QuickBooks online by default will have Visa, MasterCard, Discover and American Express turned on in the Payment Method List. If a credit card is missing or the Process Credit Card Payment is grayed out on the Sales Receipt or the Receive Payment screen, the credit card types will need to be edited or added to the Payment Method List.
If the credit card type is missing from the list, follow these steps to add it:
- Choose Gear Icon > All Lists.
- Click on the Payment Method List.
- Click New.
- Enter the credit card name and click on the Credit Card box to select it.
- Click on Save.
