Available in Sage 50 Premium Accounting and higher.
If you use the time and billing options in Sage 50 Accounting, you may want to create internal customers and internal service activities to help you to keep track of employee activities that are not directly related to an external customer.
For example, if you want to track an internal activity such as office maintenance, first add a customer with a name representing your internal activities, Human Resources, and then identify the customer record as an internal customer. Then, set up the service activities associated with that customer.
