e-Fatura & e-Arşiv Setup in Zoho Books for Turkish Businesses (2026 Guide)

Türkiye's e-Fatura (electronic invoice) and e-Arşiv Fatura (electronic archive) regimes are mandatory for VAT-registered businesses over specific revenue thresholds. Integrating Zoho Books with GİB-approved entegratör services unlocks fully compliant invoicing with KDV automation. Here's the complete setup playbook.

When is e-Fatura mandatory in Türkiye?

GİB (Türkiye Revenue Administration) mandates e-Fatura for VAT-registered businesses meeting specific criteria: turnover thresholds, sector-specific rules (fuel, alcohol, tobacco, internet trade), or customer-side requirements. e-Arşiv applies to invoices sent to non-e-Fatura registered customers. Most growing KOBİ businesses cross e-Fatura thresholds within 2-3 years, better to architect for it from day one with Zoho Books than retrofit later.

Configure Zoho Books for Türkiye e-invoicing

Settings → Türkiye Compliance → enable e-Fatura. Select your GİB-approved entegratör (special integrator service): Logo, FİT, Uyumsoft, BulutDestek and others. Enter your VKN (Vergi Kimlik Numarası, Tax ID), connect your entegratör API credentials, and configure KDV rates (1%, 10%, 20%) per product/service. Zoho Books validates VKN format and pushes signed XUBL invoices to the entegratör, who routes to GİB for B2B clearance or to e-Arşiv for B2C archiving.

Daily operations and GİB compliance

B2B invoices: Zoho Books generates the invoice, entegratör signs and sends to GİB, GİB validates and forwards to recipient, typical roundtrip 1-3 seconds. B2C: e-Arşiv Fatura is generated, signed, archived with GİB and a copy sent to customer email or printed with QR code. Monthly: KDV declarations (KDV-1, KDV-2) reconciled from Zoho Books reports. Annual: Defter-Beyan compatibility for full digital bookkeeping.
