Chargify's billing portal provides a convenient interface for your customers to update their credit card and billing details, change plans and number of addons, as well as cancel their subscription. Best of all, modifying what actions are available for your customers can be done through the Chargify UI, all without having to write any code. 

To further enable your customers ability to manage their own accounts, we are excited to announce new Service Credit and Prepayment balances to the billing portal view. Your customers will know exactly what balance already exists before an invoice is issued.
