Quick Answer: A Quality of Earnings (QOE) report is an independent financial analysis prepared during M&A due diligence to assess whether a company’s reported earnings reflect sustainable performance. Performed by a CPA firm, it adjusts EBITDA, reviews revenue quality, examines working capital, and identifies risks that affect valuation. A QOE often directly influences the final purchase price, deal structure, and whether a transaction closes at all.
What Is the Quality of Earnings?
The quality of earnings refers to how sustainable, reliable, and repeatable a company’s reported earnings actually are. A business can report a healthy profit on its income statement and still have low-quality earnings if much of that profit came from one-time events, aggressive accounting choices, owner add-backs, or other items that will not recur for a future buyer.
A Quality of Earnings analysis, often abbreviated as QOE, is the formal process used during M&A due diligence to answer one question: are these earnings real, and will they continue? It is performed by an independent third party, typically a CPA firm with a dedicated transaction advisory practice, and it produces a detailed report used by buyers, sellers, and lenders to make decisions about the deal.
In short, “what is the quality of earnings” really comes down to whether a buyer can trust the earnings number to project forward. A QOE answers that.
QOE vs. Audit: A Critical Distinction
The single most common confusion about a Quality of Earnings analysis is whether it is the same as an audit. It is not, and understanding the difference matters.
A financial audit is retrospective and compliance-focused. Its purpose is to verify that historical financial statements accurately reflect the business in accordance with Generally Accepted Accounting Principles (GAAP). An audit produces an opinion on whether the numbers are fairly stated.
A Quality of Earnings analysis is forward-looking and strategic. Its purpose is not to verify GAAP compliance but to assess whether the earnings the business reports are sustainable, normalized, and a fair basis for projecting future performance. A QOE asks: will the next owner of this business actually realize these earnings?
The two overlap in some procedures (both look at financial records), but their goals, scope, timing, and reports are different:
- Purpose: an audit verifies accuracy; a QOE assesses sustainability.
- Timing: audits happen annually; QOEs happen during a specific M&A due diligence window.
- Output: an audit produces an auditor’s opinion; a QOE produces a detailed report (often a spreadsheet workbook with 30 to 50 tabs, sometimes summarized in a presentation deck) with adjustments, observations, and recommendations.
- User: an audit serves regulators and stakeholders broadly; a QOE serves an acquirer (or a seller preparing for sale) making a specific transaction decision.
A clean audit does not substitute for a QOE, and almost every sophisticated buyer commissions a QOE regardless of the audit history.
What Goes Into a Quality of Earnings Report
A QOE report is not a single number. It is a detailed analysis spanning multiple dimensions of the business. A well-structured Quality of Earnings report typically covers:
- Adjusted EBITDA. The analyst recasts reported EBITDA to remove non-recurring items, owner discretionary expenses, and accounting anomalies that would not continue under new ownership. This adjusted figure becomes the basis for valuation.
- Revenue quality and recognition. Are sales real, recurring, and properly timed? The analyst looks for aggressive recognition practices, channel stuffing, customer concentration risk, and contract sustainability.
- Proof of cash. A reconciliation between reported revenue and the cash that actually arrived in bank accounts. A common red flag in lower-quality deals.
- Working capital trends. How much working capital does the business actually need to operate, and how has it moved? This affects both the purchase price and the working capital target written into the definitive agreement.
- Non-recurring items. Restructuring charges, litigation costs, gains or losses from asset sales, COVID-era distortions, anything that pulled earnings up or down in a way that won’t repeat.
- Customer and vendor concentration. Heavy reliance on a few customers or suppliers, or on a single key employee, all show up as risks in a QOE.
- Operational diligence. Workforce age, key-person dependence, equipment condition and capital expenditure needs, profit margin by customer or product, and seasonal patterns.
- Forward-looking analysis. A review of management’s projections, the assumptions behind them, and whether they hold up against the historical baseline the QOE establishes.
The finished product gives a buyer (and increasingly a seller, on a pre-sale QOE) a defensible picture of what the business actually earns and what the next owner can reasonably expect.
Why a QOE Matters in a Business Acquisition
A Quality of Earnings analysis is often the most consequential piece of work in the entire due diligence process, for several specific reasons.
It validates or challenges the purchase price. The QOE establishes adjusted EBITDA, which is what the buyer’s valuation multiple is applied to. A finding that reduces adjusted EBITDA by 10% translates directly into a 10% reduction in indicated value. This is why QOE findings so frequently trigger price renegotiation.
It shapes deal structure. Discoveries from a QOE often result in changes to working capital targets, indemnity provisions, earnouts, escrow amounts, or representations and warranties in the definitive agreement. A buyer concerned about a specific risk uses the QOE to structure protection around it.
It surfaces deal-killing risks early. Material accounting issues, customer concentration the seller downplayed, or non-recurring items that propped up reported earnings all come out during a QOE. Catching them at this stage is far less expensive than discovering them after closing.
Lenders increasingly require it. Most senior lenders financing M&A deals expect to see a QOE before they commit. For SBA-financed transactions and lower middle market deals, this is becoming standard.
Quality of Earnings Ratio: The Underlying Concept
A separate but related concept is the quality of earnings ratio, which compares a company’s net income to its cash flow from operations. The general rule: the closer the ratio is to 1, or above, the more cash is backing the reported earnings, and the higher the quality. A ratio significantly below 1 suggests reported earnings are not converting to cash, a classic warning sign of low earnings quality.
A QOE report does not stop at this ratio, but the principle behind it, that real earnings should generate real cash, runs throughout the analysis. The “proof of cash” reconciliation discussed above is one practical expression of the same idea.
Sell-Side vs. Buy-Side QOE
QOE reports come in two flavors, depending on who commissions them and why.
A buy-side QOE is commissioned by an acquirer (a strategic buyer, a private equity firm, or a lender) during their due diligence after a letter of intent is signed. It is part of the buyer’s investigation and almost always results in some negotiation back with the seller, sometimes a price reduction, sometimes a structural change, occasionally a walk-away.
A sell-side QOE is commissioned by the seller before going to market, or at least before serious buyer engagement. The logic: rather than wait for a buyer to discover surprises during their diligence and use them to negotiate down, a seller proactively identifies and addresses issues, presents a defensible adjusted EBITDA, and accelerates the buyer’s diligence work. A sell-side QOE often pays for itself many times over in stronger offers, faster closings, and reduced renegotiation.
For sellers preparing for a sale, the sell-side QOE has become an increasingly standard part of the confidential information memorandum and broader pre-market preparation, particularly for deals in the lower middle market and above.
What Does a QOE Cost?
QOE costs vary widely based on the size and complexity of the business, the scope of work, and the firm performing the analysis. Rough current market ranges: roughly $12,000 to $25,000 for small businesses, $25,000 to $60,000 for lower middle market deals, and $60,000 to six figures or more for larger middle market transactions. Engagements typically take 30 to 45 days from start to delivery, depending on how quickly the seller supplies underlying information.
The relevant comparison is rarely the absolute fee. A QOE finding that protects a 5% purchase-price adjustment on a $20 million deal pays for itself dozens of times over.
How a QOE Fits Into Selling Your Business
For owners thinking about a sale, the question is no longer whether a QOE will be involved, it will be. The real question, what is the quality of earnings the business will look like to a buyer, is one the seller has the chance to answer first if they choose to. The proactive path has measurable advantages: it supports a stronger valuation, reduces the negotiation room a buyer’s QOE creates, and signals to sophisticated buyers that the seller is serious and well-prepared.
This is part of the same broader work that includes a defensible business valuation and clean financial records (including a proper accounting of Seller’s Discretionary Earnings for smaller businesses). Each piece reduces buyer-perceived risk, and reduced risk translates directly into price.

What is the Quality of Earnings: FAQs
What does QOE stand for?
QOE stands for Quality of Earnings. In finance and M&A, it refers to the sustainability, reliability, and repeatability of a company’s reported earnings, and to the formal third-party analysis performed during due diligence to assess that quality.
What is a Quality of Earnings report?
A Quality of Earnings report is a financial due diligence analysis prepared by an independent CPA firm during an M&A transaction. It adjusts EBITDA, examines revenue quality and working capital, identifies non-recurring items and risks, and produces a defensible picture of the company’s true earning power. Buyers, sellers, and lenders all rely on QOE reports to inform deal decisions.
What is the difference between a Quality of Earnings and an audit?
A financial audit verifies that historical financial statements are accurate and GAAP-compliant; it is retrospective and compliance-focused. A QOE assesses whether reported earnings are sustainable and reliable as a basis for future performance; it is forward-looking and strategic. A clean audit does not replace a QOE, and most sophisticated buyers commission a QOE regardless of audit history.
Who pays for a Quality of Earnings analysis?
It depends on whether it is a buy-side or sell-side QOE. A buy-side QOE is commissioned and paid for by the acquirer as part of their due diligence. A sell-side QOE is commissioned and paid for by the seller, typically before going to market, to identify and address issues proactively. Both have become standard in mid-market M&A.
How much does a Quality of Earnings report cost?
Costs vary by business size and complexity. For small businesses, $12,000 to $25,000 is typical. Lower middle market deals usually run $25,000 to $60,000, and larger middle market transactions can reach six figures. The cost is usually measured against the deal value: catching a single material issue almost always pays for the analysis many times over.
When in the M&A process does a QOE happen?
A buy-side QOE typically begins after a letter of intent is signed, during the due diligence phase, and takes 30 to 45 days. A sell-side QOE happens earlier, before the business goes to market, as part of the seller’s pre-sale preparation.
What is the quality of earnings ratio?
The quality of earnings ratio compares a company’s net income to its cash flow from operations. A ratio at or above 1 suggests earnings are well-backed by cash; a ratio significantly below 1 is a warning that reported earnings are not converting to cash. A full QOE goes well beyond this single ratio, but the principle, that real earnings should generate real cash, is central to QOE analysis.
