The Quality of Earnings Report: Why Performing a Reverse Due Diligence Audit Before Going to Market Saves Deals from Collapsing

By Chapman Syme, Managing Director — Blackland Advisors Category: Underwriting

In the lower middle market, more transactions collapse during due diligence than at any other stage of the sale process. The buyer has signed a letter of intent, exclusivity has been granted, and both parties have invested weeks or months of time and significant professional fees. Then the buyer's quality of earnings team begins its work — and finds something. A variance between the financial statements and tax returns that no one can explain. An add-back that doesn't hold up under scrutiny. A revenue recognition policy that accelerates income in a way the buyer's analysts flag as aggressive. A customer relationship that turns out to be more fragile than the marketing materials suggested.

None of these findings is necessarily fatal. But each one erodes buyer confidence, extends the timeline, and creates an opportunity for renegotiation that a prepared seller would have foreclosed entirely by discovering the issue first. That is exactly what a sell-side quality of earnings report does. It is the most effective single investment a lower middle market seller can make before going to market — not because it makes problems disappear, but because it converts buyer-discovered surprises into seller-disclosed knowns, and in doing so, fundamentally changes the negotiating dynamic in the seller's favor.

This article focuses specifically on the sell-side QoE. If you want to understand the broader financial preparation framework that surrounds it — including how to organize historical records, normalize working capital, and build credible pro forma projections — our guide on how to prepare your financials for a business sale covers all five dimensions in full.

What a Quality of Earnings Analysis Actually Is

The Buyer-Side QoE and Why Sellers Need Their Own

A quality of earnings analysis is an independent financial review conducted by an accounting firm that examines whether a company's reported earnings are recurring, sustainable, and accurately presented. In most institutional M&A transactions, the buyer commissions a QoE as part of their diligence process. The firm's analysts examine the financial statements, tax returns, and management reports in detail, test the add-backs claimed in the normalization schedule, assess revenue quality and customer concentration, and produce an independent view of normalized EBITDA that may differ from the seller's presentation.

The buyer-side QoE is designed to serve the buyer's interests — to find issues that justify price reductions, deal restructuring, or in some cases deal termination. A sell-side QoE, commissioned by the seller before going to market, serves the seller's interests: it identifies the same issues the buyer's team would find, gives the seller the opportunity to address them or develop a clear explanatory narrative, and produces a financial presentation that has already been stress-tested from the buyer's perspective.

"The difference between a buyer discovering a financial issue in week eight of diligence and the seller disclosing it in week one is not just timing. It is the difference between a crisis of trust and a managed conversation."

What the Analysis Covers

A comprehensive quality of earnings analysis typically covers: the reconciliation of reported net income to normalized EBITDA, including documentation and testing of all claimed add-backs; revenue quality analysis, examining whether revenue is recurring, whether it is recognized in accordance with the company's stated policies, and whether there are any one-time or unusual items inflating recent periods; customer and revenue concentration analysis; gross margin analysis by product, service, or customer segment; working capital analysis, establishing the normalized working capital level that will serve as the basis for the purchase price adjustment at close; and an assessment of any known legal, compliance, or operational issues that would surface in a buyer's standard diligence.

The resulting report is typically 50–150 pages depending on the complexity of the business, and it becomes one of the most carefully reviewed documents in any subsequent buyer diligence process. Sellers who can provide a sell-side QoE to interested buyers at the outset of diligence are signaling a level of preparation and transparency that immediately distinguishes them from sellers presenting unaudited management financials with a handwritten add-back schedule.

The normalized EBITDA figure that the QoE produces and defends is also the number on which a buyer's valuation multiple is applied. Understanding what goes into that calculation — and how buyers stress-test every component of it — is essential context before commissioning the work. Our complete guide What Is EBITDA? covers every element of the calculation, from the treatment of depreciation and interest to the two-step owner compensation normalization process, and explains precisely why the difference between reported and normalized EBITDA can be worth millions in a transaction.

What Sell-Side QoEs Actually Find — and What That Means for Sellers

The Add-Backs That Don't Survive Scrutiny

One of the most common findings in a sell-side QoE is that some portion of the claimed add-backs — items the owner and their accountant identified as legitimate normalizations — do not hold up under independent examination. A "one-time" legal expense that has appeared in the general ledger three years running. An owner compensation add-back that implies a replacement CEO cost far below what the market actually pays for comparable roles. A personal expense categorization that requires the seller to argue that a vehicle primarily used by a family member is a business asset.

Discovering these issues in a sell-side QoE, rather than in a buyer's diligence, allows the seller to make a deliberate choice: remove the add-back from the normalization schedule and present a more conservative but more defensible EBITDA figure, or retain the add-back with improved documentation and a more carefully constructed rationale. Either path is available when the seller controls the discovery. Neither is available gracefully when the buyer's team finds the problem mid-process.

Our dedicated guide Understanding Add-Backs: How Business Owners Maximize Valuation Before a Sale covers every add-back category in depth — including the documentation standard required to defend each one, the add-backs most likely to be challenged in a QoE, and the reclassification strategy some sellers use before going to market to convert a large add-back schedule into verified taxable income. Reading it before commissioning a sell-side QoE will help you arrive at that process with realistic expectations about which adjustments will survive scrutiny and which will require additional work.

Revenue Quality Issues That Create Valuation Compression

Revenue quality analysis frequently surfaces issues that sellers did not know were problems: a period of elevated revenue attributable to a single large order from a customer that did not repeat; a revenue recognition policy that is technically permissible but that concentrates income into periods that make the trailing twelve months look better than the underlying business trend; unbilled revenue that has been accruing in a way that inflates the most recent period; or customer relationships that are categorized as "long-term" but that on examination are purchase-order-by-purchase-order arrangements with no contractual commitment.

Each of these findings, in the hands of a buyer's quality of earnings team, becomes an argument for reducing the normalized EBITDA — and therefore the purchase price — below the seller's original presentation. In the hands of the seller's own team, each finding is an opportunity to develop an explanatory narrative, provide supporting documentation, or in some cases restructure customer arrangements before going to market in ways that improve the quality and defensibility of the revenue base.

Customer concentration is a particularly consequential finding in revenue quality analysis, because it affects not just the EBITDA calculation but the multiple a buyer is willing to apply. A business with 40% of revenue from a single customer may generate strong absolute EBITDA, but buyers will compress the multiple to reflect the concentration risk. Understanding how buyers assess this — and what specifically you can do to address it before going to market — is covered in our post on business valuation drivers, which examines customer concentration alongside four other core factors that expand or compress valuation multiples in lower middle market transactions.

The normalization schedule as a deliverable: The primary output of a sell-side QoE that sellers use directly in a transaction is the normalization schedule — a documented presentation of every adjustment from reported net income to normalized EBITDA, with supporting rationale and documentation for each line item. This schedule becomes part of the information package provided to buyers and serves as the basis for all subsequent EBITDA discussions. A normalization schedule produced by an independent accounting firm carries considerably more credibility than one prepared internally by the seller or their bookkeeper.

The Cost-Benefit Analysis: When Does a Sell-Side QoE Make Sense?

What It Costs

A sell-side quality of earnings engagement typically costs $25,000–$75,000 for lower middle market businesses, depending on the size and complexity of the business, the number of years of financials reviewed, and the accounting firm engaged. Larger or more complex businesses — those with multiple entities, significant inventory, complex revenue recognition, or international operations — may require more extensive work at the higher end of that range or above.

This is a meaningful absolute expenditure, and sellers reasonably ask whether it is worth it. The answer, in the vast majority of lower middle market transactions, is yes — and the math is straightforward. A sell-side QoE that identifies $200,000 in legitimate add-backs that the seller would not otherwise have documented generates $1–2 million in additional enterprise value at typical lower middle market multiples. A sell-side QoE that prevents a mid-diligence renegotiation that would have reduced the purchase price by $500,000 is worth many times its cost. And a sell-side QoE that identifies a revenue quality issue that would have caused the buyer to walk away — and gives the seller the opportunity to address it before going to market — is worth the entire transaction value it preserved.

This same logic underlies several of the deal-killers we examine in our post on five deal-killers that collapse business sales. Financial inconsistency is the first and most common of those five — and a sell-side QoE is the most direct and effective prevention for it. Sellers who read that post alongside this one will recognize that the QoE is not merely a financial exercise; it is the single most targeted investment for eliminating the category of risk most likely to derail a lower middle market transaction.

When to Commission the Report

The optimal timing for a sell-side QoE is twelve to eighteen months before the target transaction date — early enough that findings can be addressed operationally, not just explained away. A sell-side QoE commissioned six months before going to market is still highly valuable for its documentation and presentation function, but it leaves less time to address underlying issues that the analysis surfaces. A sell-side QoE commissioned in the final weeks before a transaction is launched is primarily a defensive exercise — it reduces the risk of buyer-discovered surprises but does not provide the operational runway to fix the issues it finds.

One timing mistake to avoid: Commissioning a sell-side QoE in the same fiscal year you are going to market, if the analysis significantly alters your EBITDA presentation, can create the appearance that you adjusted your financials in preparation for sale. Buyers notice changes in normalization methodology that coincide with a sale process. If the sell-side QoE will produce a meaningfully different EBITDA figure than what has historically been reported, the earlier you commission it — and the cleaner the transition period before going to market — the more credible the revised presentation will be.

This timing consideration is one of several reasons why the window between deciding to sell and actually going to market matters so much. Our post on the cost of waiting to sell your business examines the broader consequences of compressing that preparation window — including how declining financials in the trailing period, owner disengagement, and market cycle shifts interact with the kind of preparation the QoE requires. Sellers who start early have options. Sellers who start late are managing damage.

Frequently Asked Questions

What is a quality of earnings report in M&A?

A quality of earnings (QoE) report is an independent financial analysis conducted by an accounting firm that examines whether a company's reported earnings are recurring, sustainable, and accurately presented. It tests the normalization adjustments claimed by the seller, assesses revenue quality, examines working capital dynamics, and produces an independent view of normalized EBITDA. In most institutional M&A transactions, buyers commission a QoE as part of their diligence. A sell-side QoE is the same analysis commissioned by the seller before going to market, so that findings can be addressed proactively rather than discovered by the buyer mid-process.

Why would a seller commission their own quality of earnings report?

A sell-side QoE converts buyer-discovered surprises into seller-disclosed knowns. Every issue that a buyer finds in diligence erodes trust, extends the timeline, and creates grounds for price renegotiation. Every issue the seller discloses proactively — with documentation and a clear explanatory narrative — is a managed conversation rather than a crisis. Sellers who arrive at diligence with a completed sell-side QoE consistently experience faster processes, fewer post-LOI renegotiations, and stronger final outcomes than those who do not.

How much does a sell-side quality of earnings report cost?

A sell-side QoE typically costs $25,000–$75,000 for lower middle market businesses, depending on complexity and scope. This is almost always recovered many times over through one or more of three mechanisms: legitimate add-backs identified and documented that increase the defensible EBITDA figure; prevention of mid-diligence renegotiations that would have reduced the purchase price; and identification and resolution of revenue quality or financial presentation issues that, if discovered by the buyer, would have provided grounds for a price reduction or deal termination.

What does a quality of earnings analysis actually examine?

A comprehensive QoE covers the reconciliation of reported net income to normalized EBITDA with testing of all add-backs; revenue quality analysis examining recurring vs. non-recurring revenue, recognition policies, and customer concentration; gross margin analysis by segment; working capital dynamics and normalization; and an assessment of any known legal, compliance, or operational issues. The output is typically a 50–150 page report that becomes one of the most carefully reviewed documents in any subsequent buyer diligence process.

When should I commission a sell-side QoE before selling my business?

The optimal timing is twelve to eighteen months before the target transaction date — early enough to address any findings operationally, not just explain them. A QoE commissioned six months before going to market still provides significant value for documentation and presentation purposes but leaves less runway to fix underlying issues. Commissioning a QoE in the same fiscal year you plan to go to market, if it significantly changes your EBITDA presentation, can create the appearance of financial adjustment in preparation for sale, which buyers will scrutinize carefully.

What happens if the sell-side QoE finds problems?

Finding problems is exactly what the sell-side QoE is designed to do — and finding them before the buyer does is the entire point. When the analysis surfaces an issue, the seller has three choices: address it operationally before going to market; disclose it proactively with documentation and a clear explanatory narrative that minimizes its impact on the buyer's assessment; or remove the relevant add-back from the normalization schedule and present a more conservative but more defensible EBITDA figure. All three paths are available when the seller controls the discovery. None are available gracefully when the buyer's team finds the issue independently.
