ATPP saved us money and beat the other guys with their personalized service. We’ve tried the national services and ATPP beats them on every front. Thanks ATPP.
Winstons Bar, Andrew Fiscella, Los Angeles, CA
I have worked with ADP and Paychex over the years, and my experience with ATPP has certainly been the best by far. Your employees have been a pleasure to work with; my questions or situations have always been resolved to the fullest. I feel confident when there are changes in federal, state, or local laws that affect payroll; you are always on top of everything.
Yogurt Stop, Marta Knittel, West Hollywood
Every payroll service we have tried is the same UNLESS there is a problem to deal with. We were having the same issue with multiple providers until ATPP stepped in and solved it once and for all. They actually have a live person to talk to each time you call and the payroll specialist knows my name. They are truly the best!
California Dental Group, Anna Durand, Multiple CA locations
In a nutshell, ATPP is our partner in payroll. The staff is professional, courteous and friendly and always there for you no matter the question comes up. We have tried the online payroll providers and the big providers and no one beats ATPP in service.
AVN Media Network, Erica Nasser, Chatsworth, CA
We have been using ATPP for over 7 years. We have tried ADP, Paychex and on-line services—ATPP is far superior in service and cost. I highly recommend them to all business owners looking to improve the bottom line and get better service. They are the best! Thanks ATPP!
Good Company, Jack Merrick, Los Angeles, CA
Having ATPP has made my job a lot easier. Your staff has always been willing to go above and beyond to keep us satisfied. Your representatives are professional and friendly and know the payroll business inside and out.

We started using ATPP in 2003. We immediately loved their customer service. I would never speak to a machine like a lot of other payroll companies, we always spoke to a representative. I’ve recommended them to other business owners that I know because they have made payroll for us seamless and stress-free.

As former IRS tax attorneys we wouldn’t trust our own payroll to just anybody. We’ve seen firsthand what payroll issues cause for business owners and so we turn to ATPP to make sure it’s done right for us and our clients.
