Whether you are a current or prospective client, rest assured that individuals and businesses who choose Thomas S. Bates, CPA, PC receive competent and timely advice.

I am sensitive to high CPA fees and develop creative and innovative ways to help clients control fees. This begins with continuity of service. I am the one who provides the important accounting, auditing and tax services directly to my clients. You will not have to “train” a new staff personal assigned to your engagement each year. By working directly with the owner of the CPA firm, the “middleman” is eliminated. This reduces inefficiencies in the engagement, maintains the highest level of competency on an engagement and saves unnecessary staff fees.

When planning an engagement, the consideration of the fee is critical. I provide my clients with a written fee estimate and opportunities for controlling fees before the engagement begins. After all, you are the client and you should know how much a service will cost before agreeing to it.

I listen to my clients and assist them in meeting their needs at the lowest cost. I don’t “impose” unnecessary services on my clients. Instead I can design customized accounting and auditing services that meet a client’s needs without extra, unnecessary services. For example, I assisted an entity with 50 branch locations throughout New Hampshire to develop a customized audit program and report that provided the CFO of the parent organization with essential information about key financial elements. This was more meaningful than the “traditional” full financial statement audit that was too costly and ineffective.
