E-invoicing becomes a reality: how to prepare starting today?

The digitalization of accounting is entering a new phase: as of January 1st, 2026, e-invoicing will become mandatory in Belgium for many companies and self-employed individuals. In Luxembourg, this obligation is expected to come into effect by 2028.

But more than just a constraint, this transition represents an opportunity: to modernize processes, gain efficiency, and ensure compliance with new regulatory requirements.

InexDemat, a solution designed to support this change

To meet these new obligations, tailored tools are emerging. Among them is InexDemat, a certified digital platform that facilitates the issuance, reception, and management of electronic invoices, in compliance with the European Peppol standard.

It is aimed at organizations wishing to:

• Access a simple and intuitive dashboard to manage their business
• Receive electronic invoices
• Benefit from a secure archiving system for their documents
• Create and send electronic invoices using the integrated invoicing module
• Manage the payment of their supplier invoices

Human support at the heart of the transition

Switching to e-invoicing is not just about adopting a new tool. It also requires a clear understanding of the stakes, a gradual implementation process, and a tailored onboarding approach for each organization.

This is why personalized support is offered throughout the process: advice, demonstrations, training sessions, and provided to guide each company and self-employed individual, whether they are already a client or in the discovery phase.
