What is the difference between managing payroll in-house and payroll outsourcing services?

When businesses manage payroll in-house, they rely on internal HR or finance teams to calculate salaries, deductions, and statutory contributions. Payroll outsourcing services, on the other hand, shift these responsibilities to an external provider with specialised expertise and technology. Outsourcing is often more cost-effective for SMEs and growing companies that lack dedicated payroll specialists.
