Frequently asked questions on Peppol: Everything you need to know about mandatory e-invoicing in 2026
The future of business invoicing in Belgium
Starting in 2026, the way companies in Belgium and Europe exchange invoices will change. The government has decided that electronic invoicing via the Peppol network will become 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 means and how we are adapting our software to it.
What exactly is Peppol?
Peppol stands for Pan-European Public Procurement Online. It is a network that provides secure exchange of electronic invoices between companies. It works a bit like e-mail, but specifically for business documents and with extra security
and a fixed structure. What is special about Peppol is that it is a European standard. This means that companies
from different countries can start exchanging electronic documents without problems, without having to worry about different formats or systems.
When will e-invoicing through Peppol become mandatory?
The Belgian government has made it mandatory to make B2B invoicing mandatory as of Jan. 1, 2026:
Efficiency and cost savings
Manual processing of invoices costs time and money. With e-invoicing, this process is automated, resulting in 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.
Fraud Prevention
E-invoicing makes it more difficult to defraud invoices because all data is stored and exchanged in a structured way. This helps the government counter VAT fraud.
What does this mean for your business?
If you run a cleaning company in Belgium, as of 2026 you must be able to send and receive electronic invoices via the Peppol network. This applies to all B2B transactions, regardless of the size of your company.
This means that you:
- Need to use software that supports Peppol
- A Peppol ID must apply for
- Need to adjust your administrative processes
