About Taxxor

Find out more about our company

Taxxor is a company founded by Bas Groenveld, Johan Thijs, Rutger Scheepens and Chris Groenveld with the goal to optimise the (financial) reporting process for medium and large companies using intelligent solutions and high quality consultancy. The name Taxxor stands for Taxonomy XBRL Online Reporting.

"Financial reporting should be based on structured data only"

Bas Groenveld - Founder & Director

How we started

Taxxor was founded end of 2017 by four professionals who where all working on different aspects of the financial reporting process for different clients.

Before founding Taxxor we worked together on a non-profit basis to develop proof-of-concepts that would solve typical issues that we all experienced while working on external reporting projects. We felt that XBRL was seen by our clients as a burden and another additional requirement, while we were convinced that the power of structured data could improve the efficiency and accuracy of the reporting process. Our first prototype was created in 2012 and we have been constantly developing towards a solid, secure, structured data based application ever since.

With the XBRL obligation for SEC filings now here, and the obligation for ESMA on it's way, we noticed that there is a large gap to fill in this new market.

At Taxxor, we believe that the whole financial reporting process for companies should be as efficient as possible, while maintaining maximum flexibility in layout for multiple output channels. Creating all necessary filing documents from one system with a minimal effort. All data should be easy to find and reusable.
