Our Company

HAS is a woman-owned firm and takes pride in its staff that is highly trained and experienced in a variety of fields. But what really sets us apart is the active interest we take in each of our clients. We’re more than just an accounting firm. We’re your friends and your partners. We go beyond the numbers and develop real, lasting relationships with our clients. We work to understand their needs and come up with solutions that best fit their business.

Our goal is to make our client’s lives easier and give them peace of mind so that they can focus on running their businesses.

Giving Back to the Community

As a fellow small business of over 30 years, there are many lessons we had to learn the hard way. Looking back, we now understand the value of using the expertise and knowledge of the resources available to us. Besides saving us many headaches, these resources could have helped us avoid lost revenue and grow our business much faster.

That is why we are so passionate about giving back to the community through our new Building Small Business Success series. This community event is a platform that allows us to use our knowledge and skills to give back and help other business owners. This new series will be offered periodically during the year.

New and existing business owners will have the opportunity to meet with one of our accounting professionals about various business issues they face. This is a completely free service offered to community business owners with no commitment or obligations. Be sure to connect with us through social media to stay informed about our upcoming events.

{"We began working with Heintzelman Accounting almost four years ago when they were brought on to help us with monthly bookkeeping. Since then, they have become a true partner and the accounting arm to my firm. They assist us with QuickBooks (QBO) training and support, monthly ledger, asset management and financial statement preparation, payroll, including tax filings for 3 states, end of year tax preparation, as well as cash flow projects and forecasting. What makes them truly unique and exceptional is their ability to work under our deadlines, getting us what we need, when we need it."

{Heintzelman Accounting Services has been involved with DeWitt Packaging since its inception more than 20 years ago. Their experience, expertise and knowledge have been invaluable to us. Even though they have been an independent accounting firm throughout our relationship, we consider them outstanding members of the DeWitt Packaging team.

{Community Bankers of Michigan has retained the services of Heintzelman Accounting for more than 20 years. With a small staff, we rely heavily on the team at Heintzelman Accounting. They understand our business and are responsive and innovative in terms of the services that they offer.  Gives us great peace of mind knowing that we can count on their knowledge and expertise and that they’ve got our backs when challenges arise.  Over the years, we have confidently turned over several functions to Heintzelman Accounting to free up our staff from daily work that is much more sensible to outsource. Their friendly and cost-effective service is helping our association grow, expand and prioritize our energies and resources in different ways. I highly recommend this firm and enjoy working with them!

{During 2014 our quickly growing West Michigan specialty food manufacturing company needed to transition from our out-of-state CPA firm to a local accounting firm. Heintzelman Accounting came highly recommended and their dedicated team did not disappoint. HAS handles all of our bookkeeping, accounting, payroll, and tax needs leaving us time to focus on our passion - creating new, innovative flavors. We were excited to find a firm that provides the flexibility and variety of services that we needed and always meets timelines in thorough detail. The staff of HAS is friendly and has a positive attitude which creates a pleasant accounting firm to work with. It is a testament to the great work culture at Heintzelman Accounting Services.
