Running payroll manually is a liability. Tax codes change constantly, filing deadlines vary by state, and a single miscalculation can trigger IRS penalties. Modern payroll software automates tax calculations, files returns on your behalf, handles direct deposits, and manages benefits enrollment. We evaluated five platforms on the features that matter most to small businesses: accuracy, tax filing, benefits administration, HR tools, and total cost of ownership.
