FAQ: Frequently Asked Questions About Payroll Outsourcing Services 

What Is Payroll Outsourcing?

Payroll Outsourcing is the practice of hiring an external service provider to manage payroll tasks within an agreed scope, such as payroll calculation, earnings, deductions, tax, Social Security, payslips, and reports. The organization still needs to provide data and review the results before closing payroll.

 

Does HR Still Need to Review Payroll When Using Payroll Outsourcing?

Yes. The provider calculates payroll based on the data and conditions supplied by the organization. HR or an authorized person should therefore review completeness, unusual items, and payroll totals before approving payment for every payroll cycle.

 

How Is Payroll Outsourcing Different from Payroll Software?

Payroll software is a tool that HR teams use to calculate and review payroll themselves, while Payroll Outsourcing involves external specialists handling the process within an agreed scope. Some providers also include an HR system for use alongside the outsourcing service.
