Q of E (Quality of Earnings)
A specialized accounting analysis that validates a target business's reported and adjusted EBITDA, revenue quality, and working capital — typically the primary deliverable of financial due diligence in an SMB/LMM transaction.
Full Definition
The QoE is the single most important document in LMM financial diligence. It provides independent accountant analysis of the target's earnings power, validating seller-proposed Adjusted EBITDA and identifying concerns affecting valuation or structure. Every serious LMM deal involves a QoE — either buy-side (commissioned by buyer) or sell-side (commissioned by seller to preempt questions).
How it actually works: A typical QoE covers: (1) historical financial overview — 3-year P&L, balance sheet, cash flow trends; (2) Adjusted EBITDA bridge — from reported to adjusted, with each add-back documented; (3) revenue analysis — customer concentration, recurring vs. one-time, pricing trends, churn, growth drivers; (4) margin analysis — gross margin trends, mix effects, productivity; (5) working capital — historical patterns, seasonality, normalized level, peg recommendation; (6) cash conversion — EBITDA to cash flow bridge, maintenance vs. growth CapEx, tax burden; (7) balance sheet quality — AR aging, inventory valuation, off-balance-sheet items; (8) projections support — historical basis for forward projections; (9) key findings and risks — executive summary.
Providers: Big 4 ($100-300K+), large mid-tier like Grant Thornton, BDO, RSM ($75-200K), LMM specialists ($40-100K), regional CPA firms ($30-75K). Top LMM specialists often deliver better work than large firms for SMB contexts.
Timing: buy-side QoE takes 3-6 weeks; sell-side QoE typically starts 6-12 weeks before marketing begins.
Seller vs. Buyer Perspective
Sell-side QoE before going to market is increasingly standard and usually a great investment. Benefits: find issues before buyers do, control the add-back narrative, accelerate buyer diligence by 30-60 days, signal professionalism. Cost $40-100K typically, often pays back 3-10x on a $25M deal through faster close, higher price, or fewer issues. Choose provider carefully — credibility matters.
QoE is your primary protection against overpaying and your key negotiating document. Key questions it should answer: What's reliable Adjusted EBITDA? What are the 12-24 month risks? What working capital level does the business actually need? Hidden liabilities or unusual accounting? Reliable projection base? Treat findings as basis for repricing, specific indemnities, and working capital peg negotiations.
Real-World Example
A $4.8M reported EBITDA business goes to market with sell-side QoE showing Adjusted EBITDA of $5.6M. Buy-side QoE finds: $140K of "one-time" legal fees that recurred in 3 of 4 years (rejected — reduces to $5.46M); aggressive owner comp adjustment ($420K claimed, $350K accepted based on market study); $85K pro-forma adjustment for newly added sales manager (accepted); customer contract expiring mid-LTM with $210K at risk (flagged); working capital peg analysis with 12-month average $2.3M. Final Adjusted EBITDA: $5.51M at 5.5x = $30.3M. Sell-side QoE prevented a much larger reduction — the $50K the seller spent preserved $500K+ in negotiation.
Why It Matters & Common Pitfalls
- !Credibility matters. Well-known QoE firms carry weight with buyers and lenders.
- !Add-back discipline. 60-80% of seller-proposed add-backs typically survive buy-side testing.
- !Documentation standards. Every material conclusion needs supporting evidence.
- !Scope matching risk. Simple services business needs less work than complex manufacturer.
- !Working capital analysis drives real money. Peg can swing $500K+ on mid-sized deals.
- !QoE timing. Buy-side QoE kicked off early (not late in diligence) allows follow-up time.
- !Sell-side doesn't eliminate buy-side. Even with sell-side QoE, buyers will find some issues. Goal is managing surprises, not eliminating them.

Adjusted EBITDA
EBITDA recalculated to remove one-time, non-recurring, or owner-specific expenses so buyers can see the true recurring earnings power of a business.
Add-back
An expense added to reported earnings to arrive at Adjusted EBITDA — reflecting a cost that is owner-specific, non-recurring, or otherwise wouldn't continue under new ownership.
Working Capital Adjustment
A purchase price adjustment comparing the business's working capital at closing to an agreed target (the "peg") — with any shortfall deducted from seller proceeds and any surplus added.
