Hello There
It is possible to manage the billing information using the Checkout existing subscription API. This returns a checkout page for existing users without card details(usually on a trial/free subscription) using which your customers can enter both their payment and billing details.
Your customers can also manage the billing information using the Self-Serve Portal. Here the customer can edit their personal information, billing and shipping addresses as well.

I would like to have a hosted page for managing billing informations for existing customers.
I really like the option to have a manage payment sources hosted page, but it would be great to allow users to manage their billing information (address, name, ... - same as during checkout) through a hosted page.
