Peppol & E-invoicing in Belgium
E-invoicing has been mandatory for B2B transactions in Belgium since January 2026, turning a legal obligation into an opportunity to make invoicing more secure, efficient and automated. EY helps you meet legal requirements, optimize your systems and processes, and future-proof your invoicing operations through a smooth and well-supported transition.
What EY can do for you
The Belgian mandatory e‑invoicing reform marks a major shift in how businesses exchange invoices. From 2026 onward, companies must issue and receive structured e‑invoices through the Peppol-network, using formats compliant with European standards. While the reform introduces new legal obligations, it also offers opportunities to strengthen digital processes, increase efficiency, and improve the quality and security of financial data.
Implementing e‑invoicing requires more than installing new software. It impacts a company’s administrative workflows, internal controls, accounting systems, supplier and customer communication, and broader digital strategy. Many organizations also operate in multiple countries with different e‑invoicing rules, making a coordinated approach essential. EY helps you navigate these complexities by combining tax, technology, and process expertise.
