Know What the Buyer Already Knows
Every buyer's diligence team walks into your process with a framework they've already run on dozens of comparable transactions. They know where the revenue recognition issues are in your industry. They know what the working capital seasonality pattern looks like. They know which add-backs break down under documentation scrutiny. You have not run this analysis before. They have.
Exit diligence is the practice of running the buyer's analysis on your own company before the buyer does — so that when the QofE team arrives, you've already found what they'll find. And you've either fixed it, documented it, or built the narrative for it on your terms.
The founder signs the LOI for $128M. The closing dinner is for $123.8M. The buyer's attorney calls the difference a working capital adjustment. The founder calls it a $4.2 million retrade. The working capital model that produced it had been running for three weeks before the founder knew it existed.
The QofE adjustment, the working capital peg gap, the undocumented add-back, the change-of-control clause nobody read — none of these are surprises to the buyer. They are standard findings. What surprises the buyer is the seller who has already found them, addressed them, and documented the response. That seller is rare. This book produces that seller.
"The accounting policy you set today, in less than thirty seconds, at a desk on a Tuesday morning, is the negotiation that happens three years from now."
— Exit Diligence, Chapter 1
These figures are drawn from real transaction patterns across 100+ middle-market deals. The gaps are not anomalies. They are the median outcome for the unprepared seller.
Working Capital Erosion
The gap between a seller's expected working capital peg and the buyer's calculated peg, measured as a percentage of enterprise value. On a $75M deal, that's $2.25M to $5.25M — dollar for dollar off the wire.
Add-Back Acceptance Without Documentation
The acceptance rate for officer compensation add-backs when no market survey, no board resolution, and no contemporaneous documentation exists. With documentation: 80–90%.
Cost of 18 Months of Preparation
The all-in advisor cost for a full preparation program — fractional CFO, sell-side QofE, M&A counsel, SALT, technology, and employment counsel — for a $30–75M enterprise value business.
Documented Return on That Preparation
The conservative estimated benefit captured by the prepared seller in Case Study One: QofE accepted nearly in full, working capital peg negotiated at seller's proposed level, closing adjustment of $140K on a $46.4M deal.
Median Diligence Timeline, Prepared Seller
A complete data room on day one, a sell-side QofE in the VDR, and 24-hour response discipline consistently compresses the diligence timeline by 4–6 weeks versus the unprepared seller.
The Cost of Not Preparing
The gap between a $55M LOI and $42.9M in net proceeds for the seller in Case Study Three. QofE adjustment, working capital gap, reduced add-back acceptance, tax escrow, and closing adjustment — each preventable.
Organized in the same sequence a buyer's diligence team uses. Each chapter addresses one operational question the buyer will ask — and that you should have answered before they arrive.
The Deal That Was Already Over
The founder who signed at $128M and wired at $123.8M. What the working capital model the buyer had been running for three weeks actually contained.
The Transaction Lens
The five accounting decisions made in under thirty seconds that become negotiations three years later. Revenue recognition, customer deposits, capitalization thresholds, inventory, officer compensation.
What the QofE Actually Finds
All seven categories of QofE adjustments — how each works, what the buyer's analyst is measuring, and how to run the analysis on yourself before the buyer does.
Revenue Recognition: The First Place Buyers Look
Cutoff testing, pattern analysis, customer quality, recognition policy consistency. What a prepared revenue file looks like versus what the buyer finds in a standard data room.
The Add-Back Playbook
Documentation standards for all 20 add-back categories. Four deal narratives: the one that saved $800K, the one that disappeared in week two, the partial victory, and the clean file.
Working Capital: The Negotiation Nobody Prepares For
The six line items that become the negotiation. The peg mechanism. The 18-month optimization strategy that moves the peg in the seller's favor before the process begins.
The EBITDA Bridge as a Credibility Signal
The five-step bridge structure, the five credibility characteristics, and why the bridge the buyer can reconcile in five steps is the bridge that makes the buyer trust everything else.
Cap Table Hygiene Before It Is Anyone Else's Problem
Six categories of equity issues that delay closings. The equity audit process. Why this cleanup is cheap and unglamorous eighteen months out, and expensive and dangerous six weeks out.
The Management Presentation
The six-section structure that answers what buyers are actually evaluating. The three-rehearsal process. Why the seller who presents risks proactively is the seller the buyer believes about everything else.
Building the Data Room Before the Process Exists
The running data room strategy. All eleven categories — what buyers look for in each. The document that was created eighteen months before the process versus the document created in response to the checklist.
HR Infrastructure: The Diligence Nobody Talks About
Contractor misclassification. Pay equity analysis. Wage and hour compliance. The HR audit process that most sellers have never conducted before the buyer's team arrives.
IT, Cyber, and the Systems Audit
Four technology diligence categories. Why ransomware changed buyer expectations permanently. The NIST framework maturity standard. Data privacy and IP ownership chain of title.
Customer Contract Risk
Change-of-control provisions, assignment restrictions, exclusivity, termination-for-convenience. The contract review and remediation process. What a proactive contract risk matrix accomplishes in the process.
Tax Exposure and the Pre-Sale Cleanup
Sales tax nexus and the VDA strategy. Uncertain income tax positions. Payroll tax compliance. The sequencing framework: highest dollar first, longest resolution timeline first, cleanest closure first.
Environmental, Regulatory, and Licensing Risk
Phase I and Phase II assessments. Operating license change-of-control restrictions. Why the seller who commissions the Phase I controls the timing, the consultant, and the initial framing of every finding.
Representations and Warranties Insurance
How RWI works, what the underwriting process examines, and the five most common specific exclusions. Why RWI covers surprises, not known problems — and how preparation limits the exclusions.
The Sell-Side QofE: Running the Buyer's Analysis First
Five things a sell-side QofE accomplishes that no other pre-sale tool can. Provider selection. Scope. Why the seller who has a signed sell-side QofE in the data room on day one is playing a different game.
Seller Negotiating Leverage: How to Keep It
Pre-LOI leverage, the peg anchor, information advantage in the diligence period, the purchase agreement offense, clean closing conditions. Why leverage is a function of preparation, not deal skill at the table.
The Post-LOI Phase: Protecting Yourself After You Sign
The anatomy of the retrade. Six mechanisms of post-LOI price erosion. The corresponding protection for each. Why the exclusivity period is where the preparation is tested, not where it is built.
The Interlude: What the Process Does to the Founder
The attention tax. The confidentiality problem. The emotional register of selling something you built. This chapter contains no framework. It contains an honest description of the fourteen weeks.
The 18-Month Readiness Roadmap
Month-by-month detail. The advisor coordination problem and the master issues register. Why Month 4 is the most important month and what changes if you miss it.
The 30-Day Pre-Process Sprint
Three worked scenarios: the unsolicited strategic approach, the PE-backed exit with six weeks notice, and the interrupted preparation. The triage that determines which thirty days of work produces the most value.
"Seller leverage in M&A is not a function of deal skill at the table. It is a function of preparation before the table is set."
— Exit Diligence, Chapter 17
You have built something real and you intend to close at a number that reflects it. This book gives you the buyer's framework, month by month, so that when the QofE team arrives, nothing they find will be a surprise — to either of you.
You need to know what the buyer's analyst will find before they find it. The working capital model, the add-back package, the accounting policy documentation — this book is the technical manual for all of it, written by someone who has sat on both sides of the table.
The institutional infrastructure of a PE-backed company often produces false confidence about diligence readiness. This book covers the categories — HR, technology, tax nexus, contract risk — that even well-resourced finance teams consistently underestimate.
This is the book you hand to the founder at the initial engagement call, eighteen months before the process. It reduces the data room assembly burden, produces more defensible add-back claims, and shortens the diligence timeline. It makes your job easier.
Not supplementary material. Working reference tools you will open in the process.
