“Hire Her! You will be pleased! Stacy is a dream come true, honestly. I hired another bookkeeper prior to Stacy, who was much more expensive and had a quirky bookkeeping style. We parted ways. Stacy is the Bookkeeper extrodinaire! Really. She loaded on some QB software that makes sharing docs a breeze. She picks up and delivers everything. We have had a couple of meetings in which she sized up the job and got to work. (I was having long, monthly meetings with the previous bookkeeper). Everything gets done efficiently and in a timely manner. I am not involved! As an added bonus, she has experience in insurance billing, and has been able to take on the bookkeeping piece of it. None of the other bookkeepers I spoke to were willing to touch it. It is such peace of mind for me to have this job off my desk and handled expertly, so I can turn my attention to my work.”

“Accommodating, and offers great advice.
Scheduling appointments with Stacy is flexible and easy. She helped me set up Quickbooks for my small business when I was keeping my books on spreadsheets. I was overwhelmed by doing things the hard way and Stacy simplified my life with a couple of appointments and a quick/easy Quickbooks setup.”
Float Harder

“An Excellent Choice. Stacy manages the books for the Maine Academy of Gymnastics in Westbrook. We found Stacy through an employment agency around a decade ago. When she took a look at our accounts, she was able to adjust and manage them in a far better, more understandable way than we’d experienced before, at a far better price. She also referred us to our financial advisor and tax planner which has been another blessing for us. We have been very fortunate to have Stacy Ayotte and couldn’t be more pleased with her excellent, as well as timely work. Stacy has made managing our books, and preparing for our year end taxes far less complicated and stressful. I recommend her highly and am forever thankful to have found her. Stacy Ayotte and the Back Office Experts are excellent.”

“I want to do as much of my accounting as I can, but I can’t do it alone. Stacy is there when I need her. She teaches me what I need to know, corrects my mistakes, and makes sure that I get the right forms in. She saved me almost $400 dollars recently when I got a letter from the IRS saying that I owed money. She is very personable, is on time, creative, smart. She loves accounting. She is exactly who I had been looking for. “
