The type of fiscalization system which is incorporated in Croatia represents a specific type of online fiscalization. There are many mandatory requirements for the retailers which need to be addressed before the retailer can start with business activities. The control mechanism implemented by the Tax Authority gives a high level of supervision and analysis of the transaction data.
Croatia
Online authorization is the core of Croatian fiscal law. Each receipt has to be sent to the server of the Tax Authorities and that is done from the POS which needs to have Internet access. The central server returns certain identification keys, which have to be printed on the receipt. When there is no Internet connection, customer services are in progress even though retailers are offline. In those situations, the reauthorization has to be performed later for each transaction, within a period of 48 hours.
