We all do the best with our core competencies. Everything else should be done by others. This includes the cleaning staff, for example. In this case people outside of the business – and business hours – come in like elves, and clean everything just as we would like. It is important to know who is allowed to enter and how long they have worked. After all, you don’t see elves. JERRA hilft helps, because whoever logs on and off with biometric data is also visible to us and your billing center. Even during normal working hours, there are always third-party companies that come in and carry out work for you. Think of the heating technician who performs a service at regular intervals, or the air-conditioning that needs annual inspections, or the craftsman who carries out repairs. They are all cases for JERRA COMPLETE SOLUTIONS, that also save you money. Because with biometric control, you know whether it was the expensive master who was present, or the apprentice who did the job. The hourly rate times the number of hours can already be quite a sum. With mobile JERRA T-TABLETS and JERRA SOFTWARE you can even store the number of working hours of the craftsmen, so that your maintenance costs don’t explode.
