e-Fatura and e-Arşiv integration

Turkish invoices are electronic. We connect your system to a GİB-licensed special integrator and make every invoice type work end to end.

Not legal or tax advice. KOD16 is a technical implementation partner. Legal and tax opinions come from our partner Turkish accountants (mali müşavir) and law firms.

  • Buyer lookup by VKN/TCKN before every invoice: e-Fatura or e-Arşiv
  • UBL-TR mapping from your order or ERP data, incl. currency and exchange rate
  • Idempotent sending, status tracking and storage of the ETTN (UUID)
  • Cancellation, rejection and return flows
  • Archive and retrieval for the statutory period

Frequently asked questions

Is KOD16 an e-invoice integrator?

No. KOD16 is not a GİB-licensed integrator. We work with licensed special integrators and build the technical integration between your system and theirs.

Can invoices be in English?

Books and documents must be kept in Turkish (Tax Procedure Law Art. 215). Bilingual invoices are common, with Turkish as the legal text. Confirm with your accountant.

Can I invoice in EUR?

Invoices may show a foreign currency, but the TRY equivalent and the exchange rate used must also appear. Your accountant confirms which rate applies.
