Start freeWhat it does
Invoicing, fiscalization and e-invoicing in one place
Fiskalizator issues and fiscalizes invoices - automatically from webshop orders or manually. For webshops, sole traders and small companies that need to issue and fiscalize invoices.
Fiscalization 1.0 - B2C fiscal receipt
A classic fiscal receipt with JIR and ZKI for sales to consumers, sent to the Tax Administration regardless of payment method.
Fiscalization 2.0 - e-invoice (a separate system)
The e-invoice is separate from the B2C receipt: a structured UBL invoice to an EU standard for B2B and B2G sales, sent via an information intermediary. Not the same as a fiscal receipt.
Webshop automation
Connect Shopify or WooCommerce and every paid order is handled automatically. By the buyer's OIB we pick the right document.
Manual invoices and offers
No webshop? Issue invoices, offers and recurring invoices manually - for sole traders and small firms, with e-mail sending and accountant export.
Aligned with EU regulation
The e-invoice uses the European EN16931 standard (UBL 2.1) with the Croatian CIUS, so B2B sales comply with EU e-invoicing rules. For webshops, Fiskalizator also adds the mandatory 14-day withdrawal button (EU Directive 2023/2673, in force from 19 Jun 2026).

Frequently asked questions
- Must I fiscalize my webshop from 2026?
- Yes. From 1 Jan 2026, Croatian fiscalization expands (Fiscalization 2.0): VAT payers issue and receive B2B/B2G e-invoices, and bank-transfer orders are fiscalized too - not only card/cash. Fiskalizator handles this automatically for Shopify and WooCommerce.
- What about bank-transfer (virman) payments?
- Those orders are fiscalized too. Fiskalizator issues a fiscal receipt (JIR/ZKI) regardless of payment method.
- How do I issue a B2B e-invoice to a company buyer?
- Automatically. If the order carries a valid Croatian OIB, Fiskalizator issues a structured e-invoice via your intermediary instead of a B2C receipt.
- Do I need a FINA certificate?
- For B2C fiscalization you need a fiscalization certificate (FINA or Certilia, .p12); a free FINA DEMO cert exists for testing. You upload it once; it is stored encrypted.
- What are JIR and ZKI?
- JIR is the unique invoice identifier assigned by the Tax Administration; ZKI is the issuer's security code. Both print on the fiscal receipt.
- Does it work on Shopify without a developer?
- Yes. Install the app from the Shopify App Store, paste the connection code, and the webhook sets itself up. No coding.
- Who charges for sending e-invoices?
- The Fiskalizator plan covers building, structuring and fiscalization; only e-invoice delivery is billed by the intermediary (~€0.08-0.25/doc) - transparent and separate.
- Am I obliged as a flat-rate obrt?
- VAT payers must issue e-invoices from 1 Jan 2026; others from 1 Jan 2027, with earlier receiving obligation.
- What are the penalties?
- Fiscalization non-compliance penalties range from EUR 2,000 to 200,000, so timely compliance matters.
- Do you support OSS / EU sales?
- Fiskalizator focuses on Croatian fiscalization and e-invoicing; for cross-border (OSS) get in touch.
