Before any sophisticated buyer in the lower middle market writes a check, they want to know one thing with confidence: is the EBITDA real? That is the fundamental question a Quality of Earnings (QofE) report is designed to answer. It is one of the most important tools in the M&A due diligence toolkit — and one that first-time buyers frequently underestimate or skip entirely, to their eventual regret. A QofE report is not an audit. It is a focused, analytical investigation by an independent accounting firm that examines the sustainability and quality of the business's reported earnings, normalizes out the noise, and gives the buyer a defensible view of the true economic performance of the business they are considering acquiring.
According to transaction advisory professionals and research from accounting firms specializing in M&A due diligence, the QofE process uncovers material findings — issues that affect deal price or structure — in a significant percentage of lower middle market transactions. The investment of $15,000–$40,000 for a professionally conducted QofE review is one of the highest-ROI expenditures in the entire acquisition process, given the risk it manages and the negotiating leverage it provides.
What a Quality of Earnings Report Actually Analyzes
The QofE report goes well beyond confirming the numbers on a seller's P&L. It examines the composition, consistency, and sustainability of every major revenue and expense line in the business. The goal is to arrive at a Normalized EBITDA figure — the earnings that an independent buyer can reasonably expect to generate after removing all owner-specific, non-recurring, and non-operating items.
Revenue Quality Analysis
Revenue quality analysis examines whether reported top-line revenue is genuine, recurring, and representative of future performance. Key questions include: Is revenue recognized consistently and in accordance with accounting standards? Are any large one-time or project-based revenues being presented as recurring? Are any significant customers under contract, or is the revenue highly discretionary? Has revenue been accelerated or deferred in ways that distort the normalized picture? Are there any related-party transactions included in revenue that would not survive the seller's departure?
EBITDA Normalization
Normalization is the process of adjusting reported EBITDA to remove items that are not expected to recur or that reflect the owner's specific situation rather than the business's underlying profitability. Common add-backs — items that increase reported EBITDA to reflect normalized earnings — include owner compensation above market replacement cost, personal expenses run through the business, one-time costs such as litigation settlement or equipment write-offs, and non-cash charges. Common adjustments that reduce EBITDA — items that decrease reported earnings to reflect ongoing costs the buyer will face — include below-market rent paid to a related party, unreported officer compensation, deferred maintenance costs, and below-market management salaries.
- ✅ Legitimate add-backs: Excess owner compensation, one-time professional fees, non-recurring litigation costs, personal vehicle/travel expenses
- ⚠️ Questionable add-backs: "Discretionary" expenses that are actually ongoing, underreported owner compensation replaced by below-market management costs, or recurring items labeled non-recurring
- ❌ Common adjustments that reduce EBITDA: Below-market rent (related-party lease), missing replacement-cost management layer, deferred capital maintenance
Working Capital Analysis
A proper QofE examines not just earnings but also the working capital dynamics of the business — particularly the working capital peg that will be negotiated as part of the purchase agreement. The working capital peg defines how much working capital the seller is required to deliver at closing as a normal operating component of the business. Sellers who understand this often attempt to minimize their working capital delivery by drawing down receivables, stretching payables, or reducing inventory before closing. The QofE report identifies these behaviors and establishes a defensible normalized working capital baseline that protects the buyer.
What QofE Reports Commonly Uncover
In practice, QofE reviews regularly surface findings that materially affect deal terms. The most common include revenue recognition issues — periods where revenue was accelerated into a prior year to boost the financial profile — customer concentration risk that was underemphasized in the seller's presentation, add-backs that the accounting team cannot substantiate with adequate documentation, below-market related-party expenses that will increase post-closing (particularly rent), and working capital deficits that indicate the business will require a capital injection immediately after closing.
These findings do not always kill deals. But they almost always affect them. A QofE finding of $200,000 in non-sustainable add-backs on a business valued at 5x EBITDA translates to $1M in purchase price reduction — a 25:1 return on the cost of the QofE report itself. This is precisely why experienced buyers treat the QofE as an investment, not an expense.
Who Conducts the Quality of Earnings Review?
QofE reports are conducted by CPA firms with M&A transaction advisory practices — not by the company's own accountants, and not by the buyer's own internal finance team. Independence is essential. The reviewing firm must have no existing relationship with the business being examined, and their mandate is to provide an objective, analytical view of the financial statements. Firms range from Big Four accounting firms (typically engaged on larger transactions) to regional and boutique M&A advisory accounting practices that specialize in middle and lower middle market due diligence.
The buyer typically engages and pays for the QofE. In some sell-side processes — particularly those managed by sophisticated advisors — the seller commissions a sell-side QofE before going to market, which they share with prospective buyers. A seller-commissioned QofE can accelerate the process and reduce buyer-side due diligence costs, but buyers should still carefully review any seller-commissioned analysis with appropriate skepticism and potentially supplement it with targeted buy-side review of specific areas of concern.
⏱️ Timeline and Cost of a QofE Review
For a lower middle market business in the $2M–$15M revenue range, a professional QofE review typically takes 3–6 weeks from initial data request to delivery of the report. The cost varies based on the complexity of the business, the quality and organization of the seller's financial records, and the scope of the review. Simple, single-entity businesses with clean, well-organized financials at the lower end of the revenue range may require $15,000–$25,000 in QofE fees. More complex businesses, or those with multiple entities, international operations, or significant inventory components, can cost $40,000–$75,000 or more.
These fees should be budgeted as a non-negotiable component of every acquisition process above $1M in enterprise value. The information a QofE provides — and the price adjustments and structure protections it enables — almost always produces a return that far exceeds the fee. Buyers who skip the QofE to save money typically regret it within 12 months of closing.

❓ Frequently Asked Questions
Is a QofE the same as an audit?
No. An audit provides an opinion on whether financial statements are fairly presented in accordance with GAAP. A QofE is an analytical investigation of the quality and sustainability of earnings — it goes deeper than an audit on specific items (EBITDA normalization, working capital, revenue quality) but does not provide an audit opinion. QofE reports are not replacements for audited financial statements where those are required.
Should I also get a sell-side QofE if I am selling my business?
A sell-side QofE can be a significant advantage for sellers. It demonstrates transparency and professionalism, reduces buyer uncertainty, accelerates the buyer's diligence process, and often reduces the scope of price renegotiations after LOI. Sellers who invest in a sell-side QofE before going to market often find that buyers are willing to move more quickly and with greater confidence than they would with un-reviewed financials.
What if the QofE shows the business earns less than represented?
This is the most common scenario where QofE creates significant deal value for the buyer. If normalized EBITDA is materially lower than what was represented in the seller's financial package, the buyer has the basis for a purchase price reduction. The magnitude of the reduction depends on the negotiated multiple and the size of the EBITDA discrepancy. Most experienced sellers expect some level of normalization; the key is whether findings are material and whether the parties can agree on their significance.
Final Thoughts
A Quality of Earnings report is not optional for serious business buyers — it is the standard of professional practice in the lower middle market. The QofE is how sophisticated buyers separate the businesses that perform as advertised from those that have been financially optimized for sale. Invest in the process, engage a reputable accounting firm, and treat every finding as valuable information rather than an obstacle. The buyers who close the best deals are the ones who know precisely what they are buying before they write the check.
