You will be billed on the number of active employees in your PayBooks payroll account on last day of each month. All employees, except the employees whose exit formalities have been completed (full & final settlement has been done) and whose salary will no longer be calculated using the software, are considered as active.  Employees whose salaries have been put on hold or have been marked for exit (but not completed) will be considered as active employees. And employees who are excluded from payroll will be considered as active employees.
