Shopify has no built-in Croatian fiscalization, so merchants use an app that connects to the Tax Administration. Here is how it works and how to set it up.
Must a Shopify store fiscalize?
Yes. If you sell to Croatian consumers, every paid order must result in a fiscalized receipt (JIR and ZKI).
How it works
Order is paid -> Fiskalizator receives a webhook -> issues and fiscalizes the receipt -> JIR/ZKI and PDF go to the buyer. All automatic.
What you need - 15-minute setup
You need a FINA (or Certilia) certificate and a registered business unit. Install Fiskalizator from the Shopify App Store, paste the connection code, and you are live.
Frequently asked questions
- Does Shopify support it natively?
- No - you need an app that connects to the Tax Administration.
- Card orders?
- Automatically once the order is paid.
- B2B e-invoice on Shopify?
- Yes - if the buyer enters an OIB, an e-invoice is issued instead of a B2C receipt.
