Quality of Earnings (QoE) Report: What It Is, Cost, Audit vs. QoE, and How SMB Buyers Use It
If you are a self-funded searcher or first-time small business buyer, this QoE guide is for you.
It covers the six questions that can change price, terms, and risk in a deal. Each section stands alone, so you can read one answer without reading the rest.
Quick Answers
Six common QoE questions under LOI timelines:
What is a QoE in M&A? A transaction-focused analysis of the sustainable earnings you are really buying. (Jump to QoE in M&A)
What is the difference between audit and QoE? Audit tests whether financial statements are free of material misstatement, while QoE tests sustainable deal earnings. (Jump to Audit vs. QoE)
How much does a quality of earnings report cost? Cost follows scope, complexity, and deliverables. (Jump to QoE cost)
What is a quality of earnings report? It is a third-party diligence report that normalizes earnings and flags risks. (Jump to What is a QoE report)
Quality of earnings report for small business acquisition: Consider it when add-backs, cash, or working capital assumptions materially affect value. (Jump to Do you need QoE)
Who provides quality of earnings services? Choose a provider who works in your deal size and delivers findings you can act on. (Jump to Who provides QoE)
If someone says “audited,” start with audit vs. QoE. If you are under LOI, start with when to run QoE. For cost, start with pricing.
What is a Quality of Earnings Report?
A quality of earnings report is an independent financial due diligence report that evaluates whether reported earnings reflect sustainable operating performance.
It typically normalizes earnings and highlights issues that can affect valuation.
What a QoE Report Typically Includes
Normalized earnings baseline: Often expressed as adjusted EBITDA, a common deal earnings measure.
Revenue quality: One-off sales, timing effects, or customer concentration.
Expense quality and add-backs: Determines which adjustments are supported and truly nonrecurring.
Cash validation where needed: A Proof-of-Cash reconciliation ties reported results to bank activity.
Risks summary: Flags issues that can change how you price or structure the deal.
If a seller presents “adjusted EBITDA” with add-backs, the QoE report tests which add-backs are supported and truly nonrecurring.
QoE report vs. QoE ratio
A QoE report is a transaction diligence deliverable used in a deal to test sustainable earnings. The quality of earnings ratio is a separate metric that compares operating cash flow to net income.
If you are hiring diligence for an acquisition, specify that you want a quality of earnings report rather than a ratio calculation.
How a QoE Engagement Typically Works
Most QoE work follows a simple flow, from documents to an earnings bridge.
You provide historical financials and source documents.
The provider analyzes earnings drivers and ties key numbers to support.
You receive an earnings bridge plus a risk summary.
The most common causes for delay here are missing documentation and slow seller responses.
What “Good” Looks Like in a QoE Deliverable
Use these markers to judge whether the report will be useful in real negotiations.
A clear path from reported results to normalized earnings, with each adjustment explained.
Tie-outs to source documents for key numbers.
Risks explained as decision points.
A report that a non-financial buyer can use without heavy translation.
Three Misconceptions on Quality of Earnings Report to Set Aside
“A QoE report is the same as an audit.” It is not. An audit provides reasonable assurance on financial statements, while a QoE is transaction-focused diligence and does not provide audit-level assurance.
“A QoE guarantees future earnings.” It does not. It tests sustainability signals and risks using historical data.
“All add-backs are valid if the seller says so.” They are not. Add-backs need support and a clear case for why they should not repeat.
Quick Decision Rules
If the purchase price is based on EBITDA or SDE, insist on a defensible baseline.
If cash does not track reported revenue, prioritize Proof of Cash validation.
If you cannot describe the deliverable you will receive, ask for a sample.
Before you commit, request a sample deliverable and confirm it includes an earnings bridge, cash validation when needed, and a risk summary you can act on. See a sample report format here: Quality of Earnings Report.
What is a QoE in M&A?
A QoE in M&A is transaction diligence that helps buyers translate reported results into a sustainable earnings baseline for valuation and underwriting. It reduces information gaps and surfaces risks that can change price or terms. In practice, a QoE often:
Surfaces the information asymmetry. The seller knows the business, and the buyer is quickly catching up.
Tests the earnings measure used in valuation. In many deals, that is adjusted EBITDA.
Can affect deal terms. Findings can support renegotiation on price, working capital expectations, or other deal protections.
Make working capital visible. In deal terms, working capital is the cash the business needs tied up to operate after close.
Explains how audited financials can exist, and QoE can still be needed. They answer different questions in a transaction.
For example, a seller deck can highlight "one-time" cost savings that look nonrecurring on paper. QoE tests whether those savings actually hold, or whether you are paying a multiple on earnings that will not repeat.
Common Misconceptions on QoE in M&A
“QoE is only for PE and big deals.”Guardian Due Diligence offers QoE for SMB transactions, including deals in the $1M to $45M range.
“QoE is just rebuilding EBITDA.” In M&A, it also addresses sustainability questions and working capital considerations that affect deal decisions.
Quick Decision Rules
If your valuation is a multiple of earnings, you need a baseline you can explain and defend.
If the business is working-capital-heavy, insist on a working capital view before you finalize terms.
Start by writing down the 3 to 5 assumptions your valuation depends on, and validate whether each is recurring and supportable.
What is the Difference Between Audit and QoE?
The difference between audit and QoE is purpose and assurance. An audit is designed to obtain reasonable assurance that financial statements are free of material misstatement, while a QoE is a transaction-focused analysis of sustainable earnings and does not provide audit-level assurance.
What an audit is built to answer: Are the financial statements fairly stated, in all material respects?
What a QoE is built to answer: What earnings are recurring and supportable for valuation in a transaction?
What an audit usually does not do for buyers: Validate add-backs, normalize earnings for valuation, size working capital needs, or reconcile cash to revenue for deal underwriting.
Why both can exist in one deal: Audited statements can still leave open the deal question of sustainable earnings.
Say, for example, the seller has audited statements, but the valuation depends on add-backs. A QoE validates which add-backs are documented and truly nonrecurring.
Two Misconceptions on Audit vs. QoE
“QoE is an audit-lite.” It is not. A QoE typically provides no audit or review assurance.
“An audit tells me what earnings I am buying.” An audit addresses financial statement misstatements. QoE addresses transaction underwriting questions.
Quick Decision Rules
If your question is “Are these statements fairly stated?” choose an audit.
If your question is “What earnings can I pay for?” choose QoE.
If you are using leverage and need a lender-ready earnings analysis, prioritize transaction-focused earnings analysis.
Ask your lender or advisor which question they need answered, statement reliability or sustainable earnings, and choose the work accordingly.
If cash validation is a concern, review a Proof of Cash sample to see what gets reconciled.
How Much Does a Quality of Earnings Report Cost?
The cost of a quality of earnings report varies with scope and complexity. A fair way to compare quotes is to compare scope: what gets tested, how far back, and what deliverable you receive.
Start by separating three things:
Published pricing (a provider’s listed tiers)
Market ranges (sourced ranges from other firms)
Your quote drivers (what your deal requires and how clean the data is)
Guardian Due Diligence has three tiers for deals under a $2 million purchase price, with larger deals priced slightly higher:
QoE Light at $20k: Excel-only analysis. Covers the trailing period back to 2021. Includes standard QoE scope, trailing twelve-month EBITDA, and working capital analysis.
QoE at $25k: Full written QoE report. Accepted by banks, SBA lenders, and equity investors. The most commonly requested tier.
Advised QoE at $40k: Everything in the QoE tier plus 10 advisory hours with the lead analyst, projection model support, business plan support, key man risk assessment, and a 65-item red flag checklist.
What drives your QoE cost is usually visible early:
Data quality: Incomplete schedules and weak support can add cleanup and validation work.
Accounting method and complexity: More complex books, inventory-heavy operations, and multi-entry structures add scope.
Deliverable depth: An Excel-only analysis is not the same scope as a written report.
Speed: Tight deadlines can add cost.
For example, two $2M deals can price differently. This can be because one has clean monthly financials and reconciled bank statements, while the other has gaps that require rebuilding support before results can be trusted.
Timeline Norms and What Slows Them Down
A typical QoE report takes four to six weeks, depending on scope and data quality. In SMB deals, three to four weeks after a letter of intent (LOI) is possible with a responsive seller.
The full report can take weeks, but major issues can surface early. Guardian Due Diligence finds 85% of major deal-breaking issues within 7 days.
Misconceptions on QoE Report Cost
“There is a standard price for QoE.” There is not. Published ranges vary, and the scope drives the quote.
“The cheapest quote is safest.” A shallow scope can miss the point of the work.
If you need a deliverable that a non-financial buyer can read and act on, choose a tier that includes a written report. If seller documents and add-back support are disorganized going in, build a timeline buffer in early.
Get the scope in writing before comparing QoE prices. Confirm years covered, cash validation, working capital, and deliverable format.
Cost only matters after you know whether your deal actually needs QoE and when to run it.
Quality of Earnings Report for Small Business Acquisition: Do You Need One (And When)?
A quality of earnings report for a small business acquisition is most useful when the price is tied to EBITDA or SDE, and you plan to repay debt from cash flow. It helps you test whether the earnings you are underwriting are real and repeatable.
Strong reasons to run QoE in an SMB deal include:
Add-backs drive the valuation. The earnings story depends on adjustments.
Books are inconsistent or late. Month-to-month reporting does not hold together.
Cash does not track revenue. Deposits and bank activity do not line up with sales.
Working capital is heavy. Inventory or receivables tie up cash after close.
You are a first-time buyer and need findings translated into clear deal decisions.
If the P&L looks strong but deposits do not reconcile cleanly to reported revenue, prioritize cash validation early in diligence.
When to Run QoE and Why “Early” Matters
Run QoE soon after a letter of intent (LOI), while you can still change price, terms, or walk away. In SMB deals, three to four weeks can be a realistic timeline once diligence is underway, and it often depends on seller responsiveness.
Some lenders or other stakeholders may also request QoE, so waiting until late diligence can create a timing squeeze.
If you skip or delay QoE, you increase the risk of negotiating on the seller’s numbers instead of a tested baseline.
Before QoE starts, ask the seller for:
Monthly financials and the general ledger
Bank statements and reconciliations
Add-back schedule with support
AR and AP aging and inventory detail (if applicable)
Misconceptions on QoE for SMB Deals
“Stable revenue means low risk.” Stability can still hide weak add-backs, cash mismatch, or working capital strain.
“If it is not lender-required, it’s optional.” Lender expectations vary, but QoE can still help protect your underwriting and valuation assumptions.
Quick Decision Rules
Do QoE: When add-backs are heavy, cash is unclear, or working capital is tight.
Consider a lighter scope first: When the model is simple, and support is clean, but still validates cash.
Request the core documents early and make the scope match the assumptions on which your valuation and financing depend.
Who Provides Quality of Earnings Services?
QoE services are typically provided by transaction advisory teams within accounting firms and by specialized due diligence providers. For SMB buyers, the right choice is the provider who works in your deal size, can validate earnings with support, and delivers a report you can use in the deal.
Who typically provides QoE:
Accounting firms with transaction advisory teams
Independent due diligence and transaction advisory specialists
Boutique providers focused on SMB acquisitions
How to Choose a QoE Provider for an SMB Deal
Deal-size fit: Ask how often they work in your size range.
Deliverable clarity: Require a sample and confirm you will get a clear earnings analysis and a risk summary.
Cash validation: Ask how they tie back to bank activity when cash does not track revenue.
Working capital: Ask whether they quantify working capital needs in deal terms.
Communication: Ask who you will work with day to day and how findings will be explained.
What good looks like is simple: scope in writing and a sample deliverable where adjustments tie back to support.
Misconceptions on Choosing a QoE Provider
“Any accountant can do QoE.” QoE is transaction diligence and requires deal context, not just clean books.
“The deliverable does not matter.” If you cannot use the output to negotiate or underwrite, the work missed its purpose.
