Most owners discover too late that the price written in a letter of intent is not the price that survives diligence. The fastest way to protect that number is to commission a sell-side Quality of Earnings (QoE) review early, supported by professional audit and assurance services that normalize your monthly financials before a buyer ever opens your books. A QoE is not the same as an audit, but the credibility it carries depends on the same disciplined verification that defines assurance work, and that combination is what keeps a deal from unraveling at the eleventh hour.
Quick answer: A Quality of Earnings review is an independent analysis that tests whether your reported EBITDA is real, recurring, and supported by your monthly financial records. Commissioning one before you go to market, ideally 6 to 12 months ahead, lets you find and fix the adjustments, working capital gaps, and revenue concentration issues that buyers use to cut price. The goal is to walk into negotiations with a defensible normalized earnings figure rather than defending surprises after a buyer’s accountants find them first.
What a Quality of Earnings Review Actually Examines
A QoE review starts with your trailing twelve months of monthly financials and rebuilds earnings from the transaction level up. Rather than accepting the net income on your tax return, the reviewer reconstructs revenue, cost of goods sold, and operating expenses month by month to confirm that the trend a buyer is paying for is genuine. This monthly granularity matters because annual figures hide seasonality, one-time spikes, and timing distortions that change how a buyer values the business.
The centerpiece of the analysis is normalized, or adjusted, EBITDA. The reviewer strips out items that will not continue under new ownership: the owner’s above-market compensation, personal expenses run through the company, one-time legal settlements, and non-recurring repairs. Each of these adjustments, called add-backs, increases the earnings a buyer can reasonably expect, but only if the supporting documentation holds up. An add-back without an invoice, a contract, or a clear paper trail is the first thing a buyer’s team will challenge.
Beyond earnings, a QoE evaluates revenue quality and customer concentration. A company where one client drives 40 percent of sales carries more risk than one with a diversified base, even at identical revenue. The review also tests whether revenue is recognized consistently and whether reported margins reflect operations or accounting choices. These judgments draw directly on the verification rigor found in formal audit and assurance services, where the standard is evidence rather than assertion.
The output is a report a buyer can read and trust without re-performing every step. A well-built QoE reconciles each adjustment back to the books, ties revenue to invoices and contracts, and shows the working capital pattern across the year. When a buyer can follow that trail, the review functions as a shared reference point rather than a sales document, and that shared footing is what speeds a deal toward close.
Why Owners Should Commission a QoE Early
The most common deal-killer is not a low offer; it is a surprise discovered during the buyer’s confirmatory diligence. When a buyer’s accountants find an unsupported add-back, an unrecorded liability, or a working capital shortfall, they do not simply adjust the number. They lose confidence in everything else management has presented, and that erosion of trust is what triggers re-trades, escrow demands, and walked deals. A sell-side QoE done in advance removes those surprises by surfacing them while you still control the narrative.
Timing is leverage. A QoE commissioned 6 to 12 months before going to market gives you room to correct bookkeeping inconsistencies, clean up intercompany entries, document add-backs properly, and build the monthly reporting cadence buyers expect. Trying to assemble this evidence after a letter of intent is signed compresses the work into a 60 to 90 day exclusivity window, exactly when you have the least negotiating power. Early preparation converts what would be a reactive scramble into a controlled process.
There is also a defined working capital target to settle before negotiations begin. Most middle-market deals are structured on a cash-free, debt-free basis with a normalized working capital peg, and disputes over that peg routinely cost sellers real money at close. A QoE establishes a supportable working capital baseline from your monthly balance sheets so the peg is grounded in data rather than negotiated under pressure. Pairing the QoE with experienced transaction advisory support ensures that baseline is framed correctly in the purchase agreement.
Early work also buys time for the parts of the story that cannot be fixed in a hurry. A revenue concentration problem, for example, may take several quarters of new-customer activity to soften, and a margin trend reads very differently once a full year of clean months supports it. By starting before you go to market, you give the business room to show improvement on its own terms rather than asking a skeptical buyer to take that improvement on faith.
How Does the 2026 Middle-Market Backdrop Affect Sellers?
Deal conditions in 2026 reward sellers who are prepared and punish those who are not. EY-Parthenon, in its outlook released June 2, 2026, projects an 8 percent increase in US deal volume for transactions over $100 million, with corporate M&A volume expected to rise 11 percent while private equity volume stays roughly flat against 2025. That divergence means strategic and corporate buyers are leading activity, and corporate development teams tend to run thorough, documentation-heavy diligence.
A more active market does not loosen scrutiny; it sharpens it. When buyers have more targets to choose from, a clean, pre-vetted financial package becomes a differentiator that keeps your deal at the front of the line. Sellers who arrive with a credible normalized EBITDA figure and organized monthly support shorten diligence and reduce the openings a buyer has to renegotiate. Sellers who arrive without one cede that advantage.
Higher activity also means buyers and their advisers see more deals and recognize patterns faster. Aggressive or poorly supported add-backs are flagged almost immediately, and the credibility cost is steep in a competitive process. The discipline of preparing as if a buyer’s accountants are already in the room is the practical mindset a sell-side QoE enforces.
How Do You Build Defensible Add-Backs and Avoid Non-GAAP Traps?
Add-backs are where most value is won or lost, because every dollar of defensible adjustment can translate into several dollars of enterprise value at typical multiples. The discipline is straightforward: each adjustment needs documentation a third party can verify. Owner compensation above market needs a benchmark; personal expenses need to be identified line by line; one-time costs need proof they will not recur. Adjustments that fail this test get rejected, and a pattern of weak add-backs casts doubt on the credible ones.
Because normalized EBITDA is a non-GAAP measure, the framing principles that govern public-company disclosure are a useful guardrail even for private deals. The SEC’s Compliance and Disclosure Interpretations on non-GAAP financial measures emphasize reconciliation to the most directly comparable GAAP figure and caution against presentations that mislead. Applying that same logic, a strong QoE always reconciles normalized EBITDA back to reported net income so a buyer can trace every adjustment.
A reviewer grounded in formal assurance practice brings the same skepticism the AICPA expects in audit work. The Journal of Accountancy’s ongoing audit and assurance coverage reflects the profession’s standing emphasis on sufficient appropriate evidence and professional skepticism, the exact qualities that make a QoE persuasive to a buyer rather than something to argue about. That credibility is the difference between an add-back that holds and one that gets stripped out at close.
It helps to separate add-backs into tiers as you build the file. Adjustments with clean, external documentation sit in one group and rarely draw a fight; judgment-based normalizations, such as an estimate of above-market rent or owner pay, sit in another and need a defensible methodology behind them. Flagging that distinction yourself, rather than letting a buyer find it, signals candor and tends to preserve the adjustments that matter most.
How Should You Prepare in the Months Before Going to Market?
Start by getting your monthly financials onto an accrual basis and reconciled. Cash-basis books, common in owner-managed companies, distort the period-to-period earnings trend buyers analyze and make normalization far harder. Twelve to twenty-four months of clean, accrual-based monthly statements is the foundation everything else rests on.
Next, assemble the supporting file for every anticipated add-back before the QoE begins. Pull the contracts, invoices, board minutes, and compensation studies that substantiate each adjustment, and resolve intercompany and related-party transactions so they do not raise questions later. The fewer open items the reviewer finds, the stronger and faster the final report.
Finally, treat the QoE as the start of your diligence file, not a standalone deliverable. The same documentation supports the data room, the working capital negotiation, and the representations you will make in the purchase agreement. Coordinating the QoE with your tax advisers and deal counsel early means the financial story you tell buyers is consistent across every workstream, which is precisely what sustains a deal through to close.
It also pays to assign ownership of the process internally before the work starts. Someone on the management team should be responsible for producing documents on request, answering reviewer questions quickly, and keeping versions straight, because diligence stalls when requests sit unanswered. A seller who responds within a day signals control of the business, and that impression carries weight in every later conversation about price.
Frequently Asked Questions
How is a Quality of Earnings review different from an audit?
An audit expresses an opinion on whether financial statements are fairly presented under GAAP for a historical period. A QoE is forward-looking and deal-focused: it normalizes earnings, tests the sustainability of revenue, and quantifies adjustments a buyer should consider. A QoE often relies on audited or reviewed financials as a starting point, but it answers a different question, namely what a buyer can reasonably expect to earn going forward.
When should I commission a sell-side QoE?
Ideally 6 to 12 months before you go to market. That window gives you time to correct bookkeeping issues, document add-backs, and establish a defensible working capital baseline while you still control the process. Waiting until after a letter of intent is signed forces the work into a short exclusivity period when your leverage is lowest.
Will a QoE actually increase my sale price?
It can, in two ways. First, properly supported add-backs raise normalized EBITDA, and at common middle-market multiples each dollar of defensible adjustment can lift enterprise value meaningfully. Second, a clean report reduces the surprises buyers use to justify re-trades, which protects the price you negotiated rather than watching it erode in diligence.
What documentation should I gather before the review begins?
Twelve to twenty-four months of accrual-based monthly financial statements, plus support for every expected add-back: owner compensation benchmarks, invoices for one-time costs, contracts behind major revenue streams, and records of any related-party transactions. The more complete this file is at the outset, the stronger and more credible the final QoE will be.
