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


Sometimes lenders and regulatory agencies require reviewed financial statements. We will verify that your financials are presented in accordance with the relevant framework. We can also prepare them to save you the headache.

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.
