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.
Adding a markup rate will not automatically update prices on your booking platforms unless you have Pricing Sync enabled. If it is, it will update immediately. If not, once a markup rate is in place, that markup will be added to any future price updates.
How To Add A Listing Level Markup
Go to Properties
