PEPPOL in SIX ERP enables standardized, fully electronic exchange of invoices and credit notes with customers, suppliers, and public administrations through the Pan-European PEPPOL network. It is designed to support EU e-invoicing requirements while reducing manual work and errors.
PEPPOL (Pan-European Public Procurement On-Line) is an international network and set of standards for exchanging electronic business documents such as invoices and credit notes. Instead of emailing PDFs or sending paper, organizations exchange structured, machine-readable documents through certified access points.
Key concepts:
Standardized formats – PEPPOL uses the Peppol BIS Billing 3.0 specification based on UBL (Universal Business Language), aligned with the European e-invoice standard EN 16931.
Secure, interoperable network – Every participant connects once to a PEPPOL Access Point and can then exchange documents with all other participants on the network (“connect once, reach many”).
Cross-border by design – Originally created to simplify public procurement across European countries, now widely used for B2G and increasingly B2B e-invoicing.
PEPPOL is relevant for:
Businesses selling to public sector bodies (B2G)
Many EU countries either mandate or strongly recommend PEPPOL/EN 16931-compliant e-invoicing for invoices sent to public administrations.
Companies exchanging invoices with other businesses (B2B)
PEPPOL is increasingly used for domestic and cross-border B2B e-invoicing, driven by national mandates and the need to automate high-volume transactions.
Organizations operating across borders
Groups working with customers or suppliers in multiple countries benefit from a single, consistent way of sending and receiving invoices and credit notes, rather than managing different formats per country.
Within such organizations, PEPPOL primarily serves:
Finance and accounting teams
Shared service centers and SSC/AP teams
Public sector suppliers and contractors
Larger enterprises onboarding many suppliers or customers
The PEPPOL module in SIX ERP focuses on the core financial documents needed for everyday billing and corrections.
Customer invoices
Standard sales invoices issued to customers or public sector entities, sent as structured e-invoices over the PEPPOL network.
Customer credit notes
Corrections, refunds, and adjustments linked to previous invoices, sent as standardized PEPPOL credit notes.
Vendor invoices
Invoices you receive from suppliers over the PEPPOL network, in a structured format that can be automatically processed.
Vendor credit notes
Credits issued by your suppliers (for returns, corrections, or discounts), received as standardized PEPPOL credit notes.
All of these use structured electronic formats based on Peppol BIS Billing 3.0 / UBL, ensuring consistency with EU e-invoicing standards and national implementations.
Aligns with EU Directive 2014/55/EU on electronic invoicing in public procurement and the EN 16931 standard used across EU member states.
Helps prepare for national B2G and B2B mandates that require structured, PEPPOL-compatible invoices in many countries.
Result: your billing processes are aligned with current regulatory expectations and more resilient to upcoming e-invoicing obligations.
Structured data and automated validation shorten approval and payment cycles compared to paper or PDF exchange.
Recipients can integrate the invoice directly into their systems without manual re-keying, speeding up their processing and your cash collection.
Result: improved cash flow and fewer payment delays.
Standardized document structure reduces the risk of missing or inconsistent data.
Less manual entry means fewer typos, mismatched totals, and incorrect references.
Result: fewer corrections, disputes, and credit notes — and less time spent resolving them.
Eliminates printing, postage, and physical archiving for invoices and credit notes. (European Commission)
Reduces staff time spent on manual data entry, document matching, and chasing lost invoices.
Result: lower operating costs per invoice and better scalability as volumes grow.
Every document sent or received over PEPPOL has a clear, machine-readable record and lifecycle.
Data is consistent and standardized, making it easier to report, audit, and analyze.
Result: simpler compliance checks, clearer audit trails, and better financial visibility.
One connection to the PEPPOL network allows you to exchange documents with many partners (public and private) across countries, via their chosen access points.
Avoids maintaining separate formats or custom connections for each major customer or supplier.
Result: easier onboarding of new partners and smoother international expansion.
Switching from paper to digital documents reduces paper usage, printing, and physical logistics associated with invoicing.
Result: smaller environmental footprint for your billing processes.
Within SIX ERP, the PEPPOL module acts as the e-invoicing gateway:
Outgoing: It converts your invoices and credit notes into standardized PEPPOL documents and delivers them to your customers or public authorities via the network.
Incoming: It receives standardized invoices and credit notes from suppliers and makes them available for further processing and financial control.
