Five years ago, quality of earnings (QoE) reports were a private-equity convention reserved for ecommerce deals north of $10M in SDE. In 2026, they are showing up in transactions as small as $1M SDE, and the trajectory is clear. Serious institutional buyers, family offices, and the new wave of search funds are no longer willing to underwrite an ecommerce acquisition on the seller’s bookkeeper-prepared P&L alone. They want a third-party financial expert to confirm that the earnings number on the cover page is real, repeatable, and free of the small accounting tricks that quietly inflate ecommerce SDE.
For sellers, this shift changes the math of preparation. A QoE engagement, whether ordered by the buyer or commissioned proactively by the seller, can validate your number and accelerate close, or it can surface findings that strip six and seven figures off your final price. Knowing exactly what a QoE provider looks at, the patterns that trigger downward adjustments, and how to prepare your books so the report comes back clean is one of the highest-leverage things a founder can do in the 6 to 12 months before going to market.
This guide breaks down what a quality of earnings report is, why it now matters at the lower middle market, what providers actually examine inside an ecommerce business, and the specific findings that most often reprice or kill deals at the QoE stage. If you have not yet built out the broader documentation set buyers will ask for, start with the DTC Due Diligence Checklist 2026 and come back here once your data room is organized.
What a Quality of Earnings Report Actually Is (And How It Differs From an Audit)
A quality of earnings report is a focused financial analysis performed by an accounting firm (or a specialist M&A diligence provider) on behalf of a buyer or seller in an M&A transaction. Its purpose is narrow and specific. Verify that the trailing 12 to 24 months of earnings the seller is representing are accurate, sustainable, and free from one-time, owner-specific, or accounting-driven distortions that a buyer should not pay a multiple on.
A QoE is not an audit. Audits opine on whether financial statements as a whole are presented fairly in accordance with GAAP. A QoE narrows its scope to the earnings figure the deal is being priced on, and goes deeper than an audit would on questions a buyer actually cares about: revenue quality, the sustainability of margins, the accuracy of addbacks, and the working capital required to actually run the business at the stated earnings level.
For an ecommerce business, the QoE provider will typically rebuild the trailing 24 months of P&L on an accrual basis from primary source documents (bank statements, processor reports, supplier invoices), reconcile platform revenue to bank deposits, scrub every addback against documentation, and produce an “adjusted EBITDA” or “normalized SDE” figure that the buyer’s offer will be tied to. The difference between the seller’s stated SDE and the QoE-confirmed figure is what the deal price actually closes on.
Why QoE Reports Now Matter at the $1M to $10M SDE Range
Three forces have pushed QoE work downmarket over the last 24 months. Understanding them helps sellers see why their next buyer is far more likely to commission a QoE than buyers were even two years ago.
First, the cost of QoE engagements has fallen. Specialist providers focused on ecommerce M&A now produce buyer-side QoE reports in the $15,000 to $40,000 range for deals in the $1M to $5M SDE band, where the comparable engagement five years ago might have run $75,000 or more. At those price points, a QoE becomes a rational diligence spend even on a $3M deal.
Second, the buyer pool has shifted. Self-funded individual operators are still a meaningful share of FBA and small DTC acquisitions, but institutional capital (search funds, family offices, micro-PE firms) has aggressively entered the lower middle market. These buyers have institutional partners, underwriting committees, and lenders who require third-party financial verification before deploying capital. They will not skip a QoE.
Third, ecommerce-specific issues have made bookkeeper-prepared numbers harder to trust. The proliferation of cash-basis books, the misclassification of inventory purchases as COGS, the under-accrual of customer prepayments and gift card liabilities, and the sloppy handling of platform fees and chargebacks have all made sophisticated buyers skeptical of seller-prepared earnings. A QoE is now their standard answer to that skepticism.
The single most common consequence: deals that would have closed at the seller’s stated SDE in 2023 now routinely close at a QoE-adjusted SDE that is 5% to 20% lower. On a $2M SDE business at 4x, a 10% downward adjustment is $800K off the price.
Buy-Side vs Sell-Side QoE: Who Pays, Who Benefits
QoE reports come in two flavors. The distinction matters because they serve different parties and create different leverage in the deal.
A buy-side QoE is commissioned and paid for by the buyer after the LOI is signed. The report is delivered to the buyer’s deal team and used to validate (or challenge) the seller’s earnings representation. The seller typically has no opportunity to respond before findings are used in a price negotiation. A buy-side QoE is, by design, a buyer-controlled instrument.
A sell-side QoE (sometimes called a “vendor due diligence” report) is commissioned by the seller before going to market. It is delivered to prospective buyers as part of the data room and serves two purposes. It tells the seller exactly where their books are vulnerable so they can clean them up before any buyer sees them, and it signals to sophisticated buyers that the seller has done institutional-quality preparation.
The leverage shift is real. Sellers who hand a buyer a credible sell-side QoE on day one of diligence almost always close at higher multiples, with shorter diligence periods, and with fewer adjustments. Buyers who would otherwise demand a $25K buy-side QoE see one already done. Buyers who would otherwise spend weeks reconstructing the seller’s books see them already reconstructed. The signal alone moves the deal.
The trade-off is cost. A sell-side QoE for a $2M to $5M SDE business typically runs $20,000 to $35,000 and 4 to 6 weeks of seller engagement. For deals where the seller is targeting $4M or more in proceeds, the math almost always justifies the spend. For smaller deals, sellers should at minimum work with their broker or accountant to do an informal QoE prep before listing.
What a QoE Provider Examines Inside an Ecommerce Business
A QoE engagement for an ecommerce business covers four primary domains. Within each, the provider is rebuilding numbers from primary sources rather than accepting the seller’s bookkeeper-prepared P&L as accurate.
Revenue verification and quality:
- Reconciliation of Shopify, Amazon, or other platform gross revenue to merchant processor deposits to bank deposits, month by month for 24 months
- Reclassification of refunds, chargebacks, and platform fees to net revenue lines
- Cohort analysis: do recent customer cohorts retain at rates comparable to older cohorts that are anchoring the LTV story?
- Concentration analysis: revenue concentration by SKU, by customer (for B2B-adjacent DTC), and by acquisition channel
- Channel mix and trend: how has the channel mix evolved over 24 months, and what does that imply about durability?
COGS and gross margin integrity:
- Verification of supplier invoices against COGS recorded in the P&L
- Treatment of inventory: is the seller’s P&L capitalizing inventory correctly, or are inventory purchases being expensed as COGS when received (which inflates GM in low-purchase months and crushes it in high-purchase months)?
- Tariff and freight allocation: are landed costs being properly captured, or is there a meaningful underreporting of true COGS?
- Discount and promotion accounting: are net-of-discount revenue numbers being shown net, or is the P&L double counting?
Operating expense normalization and addback validation:
- Every addback proposed by the seller is examined against source documentation
- Owner compensation is normalized against the cost of a market-rate replacement (the SDE-to-EBITDA bridge)
- One-time expenses, family payroll, personal vehicle and travel, and non-recurring legal or consulting fees are all evaluated for legitimacy and quantified
- Recurring “one-time” items (an addback that appears in every year of the trailing P&L) are almost always rejected
Working capital and cash conversion:
- The level of working capital required to operate the business at the represented revenue and earnings
- Inventory days on hand and any trend toward bloating or aging stock
- Customer prepayment liabilities (especially for subscription and pre-order models)
- Gift card balances and any unredeemed promotional credits
- Days payable to suppliers and any signs of stretched payment terms hiding cash issues
For a deeper walk-through of how the SDE figure itself is constructed (and what addbacks routinely survive scrutiny), see How to Calculate SDE for Your Ecommerce Business in 2026.
The most common revenue verification finding: gross revenue on the seller’s P&L does not match net revenue after platform fees and refunds, and net revenue does not match what hit the bank. Once that gap exists, QoE providers will reconstruct the entire revenue figure from bank deposits up, and the result usually comes in below the seller’s number.
The 6 Most Common QoE Findings That Reprice Deals
Across hundreds of lower-middle-market ecommerce QoE engagements, six findings show up over and over. Each one has a typical magnitude of adjustment, and any single one can be enough to reset the deal price.
1. Unsubstantiated addbacks. The single most common QoE adjustment. Addbacks claimed by the seller that lack receipts, payroll records, or contracts get stripped from the adjusted SDE. On a $1.5M SDE deal at 4x, $80,000 of removed addbacks is $320,000 off the price.
2. Inventory accounting on cash basis instead of accrual. When inventory purchases are expensed in the month received rather than properly capitalized and recognized as COGS when sold, the trailing P&L will show wildly inconsistent gross margins. A QoE will rebuild COGS on an accrual basis, and the smoothed margin almost always comes in lower than the high-margin months the seller is leaning on.
3. Owner labor underpriced. Sellers who pay themselves below market or take all income as distributions force a QoE to add an estimated market-rate replacement salary back into operating expenses. For a founder running a $3M SDE business on $40K of W-2 income, the SDE-to-EBITDA adjustment can be $150,000 or more.
4. Revenue spikes that do not reconcile. A single anomalous month (a viral moment, a one-time wholesale order, a duplicated payout) that materially inflates the trailing 12-month revenue. QoE providers will normalize or remove these, often pulling 5% to 8% out of the headline SDE.
5. Working capital understated. Buyers do not just pay the equity price. They also need to fund the working capital required to operate the business at its current scale. A QoE that identifies a working capital requirement well above what the seller assumed (because of inventory growth, seasonal swings, or supplier term changes) functionally reduces the cash the buyer is willing to put up at close. For more on how this plays out at close, see Working Capital Adjustments in Ecommerce Deals.
6. Customer or SKU concentration that the P&L hides. A QoE that reveals 40% of revenue coming from one SKU, one wholesale customer, or one Amazon listing forces the buyer to price in concentration risk. The result is rarely a deal kill, but it is almost always a multiple compression.
How to Prepare for a QoE Review Before It Starts
The founders who pass QoE cleanly do four things in the 6 to 12 months before going to market. None of them are exotic, and all of them compound.
First, move to accrual-basis bookkeeping with a real ecommerce-aware bookkeeper. Cash-basis books are a near-guaranteed source of QoE adjustments. A bookkeeper who has worked with at least 20 DTC or FBA businesses will know how to handle Shopify and Amazon revenue recognition, inventory capitalization, gift cards, subscription deferrals, and chargeback accounting. The total cost over a 12-month preparation window is typically $4,000 to $12,000. The payoff in defensible SDE is many multiples of that.
Second, document every addback as it happens. Build a running spreadsheet with the date, amount, category, and supporting document for every addback you plan to claim. Owner travel? Note the trip purpose. Family payroll? Have the employment agreement. One-time legal? Have the engagement letter. Addbacks documented in real time survive scrutiny. Addbacks reconstructed after the fact rarely do.
Third, run a reconciliation cadence monthly. At month-close, your bookkeeper should reconcile platform gross revenue to processor deposits to bank deposits and document any variance. A 24-month track record of clean monthly reconciliations is the single strongest signal that the revenue number on the P&L is real.
Fourth, commission an informal QoE prep 6 months before going to market. This does not need to be a full sell-side QoE. A specialist M&A accountant can review your books for 8 to 16 hours and tell you exactly where a buyer’s QoE provider will push back. Fix those issues now, with months of runway, rather than in the middle of a 30-day diligence window.
The most common preparation issue: sellers wait until they have an LOI in hand to start cleaning up their books. By that point, the buyer’s QoE has already started, every adjustment is being made in real time, and the seller has zero leverage to push back. A buyer’s QoE finding a documented and explained issue is a non-event. The same finding hitting the buyer’s deal team cold is a renegotiation.

Bottom Line
Quality of earnings reports are no longer a $10M-and-up deal concept. In 2026, any serious institutional buyer of a $1M+ SDE ecommerce business will commission one, or will expect the seller to have done sell-side equivalent work. The findings reliably reprice deals by 5% to 20%, and the difference between a clean QoE and a messy one is six and often seven figures of final proceeds.
The good news for sellers is that none of the work required to pass a QoE cleanly is mysterious. Accrual bookkeeping with an ecommerce-aware bookkeeper, real-time addback documentation, monthly revenue reconciliation, and an informal QoE prep 6 months before going to market will put you in the top decile of sellers your eventual buyer has ever seen. That position alone protects multiple, accelerates close, and turns the diligence period into the confirmation exercise it should be.
EcomSwap works with DTC and FBA founders on this preparation in the 6 to 18 months before listing. If your goal is to maximize proceeds at close and avoid a renegotiation in the middle of diligence, the time to start is now, while you still have the runway to fix what needs fixing without a buyer watching.
