Mandatory B2B E-Invoicing in Belgium from 1 January 2026

Electronic invoicing will soon become the norm, and Belgium has taken the next step with a concrete date. John Schouten, Director Product Management at ISPnext, explains, ‘From 1 January 2026, B2B E-Invoicing will become mandatory in Belgium. This underlines that it is only a matter of time before electronic invoicing becomes a standard across the European Union.’ We are closely monitoring these developments and continue to proactively inform our network so that organisations are prepared in time for this important transition.
