Hi,

I can't seem to find any examples or reference as to how I can do the following:

1. Subscribe a customer to a pricing plan
2. Add a custom charge to that charge process

Example: Customer chooses Plan A for $15 and adds some additional products/services for an extra charge of $5

From that I have the following questions:

1. Is the custom charges only charged once or are they subsequently billed again during the subscription?
2. Can I alter the custom charge once setup?

Thanks for the help in advance,

Bill
