Hi 👋 it won't be. The system will try to charge for it but will fail to do so when it doesn't find a payment method to charge.

Ah, even if the customer has valid payment methods attached, and we have the Smart billing enabled?

Yes, we will not attempt to charge a Payment Method that we have not been told to charge.

If the Customer has a default payment method defined in invoice_settings.default_payment_method then that will be used. If one is not present there then we will look to the default_source field. (There are a couple other fields we check first on Subscription objects if the Invoice is associated with a Subscription)

If we are unable to find a payment method specified in those fields, and one was not provided on the Invoice directly, then automatic payment attempts will be triggered but will immediately fail.

Understood, thank you Toby!

Any time!
