Quality of Earnings Analysis: A Practical Guide for Buyers

If you're buying a small or lower-middle-market business, the single document that will save you the most money — or stop you from buying the wrong company — is a Quality of Earnings analysis (QoE). And yet most first-time acquirers either skip it, mistake it for an audit, or accept the seller's broker book at face value.

This guide is the plain-English version: what a QoE is, what it contains, how to read one, and where the real risk hides.

What a Quality of Earnings analysis actually is

A QoE is an investigative financial analysis whose job is to answer one question: is the earnings number this seller is showing me real, sustainable, and transferable to me as the new owner?

It is not an audit. An audit asks "do the financial statements comply with GAAP?" A QoE asks "if I strip out one-time items, owner perks, accounting choices, and non-recurring revenue, what does this business actually earn in a normal year?"

That number — adjusted EBITDA (or SDE for very small deals) — is what your purchase price multiple is built on. Get it wrong by 15% and you can easily overpay by 30–60% of the equity check.

What's inside a QoE report

• Proof of cash — tying reported revenue and expenses to bank statements.
• Revenue quality — customer concentration, recurring vs. one-time, churn, pricing.
• Normalized / adjusted EBITDA — a detailed bridge from reported earnings to a defensible run-rate number.
• Working capital analysis — what's a "normal" level the buyer should expect to fund at close.
• Net debt and debt-like items — deferred revenue, customer deposits, accrued PTO, capital leases.
• Quality of the balance sheet — stale AR, obsolete inventory, capex that was expensed.

The add-back fight is where deals are won and lost

Almost every seller comes to the table with a list of "add-backs" — expenses they argue you shouldn't count because they won't continue post-close. A good QoE separates them into three buckets:

1. Legitimate — owner's above-market salary, one-time legal fees, a one-time office move.
2. Defensible but debatable — owner's car, "consulting fees" paid to a family member, a discretionary marketing experiment.
3. Aggressive or false — recurring software the business genuinely needs, marketing spend that drives the revenue you're buying, an "underperforming" employee whose work still has to get done.

The bucket each item lands in is rarely obvious from a spreadsheet — it requires reading invoices, asking follow-up questions, and understanding the business. This is the bulk of QoE work.

How to read a QoE you've been handed

Open the executive summary, then jump straight to four things:

1. The EBITDA bridge. Every add-back, by category, by year. Anything >5% of EBITDA deserves a question.
2. Revenue trend by month, not by year. Annual numbers hide a business that fell off a cliff in Q4.
3. Customer concentration table. Top 10 customers as a % of revenue, and how that's changed.
4. Working capital "peg". The number the seller has to leave in the business at close. A missing or low peg is a hidden price increase you'll feel on day one.

When you actually need one

Rule of thumb: if the deal is over ~$1M in enterprise value, get a QoE. Below that, the math sometimes doesn't work for a $20k–$50k firm engagement — which is exactly the gap TrueEBITDA was built for.

The fast path

Traditionally a QoE takes 3–6 weeks and runs $20k–$80k. For most searchers and SMB buyers, that's a meaningful chunk of the equity check and slows every deal down. With TrueEBITDA you upload the target's financials, answer a structured set of questions about the business and the add-backs, and get a defensible Quality of Earnings analysis in about 10 minutes — at a price that makes sense to run on every LOI, not just the one you're already convinced about.
