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

“(With staff in multiple states), we had different state labor laws (to deal with) … we didn’t have the resources to address …. Paychex sorted through that for us so we didn’t have to spend any time or effort on figuring it out.”

"Julie [my Paychex HR consultant] does a good job of bringing the best out of us."

“Payroll, HR, keeping up with the changing IRS rules; these are things that are critical to making our business hum … Not having to invest in the back office means we can put our resources into our core business.”

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