Switching to e-Invoicing: a step-by-step guide

The Turkish Revenue Administration (GİB) mandates e-Invoice (e-Fatura) for businesses above set revenue thresholds. Even below the threshold, you’ll typically need e-Arşiv or e-SMM. Here’s a step-by-step guide.

1. Identify which system you need

• e-Fatura: Between registered e-Fatura users. Mandatory if previous year revenue ≥ TRY 3M.
• e-Arşiv: For invoices to non-e-Fatura recipients. Used alongside e-Fatura once you’re above the threshold.
• e-SMM: Electronic equivalent of the professional-services receipt. Mandatory for lawyers, doctors, CPAs, etc.
• Sector-specific obligations may also apply (e-Müstahsil, e-İrsaliye).

2. Get a digital seal

To issue e-documents you need a digital seal (legal entities) or e-signature (individuals). Apply via ŞirketOn — delivered in 5–7 business days.

3. Apply for e-Invoice

Application is done via the GİB Portal. With ŞirketOn integration we file on your behalf — you only install the application certificate once your seal arrives.

4. Pick an integrator

Three options:

• GİB Portal: Free, manual data entry — for low volume.
• Private integrator: Monthly/annual subscription with professional UI, automation, reporting.
• Self-built integration: Direct GİB integration if you have engineering capacity.

ŞirketOn’s pre-accounting module is a private integrator — issue e-Fatura, e-Arşiv, and e-SMM from one panel.

5. Issue your first invoice

1. Enter customer info (tax ID or national ID).
2. Add product/service, quantity, VAT rate.
3. Preview, approve, submit to GİB.
4. The approved invoice is delivered as PDF + XML to both parties.

6. Storage requirements

e-Documents must be stored for 10 years. ŞirketOn handles archival automatically; you can download anytime.

ŞirketOn e-Invoice package

All ŞirketOn incorporation packages include integrator rights by default. Run formation, pre-accounting, invoicing, and reporting from one platform.

Tip: Apply at least 7 business days before your switchover deadline — there are last-minute delays during busy periods.
