Thank you for this suggestion Freddy. As I understand it, what you want is the ability to invite the customer to a server in your account and then enable them to add their own payment method, essentially?

This can already be done by turning this around a bit. Simply, ask the client to create a Webdock Account. Write support and ask them to move the server to the client account, finally ask the client to invite you to the account so you have access.

Granted, this does not give you a "birds eye" overview and easy access to all client servers simultaneously but required you to log in to any given account to do management.

Your idea does have some merit and I think it is doable without too much engineering on our part so we will take this under review and see what we can do here.
