Hi there @MIXAS!
Don here from Shopify.
Thanks for reaching out to us here in the Shopify Community.
Generally speaking, as long as it is legal for you to sell where you are you can sell it via a store you create using Shopify.
If you're able to ship your goods or provide your services to those countries from where you are and you're aware of what you'd need to do to sell there you can go right ahead!
Could you let us know where your store is based (if you've set one up already) and, if you don't mind, let me know a bit more about your business and what you're looking to sell?
One thing to be aware of would be the currency you'd be selling in if you're looking to market to those different territories.
If you can confirm your store location I can share a list of the payment gateway providers available there and you can do some research into your options.
You mentioned you have existing customers in these places, so have you been selling elsewhere somewhere and you're looking to sell more online now?
I look forward to answering any questions you might have about using Shopify.
Hi there @MIXAS!
Don from Shopify once again.
Thanks for confirming that for me!
You can see your options in terms of payment gateways available in Turkey here.
Check out which of those options you might be interested in and check with them directly to see if they'd be able to support your business type specifically.
You may need to submit business and identification documents to whichever payment gateway you want to work with, though they'll be able to confirm their requirements for you.
Have you got an existing way you've been selling software or are you looking for a way to sell downloadable digital products from your store?
Don from Shopify once more.
That sounds great!
Be sure to let us know here if you have any other questions about using Shopify that we can help out with at any point.
All the best!
