Fiskalizacija 2.0 ready

Croatian invoicing, fiscalized and filed.

Clava Billing issues your invoices, fiscalizes them with the Tax Administration, builds your eRačun in UBL 2.1 CIUS-HR, and keeps the monthly reporting on schedule — for companies selling in Croatia, the EU and worldwide.

No card required. Your data stays yours.

Everything the law asks of you, in one place

From the moment an invoice is issued to the moment it is reported.

B2C fiscalization

Every consumer invoice is signed and reported to the Tax Administration at issuance — ZKI, JIR and the verification QR code on the printed invoice. From 2026 this applies regardless of how the invoice is paid, bank transfers included, and the platform handles all of them.

eRačun for B2B and B2G

Domestic business invoices are built as UBL 2.1 in the CIUS-HR profile, validated against the HR-BR business rules before they leave the platform, delivered through your information intermediary, and fiscalized with EvidentirajERacun.

Correct VAT, every time

A decision engine picks the treatment per invoice: domestic VAT, EU reverse charge with VIES verification, OSS for cross-border consumers, or out of scope — with the location evidence and the legal clause recorded on the document.

Monthly reporting on time

Payment collections are reported by the 20th, your VAT return and I-RA book are prepared from real invoice data, and a deadline calendar e-mails you before anything is late.

Offers that become invoices

Send a quote with a validity period and a payment link. When the customer pays, the legal invoice is issued automatically with the tax decision taken at the moment of payment — the tax point the law asks for.

Your accountant will thank you

One-click monthly export with invoice CSVs and the original eRačun XML files, plus camt.053 bank statement import that matches incoming payments to open invoices.

Fiskalizacija 2.0

What changes in 2026, and what we do about it

eRačun becomes mandatory between businesses

From 1 January 2026, VAT-registered companies must issue and receive electronic invoices for domestic B2B transactions, and fiscalize them.

We build, validate and fiscalize the outgoing eRačun as part of issuing the invoice.

Consumer invoices are fiscalized regardless of payment method

The old cash-only rule is gone: every invoice issued to a consumer is fiscalized, including invoices paid by bank transfer.

Fiscalization is driven by who the customer is, not how they paid — so nothing slips through.

Questions people ask

Do I need a FINA certificate?
Yes — fiscalization messages are signed with your own application certificate. You upload it during onboarding, and we warn you 60 days before it expires.
Can I sell to customers outside Croatia?
That is what the tax engine is for. EU business customers get reverse charge after their VAT ID is verified in VIES, EU consumers are handled under the OSS threshold rules, and customers outside the EU are treated as out of scope.
Does it work with my accounting software?
The monthly export produces invoice and credit-note CSVs alongside the original eRačun XML files, so your accountant can import the period in one step.
What happens to my data if I leave?
Your invoices, PDFs and XML files are yours. Export the full archive at any time — including after you cancel.
Do you use the platform yourselves?
Yes. Your subscription invoice from us is issued by this same platform, with the same fiscalization and eRačun pipeline your invoices go through.
