Excel time tracking is a method of tracking the time employees spend on projects, tasks or clients through an Excel spreadsheet. The timesheet report will have columns with parameters like "Start Time", "End Time", "Hourly Rate" "Client activity", "Overtime" etc. for each employee. An Excel time tracking record is useful to access the performance of employees, keep a tab on the time spent on projects, and use the data for HR, billing clients, payroll management, etc.
