Our regular Customer Day is an event for sharing information and ideas with our customers. It will take place for the 11th time this year: on
4 November 2026, combining a live event at the Wetzlar Stadthalle with a digital stream.
As in previous years, the event will be hosted by mbi employees and customers who use WINPACCS within their organisations.
You will receive information on current and planned WINPACCS innovations, and have the opportunity to ask questions and make requests. You can also network with other WINPACCS users.
Once again, this year's event will be a mixture of exciting presentations, practical workshops and inspiring discussions!
The presentations will be held in English. To help you follow the content, we offer a live translation feature via app or browser. Through this, you can select the language in which you would like to read along on your device. Available languages are German, English, Spanish, and French.

Located in the heart of the state Hessen in central Germany, Wetzlar straddles the river Lahn a mere 30 miles north of Frankfurt. Having been an economic and cultural hub of the region since medieval times, it is now most famous for its optics industry and its association with German national poet Johann Wolfgang von Goethe. With a population of just over 50,000 people, Wetzlar remains a favourite among visitors attracted not just by its historic old town and cathedral, but also its beautiful surroundings along the Lahn valley.
