There are two options you can pick from to determine how your rates are calculated at your campground: Prorate mode and Waterfall mode.
Prorate mode
In Prorate mode, partial remaining periods will be prorated. For example, for a 10 day stay where the weekly rate is $140, the total will be 140 + 3/7 of another week for the additional 3 days for a total of $200 (140 + ((140/7)*3 = 200)
Waterfall Mode
In Waterfall mode, partial remaining periods will waterfall down from monthly/weekly/daily. For example, for a 10 day stay where the weekly rate is $140 and the daily rate is $30, the total will calculated using 1 weekly rate and 3 daily rates for a total of $230 (140 + (30*3) = 230)
Once you have decided which calculation mode fits your business model, navigate to Settings > Property and on the Reservations tab, you can select the mode of your choice. The default mode is Prorate.
Select the rate calculation mode in your property settingsIf you change your rate calculation mode, the new mode will only be used for future reservations and any unit you add to existing reservations. Any existing reservations will not be effected.
If you make a change to a reservation and you elect to recalculate rates, the rate calculation mode that was active at the time the unit was added to the reservation will be used to recalculate the rate.
For example, let's say your rate calculation mode is set to Prorate, and you make a new reservation. You then update the rate calculation mode to Waterfall. You then add another unit to the existing reservation. The rate for the first unit was calculated using the Prorate method and any changes made to that unit where you elect to recalculate the charge will be made using the Prorate method. The rate for the 2nd unit was made using the Waterfall method and any changes that are made to that unit where you elect to recalculate the charge will use the Waterfall method.
