International.EInvoicing.Countries.Croatia

What Croatian electronic invoicing adds on top of the norms.

Croatia's Fiskalizacija 2.0 mandate has been live for domestic B2B since 1 January 2026. Invoices are UBL 2.1 exchanged over a five-corner Peppol-style network, so this package builds on International.EInvoicing.Peppol. What lives here is the thing a Croatian invoice cannot be written without: the OIB of both parties.

CroatianEInvoicing hrvatska = CroatianEInvoicing.Create();

EInvoice invoice = hrvatska.Invoice()
    .WithNumber("2026-0001")
    .IssuedOn(new DateOnly(2026, 9, 1))
    .WithBuyerReference("REF-2026-0001")
    .From(seller => hrvatska.Describe(seller, "69435151530", "Dobavljač d.o.o."))
    .To(buyer => hrvatska.Describe(buyer, "12345678903", "Kupac d.o.o."))
    .AddLine(line => line.WithItem("Savjetovanje").WithNetAmount(3000m).WithVat("S", 25m))
    .WithComputedVatBreakdown()
    .WithComputedTotals()
    .Build();

Describe checks the OIB against ISO/IEC 7064 MOD 11,10 before writing it, derives the VAT number from it, and puts it where both the legal registration and the electronic address are read from.

What this package does not do, and cannot:

  • The advanced electronic seal. Every Croatian invoice must carry one, backed by an OIB-linked certificate from an approved Croatian trust service provider. Signing is not in this library's scope.
  • The fiscalisation messages. Issuer and recipient each report to the tax administration in near real time. That is transport, which is permanently out of scope.
  • The KPD classification code every line must carry. Set it on Item.ClassificationCodes under list CG; the rules carry all 3 359 permitted codes, so a plausible one that is not among them is refused.

CIUS-HR 2025 is carried, profile and rules both. Its 74 assertions are not redistributable, so they are fetched rather than shipped: build/fetch-specs.sh national, then AddCroatianRulesFrom(...). With AddCroatianOperator(...) — which writes the time of issue and the operator's name and OIB, three terms EN 16931 has no words for — an invoice this package writes satisfies all 74.
