A Quality of Earnings report is not an audit. It's an independent financial analysis that tells you whether the earnings the seller presented are real — and whether the business's cash flow is as clean as it appears. In mid-market M&A, QoE reports are standard. In $1M–$5M small business acquisitions, most buyers skip them and rely on self-directed financial due diligence. That's often fine. Sometimes it's expensive. Here's how to decide whether the $5,000–$20,000 a QoE costs is worth it on your specific deal.
What a QoE Actually Checks
A Quality of Earnings report is prepared by a CPA firm or financial advisory firm that independently rebuilds the seller's earnings from source documents — not from the CIM or broker package the seller prepared.
A standard SMB QoE report covers:
Earnings normalization. The analyst independently constructs SDE or EBITDA from tax returns, bank statements, and payroll records. Every add-back the seller claimed is tested against documentation. Unsupported add-backs are excluded. The result is an independent earnings figure the analyst can defend.
Revenue quality assessment. Is revenue recurring or project-based? Is the customer base concentrated? Is there revenue the seller counted that a buyer shouldn't rely on — seasonal spikes, one-time contracts, or above-trend periods that aren't representative?
Working capital analysis. Does the business generate cash or consume it? Are receivables collecting on normal terms or piling up? Is inventory current and saleable?
Key accounting policies. How does the seller recognize revenue? Are expenses matched to the right period? Are there accelerated deductions that make current earnings look better than run-rate?
Comparison of tax returns to financials. Do the P&Ls reconcile to the tax returns? Unexplained gaps are a red flag.

QoE vs. Audit vs. Your Own Review
These three processes are often confused. They answer different questions.
An audit is a formal attestation by a licensed CPA that financial statements present fairly in accordance with GAAP. It's expensive ($15,000–$50,000+ for a small business), slow (60–90 days), and answers the question "are these statements prepared according to accounting standards?" — not "will this business cash flow the way the seller says it will?"
Almost no small business sellers have audited financials. If a seller has audited statements, it's unusual and worth noting — it means a CPA has already signed off on the numbers, which reduces (but doesn't eliminate) due diligence risk.
A QoE report is not an audit. The analyst doesn't attest to the financials or issue an opinion under PCAOB or AICPA standards. They verify specific representations — primarily the earnings normalization and revenue quality — and deliver a report on their findings. It's faster (2–4 weeks for a small business QoE) and more focused than an audit.
Your own financial review is what most SMB buyers do: request tax returns, bank statements, and P&Ls, reconcile them yourself, question the add-backs, and make a judgment. This is adequate for straightforward deals with clean books and a seller who is forthcoming with documentation.
The practical decision tree: - Clean books, seller is cooperative, business under $1M SDE, you've done this before → self-directed DD is probably sufficient - Complex add-backs, internally prepared financials, first acquisition, or any deal above $2M purchase price → pay for a QoE - You've already found one discrepancy in self-directed DD → stop and get a QoE before proceeding

Analyze deal economics →Typical Cost by Deal Size
QoE costs scale with business complexity, not directly with purchase price. A $5M manufacturing deal with multiple revenue streams and complex inventory is more expensive to analyze than a $3M professional services firm with a clean P&L and ten customers.
That said, rough ranges by deal size:
| Deal Size | QoE Cost Range | Who Typically Does It |
|---|---|---|
| Under $1M purchase price | $3,000–$7,000 | Local CPA or regional boutique |
| $1M–$3M purchase price | $5,000–$15,000 | Regional boutique or national advisory firm |
| $3M–$5M purchase price | $12,000–$25,000 | Regional or national advisory firm |
| Above $5M | $20,000–$60,000+ | National advisory or Big 4 affiliate |
Who does SMB QoEs: In the $1M–$5M range, QoEs are typically done by regional CPA advisory firms, boutique M&A advisory shops, or the QoE practice arms of mid-size accounting firms. Big 4 affiliates rarely do deals below $5M purchase price. Search for firms that specifically list "buy-side QoE" or "sell-side QoE" as a service — they'll be faster and more focused than a general CPA.
Is SBA financing relevant to the QoE decision? Some SBA lenders require an independent business valuation for loans above certain thresholds, and a few require a QoE for larger acquisitions. Even when not required, having a QoE significantly strengthens your loan application — it provides independent support for the earnings you're asking the lender to underwrite. Lenders who receive buyer-commissioned QoEs tend to process loans faster.
DIY Financial DD Before Paying for a QoE
Before you commit $15,000 to a QoE, run a preliminary self-directed financial review. If the preliminary review surfaces major issues, you either walk away (and saved $15,000 on a dead deal) or escalate to a QoE knowing exactly what to have the analyst focus on.
The 5-step preliminary review:
1. Reconcile tax returns to P&Ls. Take gross revenue from the business tax return and compare to the P&L for the same year. If they don't match exactly, ask why. The explanation should make accounting sense. A gap with no explanation is a red flag.
2. Reconcile P&L to bank deposits. Total the annual bank deposits and compare to P&L revenue. Unexplained differences between bank deposits and reported revenue are the most common sign of manipulated financials.
3. Challenge every add-back. For each add-back the seller claims, ask for the supporting document. Owner salary → payroll record. Personal auto → mileage log and receipts. One-time legal → final settlement document. Add-backs you can't document, you discount.
4. Trend revenue monthly. Annual revenue can mask a business that's deteriorating. Twelve months of monthly revenue shows whether you're buying a growing, stable, or declining business — and whether there are one-time spikes that inflate the annual number.
5. Test the top customers. Request a customer list with revenue per account. Build a concentration table. Confirm the top three customers are under LOI — meaning they're real, not inflated or fabricated.
If Steps 1–5 produce clean results and no significant discrepancies, a QoE may not be necessary for a deal under $2M. If any step produces an unexplained result, escalate to a QoE. The cost of a QoE is trivially small relative to closing on a business with manipulated earnings.
Red Flags a QoE Surfaces That DIY Misses
Experienced QoE analysts know what to look for beyond the standard reconciliation steps. These are the issues most buyers miss on self-directed review.
Revenue timing manipulation. A seller who knows the sale is coming has an incentive to pull forward revenue — invoice a Q1 delivery in December to maximize the trailing-year revenue period. QoE analysts look for revenue timing anomalies in the month-by-month P&L and compare to actual delivery records.
Related-party transactions at non-market rates. The seller may have a supplier relationship with a family member's business, or a lease arrangement with a related party, priced below market. These artificially reduce costs — making EBITDA look better than it would under arm's-length terms. A buyer who takes over will pay market rates.
Vendor concentration risk. One supplier providing 70% of inventory is a supply chain risk that doesn't show up on the income statement. QoE analysts review procurement patterns and flag concentration.
Deferred maintenance hiding in the P&L. A business that hasn't been maintaining equipment properly shows artificially high earnings because maintenance expense is understated. The capital expenditure hit comes after close — when the new owner faces a $40,000 equipment failure that should have been a scheduled $8,000 maintenance item.
Accounting policy changes. If the seller changed how they recognize revenue or accrue expenses in the prior two years, the reported earnings may not be comparable to prior years. QoE analysts identify policy changes and restate earnings on a consistent basis.

Re-run the deal math →Frequently Asked Questions
How much does a QoE cost for a $2M deal?
A Quality of Earnings report for a $2M purchase price acquisition typically costs $8,000–$15,000 depending on the complexity of the financials, the number of years being analyzed, and the firm doing the work. Regional boutique advisory firms and mid-size accounting firm M&A practices are the most common providers at this deal size. Big 4 affiliates rarely take engagements below $5M purchase price. The cost is small relative to the purchase price and the risk of closing on overstated earnings.
Is a QoE required for SBA loans?
A QoE is not a universal SBA requirement, but some SBA lenders require an independent business valuation — and a few require a QoE for larger acquisitions above $250,000–$500,000 in SDE. Even when not required, having a QoE strengthens your loan application by providing independent earnings verification. SBA underwriters are reviewing the same financial claims the QoE analyzes — a buyer-commissioned QoE that confirms the seller's earnings often accelerates underwriting and reduces lender requests for additional documentation.
Can I do quality of earnings myself?
You can do a self-directed financial review that covers the core QoE questions: reconciling tax returns to P&Ls, reconciling P&Ls to bank deposits, challenging add-backs, trending revenue, and testing customer concentration. This is adequate for straightforward deals with clean financials. A professional QoE goes further — analysts look for revenue timing manipulation, related-party transactions, accounting policy changes, and vendor concentration that DIY review typically misses. On any deal above $2M or where you've found one unexplained discrepancy, the professional QoE is worth the cost.
A Quality of Earnings report is insurance, not overhead. On a $2M acquisition where you're writing a $200,000 check at close, a $12,000 QoE that surfaces $150,000 in overstated earnings pays for itself 12 times over. The question isn't whether you can afford a QoE — it's whether the deal is clean enough that you're comfortable without one. When in doubt, run the preliminary self-directed review first. If it comes back clean and the deal is straightforward, you may not need the professional report. If anything comes up questionable, stop and hire a QoE analyst before you close.
