If you have a performer that requires different commission amounts for different types of events, you can add commission rates to their contact record through the contact further information page. To begin open the contact, and then click on 'View Further Information' option in the sidebar menu.
On the next page scroll to Commission Rates section then click on the link to show the add rate form. Add a name for the commission and the rate required and then click the 'Add Commission Rate' button.
You can add as many commission rates as required by repeating these steps.
Once your commission rates have been set you will be able to select them when adding services to a booking.
