Quality of Earnings: The Report That Reprices Your Deal — and What Actually Survives Buyer Scrutiny (2026)
I'm Sean Yu, co-founder of Peony. Today 6,800+ customers run their deals on our platform, which holds $26.3B in client assets, and the pattern I see on nearly every sale is the same: the letter of intent names a price, and then a quality of earnings report decides how much of it actually reaches the seller's bank account. Sellers do not lose in the QoE because their earnings are bad. They lose because their add-backs are asserted instead of evidenced.
Quick answer: A quality of earnings (QoE) report is not an exam you pass — it is the document that sets the number your deal actually prices on. It tests whether historical earnings are sustainable and normalizes EBITDA to a defensible going-forward figure, and that figure times the multiple is your headline price. It is not an audit: per Warren Averett, "a quality of earnings analysis is not an audit and, therefore, no opinion is given." Every add-back is a claim; diligence is the trial; the data room is the evidence locker. The seller who can prove each number keeps it; the seller who cannot, negotiates it away.

Why I wrote this
I run Peony, a data room company, and I will be straight about where we fit: Peony organizes, permissions, and evidences the documents a QoE runs on — it does not perform your QoE, calculate your working capital peg, or replace your accountants. This post is for the owner whose banker just said "buyers will run a QoE, you should get one first," and who is now staring at a $30–60K quote wondering whether it is worth it, which add-backs will survive, and whether it is safe to hand three years of monthly financials to a buyer's accountants at all.
I wrote it because the internet is full of QoE content that invents statistics — one number in particular that I debunk explicitly below. What follows is the honest version: what a QoE is, what the team examines, which add-backs survive, what it costs and how long it takes, and how a governed room turns your documents into a re-trade defense. It sits alongside our broader diligence coverage — the what-is-due-diligence hub maps all seven workstreams, and this post goes deep on the financial one that sets your price.
What is a quality of earnings report — and how is it different from an audit and reviewed statements?
A quality of earnings report is a transaction-focused financial analysis that tests whether a company's historical earnings are sustainable and normalizes EBITDA to what the business would earn under new ownership — stripping out one-time items, owner-specific expenses, and non-operating noise to reach a defensible run-rate number. That normalized figure is what the deal multiple gets applied to, which is why the QoE is the single most consequential document in financial due diligence. It is analysis, not attestation.
The distinction that trips up first-time sellers is the difference between a QoE, an audit, and reviewed statements — they answer three different questions. An audit forms an opinion on whether financial statements are fairly presented under accounting standards. A QoE carries no such opinion at all: Warren Averett states it directly — "a quality of earnings analysis is not an audit and, therefore, no opinion is given." Grant Thornton draws the same line: a QoE "is transaction-focused. It looks at historical performance through an economic lens, with selective forward-looking normalisations where appropriate. Rather than issuing an audit opinion, it produces an adjusted view of earnings sustainability, which is commonly used as an input for valuation, negotiations and deal structuring."
Reviewed statements sit in between — a review gives limited assurance that financials conform to accounting standards, but like an audit it is backward-looking and does not normalize EBITDA or test earnings sustainability. So having reviewed (or even audited) statements does not remove the need for a QoE; it just makes the QoE faster and cheaper because the books are cleaner going in. Put simply: an audit or review tells you the books were kept correctly; a QoE tells you what the business actually earns once you normalize for owner quirks and one-time noise. This is the archetypal hard due diligence — verifiable numbers, tested line by line. A company can have a spotless audit and still lose a million dollars of price in a QoE, because the QoE asks the question the multiple actually prices on.
Do you need a sell-side QoE before going to market?
If you are the seller, you do not strictly need your own QoE — but commissioning one before you go to market is the single most useful move a seller can make, because the buyer will run one regardless, and whoever finds the problems first controls the narrative. A buy-side QoE is run by the buyer's deal team to evaluate a target and becomes the buyer's leverage. A sell-side QoE flips the timing: you commission it, find your own issues, and either fix them or prepare to defend them before a buyer's accountant ever raises them.
The rationale is well put by Haynie & Company on three fronts. You find issues early — the proactive approach "allows potential issues to be identified and addressed early, rather than surfaced by buyers under compressed diligence timelines." You gain credibility — "a third-party QoE adds objectivity and provides a defensible framework for buyers, lenders, and advisors during diligence." And you speed the process — a well-prepared QoE "often leads to fewer follow-up questions, faster diligence cycles, and smoother negotiations."
A note on trust, because sellers ask constantly whether a buyer trusts a seller-paid QoE. It is not a rubber stamp — reputable firms apply the same rigor whichever side pays, and the buyer will still run a confirmatory buy-side QoE on larger deals. What it buys you is not blind faith; it is a defensible framework and a head start on the problems. On the Big-Four-versus-regional question, the choice scales with deal size and complexity, not brand alone — a clean single-entity target under $50M rarely needs a Big Four engagement. For the full pre-market program, see our sell-side due diligence playbook, and for the buyer's-eye view, how to acquire a company and private equity due diligence.
What does the QoE team examine, what documents do they ask for, and what is a proof of cash?
The QoE team examines the quality and sustainability of your earnings — not just whether the numbers add up, but whether they will repeat under new ownership and whether they show up in cash. That work begins with a request list longer and more granular than most first-time sellers expect, and the single biggest surprise is that they want monthly financials for three-plus years, not annual statements. Monthly data is how they test seasonality, spot revenue pulled forward, and catch one-time items that annual figures smooth over.
The standard request list runs roughly like this:
- Income statement — monthly P&Ls for 3+ years, revenue by product or service line.
- Balance sheet — monthly balance sheets for 3+ years, plus the trial balance.
- General ledger — full GL / transaction-level detail.
- Revenue detail — revenue by customer, contract and subscription schedules, deferred revenue. (Your most confidential data — customer concentration exposed line by line.)
- Receivables and payables — AR aging, AP aging, bad-debt history.
- Inventory — detail, obsolescence reserves, costing method.
- Fixed assets — the fixed-asset register, depreciation schedule, capex history.
- Payroll and headcount — payroll detail, headcount by function, bonus and commission plans. (Also high-sensitivity compensation data.)
- Debt — the debt schedule, loan agreements, capital-lease detail.
- Tax — federal and state returns for 3+ years.
- Add-back support — documentation for every proposed EBITDA adjustment.
One test inside that work deserves its own explanation because sellers ask about it by name: the proof of cash. Per Lutz, "a proof of cash reconciles reported net revenues and expenses to cash inflows and outflows per supporting documentation like bank statements." In plain terms, it checks that the earnings on your income statement actually landed in the bank rather than in accounting entries. It is one of the most powerful tests the team runs, because cash is hard to fake: aggressive revenue recognition or misclassified expenses tend to break the reconciliation. Clean, complete bank statements and a tidy GL make it fast and uneventful; gaps turn it into follow-up questions and delay.
Two categories on that request list carry real confidentiality weight — customer-level revenue and payroll — so they belong in watermarked, access-scoped folders the QoE team can reach but not everyone can. The fastest engagements are the ones where the seller assembled these into a request-list-driven room before the team started, so week one is analysis, not a document hunt. For the full request-list structure, see our investment due diligence checklist.
Which add-backs survive buyer scrutiny? The evidence table
Add-backs are the adjustments that turn reported EBITDA into adjusted EBITDA. They are legitimate — a business whose owner pays himself below market, or runs a personal vehicle through the company, does earn more than the reported number suggests — but they are also where sellers get greedy, and testing each one is exactly what the QoE team is paid to do. Doeren Mayhew lists the typical EBITDA adjustments as owner salaries and bonuses ("family-owned businesses often pay owners and family members' higher salaries or bonuses"), other owner personal expenses and perks ("company cars, club memberships, entertainment and more"), and one-time non-recurring expenses.
Here is the mental model that matters more than any list: every add-back is a claim, and diligence is the trial. The claim survives only if the evidence matches it. The table below takes the five adjustments I see on almost every owner-operated business and shows, for each, the claim, what the buyer's accountants test, the evidence that survives, and what kills it.
| The claim | What the buyer's accountants test | Evidence that survives | What kills it |
|---|---|---|---|
| Owner salary adjusted to market | Whether your reported salary is genuinely below the market rate for the role — and whether a replacement manager is needed | A third-party compensation study or benchmark showing the market rate for the role; an org chart proving the work is covered post-close | An adjustment with no benchmark, or "adding back" all owner comp when the business still needs someone to do the job (that requires a negative adjustment) |
| Family members on payroll | Whether family salaries are above market, whether the roles are real, and whether the cost leaves at close | Market-rate comparison for each role; documentation that the family member departs at close, or that the role is filled at market rate | Family members staying on post-close, real roles priced at market, or no proof the salary was above market to begin with |
| Personal vehicle & expenses | Whether the expense is truly personal and whether it genuinely stops under new ownership | The vehicle title, the expense detail, and evidence the cost ends at close (perks like "company cars, club memberships, entertainment" per Doeren Mayhew) | A perk that continues under new ownership, or personal spend commingled with a genuine business expense with no way to separate them |
| One-time legal settlement | Whether the event was genuinely a one-time occurrence and not a recurring category of cost | The settlement agreement and supporting correspondence proving a discrete, non-repeating event | A "settlement" from a business that is sued regularly — a recurring category dressed up as a single event |
| "One-time" items that recur | Whether an item labeled non-recurring appears across multiple years | A clean, documented one-off that shows up once and never again | The same "one-time" cost appearing in all three years of monthly financials — the fastest add-back to reverse |

The pattern across every row is identical: assertion loses, evidence wins. The buyer's test reduces to one question — will this cost really disappear under new ownership, and can you prove it? And reversals are expensive in a way that is easy to underestimate, because EBITDA is multiplied: at a mid-single-digit multiple, a reversed add-back moves the price by several times its own size. That is the whole reason a sell-side QoE pays for itself — it surfaces the weak add-backs while you still have time to build the evidence or drop the claim, rather than having them reversed under a buyer's compressed timeline. For the patterns that draw the most fire, our operational due diligence guide covers the process-side red flags that often accompany financial ones.
What share of add-backs gets rejected in diligence?
Here is the honest beat, and it matters because a competitor's QoE content is built on a number that does not exist: there is no published dataset supporting any "percentage of add-backs rejected" figure, and anyone quoting one is guessing. You will see content citing specific rejection rates — figures like "10-30% of add-backs get rejected in diligence." I went looking for a credible primary source behind those numbers and could not find one. The firm pages that actually discuss add-backs do not publish a rejection rate; the percentages that circulate trace back to unsourced content that repeats itself across the web until it looks authoritative. Treat any quoted percentage as marketing.
This is not hedging for its own sake. Planning around a rejection rate is actively harmful, because it frames the outcome as a lottery when the outcome is not random at all — it is a direct function of documentation. A fully evidenced add-back does not get reversed; an unsupported one does. The variable is not some external percentage you are subject to; it is the quality of the evidence you bring, which you control completely.
What is true is the mechanic, not a rate. An unsupported add-back gets reversed dollar-for-dollar, and because adjusted EBITDA is multiplied by the deal multiple, the damage is leveraged: at a 6.0x multiple, a $200K add-back the team cannot verify is $1.2M of enterprise value gone (illustrative round numbers, not a sourced deal statistic). So the productive question is never "what percentage will they reject?" It is "which of my add-backs is the one I cannot prove?" — because that is the one that moves your price. Document every add-back, and the rejection rate becomes irrelevant to you.
How does the re-trade work — and how does documentation prevent it?
Every seller's nightmare has a name: the re-trade. A re-trade is the buyer renegotiating the price down after the LOI — typically during diligence — by raising an issue and demanding a price adjustment. The LOI price is not binding; the QoE window is precisely where the buyer can lower it, and the levers they pull are the ones this post has already walked through: a reversed add-back, a working capital shortfall against the agreed peg, an undisclosed debt-like item.
A caution first, consistent with the honesty beat above: this is another place where content invents statistics. You will see specific re-trade percentages quoted — "X% of deals get re-traded," "sellers without a sell-side QoE lose Y%." Those figures do not trace to any credible primary source either, so I am not going to repeat them. The question is not whether your price will be tested — in any serious process it will be — but whether it survives the test.
And the defense is not negotiation theater; it is documentation. A re-trade needs a hook: an add-back the QoE team cannot verify, a peg the seller cannot support, a liability the seller did not disclose. Take away the hooks and you take away the leverage — which comes down to four documentation tasks: run a sell-side QoE before you go to market; build an auditable EBITDA bridge from reported to adjusted, with support behind every add-back; peg working capital on real trailing-twelve-month data you can reconcile to the closing balance sheet; and map debt-like items early so you argue classification with evidence rather than concede at closing.
Every one of those is a documentation task — entirely within your control, which is the most reassuring thing I can tell a nervous seller. The re-trade preys on gaps; close the gaps and there is nothing to pry. For how the QoE feeds the working capital peg and the purchase agreement, see our due diligence timeline, which maps where the QoE sits on the deal's critical path.
How much does a quality of earnings cost, and how long does it take?
Here are the canon numbers, and I am deliberately keeping this section a summary — the full line-item build lives in our due diligence cost breakdown, which is the canonical cost page for this cluster.
Cost. A quality of earnings report costs $10k–$30k for simple businesses to $60k–$100k+ for larger, multi-entity companies, and it is typically the largest single line item in financial due diligence. Broken out by deal size, a QoE runs roughly $10k–$35k on small deals, $25k–$60k on mid-sized deals, and $60k–$100k+ on large deals. For context, total external due diligence across all workstreams typically runs 0.2%–4% of deal value, and a well-organized data room can cut adviser time by 25–35% — which makes data quality your single most controllable cost lever. So is a $30–60K sell-side QoE worth it? For most owner-operated businesses going to market, yes: a single reversed add-back at a mid-single-digit multiple routinely costs more than the entire QoE fee.
Timeline. A standard mid-market QoE runs 3–6 weeks depending on data quality and management responsiveness, per Anders and DueDilio; complex or multi-location deals run 6–8 weeks, the broader range is often quoted at 4–8 weeks including management review, and Big Four "compressed," AI-tooled QoE can run as low as 5 days on clean targets. But QoE turnaround is not the same as deal timeline — the QoE sits on the critical path, because it must finalize before the working capital peg can be set, and the peg drives the purchase agreement and everything downstream. Across 334 M&A transactions on the Peony platform, blended time-to-close stretched to about 8.6 months in Q2 2026, so the QoE is a few weeks inside a much longer arc — and the biggest lever on its speed, again, is data quality.
Who pays follows who commissions: in classic buy-side M&A the buyer pays for their own advisors, including their QoE; in sell-side or auction processes the seller commissions the QoE and shares it with bidders, front-loading some of the cost — and on larger deals you often see both.
Where does the data room fit during a QoE? The evidence locker
Everything above turns on one anxious question sellers ask me directly: is it safe to hand three years of monthly financials and customer-level data to a buyer's accountants? The answer is yes — if you control how you hand it over. The exposure is real: customer-level revenue reveals your concentration line by line, and payroll exposes what everyone earns. But the answer is a governed data room, not withholding data (which just slows the QoE and signals you have something to hide). If every add-back is a claim and diligence is the trial, the data room is the evidence locker — where your proof is organized, permissioned, and, crucially, logged.
Here is what a purpose-built room does that a shared drive cannot, mapped to the QoE:
- Staged, scoped access per reviewer. Your QoE team needs financials, revenue detail, and add-back support; your lender needs financials, tax, and the debt schedule; your counsel needs contracts. One pile, many scoped views — the QoE associate never sees folders outside their scope, and you never re-send anything.
- Watermarked monthlies. Customer-level revenue and payroll are your most confidential files; dynamic watermarks stamp each viewer's identity onto every page, so if a monthly P&L leaks, it carries a forensic trail back to whoever exported it.
- Granular permissions, not link-sharing. The QoE team, the lender's analysts, and co-investors each get their own scoped access — nobody forwards a link that opens the whole room.
- The audit log as re-trade defense. The room records which party viewed which document and when — proof of what was disclosed, which is precisely the evidence that defuses a late-stage "we didn't know about this" re-trade attempt. Data room analytics also tell you which buyers are serious — the ones reading deeply versus the ones skimming.
On pricing, the Peony canon plainly: four tiers — Free at $0 (2 GB of storage), Business at $30 per admin per month, Data Room at $52 per admin per month (unlimited rooms and storage), and Deal Team at $64 per admin per month, minimum four admins (adding Advanced Redaction, Advanced Q&A, and API access). That shape matters for a QoE, because your QoE associates, your lender's analysts, and your co-investors are recipients — they never count against your admin bill. See the full breakdown on our pricing page. Today 6,800+ customers run their deals on Peony, the platform holds $26.3B in client assets, and it is SOC 2 Type II certified with AES-256 encryption at rest and TLS 1.3 in transit.
The honest boundary — and I want to be unambiguous about it. A data room cannot make weak evidence strong. If an add-back has no support, no amount of folder structure or watermarking will save it; the QoE team will reverse it anyway. The QoE is the accountants' work product — Peony does not perform the analysis, normalize your EBITDA, or classify your debt-like items. What the room does is make every number you can prove genuinely provable: organized, scoped, watermarked, and evidenced with a full audit trail — the one part of the QoE the seller controls end to end. For how the room orchestrates a multi-party deal, see our M&A data room guide and the M&A solutions overview.
Frequently asked questions
My banker says buyers will run a QoE — do I need to commission my own first?
You do not strictly need your own, but a sell-side QoE is the single best thing a seller can do before going to market. The buyer will run one regardless, and whoever finds the problems first controls the narrative. Per Haynie & Company, commissioning early "allows potential issues to be identified and addressed early, rather than surfaced by buyers under compressed diligence timelines," and a third-party QoE "adds objectivity and provides a defensible framework for buyers, lenders, and advisors during diligence." The payoff, per Haynie, is "fewer follow-up questions, faster diligence cycles, and smoother negotiations." It costs money, but a reversed add-back you did not see coming costs far more. Think of it as finding your own problems while you still control the story, not as buying a clean bill of health.
Is a quality of earnings report the same as an audit?
No. They answer different questions. An audit forms an opinion on whether financial statements are fairly presented under accounting standards; a QoE tests whether earnings are sustainable and normalizes EBITDA for what the business earns going forward. Warren Averett states it directly: "a quality of earnings analysis is not an audit and, therefore, no opinion is given." Grant Thornton frames the contrast the same way — a QoE is "transaction-focused" and "rather than issuing an audit opinion, it produces an adjusted view of earnings sustainability, which is commonly used as an input for valuation, negotiations and deal structuring." So an audit tells you the books were kept correctly; a QoE tells you what the business actually earns once you strip out owner quirks and one-time noise. A company can have a clean audit and still lose price in a QoE.
I have reviewed financial statements — isn't that enough to sell?
Reviewed statements help, but they are not a QoE and they will not carry your price by themselves. A review provides limited assurance that financials conform to accounting standards; it does not normalize EBITDA, test the sustainability of earnings, or reconcile reported results to cash. The buyer's team runs a QoE precisely because reviewed or even audited statements are backward-looking and do not answer the question the multiple gets applied to: what does this business earn on a going-forward basis under new ownership? Reviewed statements are a good starting input — cleaner books mean a faster, cheaper QoE — but the adjustments that move the price live in the QoE, not the review. If your books carry owner add-backs, family salaries, or one-time items, those need evidence a review was never designed to provide.
Which add-backs actually survive buyer scrutiny?
The ones that are documented and genuinely non-recurring. Doeren Mayhew lists the typical EBITDA adjustment categories as owner salaries and bonuses, other owner personal expenses and perks ("company cars, club memberships, entertainment"), and one-time non-recurring expenses. Add-backs survive when the evidence matches the claim: a below-market owner salary survives with a compensation study showing the market rate; a personal vehicle survives with the title and the removal of the expense post-close; a legal settlement survives with the agreement proving it was a one-time event. What kills an add-back is the opposite — a "one-time" cost that shows up in all three years, a perk that continues under new ownership, or an adjustment asserted with no supporting document. The test buyers apply is simple: will this cost really disappear, and can you prove it? Assertion loses; evidence wins.
What share of add-backs gets rejected in diligence?
There is no reliable number, and anyone quoting one is guessing. You will find content citing a specific percentage of add-backs rejected in diligence — figures like "10-30%." I looked for a credible source behind those numbers and could not find one; the firm pages that discuss add-backs do not publish a rejection rate, and the percentages that circulate trace back to unsourced content. Treat any quoted percentage as marketing. What is true is the mechanic, not a rate: an unsupported add-back gets reversed dollar-for-dollar, and because EBITDA is multiplied by the deal multiple, each reversal moves the price by several times its own size. So do not plan around a benchmark rejection rate — plan around documentation. The outcome depends entirely on the quality of your evidence, which is the one variable you control.
How do I stop the buyer re-trading the price after diligence?
A re-trade is the buyer renegotiating the price down after the LOI, typically during diligence, by raising an issue and demanding an adjustment. The LOI price is not binding, so the defense is not negotiation theater — it is documentation. A re-trade needs a hook: an add-back the QoE team cannot verify, a working capital shortfall, an undisclosed debt-like item. Take away the hooks and you take away the leverage. That means running a sell-side QoE before you go to market, building an auditable EBITDA bridge with support for every add-back, and pegging working capital on real trailing-twelve-month data. The seller who can prove each number keeps it; the seller who cannot, negotiates it away. Every item on that list is a documentation task, which is the most reassuring thing I can tell a nervous seller — it is entirely within your control.
How much does a quality of earnings cost, and how long does it take?
A QoE costs $10k-$30k for simple businesses and $60k-$100k+ for larger, multi-entity companies, and it is typically the largest single line item in financial due diligence. By deal size, a QoE runs roughly $10k-$35k on small deals, $25k-$60k on mid-sized deals, and $60k-$100k+ on large deals. On timing, a standard mid-market QoE runs 3-6 weeks depending on data quality and management responsiveness; complex or multi-location deals run 6-8 weeks, and Big Four AI-tooled QoE can drop as low as 5 days on clean targets. Who pays follows who commissions: buyers pay for buy-side, sellers pay for sell-side and share it with bidders. The single biggest lever on both cost and speed is data quality — the cleaner your room on day one, the cheaper and faster the QoE. Our cost breakdown carries the full line-item detail.
What documents will the QoE team ask for?
More than most first-time sellers expect, and monthly rather than annual. The QoE team asks for three-plus years of monthly financials — monthly data is how they test seasonality and catch one-time items annual figures smooth over. Expect requests for monthly P&Ls and balance sheets, the trial balance and general ledger detail, AR and AP agings, a revenue-by-customer file, the deferred revenue schedule, inventory detail, the fixed-asset register, payroll and headcount detail, the debt schedule, and federal and state tax returns — plus documentation for every proposed add-back. Several of these are sensitive: customer-level revenue and payroll expose your most confidential data, so they belong in access-controlled, watermarked folders, not an email thread. The fastest engagements are the ones where the seller built these into a request-list-driven room before the QoE team started, so day one is analysis, not a scavenger hunt.
Is it safe to hand three years of monthly financials and customer data to a buyer's accountants?
Yes, if you control how you hand it over. The exposure is real — customer-level revenue reveals your concentration line by line, and payroll exposes compensation — but the answer is a governed data room, not withholding data. In a purpose-built room you give the QoE team scoped access to only the folders they need, watermark every sensitive page with the viewer's identity so a leak leaves a forensic trail, and keep an audit log of exactly what was disclosed and when. That audit log is also your re-trade defense: proof of what the buyer saw. Peony is SOC 2 Type II certified with AES-256 encryption at rest and TLS 1.3 in transit. The honest limit: a data room governs and evidences the exchange — it cannot make weak evidence strong. The QoE itself is the accountants' work product.
What is a proof of cash?
A proof of cash is one of the core tests inside a QoE. Per Lutz, "a proof of cash reconciles reported net revenues and expenses to cash inflows and outflows per supporting documentation like bank statements." In plain terms, it checks that the earnings on the income statement actually show up in the bank — that reported revenue and expenses tie back to real cash activity rather than accounting entries. It is one of the most effective tests the QoE team runs, because it is hard to fake cash: aggressive revenue recognition, channel stuffing, or misclassified expenses tend to break the reconciliation. For a seller, the takeaway is practical — clean, complete bank statements and a tidy general ledger make the proof of cash fast and uneventful, while gaps in either turn it into a source of follow-up questions and delay.
