Shopify works in virtually every country and currency. With Pixel Union themes, 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.
Enabling the currency converter
Activate the feature by checking Enable currency conversion in the Theme settings.
Selecting format and supported currencies
Under Format, control whether or not to display the currency acronym on product and collection pages (e.g. $10.00 CAD vs. $10.00).
Under Supported currencies, 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
Setting a default currency
Set the Default currency on this page. This is the currency that will display when a customer first lands on your site (before they have had a chance to use the currency customizer). This may be different from your store's Store currency, which is the currency you use to process orders.
You can set your Store currency in the Shopify admin under Settings > General > Store currency > Change formatting.
