Quality of Earnings (QoE), Explained: What Buyers Actually Get

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.

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.

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.

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 produces source-cited findings — 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 the questions that matter faster. It's how searchers and sponsors review more deals without hiring an analyst, and it pairs naturally with the broader due diligence checklist.

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.

What are add-backs in a QoE? Add-backs are adjustments to reported earnings for items a new owner won't 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 exactly what a buy-side QoE is meant to reject.

Do I need a QoE 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 aren't real. Right-size the scope to the deal size.
