bizBox (ZZI) is entering the Croatian market: 30 years of experience and technology for a new wave of digital account exchange

The company ZZI doo, under whose brand bizBox operates as a leading provider of solutions for electronic business messaging, announces its entry into the Croatian market.

After more than 30 years of continuous work in Slovenia and neighboring countries, bizBox comes to Croatia with a clear goal: to offer not only e-invoices, but full EDI chain support and internationally interoperable business.

Croatia is preparing for a new phase of fiscalization and digitalization: according to an article published in Poslovni dnevnik, from January 1, 2026, all companies operating in the VAT system will have to exchange e-invoices with other business entities, and from 2027, companies outside the poslovni.hr VAT system will also have to exchange e-invoices with other business entities. This transition opens up significant opportunities for service providers, but also poses a challenge for companies that have yet to harmonize all this.

In such a context, bizBox brings the following advantages:

• More than three decades of experience in developing digital business solutions.
• Support for the entire EDI value chain — not only sending/receiving e-invoices, but integrations, archiving, international exchange.
• Focus on security and compliance with regulations (including fiscalization, e-invoices, international standards).
• Scalability for large and small companies: from domestic invoices to international chains.
• Local presence/region with understanding of the CEE and Southeastern European markets.

Several IT intermediaries and e-invoicing service providers already operate on the Croatian market, but bizBox sees its entry as an opportunity for differentiation:

“We are not just coming as another e-invoice provider. We aim for a complete solution that supports digital business transformation, EDI, international flows and future fiscalization 2.0 requirements.”, comments Peter Zorko, director of ZZI.

For Croatian companies preparing to transition to mandatory digital exchange of invoices, bizBox also offers specialized services: consulting on compliance with new deadlines, migration of existing systems, integration with accounting services, and support for international interoperability (e.g. if they also do business with neighboring countries or within the EU).

Entering the Croatian market is a logical step in ZZI’s strategy for the region: with already established clients in Slovenia and beyond, the company now wants to expand its reach into markets that are rapidly digitizing their businesses. The e-invoice service, as well as broader EDI solutions, are becoming increasingly important as Croatia introduces additional regulations and expects significant growth in exchange volumes – according to estimates, the number of e-invoices between companies could grow five to tenfold in the next two years.
