Shopify works in virtually every country and every currency. With Grid, you can sell internationally with ease by using the currency converter. This displays as a dropdown menu in the header of your storefront, allowing customers to dynamically update their prices throughout your shop.
Activate the currency converter
After activating the converter by checking Enable currency conversion, you can choose which currencies are supported and how they're displayed.
Select a format option
Under Format, you can choose whether or not to display the currency acronym on product and collection pages (e.g. $10.00 CAD vs. $10.00).
Configure currencies to support
Under Supported currencies, you can select which currencies you want to allow users to display when browsing your store. Be sure to use the country's ISO currency code, and separate each with a space. Note that exchange rates used by Shopify are refreshed twice a day based on rates at XE.com
Assign default currency
You'll also set the Default currency on this page. This is the currency that will display when a user first lands on your site, before they have had a chance to use the currency customizer. This is different from your store's Operating currency, which is the currency you use to process orders.
You can set your operating currency in the Shopify admin under Settings > General > Store currency > Change formatting.
