At any time, you can download the latest exchange rates from within QuickBooks. Downloading exchange rates is a free service that's included in QuickBooks. If you prefer to use your own exchange rates, you can manually enter those as well.
Note: QuickBooks downloads rates only for active default currencies and you can download rates only if your home currency is the US dollar.
Important: QuickBooks automatically overwrites existing exchange rates entered for the date you're downloading. If you need to keep an exchange rate while downloading, you'll need to make a note of the original rate and manually enter it after QuickBooks downloads the latest rates.
To do this task
Go to the Lists menu and click Currency List.
Click the Activities button at the bottom of the window and then click Download Latest Exchange Rates.
