You will probably spend more time on this tab than any other, as there are a number of settings that are likely to be of interest to you.
The Tariff Configuration mode, and examples of each mode are available on the
Rooms and Tariffs page, so we recommend that you see that page if you want more information on them.
One option of great interest to you will be the Tariffs model. If you charge a flat fee from when a booking is taken to be applied throughout the booking's period, then you'll want to set this to Flat rate. If, however, you want the booking's overall cost to reflect the prices of the bookings which may vary over a period of dates, then you should ensure that this is set to Averages.
You may also want to consider the "Tariffs are gross" option. This tells the system if you've entered gross (tax inclusive) prices for your rooms and optional extras. If you have, then the system will display different information in the booking form. Many countries laws insist that nett and gross information like this be available when online purchases are made.
