Rules allow you to enforce policies on new bookings created in the system and can be found through the Inventory > Rules menu in your Checkfront dashboard.
Rules can be opted out of for customers or staff by unchecking the appropriate option in the Apply To field.
By default, your account comes with a global rule set named Default. You can create multiple rule sets and tie them to specific events or discounts in the system. Tying rule sets to events enables you to enforce different booking policies at different times of the year and build more complex pricing layers.
