Hi patrick-el-esca-,
Welcome to the Community. QuickBooks Online is a great program that gives you the ability to easily track your sales and expenses. I'd be glad to help.
At this time. The option for QB Payments for Canadian businesses to allow USD billing to US Customers isn't available. We continuously review product suggestions and requests from our customers that help us to add new features and enhance existing ones, to improve your overall customer experience with QuickBooks Online. I encourage you to submit a suggestion to our Development Team for feature improvements and future updates.
Let me know if you have questions, I'll be happy to help.
