Good day to you, kkhenryocenn,
I'm here to help add another payment method in QuickBooks Online (QBO).
QBO International only accepts credit card payments for your expenses and daily sales. Other methods are writing a cheque and creating a bank transfer.
You can look for a third-party app that accepts customer payments. Then, record your sales in QuickBooks.
Check out the Record your payments to credit cards page to help manage your credit card transaction. It includes alternative methods, use banking download, and match transactions.
Stay in touch if you have follow-up questions. I'm always right here to help.
Thank you and stay safe!
