Quality of Earnings: What a QoE Report Checks Before a Sale

By the Korven team · Published

The short answer

Quality of earnings (QoE) is a financial due diligence analysis that tests whether a company's reported EBITDA is real, recurring and supported by its ledger and bank records. A QoE report rebuilds EBITDA from the general ledger, removes one-time and owner items, tests revenue quality and customer concentration, sets a normal level of working capital and lists the debt-like items a buyer would inherit. It is not an audit: it gives no opinion on the financial statements. Buyers use it to set the price; sellers use it to defend theirs.

What is a quality of earnings report?

A quality of earnings report is the written result of that analysis. It starts from the EBITDA management presents, usually called adjusted EBITDA, and walks it line by line to the EBITDA the evidence supports. The gap between the two numbers is the point of the exercise. Many private companies are valued as a multiple of EBITDA, so every dollar of earnings that does not hold up can cost the seller that dollar times the multiple.

EBITDA is not a US GAAP measure, and adjusted EBITDA is whatever the person presenting it says it is. The SEC's staff guidance for public companies says a measure calculated differently from plain EBITDA should carry its own title, such as "Adjusted EBITDA", and that leaving out normal, recurring cash operating expenses can make a measure misleading (SEC, Non-GAAP Financial Measures). A private sale is not bound by those rules, but a buyer's diligence team applies the same logic to every add-back on your deal sheet.

How is a QoE different from an audit?

An audit answers whether the financial statements are fairly presented. The SEC describes the auditor's product as a written report containing an opinion on whether the statements are fairly stated (SEC, All About Auditors). A QoE answers a different question: what does this business really earn on a normal, repeatable basis, and what will a new owner inherit on the balance sheet?

A QoE is usually performed as a consulting engagement. The AICPA's Journal of Accountancy describes consulting services under the CS section 100 standard as nonattest services in which no opinion, conclusion or assurance is provided (Journal of Accountancy). In practice, an audited company can still have weak quality of earnings, and a company with clean QoE findings has not been audited.

What does a quality of earnings report check?

Scope varies with the deal, but a complete review covers seven areas. Each one ends in a number the buyer will use in the price or the purchase agreement.

AreaWhat the reviewer testsWhy a buyer cares
EBITDA adjustmentsEach adjustment traced to evidence, and classed as truly one-time, recurring or run-rateNormalized EBITDA is the base the multiple is applied to
Owner add-backsOwner pay against the cost of a replacement manager, personal spending, related-party rentAn add-back is only valid if the cost really leaves with the owner
Revenue qualityRevenue in the right period, recurring versus one-off, contract support, credits issued after year endRecurring, contracted revenue is worth more than project revenue
Customer concentrationRevenue by customer by month, contract terms and renewal datesLosing one large customer can change the whole valuation
Net working capital pegThe normal monthly level of receivables, inventory, payables and accrualsThe price moves at closing if working capital is above or below the peg
Debt-like itemsDeferred revenue, customer deposits, accrued bonuses, unpaid taxes, lease liabilitiesEach one is deducted from the price like debt
Proof of cashReported revenue and expenses tied to bank deposits and withdrawals, month by monthRevenue that never reached the bank is not revenue a buyer will pay for

Revenue quality starts with timing. Under ASC 606, revenue is recognized as promised goods or services are transferred to the customer, in the amount the company expects to be entitled to (FASB, Topic 606). Books that record revenue when the cash arrives can show a strong year that belongs partly to the year before, or a year-end spike that reverses in January.

The working capital peg moves money at closing. A buyer expects the business to be handed over with a normal level of receivables, inventory and payables. The review measures that level over a trailing period, and the purchase agreement sets it as the peg: if working capital at closing comes in below the peg, the price usually comes down. Receivables that are too old to collect get excluded, which is why aging matters.

Debt-like items are obligations that are not bank loans but still cost the buyer cash after closing. Leases are a common one: under ASC 842, a lessee records a lease liability and a right-of-use asset for leases longer than twelve months (FASB, Topic 842).

Proof of cash is the simplest test and the hardest to argue with. The reviewer ties each month's revenue to deposits and each month's expenses to withdrawals. Every difference needs an explanation, whether timing, a transfer between accounts or an owner deposit.

What does a QoE find in practice?

In one review we ran ahead of a transaction, management had communicated EBITDA of $800,000 for a business with $2.07 million in revenue. Rebuilt from the general ledger, EBITDA was $679,819: a $120,181 overstatement, about 15 percent, found before the deal rather than after it. The work followed a quality of earnings approach and is written up in full in our financial due diligence case study.

The EBITDA gap was not the only finding:

  • Concentration. 99.9% of revenue came from two clients, and every statement of work with both had expired on December 31, 2025 with no signed replacements.
  • Receivables. $1.071 million, 75.3% of total assets, at roughly 189 days outstanding. Management did not permit independent confirmation of the balances.
  • Governance. An executive card balance suggested personal charges settled through the company.

None of it was fraud. It was accrual timing, unreconciled accounts and a management report that had drifted from the books over several years. Priced on a multiple of EBITDA, the gap was worth far more than $120,181, and every cause was preventable with a proper monthly close.

Sell-side or buy-side QoE: which one do you need?

The analysis is the same; who commissions it, and when, is not.

What mattersSell-side QoEBuy-side QoE
Commissioned byThe sellerThe buyer, or its lender
WhenBefore the business goes to marketAfter a letter of intent, during exclusivity
PurposeFind and fix issues while there is still time, and support the asking priceTest the seller's numbers before the price is final
What it changesFewer surprises in diligence and less room to renegotiatePrice, earn-outs, escrow and the warranties in the purchase agreement

A sell-side review rarely stops the buyer from running its own. It changes what the buyer finds: issues already explained or fixed, instead of a surprise that reopens the price after the letter of intent.

When should you get a QoE, and how long does it take?

Consider a quality of earnings review when any of these is on the calendar:

  • A sale of the company, ideally a year or more before you go to market.
  • A recapitalization, a minority investor or a partner buyout, where a price is set on EBITDA.
  • A large loan where the lender sizes the facility on earnings.
  • An acquisition you are making, where you need to test the seller's numbers.

How long it takes depends on the books. When every month is closed and reconciled, the analysis is a matter of weeks, most of it spent collecting contracts, payroll detail and bank statements. When the books are behind, the cleanup comes first and often takes longer than the review. That is the case for starting early: a buyer wants a run of clean months, not one year cleaned up in a hurry.

How do you prepare your books before a sale?

Most QoE findings trace back to the monthly books. These steps remove them at the source.

  1. 1Close every month on a calendar. A fixed close date, the same steps in the same order, and a locked period at the end. Our month-end close checklist sets out the sequence.
  2. 2Reconcile every account to its statement. Bank, card, loan and merchant accounts, every month. This is what makes the proof of cash pass.
  3. 3Keep the books on an accrual basis. Income in the period it is earned and expenses in the period they are incurred, as the IRS describes the accrual method. A buyer will convert cash-basis books anyway, and the conversion is where findings appear.
  4. 4Separate owner spending. Stop running personal costs through the company, and document any add-back you intend to claim, with evidence, when it happens.
  5. 5Record every liability. Accrued payroll and bonuses, payroll and sales taxes, customer deposits and deferred revenue. Unrecorded liabilities become debt-like items in the buyer's model.
  6. 6Clean up receivables. Age them monthly, chase what is collectable and write off what is not, so the working capital peg is set on real balances.
  7. 7Get contracts signed and filed. Customer agreements, renewals and statements of work, with revenue by customer by month ready to hand over.
  8. 8Tie management reports to the ledger. If a number on a slide cannot be traced to a journal entry, a buyer will treat it as an opinion, not a number.

If the books are months behind, catch-up bookkeeping rebuilds and reconciles the backlog first; monthly bookkeeping and payroll then keeps every month closed through the sale.

What red flags do buyers find in a QoE?

These are the findings that reopen a price or add an earn-out:

  • An EBITDA that does not trace to the ledger. The deal sheet and the general ledger disagree.
  • One-time costs that happen every year. Buyers put recurring add-backs back.
  • Revenue in the wrong period. Sales booked when cash arrives, or a year-end spike that reverses in January.
  • Concentration with expiring contracts. A few customers, on terms that end inside the deal horizon.
  • Old receivables. Balances aging past collection, or that cannot be confirmed.
  • Missing liabilities. Accrued payroll, bonuses, taxes or customer deposits never recorded.
  • Personal spending in the business. It weakens every add-back you claim, including the valid ones.
  • Deposits that do not tie to revenue. A proof of cash with unexplained differences.

What else do owners ask about quality of earnings?

What is the difference between a quality of earnings report and an audit?+
An audit gives an opinion on whether the financial statements are fairly presented. A quality of earnings report gives no opinion. It tests whether EBITDA is real and recurring, and what working capital and debt-like items a buyer will inherit.
Who pays for a quality of earnings report?+
The party that commissions it. A seller pays for a sell-side review before going to market. A buyer, or its lender, pays for a buy-side review after a letter of intent.
What is a net working capital peg?+
The normal level of working capital, usually receivables and inventory less payables and accrued expenses, that a buyer expects the business to have at closing. If working capital at closing differs from the peg, the purchase price is adjusted.
Can a quality of earnings review be done on cash-basis books?+
Yes, but the reviewer first converts the numbers to an accrual basis, so income and expenses land in the periods they belong to. Moving to accrual books before a sale saves that step and removes a common source of findings.
How far ahead of a sale should I prepare my books?+
Ideally a year or more, so a buyer sees a run of closed, reconciled months on an accrual basis rather than a single year cleaned up just before the sale.
