Selling in multiple currencies
To sell in multiple currencies, you need to have Shopify Payments enabled in your online store. When you sell to multiple countries or regions, your customers can view prices in your store, pay for their orders at checkout, and receive refunds in their local currency. You can choose to have prices converted automatically using the current market exchange rate, or converted manually using an exchange rate that you choose.
If your store is on the Shopify plan or higher, then you can also control prices in different countries or regions using international pricing.
If you're selling in multiple currencies, then you can add a country selector to your theme so that customers can select their local country or region so that your store displays their local currency.
