The owner had already told his wife. That’s the detail that stays with you in these situations — the LOI was signed at a number he’d been dreaming about for a decade, the buyer was enthusiastic, and in his mind the business was sold. He’d started, quietly, to say goodbye to it. Fourteen weeks later the buyer walked, and the hardest part wasn’t the money. It was that nothing dramatic had happened. No scandal, no fraud, no market crash. The deal simply eroded, one small disappointment at a time, until one Tuesday there wasn’t enough of it left.
We tell sellers this story — a composite, but a faithful one — because it corrects the single most dangerous belief in the sale process: that signing the LOI means the hard part is over. It means the opposite. The LOI is the starting gun. Industry veterans will tell you that a meaningful share of signed deals never close, and here’s the part that should change how you prepare: the deals that die between LOI and close almost never die from one big thing. They die from accumulation.
How a deal actually erodes
Understand the buyer’s psychology on signing day: they’re at peak enthusiasm and minimum information. They’ve priced the business off your presentation of it — the story, the summary financials, a few management meetings. Everything that happens next is the collision of that story with the underlying records, and every small mismatch withdraws from an account you can’t see the balance of.
The diligence findings come first, and the biggest of them is the quality of earnings analysis that tests whether your EBITDA survives scrutiny. But it’s rarely the QoE alone. It’s the QoE finding plus the customer contract that turns out to be unsigned, plus the receivable that’s actually 140 days old, plus the answer that took three weeks to produce. None of these kills the deal. Each one whispers the same question to the buyer: what else don’t I know?
Then time does its work. Every week a deal stays open, it’s exposed — to a soft quarter (nothing reprices a deal faster than missing your own forecast during diligence), to a lender getting nervous, to a key employee resigning, to the buyer’s board finding a more attractive target. Slow document production doesn’t just delay the close; it extends the window in which everything else can go wrong. Deal fatigue is real, and it compounds: somewhere around week sixteen of an unplanned twenty-six-week process, both sides start negotiating angry, and small issues that would have been Tuesday phone calls in week six become matters of principle.
And underneath it all sits the seller’s most common unforced error: running the deal instead of the business. Diligence is a second full-time job. Owners who take it on personally — every data request, every call — inevitably let the P&L slip. Then the slipping P&L becomes the buyer’s newest finding, and the erosion accelerates. The business’s job during diligence is to hit its numbers. Someone else has to carry the deal.
Deals rarely die of one wound. They bleed out from a dozen small cuts, most of them self-inflicted.
What the sellers who close do differently
The pattern among sellers who make it to the wire transfer is boring, and that’s the point: they made the diligence period uneventful. In practice, that reduces to four disciplines.
They pre-diligenced themselves. Everything a buyer’s team will examine — earnings quality, customer contracts, receivables aging, litigation, licenses, the cap table — got examined first by their own advisors, months earlier. Findings were fixed or framed before a buyer existed to find them. This is the logic of the sell-side QoE, extended across the whole company: the surprises still happen, but they happen privately, on your calendar.
They negotiated the LOI like it mattered — because it does. The LOI is mostly non-binding, which sellers hear as “mostly doesn’t matter.” That is the wrong conclusion. It’s the high-water mark of your leverage; once you sign and grant exclusivity, competition disappears and every open item gets resolved in a one-buyer market. The working capital mechanism, the exclusivity period’s length, what happens to the deposit, which diligence gates exist — vague LOI language on any of these is a future renegotiation scheduled in advance.
They staffed the deal. A data room built before it was needed. A named person — advisor, CFO, deal counsel — owning every request with a 48-hour response standard. The owner’s calendar protected for the actual business, so the company hit its forecast while being sold. Buyers read fast, organized responses as competence, and competence sustains the price.
They kept the timeline short and the momentum visible. Ninety days from LOI to close is at the fast end of normal; drift toward two hundred days is where deals come apart. Every week shaved off the schedule is a week the world can’t intervene.
None of this is glamorous. All of it is doable — and nearly all of it happens before the LOI is signed, which is exactly when most sellers think the work hasn’t started yet.
If you’re heading to market in the next year, the preparation window is now: self-diligence, data room, forecast you can actually hit. If an LOI is already in hand, the priorities compress to three — respond fast, run the business, and never miss a number you gave the buyer. The sellers who close aren’t the lucky ones. They’re the ones who understood, early, that a signed LOI is a race that hasn’t started yet.

Common questions
What share of signed deals actually close?
Estimates vary by market and deal size, and we’re wary of false precision — but practitioners broadly agree the failure rate between LOI and close is substantial, not rare. The planning assumption that matters: your deal is not safe at signing.
How long should LOI-to-close take?
Well-prepared middle-market deals commonly close in 90 to 120 days. Past six months, the odds turn against you — not because of any single deadline, but because exposure to bad luck accumulates weekly.
Can I negotiate protections into the LOI?
Yes, and you should — exclusivity limits, timeline milestones, and clear working capital language chief among them. It’s the last document you’ll negotiate with competitive leverage.
Should I tell employees the business is being sold?
Generally, the circle stays as small as possible until close — typically the few people needed to produce diligence materials, under confidentiality. A leaked deal that later collapses damages the business twice.
