With a manual payroll process, an HR or payroll professional has to:
collect all employees’ hours worked and approved time-off requests
enter pay rates, bonuses, commissions and more
calculate overtime and other pay changes by hand
key in new employee data
vet taxes, benefits and other deductions
Payroll automation, on the other hand, automatically completes these tasks, allowing HR and payroll pros to manage payroll as a whole rather than entering and executing it themselves.
