What is Peppol, in one sentence?
Peppol (Pan-European Public Procurement OnLine) is an international network standard that lets businesses exchange structured electronic documents, such as invoices, directly between accounting systems via certified access points — not a piece of software you install, and not a single company you sign up with. Belgium uses the Peppol network as the mandatory channel for B2B e-invoicing; other countries, including France, use different national infrastructure for their own e-invoicing mandates.
Is Peppol registration mandatory in Belgium, and since when?
Yes: since 1 January 2026, B2B invoicing between Belgian VAT-registered businesses must use structured electronic invoices transmitted over the Peppol network — a plain PDF or Word invoice by email no longer satisfies the legal requirement for this type of transaction. The obligation covers nearly all VAT-registered Belgian businesses issuing invoices to other Belgian VAT-registered businesses, regardless of size, including businesses under the small-enterprise VAT exemption scheme.

A tolerance period after the launch date allowed some flexibility for businesses not yet fully operational; that period ended 31 March 2026. Since 1 April 2026, the general fine ladder documented by FOD Financiën applies to established infringements: €1,500 for a first infringement, €3,000 for a second, and €5,000 from a third — stated here as general, publicly documented regulatory information, not as an assessment of any specific business's situation.
How many Belgian businesses are actually registered?
According to VRT NWS reporting on FOD Financiën figures, around 940,604 of the 1,191,956 businesses in scope were registered by late January 2026 — an adoption rate of roughly 79%. FacturaDesk's own analysis, based on a direct comparison of Belgian Crossroads Bank for Enterprises (KBO/BCE) open data against the public Peppol directory (July 2026), counts 1,198,411 Belgian businesses currently registered under their KBO/BCE number, against 716,555 active Belgian businesses (upper bound, excluding medical and financial-sector activity codes) not yet appearing in the directory.

How does a Belgian business register for Peppol?
Registration means your business is assigned a Peppol ID linked to a certified access point, making it discoverable in the public Peppol directory for sending and receiving structured e-invoices. In practice, most Belgian businesses register one of three ways: through accounting software with built-in Peppol support (often free or low-cost), through their accountant's own access point, or through a done-for-you onboarding service.
- Check first. A business can already be registered via its accountant's access point without appearing under its own name in a casual search — verify with a proper lookup rather than assuming.
- Compare software options if you have time: many Belgian accounting packages include Peppol at no extra cost, and standalone access points exist from roughly €0–30/month.
- Or have it done for you if you'd rather not compare software and configure it yourself — done-for-you providers handle the full access-point registration and configuration for a fixed fee.
How can I check if my Belgian business is already registered?
The fastest way is a direct lookup in the public Peppol directory by company name or KBO/BCE number. FacturaDesk runs a free, no-signup Peppol lookup tool for exactly this — available in Dutch and French, the two languages Belgian search behavior actually uses for this topic.
How is Belgium's mandate different from France's e-invoicing reform?
Belgium's mandate runs on the Peppol network with a single national go-live date of 1 January 2026 for B2B transactions between Belgian VAT-registered businesses; France's e-invoicing reform is a separate legal framework built around registered private platforms (PDPs) and the Chorus Pro infrastructure, with its own distinct rollout timeline for French businesses. The two mandates are not interchangeable: a business searching for French e-invoicing obligations should consult French official sources, not this Belgian-specific page, and vice versa.
Frequently asked questions
Does this Belgian mandate apply to non-Belgian companies invoicing Belgian clients?
The core obligation targets Belgian VAT-registered businesses invoicing other Belgian VAT-registered businesses. Foreign companies without a Belgian fixed establishment fall outside the core scope in most cases — verify your specific situation against efactuur.belgium.be or a Belgian accountant.
Is Peppol the same thing in Belgium and France?
The Peppol network itself is international and used in dozens of countries, but Belgium's legal mandate specifically requires it for B2B e-invoicing. France's own e-invoicing reform is a different national mandate that does not rely on the same registration path — do not assume Belgian Peppol registration satisfies a French obligation, or the reverse.
What happens if a Belgian business isn't registered yet?
Since the tolerance period ended 31 March 2026, the general fine ladder (€1,500 / €3,000 / €5,000 for successive established infringements) applies as a matter of public regulatory record — this is general information, not an assessment of any specific business. Not appearing in the public directory is also not, by itself, proof of non-compliance, since accountant-managed registrations can appear differently.
Where can I read the full rules in Dutch or French?
See the Dutch pillar article Is Peppol verplicht in België? or the French equivalent Peppol obligatoire en Belgique for the complete, natively written breakdown of scope and exceptions.
