Billing Status
        If you are using Time Slips 
 you can select the billing status for service activities in the service 
 record, in the time slip, and when entering the sales invoice. You can 
 select from one of three billing options:
        
            - Billable. 
 An activity which you charge a customer. For example, a billable item 
 may be the repair of a car.
 
            - Non-billable. 
 An activity that is free for the customer, but does not appear on an invoice. 
 For example, if an employee makes a mistake on a repair, and it must be 
 completed a second time, the second repair would be non-billable.
 
            - No 
 charge. An activity for a customer that you offer for free, such 
 as a warranty repair.
