Savannah here from the Shopify Guru Team.
Shopify Payments currently isn't available in Croatia (yet!), but you can definitely choose from these available payment gateways instead: Croatian Payment Gateways. Don't hesitate to reply back if there's anything I can clarify. Our guru team also provides 24/7 live support here: https://help.shopify.com/questions.
I was wondering if there are any updates on when will Shopify Payments be available in Croatia. I know this topic is almost 3 years old but still nothing changed and its really stopping a lot of businesses here because there is no "easy" way to accept cards in Croatia. The only way right now is through third party payment gateway providers that have very strict rules on who they accept. Thanks in advance and I hope you understand this size of this problem.
Thanks for checking in on this. At this time there is no timeline for launching Shopify Payments in Croatia. While I can certainly understand the wait can be long, we are in the process of getting Shopify Payments launched in as many countries as possible.
When Shopify Payments becomes available in Croatia, our team will be sure to reach out via email to let you know.
