I've worked with Isoldi Bookkeeping Services since 2017, and I now can't imagine how I would run my business without them. They handle everything from invoicing to payroll, and my books are always in perfect order. In addition to being great bookkeepers, they're incredibly responsive to requests and great communicators. As a business owner, I know first hand that it can be nerve-wracking trying to decide who to hire to help you with the books - I'm here to tell you that you've found the best ones. Stop searching and call Isoldi Bookkeeping - you'll be in good hands from the moment they pick up the phone.

I cannot recommend a book keeping firm more highly than Isoldi. The owner Michelle Isoldi is truly an asset to your company. There are very few professionals with her level of expertise and professionalism. She is always one step ahead of accounts receivable and following the particular protocols . She provides recommendations for professional services such as , insurance , accountants in additional to multiple resources for great efficiency . She literally supports every facet of your business. Simply the best book keeping firm you will ever find on the east coast. I know, as i have worked with many others and none match the high quality and ethics of Michelle Isoldi.

We have been working with Isoldi Bookkeeping for almost 1 year now and are very happy. They are a cost effective alternative to hiring an inside Bookkeeper, time efficient and very knowledgeable on good accounting practice and Quickbooks. Michelle is also a pleasure to work with. We highly recommend.

Isoldi Bookkeeping takes care of all our company's bookkeeping needs. They have been instrumental in helping us move from a desktop QuickBooks system, to QuickBooks on line. This allows me the ability to handle small entries and run reports from my remote location. They have taken the time to understand our business needs and taken the burden off our staff to handle the accounting side of the business. Their staff is exceptionally hard-working, knowledgeable, fast (!) and very pleasant to work with. If your business is looking for Bookkeeping services - look no further - you have found them!
