Customer experiences

Jeroen Aalbers

“Cleaners used to have the reputation of starting late and leaving early. Handwritten timesheets did not always match reality,” Aalbers explains. “With a time clock system, you prevent those discussions and always have real-time insight.”

"We have been working with CleanJack since 2017 and can no longer do without it. Real-time insight is indispensable for us: via the dashboard we can immediately see who is where. It provides peace of mind, overview and prevents discussions about presence. CleanJack is our virtual assistant and makes our work more professional and efficient. Definitely recommended for companies that still work with paper."
