Opt-in Billing | Disable Billing Address for Subscriptions - This plugin will prevent Commerce from asking customers for their real name and address when purchasing a subscription.
Disable billing addresses completely, or allow the customer to choose whether to enter a billing address by enabling the billing feature. The billing option will work for all purchases that don't require billing information, not just subscriptions.
If desired, disable billing addresses for all physical products. Useful, for example, if you want to use Commerce's shipping feature to track non-physical items.
Please note that if you are using PayPal as your payment gateway with Billing Agreements set to Required, this plugin will not be able to help you because PayPal requires address information for Billing Agreements. If billing agreements are optional or disabled, this plugin will work well with PayPal.
