Calculating employee hours manually, through any method, has the potential to be fraught with errors. Even the most detail-oriented people are prone to make mistakes. The slightest error or miscalculation can cost your business hundreds or even thousands of dollars. An automated timekeeping process nearly eliminates the possibility of human calculation errors, and with it the time spent trying to fix these errors. Instead of wasting time trying to identify mistakes, your staff can run reports to track employee behavior and find new ways to save your organization revenue.
