Understand the basics

What is Peppol?

Peppol (Pan-European Public Procurement Online) is a standardised European network for exchanging electronic business documents between companies. It is based on the structured UBL 2.1 format, an XML file readable by accounting systems, tax authorities and invoicing software.

A network, not software

Peppol is an exchange infrastructure, like SWIFT for banks. Your invoicing software sends documents via this network to any participant.

UBL 2.1 format

Each Peppol invoice is an XML file structured according to the UBL 2.1 standard, containing all fiscal information required by the Belgian tax authority (SPF Finances).

Already mandatory in B2G

Since 2024, invoices to Belgian public authorities must go through Peppol. Since 1 January 2026, this obligation extends to all B2B transactions.

European recognition

Peppol invoices are recognised across the European Union. One format, one connection, for all your Belgian and European clients.

Frequently asked questions

Your questions about Peppol

When does Peppol invoicing become mandatory in Belgium?

Electronic invoicing via Peppol has been mandatory for public procurement (B2G) since 1 January 2024. For business-to-business (B2B) transactions, the obligation has applied since 1 January 2026 to all VAT-registered Belgian companies.

What is the UBL 2.1 format required by Peppol?

UBL 2.1 (Universal Business Language) is an international XML standard for commercial documents. Peppol requires this format to ensure all invoices are structured, machine-readable and compliant with Belgian tax requirements. Ledgerly generates this format automatically.

Is my company affected by the 2026 Peppol obligation?

Yes, if you are a VAT-registered Belgian company issuing invoices to other Belgian businesses (B2B). Freelancers, SRLs, SAs and all other legal forms are concerned. Only B2C invoices to private individuals are not covered by this obligation.

What are the penalties for non-compliance with Peppol?

SPF Finances can impose administrative fines for non-compliance with the electronic invoicing obligation. Non-compliant invoices may no longer be tax-deductible. Ledgerly ensures full compliance from day one.

Is Ledgerly certified for Peppol invoicing in Belgium?

Yes. Ledgerly uses B2Brouter, a certified Peppol Access Point, to send and receive invoices on the Peppol network. All invoices comply with the Belgian e-fff standard (SPF Finances) and UBL 2.1 format.

Do I need a Peppol identifier to send invoices?

To send an invoice via Peppol, your recipient must be registered on the Peppol network with a Peppol identifier (usually based on their Belgian VAT number). Ledgerly lets you enter this identifier in the client record and checks availability before sending.
