Europe Peppol E-Invoicing Integration

Public-sector e-invoicing (B2G) has applied across the EU for years. National B2B mandates are now spreading:

• Belgium: B2B e-invoicing between Belgian VAT-registered businesses, with Peppol as the default exchange network.
• Germany: businesses must be able to receive structured e-invoices (XRechnung, EN 16931-conformant ZUGFeRD), with issuing obligations phased in by business size.
• France: a phased reform requiring businesses to receive and issue e-invoices and report data through approved platforms connected to the tax administration.
• Spain: Verifactu invoicing-software rules, SII reporting and a B2B e-invoicing mandate under the Crea y Crece law. See Spain e-invoicing.
• Poland: mandatory use of the national KSeF platform, introduced in phases.
• Others: more member states are following, and the EU ViDA package extends structured e-invoicing to cross-border trade.

Non-EU suppliers to European customers, including GCC and Indian exporters, increasingly receive requests to invoice via Peppol too. Check the official sources below for current dates and scope.

Peppol uses a 4-corner model: your system (corner 1) sends the invoice to your Access Point (corner 2), which looks up the receiver in the Peppol directory (SMP) and delivers it to the receiver's Access Point (corner 3), which passes it to the buyer (corner 4). Some countries add tax reporting on top, which is how 5-corner variants like the UAE's work.

National platforms such as KSeF work differently: invoices are submitted to a central government system, which assigns an ID and makes the invoice available to the buyer.

• Peppol BIS Billing 3.0 (UBL), the default Peppol invoice format based on EN 16931.
• XRechnung (UBL or CII) for Germany.
• ZUGFeRD / Factur-X hybrid PDF/A-3 with embedded XML for Germany and France.
• KSeF FA schema for Poland.
• National CIUS variants and validation rules (Schematron) maintained by each country.

We build a canonical invoice model from your ERP, with output modules per format and adapters for your Access Point or national platform. Inbound e-invoices are parsed and created as draft supplier bills for approval. Every document is validated with official rules before sending, and status is written back to the ERP.
