[Feature Request] Whmcs Handle Pro Sites Billing and Invoicing

Hi,

Not sure if you guys have this planed however it would be great if we could get Whmcs to Handle all Pro Sites Billing and Invoicing. (This feature should be optional)

Based on my location I can only use the PayPal Express which doesn't allow us to accept credit cards. So we are limited to only payment via PayPal

However with Whmcs we would be able to use alternative payment gateways which support subscription billing (2 checkout etc.)
