Resource Rate Discounts allow you to apply either a percentage or a flat fee off the price for bookable resources such as meeting rooms, event spaces, etc. This way you can have special booking prices for customers with specific memberships, without modifying the resource rates themselves.
1. Navigate to Billing/Discounts to create your Discount rate.
2. Apply the Discount rate to the Billing plan that should use it.
