Dirk Willekens, Billit (e-invoice Program Manager)
At Billit, we are generally skeptical of hybrid invoice formats. However, since different standards are in place in France and Germany, we adapt accordingly.
valitool® enables us to quickly and reliably validate even large invoices containing a combination of PDF and XML data. From my work on the CEN and Peppol committees, I am familiar with the complexity of these validation processes—and valitool® meets these requirements with ease.

Valitool, for companies that take e-invoicing seriously
Anyone who views e-billing not as a mere checkbox item but as an integral part of digital business processes cannot ignore valitool. Right from the start, I saw firsthand that it was developed based on real-world experience.
State-of-the-art in its field – technically sophisticated
Valitool stands out for its depth of content, which is rarely found in this market. Especially in times of increasing regulatory complexity—think ViDA, reporting systems, and a variety of formats—it’s essential to use a tool that not only maps this complexity but also explains it clearly, integrates seamlessly into business processes from a technical standpoint, and is easy to use from the user’s perspective.
What really stands out: The product is clearly backed by expertise. No marketing clichés, no buzzwords—just clear explanations, technical precision, and an understanding of what really matters to companies in their day-to-day operations—whether it’s format validation, country-specific requirements, or integration into existing processes.
Timeliness That Doesn’t Lag Behind
One of the biggest problems with many e-invoicing solutions is the delay between new regulatory requirements and their implementation in the product. Valitool takes this issue seriously. In practice, you’ll see that they don’t just respond to immediate requests, but work with foresight—proactively, not reactively.
My Conclusion
For companies that view e-invoicing not as a burdensome obligation but as an integral part of their financial and tax processes, Valitool offers a highly professional, practical solution. As a consultant with more than 30 years of experience, I can wholeheartedly recommend this solution: it was developed not just for the market, but based on the market itself.
