Hi there, @info1762. I want to ensure you'll be able to process your transactions accordingly while using QuickBooks Online (QBO).
At this time, you may want to check with our Support Team so they can confirm if your Canadian Credit card with postal code is accepted for processing payments manually. To contact support:
Welcome to Community! Having the option to enter credit card payments is a great way to ensure your transactions are complete. QuickBooks Online Payments is an exceptional feature that allows your customers to pay directly from their invoice so you're paid faster. I'll be happy to provide more information so you're on the right path!
Before you can process credit cards you'll need to sign up for QuickBooks Payments. When your customer pays with the 'pay now' option on their invoice you email them, QuickBooks processes the payment for you and applies it to the correct account. Here's how you can get started with QuickBooks Online Payments.
Let us know if you have any other questions. We're glad to help!
I have signed up to process credit cards or I wouldn't have an issue with Canadian cards. QBO doesn't allow you to process Canadian CC manually. This was a non-answer to my question.
