The Setup>Main >> Account>Currencies Tab (Gold & Platinum Plans).
Each reservation can be assigned a different currency. Reports will convert to the base currency when summing values and display both when individually shown.
When using Online Quoted Booking™ other currencies can be quoted either alone or at the same time as the base currency o the Requests page. If you check the "Always Include in Quote" checkbox for a currency then it will be included in every quote, otherwise it will be included when that currency is selected in the request itself. If more than one currency is quoted then the traveler would choose the one they want when completing the Booking Form online. All rates are calculated from the base currency using the exchange rate provided here.
Choose the currencies that you offer rates in here along with your own exchange rate compared to the base currency. If your base rate is USD and you take GBP then the exchange rate will be larger than 1 as there are more USD to the UKP. Use the rate to build in some exchange "fees" by skewing the rate to charge a little more for foreign currencies.
When embedding the rates table on your website, these other currency rates will be displayed at the same time.
