For my contracting company, I was looking for a 'no-nonsense' program where my employees could track their hours, and a central place for communication and storing files. Without too much fuss involved. Koen convinced me to try Werkbriefje with his clear demo, and after a week of trying it, I was sold. Super program, well-organized, and quick to understand. The staff were also used to it after just the first week. I also received quick help with questions or problems; a quick message to Koen and the issue was solved immediately. In short, a fantastic program for the entrepreneur in the construction industry!
