This is Lana from Shopify. I see you're looking to start selling in multiple currencies so I wanted to help you out here.
It is important to note that selling in multiple currencies is only possible if your store is using the Shopify Payments gateway. If you are not currently using Shopify Payments, you can check this help doc here to see if your country is on the list of supported regions. In the case that it is supported, you can then take these steps to set it up.
Once you're all set up with Shopify Payments, the next step is to add the currencies that you would like to sell in. For this, you will need to follow these steps:
You will then need to look into adding a currency selector as most themes don't have them, and your customers need a way to be able to switch to their local currency on your store. For this I recommend you check out our Geolocation app, but you can also work with an Expert to get this custom coded for you.
You can review the steps that I outlined here as well as some additional info in our help doc on Selling in Multiple Currencies, but also feel free to ask me any questions here and I will be happy to help you out!
I see, it looks like this feature is not yet available for you. While you're not able to sell in multiple currencies at the moment as Shopify Payments is not available to you, I would recommend you keep an eye on our Changelog. That is where you will see an update on Shopify Payments if it becomes available in your region in future.
If Shopify Payments becomes available for you, you will also be able to see that on our Payment Gateways page here, you will just have to select your region from the list below to view it!
