Paychex
full-service-payroll · USPaychex is the second-largest payroll provider in the US and is particularly known for its dedicated payroll specialist model — each client is assigned a named payroll specialist who handles questions and issues, providing a human touch that purely self-serve platforms lack. The company serves over 740,000 businesses from sole proprietors to mid-market companies and has been processing payroll since 1971. Paychex Flex is its modern platform covering payroll, time and attendance, benefits administration, HR administration, and recruiting. Unlike ADP which leads on enterprise accounts, Paychex's sweet spot is small to medium businesses that want full-service payroll with dedicated support. Its HR Support Center provides businesses with access to HR professionals for compliance guidance. Paychex also offers business insurance including workers compensation and retirement plan administration. Verify current pricing at paychex.com.
