Can I work with several currencies at the same time?
You can switch between currencies (see other FAQ article on switching between currencies) but you cannot work with multiple currencies at the same time.
Workaround: As quotes and invoices are issued in Word, you can simply replace your money values in your base currency by values in the respective foreign currency (or add the equivalents in the foreign currency).
Working with several currencies in one database would be quite complex as currencies are changing on a daily basis which is why exchanges rates would have to be stored for a consolidated result in the base currency. However this feature is registered for future implementation.
