Step-by-Step Guide
Create the extra as a service
Add a service for the extra with its price.
Mark it as an add-on
Under Orders of this service, tick This is an add-on — don’t create a new order and choose its Parent services. Assigning and deadlines aren’t available for add-ons.

Clients buy it with the parent
On an order form, the add-on is offered with its parent service and its price is added to that order instead of making a new one. The order shows it under its Add-ons tab.
Good to Know
