internetvista has implemented an Information Security Management System aligned with ISO/IEC 27001:2022 as part of its foundational security and governance approach. The objective of this ISMS is to protect information assets across the company’s activities, including product development, infrastructure, operations, support and commercial processes.

At the start of 2026, structured electronic invoicing is no longer an upcoming regulatory change in Belgium. It is now the standard operating framework for domestic B2B transactions between VAT-registered companies. The legal mandate is in place. The ecosystem is active. The real question has shifted from “when will this happen?” to “how well is the market actually coping with it?”

Across Europe, companies are re-examining their infrastructure choices and asking a more fundamental question: who really controls our data? The result is a growing interest in on-premise deployments, local hosting, and hybrid architectures that restore visibility and sovereignty. This shift is not ideological. It is practical.

Peppol is becoming the backbone of the 2026 Belgian B2B e-invoicing mandate, and companies of all sizes are preparing to adapt their billing workflows. Yet despite the growing amount of documentation available, many businesses still struggle with practical questions: What happens if I resend the same invoice? Can I invoice foreign clients? Can I correct a document once it’s been sent? Why does Peppol validate some invoices but not others?

Our consultants work hands-on with your teams to ensure a perfect fit, from mapping and integrations to architectural alignment, audit readiness and hardened environments for ISO 27001 and internal governance requirements.
