Retrieve future billing estimates

Future billing lets you view potential future charges for an account, without applying them.

When viewing future charges Smile generates a future invoice for a specified rating period, displaying the value of :
  • usage charges in the current rating period
  • recurring charges and deferred charges for future rating periods

A future invoice assumes that all previous future invoice periods have been invoiced. Only the recurring and deferred charges for a specific invoice period are included in the future invoice for that period.

The getFutureBilling() method retrieves a future invoice list for an account, including subscriptions.
