e-invoicing in Belgium
Belgium is standardizing electronic invoicing across both public and private sectors. Suppliers to the government must already send e-invoices in a structured format (typically Peppol BIS Billing 3.0) in line with EU requirements, and from 1st of January 2026 e-invoicing became mandatory for most B2B transactions between Belgian VAT-registered companies. The Peppol network is the primary channel for exchanging structured invoices, and Belgium is progressing toward broader digital reporting and compliance with EU ViDA initiatives
When registering a new Belgium company via the API, the Belgium CBE/KBO number must be used as the company identifier. At the moment there is no way to authorize the companies other than having them as from a vendor having their KYC approved by us. Contact our support for KYC approval.
- CBE = Crossroads Bank for Enterprises (English translation of Banque-Carrefour des Entreprises)
- KBO = Kruispuntbank van Ondernemingen (Dutch name for the same thing)
For B2B and B2G, sending in Belgium is currently supported in the following priority order: through Maventa’s internal network, and through the Peppol network. Email and postal delivery (print) are also available as fallback options. Printing is handled in Finland, and all postal deliveries are sent from Finland.
For B2C, invoices are delivered via email and print only.
In Belgium, companies can receive invoices through different channels. If a company has activated e-invoice receiving, they can receive invoices via Maventa’s internal network. Additionally, if the company is registered with Peppol, Peppol receiving is available. Companies with the scanning activated can also receive scanned invoices.
CBE number is the official and recommended identifier for Belgian companies on Peppol, and it is also what the Belgian Peppol Authority expects to be used when registering Belgium companies to Peppol.
| Address Type | Description | Example address | Activation Requirement |
