Add a payment method to a monthly membership for your customer
How do I change the payment method for my customers' membership?
If a customer has a monthly membership that doesn't have payment information saved, or they would like you to change how they are billed on their behalf, you can add a new payment method to their membership.
To do this go to their membership detail page (Customers >> Customer List >> Choose the desired customer >> Membership tab >> Choose active membership), click Payment method and you will see an option to add or change Payment Method.

You will then be taken to a page where you will be able to add new payment information and choose from the available payment methods.
