The European Union is making B2B e-invoicing mandatory across member states. The Peppol (Pan-European Public Procurement On-Line) network is the backbone of this transformation. How should Turkish and European SMEs prepare?

What is Peppol?

Peppol is an international network that enables businesses to exchange electronic documents in a standardised format. Invoices, orders, and catalogs are transmitted in UBL 2.1 format through a certified access-point infrastructure.

Key advantages:

• Automated reconciliation — invoices land in the system, no manual entry
• GDPR-compliant data transmission
• Recognised in 40+ countries
• 90% fewer errors compared to paper invoicing

Invoicing European Customers from Outside the EU

If your business is based in Turkey or another non-EU country and you sell to European clients, you need Peppol-compliant format for those invoices. ISAR integrates with both standards:

1. Domestic sales → GİB / Hızlı Bilişim e-invoice (Turkey)
2. European sales → Peppol UBL 2.1 via DocNaut access point

How It Works in ISAR

Create Invoice → Select Customer Country → Format auto-selected
  ↳ Turkey    → GİB / Hızlı Bilişim
  ↳ EU States → Peppol UBL 2.1

ISAR automatically populates invoice IDs, tax data, and payment terms in the correct format. One-click send, PDF copy, and delivery confirmation included.

Conclusion

E-invoicing is no longer optional — it's a legal requirement for European business. With ISAR, you get a fully compliant, fast, and error-free invoicing workflow across Turkish and EU markets. Request a free demo →
