      Accounting Review from Dmitrii Legetskii

      This company helped us set up our accounting system from beginning to end. I am a serial entrepreneur with experience working with many different accounting groups and this one has been the most responsive overall. They have helped us with registering the business, putting together payroll, and getting our quarterly tax returns filed. They have been also very helpful with giving personal tax advice. I would recommend them to any other friends and especially other business owners.

      They were easy to deal with. George Dimov, CPA successfully delivered the project as per the client's requirements. The service provider utilized Email and messaging apps for effective responsiveness and communication. They were also easy to work with. Ultimately, the client was satisfied with the partnership.

      Sherry Wright's Review Sourced from Google

      I am the business manager for a medical practice in Newburgh, IN. I have been a manger for over 30 yrs. Kemper is the best that I have dealt with by far. Their customer service and knowledge out weighs any I have ever experienced. Nathaniel our IT go to guy, is awesome. He always answers his calls no matter what time of day or night and is always on it. He attends to all of our needs from small to huge, he is an all around great guy. John our CPA is just as awesome. Always friendly, very helpfu when you are stressed out, very knowledgable and doesn't make you feel inapt. From the receptionist to all the IT and even the partners, couldn't ask for a better of group of people to work with. Thank you, Kemper!

      Tiffany Bentley's Review Sourced from Google

      I've had a great experience using Pilot in my therapy practice! Admitting I needed extra help with my accounting was a tough step, but the team at Pilot has been incredibly supportive. I really appreciate being able to reach real people when I need help—no long waits with a chatbot only to have to explain things all over again. Everyone I’ve worked with has been helpful, responsive, and down to earth.

      I am a new business owner who just started a new Company. Financials and bookkeeping are not my super-power. After careful consideration I decided to try Pilot for my bookkeeping and taxes needs and I couldnt be more happy.Every staff member I got in touch with has been extremely helpfull, willing to answer all my questions and educate me, and extremel professioal and accurate.I would recommend to everybody who doesn't ahve the time and/or knowledge to stay on top of all financials.
