You can use any payment method activated in your WooCommerce to pay for a subscription, however, if it isn’t one of the supported payment methods, the customer will have to pay the renewal order manually.
To find out which payment gateways support automatic charges, please refer to this page.
How can I pay for a renewal order if a non-supported gateway has been selected?
One day before the renewal date, a new order will be generated automatically. This order will be visible for the users in ‘My account > My Subscriptions’.
Customers can just click on the ‘Pay’ button that will redirect them to checkout page and complete the payment with any gateway.
