Hello there, 303User.
I can see how adding a flat percentage when paying with a card is a great feature. With that, I'd suggest sharing this great idea with our developers.
Here's how:
- Select the Gear icon at the top, then Feedback.
- Enter your comments or product suggestions. Then select Next to submit feedback.
You can track feature requests through the QuickBooks Online Feature Requests website.
Feel free to check this article as your guide in recording invoice payments: Record invoice payments in QuickBooks Online.
I'll be around whenver help is needed.
