Free Peppol: is it possible?

As a VAT-registered business you must be able to send and receive e-invoices via Peppol. That doesn’t have to be expensive. According to the government, there are enough affordable solutions for small businesses, and even free solutions on the market.

Is there a free government solution?

No. The government deliberately chose not to offer a central application for e-invoices between businesses. You choose software from a provider yourself. efactuur.belgium.be publishes a list of software solutions, but the government doesn’t recommend any product, and being on that list is neither a quality judgement nor a certification.

Mercurius is the electronic mailroom of public authorities: it’s for invoices to the government, not for invoices between businesses.

Free plans from providers

Below is what a few providers say themselves about their free plan, as we read it on their own websites on 25 October 2026. Prices and terms change often: check them before you choose. This list is not complete, we have no ties to these companies and don’t recommend any of them.

• Accountable: free Peppol registration. According to its own comparison table, the free plan lets you send and receive unlimited e-invoices.
• Let’s Peppol (BARGE vzw): free sending and receiving, open source, funded by donations and sponsors. Its own website says its uptime is not a legally binding commitment. You register with your eID and a card reader.
• Peppyrus: free plan with up to 100 outgoing Peppol messages a month, unlimited receiving and 200 MiB of storage. Peppyrus is introducing new plans from 1 November 2026 and says the free plan will stay.
• B2Brouter: free plan to send and receive up to 24 domestic invoices a year via Peppol, counted together.
• Billit: free sending. To receive e-invoices you need a paid licence, so the free plan alone is not enough.

What to look out for in a free plan

• Can you receive too? The obligation and the fine cover sending and receiving. Even if you only work for consumers, you must be able to receive e-invoices from suppliers.
• Are the limits enough? Some free plans count sent and received invoices together, or cap the number per month or per year.
• Can you keep your invoices? You keep invoices for 7 years. Check how much storage the plan includes and whether you can download your invoices. See How to keep e-invoices.
• Who is behind it? A free service without binding uptime commitments can be perfectly fine, but know what you’re choosing.

After registering, use the Peppol check above to see whether you can be found on the network.
