Hello accounting618,
Welcome to Community! I can understand the benefit of offering your customers the option to pay their account directly from the invoice they receive. However, QuickBooks Online Payments, is currently available with Canadian currencies only. To learn more about the acceptable payment methods, click here. If you would like to see the payment option extended to other currencies, please don't hesitate to submit a suggestion to our Development Team by going to your Settings ⚙, then select Feedback. Customer recommendations are greatly appreciated in assisting us with improving your overall customer experience in QuickBooks Online.
If you have any other questions, feel free to reach out. We would be glad to help!
