Inventories are a burdensome duty that are required by law. Nevertheless, an inventory must be carried out and it creates a valid data basis about the stocks. It makes little sense to only check whether the book inventory is also available, but to count with open eyes what is available. High inventory costs are incurred due to the downtime of productive business operations and the many hours spent on rework. For example, paper-based inventory lists must be evaluated, entered into the ERP system, and then the difference list must still be printed out and cross-checked again. Instead, a digital inventory solution from COSYS provides the ability to quickly and easily count area by count area using loaner equipment. The results also produce a difference list that can then be recounted by a secondary counter. This results in fewer interruptions to business operations and reduced rework time.
