Introduction: We use a team approach to provide a high level of service to our clients. We are not the cheapest but we believe our clients receive a return on their investment (ROI). We assist our clients in achieving their goals. We enjoy teaching our clients areas they do not understand. Many business owners and individuals are good at what they do but do not truly understand tax and accounting. We empower our clients to self manage their business.

Jen H.

Mark Mirsky and the team at ROI Business Services have helped turn my business finances around. After a negative experience with a previous accountant, Mark was able to show me what had been done wrong, and help me understand the changes that needed to be made in order to right the wrongs. He takes the time to educate his clients, which I really value. His knowledge regarding business tax and accounting is far more than I will ever comprehend, and I will continue working with him for both my business and personal taxes and accounting.

  • What should the customer know about your pricing (e.g., discounts, fees)?

    Each situation is different so we don't have a standard.

  • What is your typical process for working with a new customer?

    We listen to what their needs are and document their goals. Then we assist in creating a plan to achieve those goals.

  • What education and/or training do you have that relates to your work?

    Two of our partners teach for the AICPA - partnerships, S corps, C Corps, advanced individuals, estate, gift, and trust taxation, and accounting periods and methods. We are CPAs and EAs so we are all licensed professionals.
