The same way as for booking portals in Channel Manager, you can set different prices for Booking Engine only. See the step by step instruction below.
STEP 1 - Create a new rate
In Rate Manager, click on Add Rate button, next add a name for the new rate, for example, Booking Engine or Website, and save it.
STEP 2 - Set up prices
When the new rate is created, set up prices that you want to show on the booking engine. Go to Prices and insert the prices for the new rate.
STEP 3 - select the rate for Booking Engine
Now, change the default Standard Rate for Booking Engine. Go to the Property Settings / Booking Engine / Payment & Rates and select the rate you want to use on your website.
Remember to save the changes!
You can use multiple rates on your booking engine.
