Understanding Payroll:

Payroll is more than just the mechanism through which employees receive their salaries; it’s a critical function that bridges human resources, accounting, and legal compliance within a business. Understanding payroll in a comprehensive way requires an appreciation of its various elements and the implications it has on both the employer and the employee.
