Go to Site Configuration and click Edit Site Profile.
In the General tab, scroll down to the Minimum Room Price field and enter your preferred minimum price.
Click Save Changes.
Once a minimum room price is set, any attempt to save a rate below that amount will trigger an error message—like the one shown below.
⚠️ Important: This setting only applies to standalone IBE managed rates. Prices on Linked Rates and Externally Managed Rates (via PMS or channel manager) will not be checked.
