Generally, you are required to provide platform-specific markup rates in order for us to push pricing to your listings.
For a more granular pricing control, you also have the option to set a markup rate applicable only to a specific listing within a property group.
To do this:
Go to Properties
Click on the property name
Click on Markups under Pricing & Availability section in the submenu
You may enter a negative, zero or positive value in the field for the markup rate
