The story of Abacus Payroll, Inc.

Abacus Payroll, Inc. was established in 1999 with one purpose: To simplify the lives of Alloy Silverstein’s small business clients.

At the time, the payroll industry was becoming more and more complex and regulated. Similarly, having a middle-man between the third-party payroll processer and the business’s CPA was an extra step that further complicated payroll and tax filing tasks.

By launching Abacus Payroll, Inc., we could guarantee to our clients that there would be no more complaints about inadequate and unresponsive service. Certain processes could be more streamlined, such as end-of-year bonuses and tax planning.

In 2008, Cherry Hill, NJ based Abacus Payroll and Alloy Silverstein Accountants and Advisors expanded with the opening of a Hammonton, NJ office. Abacus experienced further growth in 2019 with a merger with Payroll Express, Inc., based out of Northfield, NJ.


Our number one goal has always been to serve and take care of the client. No matter what division of the Alloy Silverstein Group you’re working with, you know to expect superior client service and responsiveness. As of 2022, Abacus boasted an impressive 99.3% client retention rate. Very rarely do we see turnover because our clients are so happy with the one-on-one service they get with the Abacus Payroll team. Especially if someone has come from a national provider, they can see the stark difference in the client service experience.

Twenty-five years in, Abacus Payroll, Inc. may call Hammonton, NJ home, but proudly has clients throughout the United States and has remained true to the founding promise of client service excellence.

What our team has to say:

“Abacus was created with the idea of simplifying our clients’ lives for the better. Payroll shouldn’t be another headache and hassle. We have many longtime clients and a good core staff who have been with us over the years, so you’re not seeing that constant representative turnover or dialing a 1-800 number. You’re picking up the phone to speak with someone who knows your business.”

Ren Cicalese

“We listen to our clients about what they want/need to give them the best possible solutions for their business. The main thing is our customer service.  When clients call or email us – we answer!  The biggest complaint we hear from clients when they make the switch to Abacus is the horrible customer service they received from their previous provider.  “

Anne Marie Galfo

“Abacus stands out from other competitors by providing a personal attention to all its’ clients. Our clients also appreciate our attention to detail with each payroll. They know that any problem that arises will be solved right away. We are a real hands-on payroll company. I enjoy the vast variety of clientele and the challenges each one of the payrolls bring with it.

Jim Storey

“I started in Abacus in 2003 so I’ve seen the company evolve from only about 100 clients to where we are today, which really has been something to see. I love how we expanded into different types of businesses over the years, for example our Cannabis clientele. We also offer many services just like our larger competitors, so clients get the best of both worlds.”
