Operational & Commercial Due Diligence

The operator read. The half a QoE was never built to cover.

A Quality of Earnings proves the earnings were real. The operator read proves they survive new ownership: owner dependency, concentration, bench depth, systems, revenue durability, and calls to the customers themselves.

The Gap

A clean report proves the profit was real last year. It cannot prove it survives the day you take over.

A Quality of Earnings tells you the earnings were real. It is historical by design, and that is not a flaw: it is the job. But a buyer is not buying last year. They are buying next year, from a seller who is leaving.

The operator read is the second half of that question. It is a defined scope of eight workstreams, run by an operator who has sat in the seat, and on a lower-middle-market deal it is usually where the finding that changes the price actually comes from.

It is not a market study and it is not a customer survey. It is a structured read of whether this business, without this owner, still works.

What A QoE Will Not Tell You

Six things a financial scope is not built to answer.

Buy-Side Diligence · The Customer Call

The financials tell you what happened. The customers tell you whether it happens again.

On a lower-middle-market deal the risk is usually a handful of accounts, and whether they were buying the business or buying the owner. That does not show up in the general ledger, so we run the customer work inside the same scope as the numbers.

01 Concentration map Revenue ranked by customer, three years, margin by account. Churn and new-logo history. 02 Sample selection Top accounts, plus the risky ones: falling volume, odd margin, no contract. 03 Structured calls Same question set every time. Run by us, not the buyer, so the answers are not managed. 04 Into the same report Findings sit beside the earnings work, not a separate deliverable nobody reads. What the call actually tests Were they buying the business, or the owner? The single question a financial-only scope cannot answer. Renewal intent, and what switching would cost them Stated intent, not inferred from a revenue line. Price sensitivity and margin durability Whether the margin survives a new owner and a price test. Contract reality versus handshake What is on paper, what is habit, and what walks. What it changes on the deal Price A concentration finding reprices the deal before close, not after. Structure Earnout tied to retention of the accounts that actually matter. Protection Reps, escrow and covenants written around a named risk. A buyer cannot run these calls and stay objective. That is the reason to have someone independent do them.

Whether the relationship transfers

A QoE can flag that one customer is 30% of revenue. It cannot tell you whether that customer stays when the person they actually buy from walks out the door.

Whether the business runs without the seller

Licences, know-how, the supplier who gives them terms as a favour. Some of it is documented. Most of it is in one person's head.

Misclassification inside a clean tie-out

Proof of cash proves the totals reconcile. It does not prove the costs sit in the right place, and margin by line can be materially wrong while the total is right.

Deferred maintenance dressed as profit

An add-back that removes a cost the business will absolutely incur again is not an add-back. It is a future liability, priced today as earnings.

Seasonal working capital

A trailing average computed in the slow season sets a peg that leaves the buyer short of cash in the busy one.

Whether a lender will actually fund it

Debt service is calculated independently of the QoE. A clean report and a declined loan are entirely compatible outcomes.

The Scope

Eight workstreams, two of them deliberately bounded.

WorkstreamWhat it produces
Owner dependency & key-person riskA dependency rating with evidence behind it, the seats map, and the transition risk named rather than implied.
Concentration, deepThe concentration exhibit and a revenue-at-risk figure with its assumptions stated.
Management & bench depthA bench-depth read, single points of failure named, retention exposure.
Systems, process & cadenceSystems maturity, the documentation gap list, and whether the operating cadence exists at all.
Revenue durabilityThe recurring-revenue claim tested rather than accepted.
Customer reference calls
Buy-side only, up to six
A reference-call log, themes synthesised. Never attributed to a named customer in the report without consent.
Market & competitive read
Bounded: a named competitor set plus desk research
The competitor set, a structural read, named risks. This is not primary market research and the scope fence says so.
Forward action planWhat to do in the first ninety days, written to be useful after the deal rather than only during it.

Scoped to the deal. Runs standalone or alongside a Quality of Earnings, which is how most buyers take it.

Two Tools We Use

The Kill List, and the add-back test.

The Kill List. Before anyone spends money on diligence, write down the measurable things that would end the deal, ranked. Any customer over 30%. Cash flow 20% below the projection. Cannot operate without the seller. Then diligence tests the list instead of wandering.

The add-back test. Every adjustment clears three gates or it comes off: a source document, a credible reason it will not recur, and a market benchmark showing it was abnormal. An add-back has to make the number honest, not just bigger.

At roughly four times earnings, every unsupported dollar of add-back is about four dollars of price. That is why we show you the adjustments we rejected, not only the ones we allowed.

Capacity, Stated Plainly

Two operational engagements at a time. That is a published lead time, not a secret.

The interviews and the verdict are done personally, so the operational work is capacity-constrained by design. Red-Flag screens do not count against it. If the calendar is full we will tell you the date rather than take the work and be late.

Where To Next

The next useful thing, depending on where you are.

The Method

What we actually ask a customer, and why they answer.

Coming Soon · About 6 Minutes

Six calls, a script built to avoid leading the witness, and what we do with the answers.

Reference calls are buy-side only, and never attributed to a named customer without consent.

The report tells you the profit was real. We tell you whether it is still yours a year from now.

Tell us the deal and we will tell you which scope fits, usually within one business day.
