Make a rate default so you can access it directly from the Dashboard. When you click Rate management from the Occupancy section of the Dashboard, you'll be taken to the Pricing tab of your default rate.
Go to Main menu > Settings > Services.
Select your bookable service, then click Rates.
Click on the name of the rate you want to make default.
Switch the Default toggle.
Note: You can only have one default rate—if you want to delete it, you'll have to make a different rate default first.
