Peppol FAQ: Everything you need to know about mandatory e-invoicing in 2026

What exactly is Peppol?

Peppol stands for Pan-European Public Procurement Online. It is a network that enables secure exchange of electronic invoices between businesses. It works a bit like email, but specifically for business documents, with extra security and a fixed structure. What makes Peppol special is that it is a European standard, so companies from different countries can exchange electronic documents smoothly without worrying about different formats or systems.

When does e-invoicing via Peppol become mandatory?

From 1 January 2026, electronic B2B invoicing via the Peppol network will be mandatory in Belgium. The main reasons for this decision:

Efficiency and cost savings

Manual invoice processing costs time and money. E-invoicing automates the process, leading to fewer errors and lower administrative costs. Research shows companies can save up to 60% per invoice with electronic processing.

Environmental benefits

Less paper means less environmental impact. Switching to e-invoicing helps companies contribute to sustainability.

Fighting fraud

E-invoicing makes invoice fraud harder because data is stored and exchanged in a structured way. This helps the government combat VAT fraud.

What does this mean for your business?

If you run a cleaning company in Belgium, from 2026 you must be able to send and receive electronic invoices via the Peppol network. This applies to all B2B transactions, regardless of company size.

This means you need to:

• Use software that supports Peppol
• Apply for a Peppol ID
• Adapt your administrative processes
