Quick answer: QoE stands for Quality of Earnings. A QoE analysis checks whether a company's reported earnings, usually adjusted EBITDA, are real, recurring and supported by the records, by tying revenue to the bank, testing every add-back and setting a normal level of working capital. Buyers use it to decide what the business is worth before they close. On smaller deals a lighter scope, often called QoE lite or financial due diligence, covers the most important checks for less.
If you're buying a business, "Quality of Earnings" is the phrase you'll hear most between signing the LOI and closing. A Quality of Earnings (QoE) analysis answers the one question the asking price depends on: how much does this business really earn, and is that number durable? The seller hands you an "adjusted EBITDA." A QoE pressure-tests it.
This is a plain-English guide to what a QoE report is, what it actually examines, how it differs from an audit, and what it costs, written for search funds, independent sponsors, and self-funded buyers rather than for accountants.
What a Quality of Earnings report actually is
A QoE report is an independent analysis of a company's normalized, sustainable earnings, usually built around Adjusted EBITDA. It rebuilds the earnings number from the underlying records, then strips out anything that isn't a recurring part of the business so you can see the run-rate a new owner would inherit.
It is the difference between "the seller says the business makes $1.2M" and "the business makes $980k of defensible, recurring earnings once you remove the owner's add-backs that don't hold up." That gap is what you negotiate on.
QoE vs. an audit, they are not the same thing
This is the most common point of confusion, so it's worth being precise:
- An audit asks: do these financial statements comply with accounting standards (GAAP) at a point in time? It's backward-looking and gives an opinion on the statements as presented.
- A QoE asks: are these earnings real, normalized, and sustainable for a buyer going forward? It's economic, not compliance-driven, and it deliberately adjusts the reported numbers.
A business can have clean audited statements and still have low-quality earnings (e.g. profit propped up by a one-time contract). Most small businesses you'll look at aren't audited at all, which is exactly why buy-side QoE exists.
| Audit | Buy-side QoE | Financial due diligence (lite) | |
|---|---|---|---|
| Question it answers | Do the statements comply with GAAP? | Are the earnings real, normalized, and sustainable for a buyer? | A focused subset of a QoE, scoped to a smaller deal |
| Orientation | Backward-looking, compliance | Forward-looking, economic | Forward-looking, right-sized |
| Typical cost | Varies; often not done on small deals | $15,000 to $50,000+ | Less than a full QoE |
| Best for | A regulatory or financing requirement | The deal you're serious about | Smaller deals where a full QoE is overkill |
What a QoE analysis examines
A good QoE goes line by line. The core areas:
- Proof of cash, reconciling reported revenue to actual bank deposits. The fastest way to catch overstated or phantom revenue.
- Normalized / Adjusted EBITDA, the headline output: reported earnings adjusted for non-recurring, non-operating, and owner-specific items.
- Add-back scrutiny, this is where deals are won and lost. Legitimate add-backs (a one-time legal settlement, above-market owner salary, personal expenses run through the business) are accepted; aggressive ones (recurring costs dressed up as "one-time," optimistic "run-rate" revenue that never happened) are rejected.
- Revenue quality, recurring vs. one-time revenue, customer concentration, and whether margins are stable or quietly eroding.
- Net working capital, establishing the normal level of working capital the business needs to operate, which becomes the peg in the purchase agreement so you aren't surprised at close.
- One-time and related-party items, non-arm's-length rent, family on payroll, related-party sales, all normalized to market terms.
Common QoE adjustments at a glance
| Adjustment | What it does | Usually accepted? |
|---|---|---|
| Above-market owner salary | Normalizes pay to a market replacement rate | Yes |
| Personal / discretionary expenses | Removes owner perks run through the business | Yes, with proof |
| One-time legal or settlement costs | Strips a genuine non-recurring cost | Yes, if truly one-time |
| Related-party rent or sales | Restates to arm's-length market terms | Yes |
| "Run-rate" revenue not yet earned | Adds revenue that has not happened | No |
| Recurring costs labeled "one-time" | Hides ongoing expenses as add-backs | No |
Buy-side vs. sell-side QoE
There are two kinds, and they serve different masters:
- Sell-side QoE is commissioned by the seller to present the business well and pre-empt buyer questions. Useful, but read it knowing who paid for it.
- Buy-side QoE is yours. It exists to protect you, and it's the one that supports your financing and your final price. Even when a sell-side report exists, serious buyers run their own confirmatory work.
What QoE typically costs and how long it takes
For a lower-middle-market or small-business deal, a focused buy-side QoE commonly runs $15,000–$50,000+ and takes 2–4 weeks, depending on the quality of the seller's records and the complexity of the business. On smaller deals, buyers often scope a lighter "financial due diligence" engagement rather than a full QoE, the point is to right-size the cost to the deal, not to skip the work.
QoE lite: a lighter scope for smaller deals
"QoE lite" is not a formal standard; it is the name buyers and advisers use for a narrower engagement on a smaller deal. It usually keeps the checks that move the price, and drops the rest:
- Usually kept: proof of cash (revenue tied to bank deposits), the add-back review, and a first view of normal working capital.
- Often reduced or dropped: month-by-month trend analysis, detailed customer and product cuts, and a full written report.
A lighter scope is a sensible trade on a small business with simple books. It is a poor trade when revenue is concentrated in a few customers, when cash and reported revenue do not match, or when the lender financing the deal asks for a full report. Agree the scope in writing, so you know which checks were not done.
Quality of earnings for a small business acquisition
Small businesses raise the same questions with fewer records to answer them. A few things are different:
- The books are often cash-basis or tax-driven, prepared to minimise tax rather than to show earnings, so more adjustments are needed before the numbers mean anything.
- The owner is often the business. Their salary, their family on payroll, their car and their relationships with key customers all need normalising, and some of that value may leave with them.
- Add-backs carry more of the price. On a small deal a few personal expenses can be a large share of adjusted EBITDA, so each one needs a document behind it.
- The lender may set the bar. Banks financing an acquisition often ask for an independent review of earnings, so check what yours requires before you choose the scope.
How to prepare for a QoE
The faster the provider gets clean documents, the less the engagement costs. Ask the seller for these early:
- Monthly profit and loss statements and balance sheets for the last two to three years, plus year to date.
- Tax returns for the same years.
- Bank statements for every account, to tie revenue to cash.
- The seller's list of add-backs, with a document for each one.
- Revenue by customer, to see concentration and churn.
- Payroll records, including any family members and owner pay.
- Accounts receivable and payable ageing, and inventory records if the business holds stock.
- Major contracts, leases and any debt agreements.
Outsourcing a QoE: who does it and how to choose
Buy-side QoE work is usually done by accounting firms with a transaction advisory team, or by independent specialists who focus on smaller deals. When you compare providers, ask:
- Have they done QoE work on businesses of this size and in this industry?
- What exactly is in scope: proof of cash, add-backs, working capital, a written report, a call to walk through findings?
- Who does the work day to day, and who signs off on it?
- Will the lender financing the deal accept their report?
- What do they need from you and the seller, and by when?
Doing your own first pass on the documents before you engage them shortens their work and sharpens the questions you pay them to answer.
Red flags a QoE surfaces
- Reported revenue that won't reconcile to bank deposits.
- Add-backs that quietly inflate EBITDA beyond what's defensible.
- "Recurring" revenue that turns out to be a one-time or non-renewing contract.
- Margins drifting down while the headline EBITDA holds up.
- Working capital being managed down right before a sale to flatter cash.
Where the document work fits, and how to compress it
A QoE is document-heavy: financials, tax returns, bank statements, the Confidential Information Memorandum, and a data room of contracts, all cross-checked against each other. Your accountant does the judgment; a lot of the grind is finding and reconciling the source documents.
That groundwork is exactly what Deal OS is built to accelerate. It reads the documents in a deal workspace and runs a quality-of-earnings first pass: it ties the same EBITDA figure out across the CIM, the financials, and the tax return, flags every discrepancy, and scrutinizes each add-back for whether it survives a sale, with every figure quoted from your own files and verified before you see it, plus contradiction and missing-information audits across the data room. It doesn't replace your QoE provider or your judgment; it gets you and your advisors to a defensible number, and the questions that matter, faster, so the paid engagement starts from an organized, already-flagged position instead of a cold data room. It's how searchers and sponsors review more deals without hiring an analyst, and it pairs naturally with the broader due diligence checklist. If you'd rather build reconciliation that fits your own books than adopt a fixed tool, that is a natural brief for a fractional AI engineer, and founders who close deals through several holding companies often fold this recurring document work into AI automation across their entities. You can try the first pass on a deal that looks like yours in the interactive sandbox, no login.
Frequently asked questions
What is a Quality of Earnings report? An independent analysis of a company's normalized, sustainable earnings, usually Adjusted EBITDA, that rebuilds the earnings number from source records and strips out non-recurring, non-operating, and owner-specific items so a buyer can see the true run-rate they'd inherit.
What is the difference between a Quality of Earnings report and an audit? An audit gives an opinion on whether financial statements comply with accounting standards at a point in time; it's backward-looking. A QoE asks whether earnings are real, normalized, and sustainable going forward, and deliberately adjusts the reported numbers. A business can have clean audited statements and still have low-quality earnings.
How much does a Quality of Earnings report cost? For a small-business or lower-middle-market acquisition, a focused buy-side QoE typically costs $15,000–$50,000+ and takes 2–4 weeks, depending on record quality and deal complexity. Smaller deals often use a lighter financial-due-diligence scope instead of a full QoE.
Is a Quality of Earnings worth it for a small deal? For anything but the smallest deals, yes. A focused QoE or financial-due-diligence review costs a fraction of what you'd lose by overpaying for earnings that aren't real, or by inheriting a working-capital surprise at close. Right-size the scope: a lighter financial-due-diligence engagement on smaller deals, a full QoE on the ones you're serious about.
Can software do a Quality of Earnings? Software can do the QoE first pass: it ties EBITDA out across the CIM, the financials, and the tax return, flags discrepancies, and scrutinizes the add-backs, so you reach a defensible number before you commission a formal engagement. It does not produce the signed opinion your lender and reps-and-warranties rely on, that still comes from your QoE provider, who now starts from an organized, already-flagged position instead of a cold data room.
What are add-backs in a Quality of Earnings analysis? Add-backs are adjustments to reported earnings for items a new owner will not incur, such as one-time legal costs, above-market owner salary, or personal expenses run through the business. Legitimate add-backs raise normalized EBITDA; aggressive or unsupportable add-backs are what a buy-side QoE is meant to reject.
Do I need a Quality of Earnings report for a small acquisition? For anything beyond the smallest deals, yes, at minimum a confirmatory financial-due-diligence review. The cost is small relative to overpaying for earnings that are not real. Right-size the scope to the size of the deal.
What does QoE mean? QoE stands for Quality of Earnings: an analysis of whether a company's reported earnings, usually adjusted EBITDA, are real, recurring and supported by the records. Buyers use it before closing to confirm what they are paying for.
What is QoE lite? An informal name for a narrower quality of earnings engagement on a smaller deal. It usually keeps proof of cash, the add-back review and a first view of working capital, and drops detailed trend analysis and the full report. Agree the scope in writing so you know what was not checked.
