When it comes to updating an exchange rate, you have two options. You can either update the exchange rate manually or rely on QuickBooks Commerce to update it automatically. To set the option you prefer, first, go to the currencies page under ‘Settings.’
Select the currency you would like to manage.

A popup such as the one below should appear.

From the dropdown box ‘Exchange Rate’, you can select the method of updating that best suits you.

Note
If you decide to select “Use live exchange rate,” the rate will update every hour via openexchangerates.org.
Click Save, and you’re done!
