Most sellers think signing an LOI means the deal is done. It is not. Between LOI and closing, 60 to 90 days of due diligence, legal negotiation, and psychological warfare will test every assumption you made about the buyer, the price, and your own readiness to sell. In our experience advising on $1B+ in M&A transactions, roughly 1 in 5 deals that reach LOI never close, and the ones that fail usually die from problems the seller could have prevented.
The LOI to closing process in a business sale is where leverage quietly shifts from seller to buyer. Once you sign exclusivity, you lose your ability to shop the deal. And savvy buyers know it. This guide is written from the seller’s side of the table, the perspective most M&A content ignores.
The Real Timeline: What 60-90 Days Actually Looks Like
Forget the generic “4-6 weeks” you read elsewhere. Here is what actually happens, day by day.
Every deal is different, but the pattern is remarkably consistent in the lower middle market. Here is a realistic breakdown based on deals we have advised at Livmo:
| Phase | Days | What Happens |
|---|---|---|
| LOI Signed | Day 0 | Exclusivity period starts. No-shop clause locks you in. |
| Data Room Setup | Days 1-7 | Buyer sends DD request list (often 80-150 items). You scramble. |
| Financial Due Diligence | Days 7-35 | Quality of Earnings (QoE), tax review, working capital analysis. |
| Legal Due Diligence | Days 14-45 | Contracts, IP, employee agreements, litigation review. |
| Purchase Agreement Drafts | Days 30-55 | First draft from buyer’s counsel. Rep & warranty negotiation begins. |
| Working Capital True-Up | Days 45-70 | The number that changes your final check. Disputes are common. |
| Final Negotiation & Signing | Days 60-90 | Last-minute issues, escrow terms, closing conditions resolved. |
The most dangerous period is days 30-55. The buyer has seen your financials, found every imperfection, and the purchase agreement draft arrives loaded with protections for them. This is when due diligence shifts from discovery to negotiation.
Plan for 90 days minimum from LOI to close. Anything shorter is optimistic. Anything longer means something went wrong.
The Exclusivity Trap: How Sellers Lose Leverage on Day One
The no-shop clause is the most underestimated term in the entire LOI.
Exclusivity (also called a no-shop clause) means you cannot talk to other buyers for a set period, typically 45-90 days. Most sellers accept this without negotiation. That is a mistake.
Here is why: exclusivity is the buyer’s single most powerful tool. The moment you sign it, your BATNA (Best Alternative To Negotiated Agreement) vanishes. You have no backup plan. The buyer knows this. And some buyers use the exclusivity window to deliberately slow-walk diligence, knowing that the longer you wait, the more emotionally invested you become, and the more likely you are to accept worse terms.
The typical no-shop period in lower middle market deals. Negotiate for 45-60 days maximum with a clear extension trigger, not an open-ended lock-in.
What to negotiate: cap the exclusivity at 60 days. Include milestones. If the buyer has not delivered a purchase agreement draft by day 40, exclusivity expires. Add a “hell or high water” clause requiring the buyer to use commercially reasonable efforts to close. These are standard asks. Buyers who refuse them are telling you something.
Shorter exclusivity with milestone triggers protects your leverage. Never sign open-ended no-shop clauses.
The Re-Trade: When Buyers Use Diligence to Cut Your Price
This is the risk nobody warns sellers about until it is too late.
A re-trade happens when the buyer uses findings from due diligence to renegotiate the price or terms downward. Some re-trades are legitimate: the QoE reveals that adjusted EBITDA is 15% lower than what you represented, or a key customer contract has a change-of-control clause that lets them walk. Fair enough.
But many re-trades are tactical. The buyer knew the business had warts when they signed the LOI. They just waited until you were deep in exclusivity, emotionally exhausted, and had already told your spouse the number. Then they come back with a 10-20% price cut and a list of “concerns” that conveniently add up to exactly the discount they wanted.
I have seen this pattern dozens of times. One deal nearly collapsed when the buyer’s QoE team flagged an undisclosed vendor liability, a $180,000 obligation the seller had not included in the data room. Was it material? Arguably not, relative to a $12M enterprise value. But the buyer used it as the justification for a $900,000 price reduction. Five times the actual liability. That is how re-trades work.
In another deal, a PE buyer came back at day 50 with a 12% price reduction, citing “market conditions” that had not changed since LOI signing. The seller, with our guidance, responded by pulling the exclusivity extension and reopening conversations with the second-place bidder. The original buyer closed at the original price within two weeks.
Based on patterns across Livmo’s deal experience. Sellers with competitive tension and strong advisors push back successfully in most cases.
The best defense against re-trades is a clean data room, a sell-side QoE done before the LOI, and maintaining a credible backup buyer.
Key Terms That Change Your Final Number
Four terms in the purchase agreement that most sellers do not understand until closing day.
- Working Capital Target – The buyer will set a “normal” working capital level. If your actual working capital at closing falls below it, the difference comes out of your proceeds. This number is negotiated, not fixed, and it is often where hundreds of thousands of dollars quietly change hands. Learn more in our guide to working capital adjustments.
- Rep & Warranty Scope – These are the promises you make about your business in the purchase agreement. Broader reps mean more exposure. A rep that your financials are “accurate in all material respects” is different from one that says “accurate in all respects.” That one word, “material,” can be worth millions in post-close indemnification claims.
- Escrow / Holdback – Typically 5-15% of the purchase price is held in escrow for 12-24 months as security for your reps and warranties. This is money you have earned but cannot touch. Negotiate the percentage, the duration, and the release triggers.
- Earn-Out Structure – If part of your price is contingent on future performance, understand exactly what triggers payment and who controls the business decisions that affect those triggers. We have written extensively about how earn-outs can bite sellers.
For a full glossary of M&A terms including these and more, see our M&A Glossary. Understanding the language is the first step to negotiating from strength.
The headline purchase price is not your final number. Working capital, escrow, and rep scope determine what actually hits your bank account.
How to Keep Leverage After Signing the LOI
Leverage does not disappear at LOI. But you have to actively maintain it.
Sellers who close on their terms share three habits:
1. Run your business like you are not selling. The moment your performance dips during diligence, the buyer has ammunition. Keep hitting your numbers. Keep closing new customers. A business that is performing during DD is a business the buyer cannot walk away from.
2. Respond fast but do not overreact. When the buyer’s diligence team sends questions, answer within 24-48 hours. Speed signals confidence. But do not volunteer information they did not ask for. Every extra document is a potential re-trade trigger.
3. Keep your backup warm. Even under exclusivity, you can maintain relationships with other parties. You cannot solicit offers, but you can respond if someone reaches out. And you can make sure the buyer knows, subtly, that other parties expressed interest. Competitive tension is the single greatest price protection mechanism in M&A.

Maintain business performance, respond quickly to DD requests, and preserve competitive tension, even during exclusivity.
Frequently Asked Questions
How long does it take to close after LOI?
Most lower middle market deals close 60-90 days after LOI signing. Simpler asset deals with clean financials can close in 45-60 days. Complex transactions involving regulatory approvals or multiple entities can take 120+ days. The single biggest delay factor is the seller’s data room readiness. Disorganized financials add 2-4 weeks to every deal.
Can a buyer change the price after LOI?
Yes. Most LOIs are non-binding on price and terms. Buyers can and do adjust pricing based on due diligence findings. This is called a “re-trade.” Roughly 1 in 3 deals experience some form of post-LOI price adjustment. The best protection is a sell-side QoE before LOI and maintaining competitive tension throughout the process.
What is exclusivity in an LOI?
Exclusivity (also called a “no-shop clause”) prohibits the seller from soliciting or entertaining offers from other buyers during the diligence period, typically 45-90 days. It is one of the few binding provisions in most LOIs. Sellers should negotiate the shortest reasonable window (60 days or less) with milestone-based extension triggers.
What happens during due diligence?
The buyer’s team examines every aspect of your business: financial statements, tax returns, customer contracts, employee agreements, IP ownership, legal compliance, and operational processes. Expect 80-150 individual document requests. Financial DD (often via a Quality of Earnings report) typically takes 3-4 weeks. Legal DD runs concurrently. The goal is to confirm or challenge the assumptions behind the LOI price.
