You can change the format in which a foreign amount prints on forms by editing the currency's format.
Note: QuickBooks displays foreign amounts in standard format so you won't see your changes until you print a form or transaction.
To edit a currency's format for printing
Go to the Lists menu and click Currency List.
Double-click the currency with the format you want to change.
Click Change Format.
Select your separator and decimal settings. To see how your changes affect the format, review the changes in the number that appears in the window.
