You're About to Be Under a Microscope. Here's What the Buyer's Team Is Really Looking For.
You've spent fifteen years building your business. Revenue is strong and EBITDA looks healthy. A buyer has expressed interest, and you're starting to imagine the finish line. Then their due diligence team arrives — and within two weeks, they've found $1.2 million in EBITDA adjustments that don't hold up, a customer concentration problem you never thought about, and a working capital gap that knocks 20% off the purchase price.
This is what a quality of earnings report does to unprepared sellers.
A quality of earnings analysis (commonly called a "QoE") is the single most important financial exercise in any acquisition. It's not an audit or a tax return review. It's a forensic examination of whether your reported earnings are real, repeatable, and sustainable after the buyer takes over. And the team conducting it has one job: to find every dollar of EBITDA that isn't what it appears to be.
With 33.3 million small businesses in the U.S. according to the SBA, buyers have no shortage of alternatives. If you're a business owner contemplating an exit in the next 12–36 months, understanding what is quality of earnings in an acquisition isn't optional. It's the difference between getting your asking price and watching your valuation erode in real time during the deal process.
A Quality of Earnings (QoE) report is a forensic financial analysis used during acquisition due diligence to verify whether a seller's reported EBITDA is sustainable and repeatable. Buyers' QoE teams aggressively challenge add-backs, revenue quality, customer concentration, and working capital—unprepared sellers typically lose 15–30% of their valuation. Start preparing at least 90 days before going to market with clean financials, documented adjustments, and revenue segmentation.

What a Quality of Earnings Report Actually Is
A quality of earnings report is a financial analysis commissioned during the due diligence phase of a business acquisition. Typically, the buyer hires an independent accounting firm (usually a Big Four or a mid-market transaction advisory practice) to tear apart the seller's financials and answer one fundamental question: Is the EBITDA real?
More specifically, the QoE team is trying to determine:
- Is the reported EBITDA sustainable, meaning will it continue at this level after the acquisition closes?
- Is the revenue repeatable, or is it driven by one-time contracts, related-party transactions, or aggressive recognition policies?
- Are the expenses normalised, or has the owner been running personal expenses through the business, underpaying market-rate salaries, or deferring necessary maintenance?
- Is the working capital adequate, or will the buyer need to inject cash on day one to keep the business running?
- Are there hidden liabilities: pending litigation, unrecorded tax obligations, deferred revenue that hasn't been earned, or off-balance-sheet commitments?
The QoE is not an audit. An audit tells you whether financial statements comply with accounting standards. A QoE tells you whether those numbers represent economic reality. A company can pass an audit with a clean opinion and still have its EBITDA slashed by 40% in a quality of earnings review. That gap catches most sellers off guard.
Quality of Earnings = "Are these numbers real, repeatable, and sustainable?"
The audit looks backward at compliance. The QoE looks forward at what the buyer is actually purchasing.
The output of a QoE typically includes an adjusted EBITDA bridge: a waterfall that starts with reported EBITDA and walks through every adjustment (up or down) to arrive at what the buyer considers "true" recurring EBITDA. According to PitchBook data, deal valuations increasingly depend on adjusted EBITDA, and this adjusted number is what drives the purchase price. If you reported $5M in EBITDA and the QoE adjusts it down to $3.8M, and the deal is priced at 6x EBITDA, you just lost $7.2 million in enterprise value.
That's why preparation matters. And that's why understanding what buyers look for, before they start looking, is the most valuable exercise a business owner can undertake. Your management accounts are the foundation this entire analysis is built on.
EBITDA Adjustments: The Battleground of Every Deal
Every seller presents "adjusted EBITDA" — the reported number plus add-backs for items the seller considers non-recurring or non-operational. Every buyer's QoE team then systematically challenges those adjustments. This negotiation is where deals are won, lost, or repriced.
Here are the adjustments buyers scrutinize most aggressively:
Owner Compensation Add-Backs. If the owner takes $500K in salary but a replacement CEO would cost $250K, the seller adds back $250K. Sounds reasonable, but the QoE team will benchmark that replacement cost against actual market data. The Bureau of Labor Statistics reports the median financial manager salary at $156,100 per year, and buyer teams use benchmarks like these aggressively. If they determine a replacement CEO costs $300K, not $250K, your add-back just dropped by $50K. At 6x EBITDA, that's $300K off the purchase price.
One-Time Expenses. Sellers routinely add back legal fees, consulting projects, relocation costs, and litigation settlements as "non-recurring." The QoE team looks at your historical pattern. If you've had "one-time" legal expenses in three of the last five years, that's not one-time. That's a cost of doing business. They'll reverse the add-back and treat it as a recurring expense.
Related-Party Transactions. If you're leasing your building from an LLC you own, paying your spouse as a consultant, or buying materials from a family member's company, the QoE team will benchmark every one of those transactions against market rates. If your rent is $8K/month but market rate is $12K, they'll add $4K/month ($48K/year) to expenses, reducing EBITDA by that amount.
Pro Forma Adjustments. Some sellers add back costs for initiatives they plan to implement: "We're going to consolidate these two warehouses and save $200K/year." The QoE team's response: Have you done it yet? If not, the adjustment doesn't count. Buyers pay for what exists, not what you plan to do.
Revenue Quality: Not All Revenue Is Created Equal
A QoE team doesn't just look at how much revenue you generate. They examine the quality of that revenue. Two companies with identical top-line numbers can have radically different valuations based on how that revenue is composed.
Recurring vs. Non-Recurring Revenue. Subscription revenue, long-term contracts, and retainer-based relationships are worth more than project-based, one-time, or transactional revenue. If 80% of your revenue comes from recurring contracts with automatic renewals, buyers pay a premium. If 80% comes from new project wins each year, the buyer is essentially purchasing a sales pipeline, which is inherently riskier.
Revenue Recognition Timing. The QoE team will scrutinize when you recognise revenue. Are you recognising revenue at contract signing, at delivery, or at payment? If your recognition is aggressive — booking revenue before the service is delivered or the product is shipped, the QoE will restate your revenue to a more conservative basis. This alone can shift EBITDA by hundreds of thousands of dollars.
Channel Mix and Margin by Revenue Stream. Buyers want to see revenue broken down by product line, service type, geography, and channel, with gross margins for each. A blended 40% gross margin looks good until the QoE reveals that your highest-growth segment operates at 22% margin while your declining legacy segment operates at 55%. The buyer is purchasing the future, and the future margin profile might look very different from the historical average.
Backlog and Pipeline Integrity. If you have a contract backlog, the QoE team will verify it: Are these signed contracts? Are they cancellable? What's the historical conversion rate from backlog to revenue? A $5M "backlog" of unsigned proposals is worth approximately nothing.
Customer Concentration: The Silent Deal Killer
If one customer accounts for more than 15–20% of your revenue, the buyer's QoE team will flag it as a material risk. If one customer accounts for more than 30%, it may kill the deal entirely, or restructure it with a significant earn-out tied to that customer's retention.
Here's why: the buyer is purchasing future cash flows. If 35% of your revenue walks out the door because one customer decides not to renew, or because that customer had a personal relationship with you (the founder) that doesn't transfer, the buyer just lost 35% of what they paid for. No sophisticated buyer takes that risk at full price.
The QoE team will analyse:
- Top 10 customer revenue concentration: revenue and margin contribution by customer, trended over 3 years
- Customer tenure: how long each major customer has been with you, and whether the relationship is contract-based or handshake-based
- Revenue trend by customer: is revenue from your top customers growing, stable, or declining?
- Contractual protections: are there signed agreements with termination clauses, or could the customer leave tomorrow?
- Key person dependency: does the relationship exist because of you personally, or because of your company's systems and service quality?
10–20% per customer: Moderate risk. Expect deeper diligence on that relationship.
20–30% per customer: High risk. Likely earn-out or holdback provisions tied to retention.
Over 30% per customer: Deal-threatening. May require that customer to sign a long-term commitment pre-close.
Working Capital: The Number That Moves the Purchase Price
Working capital is one of the most misunderstood, and most consequential, elements of a quality of earnings analysis. Most business owners think the purchase price is simply EBITDA × multiple. In reality, it's EBITDA × multiple, plus or minus a working capital adjustment.
Here's how it works: the buyer and seller agree on a "target" level of net working capital, typically the trailing 12-month average of current assets minus current liabilities (excluding cash and debt). If the business is delivered at close with working capital above the target, the seller gets the excess. If below, the purchase price is reduced dollar-for-dollar.
The QoE team will calculate normalised working capital by:
- Stripping out anomalies: unusually high receivables collected just before close, prepaid expenses accelerated to inflate current assets, or payables deliberately stretched to reduce current liabilities
- Identifying seasonal patterns: if your business is seasonal, working capital needs vary dramatically month to month; the QoE team will use a methodology that captures the true run-rate need
- Examining trends: if your working capital has been declining over 3 years while revenue has been growing, that signals under-investment or deteriorating collection quality
- Separating operating from non-operating items: related-party receivables, intercompany balances, and non-trade items get excluded from the working capital calculation
The working capital adjustment is where sellers most frequently lose unexpected value. A seller might negotiate a $30M purchase price only to discover at closing that normalised working capital is $400K below the target — resulting in a $400K purchase price reduction that nobody on the sell side anticipated.
Understanding the mechanics of your cash conversion cycle is essential. If you haven't been tracking the relationship between profit and actual cash flow, you're walking into a QoE blind.
Off-Balance-Sheet Items: What Buyers Find That You Forgot
Some of the most damaging QoE findings come from liabilities that don't appear on the balance sheet at all. These are obligations the business has incurred but hasn't recorded, either because of accounting limitations, oversight, or deliberate omission.
The QoE team will hunt for:
Operating Leases and Commitments. Under older accounting standards, many leases lived off-balance-sheet. Even under ASC 842 (which brought most leases onto the balance sheet), the QoE team will review all lease agreements, employment contracts, vendor commitments, and purchase obligations to quantify the full picture of future commitments.
Pending or Threatened Litigation. Lawsuits, even those without formal filings, represent contingent liabilities. The QoE team will request a litigation summary from your legal counsel and assess potential exposure. An unrecorded $500K lawsuit settlement reserve can materially change the deal economics.
Deferred Revenue and Unfulfilled Obligations. If customers have paid you in advance for services you haven't yet delivered, that's a liability, not revenue. The QoE team will verify that deferred revenue is properly recorded and that the business has the capacity (and cost structure) to fulfil those obligations post-close.
Tax Exposures. Unfiled returns, aggressive tax positions, potential nexus issues for multi-state operations, or unresolved notices from tax authorities — all of these represent contingent liabilities that the QoE team will surface. Buyers typically require the seller to indemnify against pre-closing tax liabilities, but the discovery process itself creates friction, delay, and distrust.
Employee-Related Liabilities. Accrued vacation, deferred compensation agreements, change-of-control provisions in employment contracts, and unfunded pension or benefit obligations all represent real liabilities that may not be fully recorded on the balance sheet.
The 90-Day Cleanup Plan: Preparing Your Financials for Due Diligence
The businesses that achieve maximum value in a sale are the ones that prepare before the buyer arrives. Deloitte's CFO Signals survey shows 78% of CFOs plan to increase investment in financial planning technology, which reflects how seriously the market takes deal-readiness infrastructure. Here's the 90-day playbook we use with clients who are preparing for an exit.
Days 1–30: Foundation
- Clean up the chart of accounts. Ensure every account has a clear purpose. Eliminate catch-all categories like "Miscellaneous Expense" or "Other Income" — QoE teams treat these as red flags because they often hide reclassifiable items.
- Reconcile every balance sheet account. Bank accounts, AR, AP, accrued liabilities, prepaid assets, fixed assets, loans: all of them. An unreconciled balance sheet is the single fastest way to destroy buyer confidence.
- Document every EBITDA adjustment. Create a schedule with the adjustment description, dollar amount, supporting documentation, and explanation of why it's non-recurring. If you can't support it with evidence, remove it.
- Build a proper management accounts package if you don't already have one. This means P&L, balance sheet, cash flow statement, and KPI dashboard, delivered within 5 business days of month-end. See our guide on management accounts reporting for the full framework.
Days 31–60: Normalisation
- Normalise working capital. Calculate trailing 12-month average. Identify any anomalies. Start managing inventory levels, receivables collection, and payables timing toward a consistent baseline.
- Resolve revenue recognition issues. Ensure revenue is recognised in the correct period under ASC 606. If you have deferred revenue, verify it's properly recorded and that fulfilment obligations are clear.
- Prepare customer and vendor concentration analyses. Build a schedule showing top 10 customers and top 10 vendors by revenue/spend, with trends over 3 years. If concentration risk exists, document the mitigating factors (contracts, diversification strategy, relationship depth).
- Review and document all related-party transactions. Benchmark every related-party arrangement against market rates. If any transaction is below market, adjust your go-forward projections to reflect the true cost.
- Calculate the ROI of your financial leadership to understand how investment in proper financial infrastructure pays for itself during the deal process.
Days 61–90: Data Room and Stress Testing
- Build the data room. Organise 3 years of financial statements, tax returns, bank statements, material contracts, lease agreements, insurance policies, employee rosters, benefit plans, litigation summaries, and corporate documents. A well-organised data room communicates competence and transparency — it sets the tone for the entire diligence process.
- Commission a sell-side QoE. Hire a transaction advisory firm to perform a quality of earnings analysis on your own financials — before the buyer does. This lets you identify and address issues proactively, control the narrative, and avoid surprises.
- Stress-test your own numbers. Ask yourself: If I were buying this business, what would concern me? Look at your financials through the buyer's lens. Challenge your own adjustments. Question your own revenue quality. This exercise alone is worth its weight in gold.
- Brief your management team. Your CFO/controller and key managers will be interviewed during diligence. Ensure they understand the financial narrative, can speak to trends and anomalies, and know what not to volunteer (there's a difference between transparency and offering unstructured information that creates new threads for investigation).

Why Your CPA Alone Isn't Enough
Your CPA is essential for tax compliance, annual financial statement preparation, and ongoing tax planning. The AICPA reports that nearly 60% of SMBs say understanding financial data is a challenge, so it's no surprise that most CPAs, even excellent ones, don't have the skillset required for QoE preparation. Here's why:
| Capability | CPA / Tax Accountant | Fractional CFO with PE Experience |
|---|---|---|
| Tax Compliance | ✅ Core expertise | Works alongside CPA |
| GAAP Financial Statements | ✅ Annual preparation | Monthly management accounts |
| EBITDA Normalisation | Limited exposure | ✅ Knows what buyers challenge |
| Working Capital Modelling | Not typically performed | ✅ Deal-critical expertise |
| Buy-Side Perspective | Rarely has this experience | ✅ Has been the buyer's analyst |
| Data Room Preparation | Can contribute documents | ✅ Builds and manages the process |
| Revenue Quality Analysis | Not in scope | ✅ Segments, trends, and cohort analysis |
| Management Interviews Prep | Not typically involved | ✅ Coaches team on diligence process |
This isn't a criticism of CPAs. They're outstanding at what they do. But QoE preparation is a different discipline entirely. It requires someone who has sat across the table from a buyer's due diligence team and knows exactly what they're going to ask, what they're going to challenge, and what will make them walk away.
Your CPA handles your taxes. A fractional CFO with deal experience handles your exit readiness. You need both, and confusing their roles is one of the most expensive mistakes sellers make.
Frequently Asked Questions
What is a quality of earnings report in an acquisition?
A quality of earnings (QoE) report is a detailed financial analysis performed during acquisition due diligence, typically by an independent firm hired by the buyer. It goes beyond a standard audit to examine whether reported EBITDA is sustainable and repeatable by identifying non-recurring revenue, questionable add-backs, aggressive accounting policies, customer concentration risks, working capital anomalies, and off-balance-sheet liabilities. The results directly impact the purchase price, deal structure, and whether the buyer proceeds at all.
How does a quality of earnings report differ from an audit?
An audit confirms that financial statements comply with GAAP or IFRS. It's a backward-looking compliance exercise. A QoE report is forward-looking and deal-specific. It asks: Is this EBITDA real? Will it continue after the acquisition? Auditors verify accuracy; QoE analysts assess sustainability, quality, and risk. Many companies pass an audit with a clean opinion and still see their valuation slashed by a QoE report.
What EBITDA adjustments do buyers challenge most often?
The most frequently challenged adjustments include above-market owner compensation add-backs, "one-time" expenses that actually recur every few years, related-party transactions priced below market, revenue recognised too aggressively, personal expenses run through the business, and pro forma cost savings that haven't actually been implemented. The general rule: if you can't prove it with documentation, the buyer's QoE team will reverse it.
How long does it take to prepare for a quality of earnings review?
A proper sell-side QoE preparation takes 90 days minimum. The first 30 days focus on cleaning up the chart of accounts, reconciling the balance sheet, and documenting every adjustment. Days 31–60 cover working capital normalisation, revenue recognition review, and customer/vendor concentration analysis. Days 61–90 involve building the data room, commissioning a sell-side QoE, and stress-testing your numbers. Companies that skip this preparation typically leave 15–30% of their valuation on the table.
Why isn't my CPA enough to handle quality of earnings preparation?
Most CPAs are experts in tax compliance and annual financial statement preparation, not M&A due diligence. QoE preparation requires understanding how buy-side analysts think, what adjustments will survive scrutiny, how to present working capital trends, and how to structure a data room that builds buyer confidence. You need someone who has been on the buy side, someone who has personally scrutinised acquisition targets and knows what kills deals. Your CPA handles taxes. A fractional CFO with PE experience handles deal readiness.
