My name is Arend-Jan Kauffmann and I am a freelance and independent Microsoft Dynamics 365 Business Central consultant and trainer. With over 20 years of experience with Microsoft Dynamics NAV / Business Central and 30+ years of experience in the IT industry, I have a solid track record in this business.

With a strong focus on architecture, design and integration, I have worked in different roles and with a broad range of technologies and platforms, including C/SIDE & VS Code development, C/AL and AL, Microsoft .Net, Microsoft Azure and Office 365. I strongly believe that knowledge increases by sharing it, not by saving it. By delivering workshops and being a frequent speaker at conferences, I can put this into practice. And of course by maintaining this blog.

Besides this, I have co-founded the Dutch Dynamics Community, a community for all Dutch Dynamics professionals to share knowledge. Since 2013 I am awarded as Microsoft MVP Business Solutions.


As an independent freelancer, I can help your company with a broad range of services around Business Central:

  • Workshops about AL development
  • Coaching of a development team
  • Developing of Business Central extensions
  • Integrating with the outside world, like PowerApps, Flow, API’s, etc.
  • Analysis and advice on how to move bespoke customizations into extensions

If you are interested in any of these services or need help with something else, please contact me.
