Hello, @kcandido.
At this time, we're unable to modify the credit note template in QuickBooks Online (QBO). The form style follows the style used in the standard invoice template. I'll take note of this and share your concern to our management team. This way, our product engineers will know and review this further. That being said, the option to customize the credit note might be added in future updates.
To stay updated with the QuickBooks latest news and updates, you can always visit our blog.
Drop a comment below if you have any other questions. I'm always here to help. Have a good day!
