“I’ve been in accounting for over 30 years. Making sure business owners remain in compliance with current laws is a standard practice for most firms, including HAS. But what sets us apart is that we take an active interest in each of our clients, inspiring a trust that everyone seeks in their accountant.

We don’t just focus on one part of your business, such as bookkeeping or tax. We look at how ALL of your processes work together to contribute to the success and profitability of your business.

Our clients are our partners and our friends.”

{"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!

{Kathy and her team do an excellent job. They have provided great service to my clients and cleared up complex financial issues for them. They are timely, professional, responsive, and willing to assist entrepreneurs in understanding their financial statements. They stay on the cutting edge and provide proven, practical advice. They are very easy to approach and understand the challenges many business owners face.

Rhoda Kreuzer, President
{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.
