In just a few weeks, 4B AG, in collaboration with TimeTool, implemented a fully integrated time-tracking system. “We rolled out the system in less than four months,” says Ivo Estermann, HR Project Manager and the main contact for TimeTool. “This was only possible because we worked together as partners.” ## Ivo Estermann: Why TimeTool Stands Out In a video interview (in German), Ivo Estermann shares fascinating insights into the partnership with TimeTool, explaining how the implementation was completed in record time. From fair compensation for installation staff who travel directly from home to construction sites, to the automation of project bookings – TimeTool and 4B AG co-developed solutions that work seamlessly in day-to-day operations. “Many can track time, but TimeTool does so much more,” says Ivo Estermann. Thanks to the close collaboration and innovative spirit of TimeTool, 4B AG has been able to free up resources and optimise its processes sustainably.
