You only can change the display currency on your Invoice. The display currency means that the currency is displayed to your customer. This is an estimate calculation of the default currency price (IDR/PHP/USD) if converted to your selected display currency. Note: the charge will still be in your default currency (IDR/PHP/USD).
To customize the display currency on your invoice, go to Customize Invoice setting and choose Invoice settings. You can control what currency will be displayed on your Invoices, then click the Save button after you choose the display currency you want.
