What is payroll software and how does it differ from a payroll service?
Payroll software is technology that automates payroll calculation, tax filing, pay stub generation, and year-end reporting. It can be standalone (QuickBooks Payroll, OnPay), part of an HRIS suite (Workday, UKG), or bundled with a full-service payroll provider (ADP, Paychex, Gusto). The term overlaps with payroll services; the distinction is that software implies the employer runs the processing, while service implies the provider runs it.
