Klaes Workflow - Example: PVC window production with klaes ERP software for windows and doors

Do you know the problem of work intensification? It is about the fact that we have less and less time for our daily work. Saving time will therefore become a very important success factor for companies in the future. The greatest potential here often lies in the optimisation of internal work processes.

The concept of Klaes solutions is based precisely on this basic idea, because the complete networking of Klaes solutions creates a continuous workflow which perfects all work processes in a company from offer to invoice. With Klaes, you simply have more time for your work.
