Frequently asked questions about Peppol: Everything you need to know about mandatory e-invoicing in 2026

The future of business invoicing in Belgium

From 2026, the way companies in Belgium and Europe exchange invoices will change. The government has decided that electronic invoicing via the Peppol network will be mandatory for all B2B transactions. At Buttons for Cleaners we are already preparing for this change. In this article we explain what this new legislation entails and how we adapt our software accordingly.

What exactly is Peppol?

Peppol stands for Pan-European Public Procurement Online. It is a network that ensures the secure exchange of electronic invoices between companies. It works a bit like email, but specifically for business documents and with extra security
and a fixed structure. The special thing about Peppol is that it is a European standard. This means that companies
from different countries can easily exchange electronic documents, without having to worry about different formats or systems.

When will e-invoicing via Peppol become mandatory?

The Belgian government has made it mandatory for B2B invoicing as of January 1, 2026:

Efficiency and cost savings

Manual processing of invoices costs time and money. With e-invoicing, this process is automatic, leading to fewer errors and lower administrative costs. Research shows that companies can save up to 60% per invoice with electronic processing.

Environmental benefits

Less paper means less impact on the environment. By switching to e-invoicing, companies contribute to sustainability.

Combating fraud

E-invoicing makes it more difficult to commit fraud with invoices, because all data is stored and exchanged in a structured manner. This helps the government combat VAT fraud.

What does this mean for your company?

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

• Must use software that supports Peppol
• Must apply for a Peppol ID
• You need to adjust administrative processes
