For example a Contract Name setting '''ABC*1.23''' will multiply all prices by 1.23 sent for Contract Name ABC. (i.e. raised by 23%)
Lower prices can be sent with a multiplier less than 1, i.e. '''ABC*0.85''' will send a price 85% of the normal price (i.e. lowered by 15%)
To convert the price of bookings imported add a * after the multiplier, for example 12345678*1.23* will divide the price of the booking by 1.23.
You can also use currency conversion template variable. All currencies supported by the booking page currency selector can be used.
