All clients must have a verified billing method on file at all times. It is possible to add multiple credit cards or PayPal accounts, but you can only set one as your primary billing method for billing purposes.
If you need to change primary credit cards:
- Add the new credit card or PayPal first. You must verify and set your new credit card as the primary.
- Remove the old credit card.
If you have multiple credit cards on file, you can remove all but your primary credit card.
