Sprout has the ability to conduct transactions with vendors in a foreign currency.  This allows the user to see costs converted to their currency but purchased and paid for in the vendor's currency.

The exchange rates are adjustable and historical reporting is also available via the Audit log.

To use multiple currencies you must contact support to enable the feature.  This document explains the processes to use multiple currencies.

Exchange rates are entered in terms of how much an alternate currency buys one unit of the default currency.
