Paychex Payroll Services can save you and your business time so that you can focus on what matters most. Hear from our customers about why they choose Paychex to help ease the payroll burden.

"StratasCorp Technologies was quickly outgrowing their payroll provider. Paychex helped them save 10 hours a month and $10,000 a year in tax penalties".

“What we learned in a discovery process with Paychex was all the different services that were available. That was music to my ears as a new CFO …. From an efficiency standpoint, knowing we could have our 401(k) under your program, having the management and compliance done with one party obviously makes my life a lot easier.”

"As a recruitment tool, the 401(k) is a very integral part of what we offer our employees."

"The daily time that I don’t spend on (payroll) … it really changes my daily routine. It allows me to make phone calls, answer emails, talk with general contractors and talk with my franchise (personnel). Having the ability to do that streamlines both processes."

Plumbing Doctor was spending too much time tracking down information on how new regulations could impact their business and doing research to get answers for their HR questions. Working with Paychex PEO provides them with 80 hours a month to focus on growing their business.
