I worked for a company for almost 2 years that used ADP for their payroll services and with ADP's inconsistencies and errors, I am having to deal with the problems of the financial inconsistencies because they did not take out enough state taxes of my paycheck and every second and third check I received they did not even take out state taxes at all. I would not recommend this company because they messed up everything and I will not ever refer them to anybody I know. Nobody should have to go through emotionally, physically, and financially what I am having to go through because of this companies inconsistencies and un-professionalism.
