Mergers & Acquisitions Advisory

Buying, selling, or preparing for either. We make the numbers tell the right story.

M&A deals come down to financials a buyer can trust and a seller can defend. Whether you’re getting ready to sell, evaluating an acquisition, or somewhere in the middle of due diligence, our team handles the financial side so you can focus on the deal itself.

Business discussion between men and a woman
The reality of M&A transactions

Most deals fall apart in due diligence, not at the negotiating table.

Buyers walk when reported earnings don’t match actual cash flow. Sellers leave money on the table when their financials aren’t presentation-ready.

Tax structure decisions made in the final week often cost six or seven figures that proper planning would have saved.

The work that happens before a buyer sees a number is what protects the deal. That’s where we come in.

What we help with

Every stage of the transaction, covered.

Whether you’re preparing financials for a sale that’s a year out, evaluating a target right now, or sitting in a data room next week, we step in at whatever stage you’re at.

01
Preparation

Transaction-Ready Financials

Before a deal ever starts, your financials need to look the part. We take messy or seller-style books and turn them into CPA-prepared statements that align with how a buyer wants to see them: accrual-based, normalized, properly categorized. Less friction in due diligence means a faster close and a stronger valuation.

02
Due-dilligence

Quality of Earnings (QofE Lite & Proof of Cash)

A QofE report validates that the earnings a seller is reporting are real, sustainable, and tied to actual cash flow. Our QofE Lite is a streamlined version built for lower-middle-market deals where a full Big 4-style QofE is overkill but skipping diligence is risky. Pair it with a Proof of Cash analysis and you have what most SBA lenders and buyers actually want.

03
Tax strategy

Deal Structuring & Tax Optimization

Asset sale or stock sale. Installment treatment. F-reorganization. Working capital pegs. The structure of a deal often matters more to your after-tax outcome than the headline price. We work alongside your attorney and broker to model the tax impact of each path and structure the transaction to keep more of the proceeds in your hands.

04
Buyer-side support

Acquisition & SBA Financing Readiness

If you’re the one buying, the financial work is just as critical. We help acquirers evaluate target financials, confirm what they’re really purchasing, and prepare the documentation SBA lenders need to approve financing. For first-time buyers especially, having a CPA in your corner is the difference between buying a business and inheriting a problem.

Why it works

CPAs who actually understand deal mechanics.

Most accountants prepare tax returns. M&A advisory is a different discipline – it requires understanding how buyers think, how lenders underwrite, and how transactions actually close. Our team works on these deals year-round, not as a side project.

You won't get blindsided in due diligence

Issues that surface late kill deals. We surface them early so they can be addressed, not weaponized.

Your tax outcome will match the deal value

A great sale price means nothing if half of it goes to taxes that smart structuring would have avoided.

With Thompson Flaherty M&A Advisory:

From fellow business owners

"I honestly can’t say enough good things about Thompson Flaherty. They’ve saved me a significant amount of money just by taking the extra time to explain tax law changes and applying things I didn’t even know about. I also really appreciate how responsive they are. I know how busy CPA firms get during tax season, but they’ve always gotten back to me—whether it’s a call or email—which goes a long way."
