SubscriptionBridge + Authorize.Net's Automated Recurring Billing (ARB)
Why do I need both?
Authorize.Net provides recurring payments through its Automated Recurring Billing service, which can be added to your Authorize.Net account (currently $10/month - see complete Authorize.Net pricing).
SubscriptionBridge adds a number of subscription management and customer service features. In a nutshell, here is how the two systems work together:
Recurring payments are processed through Authorize.Net's ARB service (no credit card numbers are ever stored by SubscriptionBridge). But Authorize.Net has very limited "customer service" features built-in. And that's where SubscriptionBridge comes to the rescue.
