Charging the pre-authorized credit card of a client to their first invoice and it's declined multiple times, all info has been double checked. Help? CAD funds.

Hi michaelhiram-icl,

Welcome to the QuickBooks Community. It's a great place to connect with other QuickBooks users and get answers to your questions. Using QuickBooks Payments works with Canadian credit card companies to help you get your funds faster. Approval for a credit card charge is dependent on both parties. I can explain a few reasons the transactions may have been declined.

Keep in mind that QuickBooks Payments works strictly with Canadian cards. Verifying the information is correct and double-checking the card details is a crucial step, which you've done. If you've confirmed the information on your end, there may be an issue with the customer's financial institution. In this case, you should have received a code; here's an article that goes through the different codes and what they mean: Learn about R## codes. This would require reaching out to your customer.
