Create add-ons and assign them to your bookings.
Set a price for each add-on and choose whether to charge this per hour or per booking. This will be an extra charge added to the original booking price.
Add-ons can be made public or private so that only you can assign certain add-ons to a booking.
Add-ons are great for things like instrument hire, books or any other extras you want to offer as part of your bookings.
