The letter of intent has a public reputation and a private one. Publicly, it’s the celebrated milestone — the document with the headline number on it, the handshake in writing. Privately, among people who do deals for a living, it’s known as the document where sellers lose the most money per page, precisely because everyone has told them it’s “non-binding” and therefore not worth fighting over. Both reputations are earned. The trick is understanding how they coexist.
Start with the legal reality. Most of an LOI genuinely isn’t binding: the price, the structure, the timeline — all of it is a statement of mutual intent, walkable by either side. But a few provisions are drafted to bind, and the big one is exclusivity: your enforceable promise not to talk to any other buyer for a set period, typically 60 to 90 days. Read those two facts together and notice what the document actually does. The buyer’s obligations are intentions. Yours is a contract. They may buy your company at roughly that price; you may not speak to anyone else while they decide.
| Term | Binding? | What it pre-decides |
|---|---|---|
| Price & structure | No | The anchor every later adjustment is measured against |
| Exclusivity | Yes | Transfers leverage for its full duration — length and conditions are the real negotiation |
| Working-capital language | No | “A normal level” defers the peg fight to your weakest moment; a defined methodology settles it now |
| Escrow & indemnity markers | No | Silence today returns as the buyer’s draft in the purchase agreement |
| Financing & conditions | No | Reveals how certain the money is, and how much diligence rides on it |
| Owner employment & consulting terms | No | Left vague, they get negotiated last, when you have the least room |
| Confidentiality & non-solicit | Yes | Governs what the buyer may do with what they learn if the deal dies |
The leverage cliff
That asymmetry creates what we think of as the leverage cliff, and it’s the single most important idea in this article. The moment before you sign an LOI is the peak of your negotiating power for the entire deal: multiple buyers exist or plausibly could, the process calendar is yours, and this buyer is still competing. The moment after you sign, competition is contractually gone. Every issue that surfaces during the next ninety days — every diligence finding, every disputed add-back, every open term the LOI left vague — gets resolved in a one-buyer market, by a seller burning exclusivity days and accruing deal fatigue, negotiating with someone who knows both things.
This is why experienced advisors treat the LOI not as a preliminary document but as the last document negotiated with leverage — and push to resolve into it everything that vague drafting would otherwise defer. Ambiguity in the LOI isn’t neutral; it’s a renegotiation scheduled in advance, payable at the bottom of the cliff.
The buyer’s obligations in an LOI are intentions. Yours is a contract. Negotiate accordingly — before you sign.
The five places sellers pay for vagueness
The working capital mechanism. The classic. “Purchase price assumes a normal level of working capital” reads harmlessly and can be worth hundreds of thousands of dollars, because normal hasn’t been defined — and it will be defined later, at the cliff bottom, by a buyer’s QoE team armed with your seasonal balance sheet. Sellers who insist the LOI specify the methodology (and ideally a target range) keep that money on their side of the table.
Exclusivity’s length and conditions. Every day of exclusivity is a day of your leverage transferred to the buyer, so the period should be as short as diligence honestly requires — and it should be conditional: milestones the buyer must hit (diligence complete by X, draft agreement by Y) to keep it, so a slow-walking buyer loses the lock rather than enjoying it. An unconditional 120-day exclusivity is a gift with your signature on it.
Structure and its tax consequences. Asset sale versus stock sale usually arrives pre-typed in the buyer’s LOI as if it were boilerplate. It isn’t — the choice of structure can be the largest single economic term in the deal, and it prices completely differently before signature than after.
The shape of the consideration. “Twenty million dollars” can mean cash at close, or fourteen million cash plus a four-million earnout plus two million in rolled equity in the buyer’s entity. The LOI stage is when the mix gets negotiated — cash percentage, earnout metrics and caps, escrow size and duration, what any rolled equity actually is. Sellers who accept “details to be worked out in the purchase agreement” work them out after the cliff.
Your own exit terms. Employment or consulting period, compensation, and — quietly crucial — the scope of the non-compete you’ll sign. Five years and a wide geography versus two years and your niche is a life difference, and it’s negotiable at exactly one moment.
None of this means the LOI should balloon into a purchase agreement; deals need momentum, and over-lawyering the letter can kill enthusiasm that took months to build. The judgment — and it is judgment — is knowing which five or six terms are worth the friction because they’re unrecoverable later, and which genuinely can wait. That judgment is most of what deal advisors are for at this stage. If an LOI is in front of you now, the sequence is: model your after-tax proceeds under its structure, define the working capital mechanism, condition the exclusivity, fix the consideration mix, and only then celebrate. The celebration will keep for a week. The leverage doesn’t come back at all.

Common questions
The buyer says their LOI is “standard.” Is pushing back going to scare them off?
A buyer scared off by clarity on working capital and exclusivity conditions was planning to use the vagueness. Serious buyers expect negotiation at the LOI stage; it’s the professionalized sellers who get taken seriously.
How long should exclusivity run?
Sixty days is achievable for a prepared seller with a built data room; ninety is common. Whatever the number, tie it to buyer milestones so extensions are earned, not automatic.
Can I keep talking to other buyers “informally” during exclusivity?
No — exclusivity is one of the genuinely binding provisions, and breaching it creates real liability. Which is precisely why its terms deserve real negotiation before you grant it.
