In short: We manage your e-Invoice, e-Archive Invoice and e-Ledger obligations end to end, from initial setup to monthly period approvals.

Turkey’s Revenue Administration electronic document systems have become mandatory for taxpayers above certain revenue and sector thresholds. Transitioning to e-Invoice, e-Archive Invoice and e-Ledger is a technical process requiring the right application, a financial seal, and integration with your accounting software.

What’s Included

e-Invoice and e-Archive Invoice setup: From your registration date, we handle the applications needed to move onto the e-Invoice and e-Archive Invoice system, and help you choose between an integrator or the Revenue Administration’s own portal based on your transaction volume.

e-Ledger certificate process: For taxpayers required to keep e-Ledgers, we make monthly ledger generation, certificate retrieval, and on-time upload to the government system a standard part of our monthly bookkeeping cycle.

Integration advisory: If you already use accounting or pre-accounting software, we ensure it integrates correctly with the e-document systems, preventing data mismatches.

Why It Matters

Failing to meet e-Invoice and e-Ledger obligations on time and in full can lead to special irregularity penalties. Delays in the certificate upload process can also call the validity of your books into question during a future tax audit. That’s why we manage e-document processes with the same discipline as periodic tax filings.

How We Support This

In our first meeting, we assess your current invoicing and accounting infrastructure and clarify which e-document system (e-Invoice, e-Archive, e-Waybill) is mandatory or beneficial for you. We then run the setup process and fold monthly certificate and approval tracking into our regular bookkeeping service.

Fit

Who Is It For?

A Good Fit When

  • Taxpayers whose gross sales exceed, or are expected to exceed, the threshold set by the Revenue Administration
  • E-commerce businesses selling goods or services online
  • Newly formed companies that want to start with an e-document setup from day one
  • Businesses choosing between the GİB Portal and a private integrator
  • Businesses that want to connect their existing pre-accounting software to the e-document system

When a Different Route Is Needed

  • Private integrator services are provided only by firms authorised by the Revenue Administration; we support you in choosing an integrator and managing the transition.
  • Custom coding for ERP or e-commerce platform integrations is the job of a software company; we handle the accounting-side setup and controls.

FAQ

Frequently Asked Questions

What is the difference between e-Invoice and e-Archive Invoice?

An e-Invoice is issued only between two registered e-Invoice users and is delivered to the buyer through the Revenue Administration system. If the buyer is not an e-Invoice user (a consumer or a business not registered for e-Invoice), the same invoice is issued as an e-Archive Invoice. Which type applies depends on whether the buyer appears on the list of registered e-Invoice users at the time of sale.

Am I required to switch to e-Invoice?

The obligation arises from the gross sales thresholds and certain sectors listed in Tax Procedure Law General Communiqué No. 509; the thresholds are updated over time. As a general rule, e-Invoice must be used from the beginning of July of the year following the year in which the threshold is exceeded. Taxpayers without an obligation can switch voluntarily; we decide on this together based on your transaction volume and customer base.

When must e-Ledger certificates be uploaded?

e-Ledger certificates (berat) are uploaded to the Revenue Administration system by the end of the third month following the relevant month; for example, the January certificate is due by the end of April. For corporate taxpayers, the deadline for the certificates of the final months of the year is tied to the corporate tax return deadline. Failing to upload a certificate on time puts the validity of the ledger at risk and can lead to penalties.

Do I need a financial seal or an e-signature?

Legal entities (limited and joint-stock companies) use a financial seal (mali mühür) issued by TÜBİTAK Kamu SM for e-Invoice and e-Ledger. Individual merchants and self-employed professionals may use a qualified electronic certificate (e-signature) instead. When working with a private integrator, signing is often handled by the integrator.

What happens if I issue a paper invoice while registered for e-Invoice?

If a taxpayer obliged to use e-Invoice issues a paper invoice to another registered e-Invoice user, the invoice is deemed not to have been issued. This triggers a special irregularity penalty under Article 353 of the Tax Procedure Law for both the buyer and the seller, and the buyer's VAT deduction becomes questionable.

Can I object to an e-Invoice I have received?

An e-Invoice sent under the commercial invoice scenario can be rejected through the system within 8 days of receipt, in line with Article 21 of the Turkish Commercial Code. Under the basic invoice scenario, there is no rejection option in the system; the objection is made in writing, for example via a notary, registered electronic mail (KEP) or registered letter.
