According to a 2024 study, buddy punching, one of the most common forms of time theft, affects 75% of US businesses. For a company with 50 employees averaging $50,000 salaries, that translates to approximately $125,000 in annual losses. Even more alarming, research indicates that time theft costs U.S. employers over $400 billion per year.
As a business owner or HR professional, you know that accurate time tracking isn't just about calculating paychecks—it's about protecting your bottom line, ensuring compliance, and building a culture of accountability.
At Lift HCM, we've guided hundreds of companies through the complex decision of selecting the right timekeeping solution. From biometric time clocks to mobile, cloud-based systems, we provide modern time and attendance tracking tools tailored to fit businesses of every size and industry.
