Payroll and human resources (HR) are two important business departments with distinct functions and responsibilities in an organisation. While payroll deals with the financial compensation of the employees and the processes by which they get paid, human resources deals with employee relations. However, certain areas of business such as recruitment, salary increases, bonus payments, benefit deductions, leave and termination often require the attention of both payroll and HR.
In many situations the two departments must coordinate together in order to remain efficient. In fact, the overlapping payroll and HR functions and responsibilities are often carried out by the same person in small businesses. Distinguishing the differences between payroll and HR are important for business owners to understand how the two may work together in harmony.
In this article we will cover the functions, responsibilities and importance of payroll and HR, and how the two departments work together.
What is the function of payroll in business?
The main function of payroll is to calculate and distribute wages, salaries, bonuses and commissions to employees of a company accurately, on time, and in compliance with domestic laws. This function is called payroll processing which may be done manually or through industry payroll software such as Simply Payroll. The function of the payroll department is closely tied with accounting because it deals with all the financial documents of employees. Let’s look at the responsibilities of payroll in more detail.
