QuickBooks Online offers a hassle-free payment platform that makes it easy to manage your payments. I'll be happy to steer you in the right direction so you can get back to doing what you enjoy.
At this time, QBO Payments only accepts Mastercard, Visa, Apple Pay, and Discover and the transactions have to be processed in Canadian dollars. The payments platform doesn't support USD transactions at this time. I recommend looking at third-party apps such as PayPal which you can ingrate with QBO. To search for the apps which allow you to integrate your USD payment processor with QBO, visit www.apps.com and enter the name of the payment processor you're using in the search field.
Let me know if this info helps. I'll be here in case you have other questions. Otherwise, I wish you a great rest of the week.
