"I highly recommend Maryann O'Connor for any QuickBooks work you may need. Maryann helped me think through start-up costs and future projections for my new business. She is very experienced at what she does — but also is calm, accommodating, and flexible in her approach. I believe these are important traits to have when working with those who think they have a good idea — but don't have any numbers to back it up!"

"Maryann O'Connor assisted me in the administration and bookkeeping of my business during a period where I was focused on doing what I was good at and neglecting the administration of my business. When Maryann arrived she had months of invoicing and bookkeeping to catch up on and she did it in an efficient and speedy manner.  Quickly she brought my business to the point that it was operating in a manner it should and then was able to implement a daily, weekly, monthly system so that I could meet my business goals. What makes Maryann unique is she is professional, flexible, resilient, up beat, efficient, and effective in and out of stressful situations.  She is an objective visionary thinker and I found her expertise in understanding small business assisted me in articulating where I wanted to take my business next and how to do it. Without Maryann, I know that my business would not be where it is today.  Maryann assisted me from growing my income from 20,000 to 100,00 in a very short time.  I am forever grateful to Maryann's spirt, friendship, and willingness to help me create a business that does so well."

“My accountant recommended Maryann to help me with some of the problems I was having with QuickBooks.  Since I do not have an accounting background, I was happy for any help I could get.  Maryann was extremely helpful.  She took my file, reorganized my chart of accounts, cleaned up my checking account, and now all I have to do is follow the way she set things up.  Very easy!  Thanks Maryann!”
