„We use the PrefSuite to produce our wood- and vinyl windows and doors. Since converting to PrefSuite we also use the PrefOrganizer for our capacity - and shipping planning. Thanks to the organizer, we have not only achieved an ecological improvement - because we now produce without paper - but also our production processes have been optimized. Today, our customers are increasingly praising our delivery reliability and, thanks to efficient planning, we can guarantee that the ordered goods will be delivered at the specified time. Of course, this also leads to increased efficiency in our logistics, since a multiple approach to the dealer can be avoided 100%. We also appreciate the co-operation with Prefco and is characterized by a partnership understanding“
