Quality of Earnings: What Buyers Need to Know

QoE is the single highest-return diligence spend a buyer can authorize. A seller-quoted $4.2M EBITDA that quietly contains $600k of one-time pandemic relief, $180k of owner perquisites that the new operator will replace with a $250k hired GM, and $310k of revenue from a customer cohort that has already churned is not a $4.2M business. A real buy-side QoE surfaces that gap in week three and lets the buyer either retrade the price, restructure the deal, or walk before legal fees compound.

This guide is written from the buyer’s chair. If you are the seller looking at this question from the other side, the sell-side QoE companion piece explains why buyers care so much and why you should consider commissioning one before you go to market.

Key Takeaways

• Buy-side QoE exists to validate seller-quoted EBITDA, not to audit historical financial statements.
• Scope covers EBITDA quality, working capital peg, revenue cohort durability, and undisclosed liability sweeps.
• Timeline is six to ten weeks; fees fall in the $25,000 to $75,000 range for sub-$25M EBITDA targets.
• Buy-side and sell-side QoE differ in client, scope, and how reps and warranties insurance treats the findings.
• Common surprises include channel stuffing, related-party leases, capitalized expenses, and missing accruals.
• QoE findings move price (retrade), escrow size, R&W insurance retention, and earnout structure.
• Tier-one providers include RSM, Plante Moran, BDO, Cherry Bekaert, FocalPoint, Riveron, EisnerAmper, Mazars, Withum, and Citrin Cooperman.

What a Quality of Earnings Report Is (From the Buyer’s Perspective)

A quality of earnings report is the financial diligence work product a buyer or lender uses to confirm that the trailing earnings the seller is selling actually exist, are recurring, and will continue under new ownership. It is not an audit. An audit gives an opinion on whether historical statements conform to GAAP. A QoE answers a different question entirely: what is the real, sustainable EBITDA that this business will hand to the next owner.

The QoE provider takes the seller’s adjusted EBITDA schedule and runs it back to first principles. Every addback is tested. Every revenue stream is decomposed. Every working capital line is normalized. The deliverable is a single number the buyer can rely on for valuation, a working capital target both parties will close on, and a punch list of risks that need to be papered into the purchase agreement.

In the lower middle market, where audited financials are rare and seller bookkeeping ranges from clean to creative, the QoE is the only document that gives a buyer the confidence to wire eight figures. Lenders feel the same way. Most senior debt providers in the $5M to $50M check range will not close without a QoE in hand from a name they recognize.

Why Buyers Commission a QoE (Five Concrete Reasons)

Buyers do not commission QoE work because it is a procedural box. They do it because each of the following five outcomes is worth multiples of the fee.

1. Validate seller-quoted EBITDA before signing the purchase agreement

Sellers present an adjusted EBITDA figure on the teaser. Investment bankers polish that figure. By the time the buyer is in exclusivity, the headline number has been through three rounds of optimization. The QoE rebuilds it from the bottom up using bank statements, payroll registers, and the trial balance. In a 2024 RSM benchmarking note, the median buy-side adjustment to seller-quoted EBITDA in deals under $20M EV came in at minus 8 percent. That is the retrade math the QoE pays for.

2. Surface addback issues the seller hopes will pass quietly

Seller addback schedules in lower middle market deals routinely include items that will not survive a QoE. The provider categorizes every addback as accepted, partially accepted, or rejected, with a paper trail for each call. Common rejected addbacks include:

• Phantom owner replacement costs. Seller backs out $80k of owner salary and adds back a $120k assumed replacement; the QoE benchmarks the true market replacement at $225k and the addback collapses.
• One-time legal that is not actually one-time. Same litigation category has hit the P&L three years running.
• Pandemic relief baked into base-year EBITDA. PPP forgiveness, ERTC, and EIDL forgiveness routinely appear above the line on smaller deals.
• Personal travel and vehicle leases coded to the business. Always run, almost never fully addbackable for a buyer who will hold to GAAP.

3. Set the working capital target both parties will close on

The working capital peg is the second-most contested number in any transaction after price. The QoE establishes a normalized monthly working capital baseline, typically a trailing twelve-month average net working capital with seasonality adjustments. Without a defensible peg, the buyer either overpays at closing or fights a true-up battle ninety days later.

4. Stress-test revenue quality by customer cohort

Headline revenue grew 14 percent year over year. The QoE will break that into existing customer expansion, new customer acquisition, cohort churn, and price versus volume. A business growing on the back of two customers that have not signed renewal documents is a different asset than one growing on a diversified cohort that has retained at 96 percent for three years. The QoE shows the buyer which one they are buying.

5. Build the file for representations and warranties insurance

R&W carriers underwrite to the QoE. A clean QoE with thin exceptions yields tighter retention and broader coverage. A QoE with eleven open accounting items and a related-party disclosure that was never papered yields a fat exclusion list, a higher retention, and sometimes a quoted policy that the buyer will not accept. The QoE materially affects the insurance the buyer can buy.

What to Expect From a QoE Provider (Proposal, Scope, Timeline, Fees)

Once the buyer signs an LOI, the QoE engagement runs on a predictable rhythm.

The proposal

Tier-one providers issue a scoping memo within five business days of the kickoff call. The memo lists the trailing period under review (typically TTM plus two prior fiscal years), the in-scope workstreams (EBITDA quality, working capital, revenue, tax, IT optional), the deliverables, and the fee. Buyers should ask three questions of every proposal: who is the partner on the engagement, how many hours of partner time are budgeted, and how the firm handles a finding that requires expanded scope.

The scope

A standard buy-side scope for a $5M to $25M EBITDA target covers:

• Quality of earnings: bottom-up EBITDA rebuild for TTM, plus three years of run-rate analysis.
• Working capital: monthly NWC build, seasonality overlay, recommended peg.
• Revenue analysis: customer concentration, cohort retention, revenue recognition policy test.
• Balance sheet: undisclosed liabilities sweep, debt-like items inventory, accrual completeness.
• Optional add-ons: tax diligence, IT diligence, HR/benefits diligence, ESG diligence.

The timeline

Six to ten weeks from data room access to final report is the realistic band for a clean lower middle market deal. Week one is data request and access. Weeks two through four are field work and management interviews. Weeks five and six produce the draft databook. Weeks seven through nine handle management responses, follow-up testing, and the final report. Sellers with poor books push the timeline to twelve or fourteen weeks.

The fees

Buyers should budget $25,000 to $75,000 for a single-entity, single-state, sub-$25M EBITDA target. Cross-border, multi-entity, or multi-state targets push the fee toward $100,000 to $150,000. Add-on workstreams (tax, IT, HR) typically run $15,000 to $40,000 each. Compared with the median 8 percent EBITDA retrade the QoE supports, the fee pays back many times over on almost every deal.

Buy-Side QoE vs Sell-Side QoE: The Differences That Matter

Both products are called QoE, but they are not interchangeable. A buyer relying on the seller’s vendor due diligence (the seller’s QoE) without commissioning their own work is making a mistake.

The practical answer is that mature buyers always commission their own buy-side QoE even when a sell-side QoE exists. The sell-side report accelerates the data request and gives the buy-side team a head start, but it does not substitute. Underwriters at every major R&W carrier will say the same.

How to Read a QoE Report

A QoE databook is dense, but the structure is consistent across providers. Buyers who know what to look at first can extract the deal-relevant findings in under an hour.

Section 1: Executive summary and EBITDA quality

Skip to the EBITDA bridge first. The bridge shows seller-quoted EBITDA at the top, lists every adjustment the QoE accepted, partially accepted, or rejected, and lands on QoE-adjusted EBITDA at the bottom. The magnitude of the gap is the retrade math. The composition of the gap tells the buyer whether the seller was sloppy, optimistic, or aggressive.

Section 2: Revenue quality and customer analysis

Look for three tables: customer concentration (top ten as percent of revenue, trailing three years), cohort retention (revenue retention by year of first invoice), and revenue mix by service line. A business where the top customer is 28 percent of revenue and has not signed a multi-year contract is a different valuation conversation than one where top customer is 6 percent on a five-year MSA.

Section 3: Working capital and balance sheet

The working capital build is where the closing payment moves. The QoE proposes a peg; the seller will counter. The gap between the two often becomes price. The balance sheet section flags debt-like items the buyer must either pay off at close or carve out of price: accrued bonuses, customer deposits, deferred revenue, capital lease obligations, and unfunded benefit plans.

Section 4: Open items and risk callouts

Every report ends with a list of items the QoE provider could not fully resolve. Read this section as the punch list for definitive document drafting. Each open item should map to a specific representation, an indemnity carve-out, or an escrow holdback.

Red Flags a Good QoE Will Surface

The reason buyers pay for QoE work is that the following issues are rarely visible on the teaser, the CIM, or even the management presentation. They show up in the QoE.

Revenue recognition issues

Channel stuffing in the final month of the period. Multi-year contracts recognized upfront instead of ratably. Bill-and-hold arrangements that do not meet GAAP criteria. Implementation fees booked at signature when service has not started. The QoE tests revenue recognition policy against ASC 606 and flags anywhere the policy is loose.

Related-party transactions

The building is owned by the seller’s spouse’s LLC and the lease is 35 percent below market. The seller’s brother runs an outsourced service at cost. The seller’s daughter is on payroll at $95,000 doing twelve hours a week of social media. Every one of these is an EBITDA risk the buyer needs to know about before signing.

Accounting errors and policy gaps

Capitalized expenses that should have been opex (or the reverse). Inventory counts that do not reconcile to the perpetual system. Missing accruals for vacation, bonus, or 401(k) match. Tax positions that depend on a state nexus call the seller never made.

Hidden or contingent liabilities

Sales-tax exposure in states where the seller has economic nexus but never registered. Pending litigation that was not disclosed. Customer credits accrued in a memo account. Warranty obligations the seller has been expensing as incurred rather than accruing. The QoE’s undisclosed liabilities sweep is one of the most valuable workstreams on the entire engagement.

How QoE Findings Affect Deal Terms

A QoE finding rarely kills a deal outright. What it does is reshape four levers in the purchase agreement.

Purchase-price retrade

If QoE-adjusted EBITDA is materially below seller-quoted EBITDA, the buyer goes back to the seller with the math and either holds the multiple constant (and reduces price) or holds the price constant (and reframes the multiple). The 2024 SRS Acquiom deal study put the share of deals with a post-LOI retrade in the lower middle market at 38 percent, with QoE findings the leading driver.

Escrow size and indemnity caps

A QoE that surfaces material open items pushes the escrow higher (1.5 percent of EV is the floor; deals with significant findings can carry escrows of 5 to 10 percent), and pushes the indemnity cap up alongside it. Specific indemnities for known issues run outside the cap.

Representations and warranties insurance coverage

R&W carriers price retention and exclusions off the QoE. A clean report yields retention at 0.5 percent of EV and a broad policy. A report with eleven open items yields 1.0 percent retention or higher and a list of exclusions for the specific items raised. A handful of carriers will decline to quote at all if the QoE has too many open accounting items.

Earnout, seller note, and rollover structure

If the QoE shows that 22 percent of TTM revenue came from one customer whose contract expires in eight months, the buyer pushes a meaningful slice of price into an earnout tied to renewal. If the QoE flags a working capital deficiency, the buyer pushes the seller into a larger seller note. If the QoE shows EBITDA quality concerns that the seller insists are timing, the buyer pushes a larger rollover so the seller has skin in the game.

The Top QoE Providers Buyers Actually Use

Buyers in the lower middle market choose from roughly a dozen tier-one QoE shops. Each has a distinct sweet spot.

National accounting firms with dedicated transaction practices

• RSM US: Largest transaction advisory practice serving the middle market. Strong in industrials, healthcare services, and software. Heavy bench, deep partner involvement, and a recognizable brand name that R&W underwriters do not push back on.
• Plante Moran: Midwest-headquartered, strong in manufacturing, distribution, and family-owned business contexts. Known for partner-led engagements and high-quality writing.
• BDO USA: Global footprint with a U.S. lower-middle-market focus. Strong in international diligence and cross-border deals.
• Cherry Bekaert: Southeast-rooted with a strong government contracts and not-for-profit practice. Deep state and local tax bench.
• EisnerAmper: New York-headquartered, strong in real estate, financial services, and life sciences.
• Mazars in the US: International network with deep cross-border expertise; recently combined with FORVIS to form Forvis Mazars.
• Withum: Strong in technology, life sciences, and cannabis. Active in private-equity-backed roll-ups.
• Citrin Cooperman: Northeast and mid-Atlantic strength, with a growing national footprint and a heavy lower-middle-market PE client base.

Independent transaction advisory boutiques

• FocalPoint Partners (now part of B. Riley Securities): Independent advisory with a sharp transaction services arm, well known for deep partner attention on the lower middle market.
• Riveron: PE-portfolio-favored shop with a reputation for fast turnaround and pragmatic findings. Heavily used by sponsors for add-on diligence.

For a deeper side-by-side, see the 2026 QoE Provider Comparison, which scores each firm on partner involvement, lower-middle-market focus, R&W carrier acceptance, and average turnaround time. Buyers who want to keep the work in-house should also look at the 2026 QoE software roundup, which compares tools that automate the EBITDA rebuild for sub-$2M EBITDA targets where a full external QoE is hard to justify.

When a Buyer Should (and Should Not) Skip a Formal QoE

QoE is not free, and not every deal needs the full treatment. There are three cases where a buyer can credibly use a lighter-touch alternative.

• Sub-$1M EBITDA targets. A full QoE costs 7 to 15 percent of EBITDA at that scale. A focused financial review by the buyer’s CFO, supplemented by a tax-return-to-bank-statement reconciliation, often gets to a defensible number.
• Add-on acquisitions to an existing platform. If the platform has audited financials, a strong controller, and a clear integration plan, a focused EBITDA-quality review (without the full working capital and balance sheet workstreams) cuts cost by half.
• Asset deals at salvage value. If the buyer is paying for equipment, inventory, and a customer list at appraised value (not at a multiple of earnings), the QoE provides little incremental information; an asset appraisal and a customer reference check is enough.

In every other case, the buyer should commission a full buy-side QoE. The deals where buyers cut the QoE to save fee and then absorbed a six-figure surprise in the first ninety days post-close are the most common regret in the lower middle market. The companion piece on QoE for business sales in 2026 covers the seller-side market mechanics that make buyer-commissioned QoE non-negotiable in today’s sponsor-driven environment.

How CT Acquisitions Coordinates QoE for Our Buyer Network

CT Acquisitions sits on the buy-side as a deal-origination partner to private equity firms, family offices, and search-fund principals. We do not perform the QoE ourselves. We do three things that make the QoE more valuable for the buyer:

• Sequence the QoE provider selection to the deal profile. A $4M EBITDA HVAC roll-up add-on does not need the same firm a $22M EBITDA SaaS platform deal needs.
• Pre-screen seller financials before the QoE provider is on the clock, so the team is not paying a partner-level rate to discover what we already know.
• Coordinate with our capital partners and lenders so the QoE deliverable lands on day one of credit committee, not three weeks late.

If you are a buyer working a live deal and need a second opinion on QoE scoping or provider selection, the fastest path is to book a confidential call or use our deal intake survey to share the basics.

Frequently Asked Questions

How long does a buy-side quality of earnings engagement take?

Six to ten weeks is the realistic band for a single-entity, single-state lower middle market deal with reasonable books. Data room access lands week one, field work runs weeks two through four, the draft databook lands by week six, and weeks seven through nine handle management responses and final issuance. Deals with poor bookkeeping, multi-entity structures, or significant open items can push to twelve to fourteen weeks.

How much does a quality of earnings report cost in 2026?

Buyers should budget $25,000 to $75,000 for a single-entity buy-side QoE on a sub-$25M EBITDA target. Multi-entity, multi-state, or cross-border deals run $100,000 to $150,000. Optional workstreams (tax, IT, HR) add $15,000 to $40,000 each. The fee is a function of in-scope entities, periods reviewed, and the partner-to-staff ratio the firm proposes.

What is the difference between a QoE and an audit?

An audit is a GAAP opinion on historical financial statements: did the numbers comply with the standard. A quality of earnings report is a forward-looking diligence work product that asks a different question: what is the real, recurring, transferrable EBITDA on which a buyer can place a multiple. Audits look backward and are addressed to existing shareholders; QoE reports look forward and are addressed to the buyer with reliance rights.

Should a buyer rely on the seller’s sell-side QoE?

No. The seller’s QoE accelerates the buy-side data request and gives the buyer’s team a head start, but every mature buyer still commissions their own buy-side QoE. The two reports are written under different scopes, with different bias directions, and R&W carriers underwrite to the buy-side product.

Does QoE replace tax due diligence?

No. Tax diligence is typically a separate workstream, often performed by the same firm but with a different lead. Most tier-one providers will quote QoE and tax diligence together. Buyers in any transaction with sales-tax exposure (multi-state ecommerce, SaaS, services), state-and-local-tax nexus issues, or unresolved IRS examinations should commission tax diligence in addition to QoE, not in place of it.

Which QoE providers do R&W insurers accept without question?

The big national accounting firms (RSM, BDO, Plante Moran, EisnerAmper, Cherry Bekaert, Withum, Citrin Cooperman, Mazars) and the established independent shops (Riveron, FocalPoint) are accepted by every major R&W carrier. Smaller regional firms can also be acceptable, but the buyer should clear the firm name with the R&W broker before kicking off the engagement.

What happens if the QoE finds something material?

The buyer has four levers: retrade the price, increase the escrow and indemnity cap, negotiate a specific indemnity or holdback for the issue, or restructure the deal (more rollover, larger seller note, earnout tied to the at-risk variable). Walking is also on the table. In practice, the most common outcome is a 4 to 12 percent price retrade plus tighter language in the purchase agreement.

Can a buyer commission a QoE before signing an LOI?

Rare but possible. Most sellers will not give a buyer access to the books before exclusivity, so the QoE happens during the exclusivity period after LOI. A handful of sellers (especially those who already have a sell-side QoE in hand) will allow a buyer’s QoE provider to do limited indication work before LOI to confirm the EBITDA range is real. Even then, the full buy-side QoE happens post-LOI.
