What is a Quality of Earnings (QoE) analysis?

A Quality of Earnings analysis is a formal, month-by-month examination of a business's trailing twelve months of financial performance, typically performed by an independent accounting firm. Unlike a standard financial audit, a QoE goes deeper — it examines individual transactions in a mini-audit format to determine whether the reported earnings are real, repeatable, and sustainable under new ownership.

The term "trailing twelve months" is also referred to as LTM (Lagging Twelve Months) or TTM (Trailing Twelve Months) in M&A practice. A QoE report normalizes the financials by removing one-time events, owner-specific expenses, and accounting choices that distort the true economic picture of the business.

In the lower middle market (businesses valued between $1M and $25M), a QoE analysis is the single most important piece of financial due diligence a buyer can perform. It answers the fundamental question every lender and buyer needs answered: "Are the earnings real, and will they continue after the seller leaves?"

How does a QoE differ from SDE recasting?

A QoE analysis and an SDE recast are fundamentally different exercises in scope, rigor, and purpose — though many first-time acquirers confuse the two. SDE (Seller's Discretionary Earnings) recasting is a buyer's internal calculation that adds back the owner's salary, benefits, and personal expenses to net income to estimate total owner benefit. It is typically done on a spreadsheet using the seller's reported financials at face value.

A QoE analysis, by contrast, does not take the seller's numbers at face value. It independently reconstructs earnings by tracing transactions back to source documents — bank statements, tax returns, general ledger entries, invoices, and contracts. Where an SDE recast asks "what did the seller report?", a QoE asks "what actually happened?"

The practical difference is significant. An SDE recast might show $400,000 in owner benefit based on the seller's P&L. A QoE analysis of the same business might reveal that $60,000 of reported revenue was actually intercompany transfers, that $35,000 in "one-time" legal expenses recurred three years running, and that the owner's health insurance was understated because a family member was employed solely for benefits. The QoE-adjusted number might come in at $305,000 — a 24% reduction that fundamentally changes the deal economics.

What does a QoE report examine?

A comprehensive QoE report examines seventeen distinct areas of a business's financial performance, organized into phases that build on each other. The analysis begins with revenue quality — verifying that reported revenue matches bank deposits and examining customer concentration, recurring revenue percentages, and revenue trend sustainability.

The core financial model reconstructs earnings using a deterministic approach: raw financial data is computed through pure arithmetic (Revenue, COGS, Gross Profit, Operating Expenses, Owner Compensation, EBITDA, and Reported SDE), then each expense line item is classified against an established addback taxonomy. This taxonomy includes eight categories: Owner Compensation (always normalized), Owner Perquisites (always added back), Family Payroll (always added back), Related-Party Transactions (adjusted to market rate), Non-Recurring Expenses (added back with verification), Non-Cash Expenses (selectively adjusted), Below-the-Line items (often missed by buyers), and Aggressive or Red Flag items (rejected and flagged).

Beyond the income statement, a QoE examines working capital requirements (the cash needed to run the business day-to-day), balance sheet integrity, proof of cash (matching bank deposits to reported sales for 24+ months), capital expenditure patterns, customer concentration risk, and debt and lease obligations. Each section produces specific findings, red flags, and adjustments that feed into the final adjusted earnings figure.

When do you need a QoE analysis?

Every acquisition above $500,000 in purchase price should have a QoE analysis — full stop. Below that threshold, a thorough SDE recast with proof of cash verification may be sufficient, but the buyer accepts more risk. For SBA-financed acquisitions, many preferred lenders now require or strongly recommend a QoE report as part of their underwriting package.

The ideal timing is after the Letter of Intent (LOI) is signed but before the Purchase Agreement is executed. The LOI typically grants the buyer an exclusivity period of 60-90 days for due diligence, and the QoE should be one of the first workstreams initiated. A QoE typically takes 3-6 weeks to complete depending on the complexity of the business and the responsiveness of the seller in providing documents.

There are situations where a QoE is non-negotiable: businesses with complex revenue recognition (subscription, contract, or project-based), businesses with significant owner add-backs (greater than 30% of reported SDE), businesses where the seller has operated with a tax-minimization strategy for years, franchise businesses with royalty and marketing fund obligations, and any business where the buyer is using leverage (debt) to finance more than 50% of the purchase price.

What does a QoE analysis cost?

A buy-side QoE analysis for a lower middle market transaction typically costs between $15,000 and $50,000, with most small business acquisitions ($1M-$5M purchase price) falling in the $15,000-$25,000 range. The cost scales with the complexity of the business, the number of revenue streams, the quality of the seller's bookkeeping, and the number of years being analyzed.

For context, on a $2M acquisition, a $20,000 QoE represents 1% of the purchase price. If the QoE identifies even a single significant adjustment — say, $40,000 in overstated earnings that reduces the valuation by $120,000 at a 3x multiple — the ROI is 6:1 on the QoE investment. In practice, QoE analyses identify material adjustments in the majority of deals.

Sellers can also commission a sell-side QoE (sometimes called a "vendor due diligence" report) before going to market. This costs roughly the same but serves a different purpose: it identifies and addresses issues before buyers discover them, which preserves deal momentum and often results in a higher sale price because buyers have more confidence in the numbers.

What are common QoE adjustments?

QoE adjustments fall into two broad categories: normalizing adjustments (removing items that won't continue under new ownership) and pro forma adjustments (reflecting changes the buyer plans to make). The most frequently identified adjustments in lower middle market transactions, based on analysis of hundreds of deal patterns, include:

Owner compensation normalization is the largest adjustment in nearly every small business QoE. The current owner may take a salary of $40,000 while performing a role that would cost $90,000 to replace — or conversely, may take $250,000 in salary plus distributions while the role requires only $80,000. The QoE normalizes this to a market-rate general manager salary.

Owner perquisites — personal vehicles, travel, meals, cell phones, home office expenses, club memberships, and personal insurance run through the business — are added back because they won't continue under a new owner or will be replaced at different levels. Family payroll for non-working or underworking family members is added back entirely. Related-party transactions (rent paid to the owner's real estate LLC, services purchased from the owner's other businesses) are adjusted to market rates.

Non-recurring expenses require a four-part verification: Was it truly one-time? Did it occur in only one of the trailing three years? Is there a documented reason it won't recur? Would a reasonable buyer agree it's non-recurring? Many sellers classify recurring expenses as "one-time" — legal fees, equipment repairs, and marketing campaigns that happen every year are not add-backs regardless of how the seller categorizes them.

How does Dealright approach Quality of Earnings?

Dealright's AI-powered QoE engine uses a three-stage deterministic pipeline that combines the consistency of automated computation with the judgment of expert classification. Stage one is pure arithmetic — the system queries all financial data from uploaded documents, deduplicates across sources using a priority hierarchy (P&L over Tax Returns over Balance Sheet), groups by fiscal year, and computes all standard metrics through code. The same input produces the same output every time, eliminating the variance that occurs when different analysts manually build financial models.

Stage two applies a single expert AI classification pass to the deterministic model. Every operating expense line item is evaluated against an eight-category addback taxonomy derived from Wall Street Prep QoE methodology and practitioner training frameworks. Each proposed adjustment must reference a specific taxonomy category, cite a source document, and for non-recurring items, must state whether a three-year recurrence test passes. Empty adjustment arrays are valid output — the system does not invent adjustments to justify its existence.

Stage three applies the classified adjustments through code: filtering duplicates, computing Adjusted EBITDA, Normalized SDE, and Buyer's Cash Flow. The result is a comprehensive seventeen-section report covering everything from revenue quality to customer concentration to working capital analysis.

Dealright has validated this pipeline across multiple test deals, achieving a coefficient of variation under 7% across repeated runs — within the range of disagreement between human CPAs analyzing the same business.
