Payroll · Head to head
Gusto vs OnPay
Both products compete in Payroll. Payroll software calculates and processes employee pay — applying tax withholding, garnishments, deductions, and direct deposit — and manages the ongoing compliance obligations that come with it: quarterly filings, year-end W-2 and 1099 generation, new hire reporting, and multi-jurisdiction tax remittance. Employers use it to pay employees accurately and on time while transferring regulatory compliance liability to a vendor. Here are the facts the B4 Index maintains on each, side by side.
