In the event that you wish to update a Clients Billing Information on their Schedule you can do this from the Billing Chart screen. The new Billing information captured will then be applied to all future Tasks or Unconfirmed historical Tasks.
In the event that this Schedule already has Completed and Confirmed Tasks, and you wish to apply this new Billing to these Tasks, you will be required to re-confirm these Completed Tasks on the To Confirm screen to apply this new Billing Information. The alert below will notify you of this.
