Edit the currencies of your store under Administration → Currencies.
As a rule, multiple currencies serve to display prices on the storefront. Payments are usually accepted in the store primary currency only.
However, if your payment gateway is configured to accept payments in different currencies, customers who use this gateway will be charged in an alternative (not primary) currency.
The order total will be calculated according to the store currency exchange rate that you define here.
All prices you enter in the Administration panel are assumed to be in the primary currency. CS-Cart & Multi-Vendor use primary currency for all calculations. When necessary, the results of those calculations are converted to the selected currency according to the specified exchange rate.
Name—the name of the currency as it appears on the storefront (USD, Euro, etc.)
Code—the unique code of the currency.
Primary currency—the primary currency of your store.
Rate—the exchange rate to convert store prices and costs from the primary currency to this currency.
In the example above, the primary currency is the American dollar, and the values in the Rate field define, how many dollars there are in one Euro and in one British pound.
Sign—the currency symbol.
After sum—if you enable this setting, the currency symbol will appear after the price. Otherwise, it will appear before the price.
Ths sign—the symbol that separates thousands.
Dec sign—the symbol that serves as the decimal mark.
Decimals—the number of digits after the decimal mark.
