Starting January 1, 2026, Belgium is introducing mandatory electronic invoices (e-invoicing) for all B2B transactions between VAT-registered businesses. Invoices and credits notes must be exchanged in a prescribed digital format.

How E-Invoicing works   

Belgium's e-invoicing system runs through the Peppol (Pan-European Public Procurement Online) network, a secure digital framework that allows businesses to exchange invoices and credit notes electronically through certified Access Points.

E-Invoicing will be supported in Zoho Books, Zoho Billing and Zoho Inventory.
