Select Start a chat.
With the above steps, we will be able to create a case for you and investigate further. I've added this awesome article about applying credit notes for more information.
We also have a guide on managing customers and income that you might find helpful.
Please let me know if you have other questions or concerns. I'd be around to assist you further. Thanks for posting, take care.
