Our Firm

Hello friend,

We are a full-service public accounting firm which provides tax (business/personal), bookkeeping, consulting, IRS support, expert witness testimony, financial modeling, financial statement review, and financial coaching services (be your own accountant).

We are not the stereotypical accountants in that... we are not sticks in the mud! We aim to build a personal relationship with our clients with a fun, cordial attitude. Whether you’re worried about a tax issue, starting a business, or a seasoned business owner, we want to be the partner that you can rely on to save you time, money, and STRESS!

M&A does not have an office..... the team works remotely in the South Florida area. We have found that video conferencing and screen sharing with our friends (clients) is just as effective. Plus, offices are expensive, boring, and not needed. We pass the cost savings on to you.

We take our work very seriously and won't sleep until the job is done right and value is added. Please let us know how we can save you time, money, and STRESS.

We look forward to hearing from you.

Vince Mongio, CPA, CIA, CFE, MACC


Mongio & Associates CPAs LLC

Military Veterans and First Responders: As a veteran of the United States Army, it is my responsibility to ensure that my brothers and sisters in arms are taken care of. VERY special attention and consideration will be given to all U.S Military (active and inactive), LEOs, and first responders. Further, 1+% of M&A's profits are reserved for charitable contributions to organizations whose mission it is to support wounded warriors and other noble recipients.

Practice Areas

Tax prep and Strategy

More than just filing. We provide sound guidance and tax planning that can save you 10 times more in tax than what we charge.

  • ​Consolidated tax returns
  • Pass-through entities
  • C corps
  • Personal

You'd be surprised how fair our fees are compared to the "other guys."

Oh, and we don't mail anything to you, especially those awkward 100 page organizers. Everything is e-signed and you will have your own portal to upload your tax documents and answer tax questions.

Financial Statement Preparation & Reviews
We have performed thousands of Financial  Statement reviews for Regulation Crowdfunding and commercial lending. We make the process as painless as possible while ensuring the integrity and professionalism of the financials, notes, and disclosures.

Startup & Advisory
Advice - What do you want to do and what will get in your way?

​We enjoy working with startups more than any other form of business and you will have our genuine attention and commitment as long as you need us. We will advise you on the best practices of firms in your industry and help with strategic decisions such as outsourcing, expansion, restructuring, divesting, new product lines, the works.

Business Valuations & Acquisition Due Diligence
Want to buy a business? Want to know it's value? What is the definition of value? Should I pay for the value of the business's assets or the value of the potential future income?

​These questions can overwhelm many. Fortunately for you, the CPAs at M&A have facilitated the acquisition of businesses from the valuation stage to the due-diligence stage.

​Due-diligence - a fancy word for hiring M&A to gain reasonable assurance that the seller isn't hiding anything. We know what to look at and have proprietary techniques to gain reasonable assurance that the facts and data that you relied on to make a purchase decision of free from material inaccuracies or misstatements. 

Xero, Quickbooks (desktop & online), and excel.

From implementation, to setting up a chart of accounts, to bank reconciliations, to integration with 3rd party software. The financial statements (books) can be some of the most dreadful chores of operating a business. However, the books are the pulse of your business and need to be designed to provide meaningful data in the most automated fashion. We have been there, done that 1000 times. We can provide regular monitoring and maintenance of your financials to ensure that they are updated year-round in order for you to make informed business decisions.   

Forensic Accounting & Expert Witness Services

M&A has experience in performing financial analysis to assist in recovering lost profits and awarding damages. We can provide certified statements of fact regarding accounting standards and transaction treatment. We will also show up in court to defend our work.
