A quality of earnings (QoE) review tests whether a company’s reported profits are supported by its underlying records and likely to be repeatable. For an owner considering a sale, the useful question is not simply, “What is our adjusted EBITDA?” It is, “Which parts of that number can a buyer independently verify?” Preparing that answer before diligence can expose gaps while there is still time to address them.

What a Quality of Earnings Review Examines

Financial due diligence looks beyond the annual statements. A reviewer may reconcile monthly revenue and costs to the general ledger, examine gross-margin trends, test whether revenue belongs in the reported period, and ask whether proposed EBITDA adjustments are truly nonrecurring. Customer mix, cash conversion and the company’s normal working-capital needs can matter too. The exact scope depends on the business and the transaction.

A QoE review is not the same as a financial-statement audit. An audit addresses whether statements are fairly presented under the applicable accounting framework. A transaction review asks additional commercial questions, including what a buyer can reasonably expect the business to earn after closing. One does not automatically replace the other.

Start With a Reconciliation, Not a Headline Number

A practical preparation file begins with a bridge from reported net income to EBITDA and then to any proposed adjusted EBITDA. For each adjustment, record the amount, period, ledger account, invoice or payroll record, explanation, and whether a buyer would incur a similar cost after closing. Separate accounting corrections from discretionary adjustments: they are different questions.

For example, an owner’s personal expense recorded in the company books may be supportable as an adjustment if documentation is clear and the expense would not continue. By contrast, a recurring recruiting cost or a normal equipment-maintenance expense should not be labeled “one-time” merely because its amount varied. This is a classification example, not a claim that any particular adjustment will be accepted in a transaction.

A Five-Part Seller Readiness File

The following is a working checklist, not a substitute for an accountant’s diligence scope. Its value is that every assertion points to a document a reviewer can inspect.

1. Monthly financial bridge: Tie management reports to the trial balance and annual statements; explain any changes in account mapping or accounting policy.
2. Adjustment register: Attach evidence for each proposed EBITDA add-back and identify any offsetting costs needed to operate the business without the owner.
3. Revenue and margin view: Show monthly performance by meaningful product, service or customer group; investigate unusual period-end entries, returns and margin shifts.
4. Customer and contract file: Reconcile the revenue schedule to invoicing and explain renewals, concentration, pricing changes and contract terms. Our customer concentration guide offers a more detailed view of this workstream.
5. Cash and working-capital bridge: Explain receivables, inventory, payables and seasonality alongside earnings. A QoE finding does not by itself settle the working capital target negotiated in a sale agreement.

When Is an External Sell-Side Review Worth Considering?

Not every owner needs the same engagement. An external sell-side QoE review may be useful where financial reporting is complex, adjustments are material or contested, or a competitive process will involve several sophisticated buyers. A narrower readiness assessment may be more proportionate for a simpler business or an earlier planning stage. The choice should reflect the records, likely buyers, timetable and cost, not a claim that one report guarantees a price or closing.

The preparation sequence matters. First establish reliable monthly records and investigate discrepancies. Then decide with an independent accounting adviser whether a full review is warranted. Finally, align any findings with the broader sell-side process and the information shared with buyers. Do not let a polished adjusted-EBITDA schedule conceal unresolved issues in revenue recognition or cash conversion.

The Practical Takeaway

A defensible earnings story is a traceable one. If each important figure can be reconciled to the books, each adjustment has evidence, and unusual trends have a candid explanation, the seller can respond to diligence questions more effectively. Have qualified accounting and legal advisers assess the actual facts and transaction documents before relying on a particular earnings measure or agreeing to price terms.
