View Fact Sheet
The Beginning

Many payroll processors were ignoring a huge potential market - the 98 percent of American businesses with fewer than 100 employees. In 1971, B. Thomas Golisano took advantage of this opportunity, and with $3,000, one employee, and 40 clients, he founded a new company in Rochester, NY called Paymaster - soon to be Paychex, to provide payroll to small- to-medium sized businesses.

Company Consolidation

Paychex quickly expanded beyond Rochester to include 18 franchises and partnerships, which in 1979 were consolidated into one privately-held company.
