How Does Due Diligence Work After an LOI Is Signed?
Direct answer: Due diligence in an LOI contract is the buyer’s detailed review of the business over 30-90 days after signing. The process covers 50-200 document items across financials, operations, legal, tax, and HR categories. Buyers verify every claim made during initial talks. Failure at this stage triggers retrade negotiations or deal termination.
This concept connects to three frameworks in the Exit Ratio 360™ system. The SCORE Framework covers the foundational work. The SELL Framework covers how this plays into overall strategy. The THREATS Framework covers related mechanics.

Each answer runs 40-60 words with specific numbers, ranges, or timeframes for voice search and AI citation extraction. The FAQ section mirrors the FAQPage schema below for structured data alignment.
What is due diligence in an LOI contract?
Due diligence in an LOI contract is the buyer’s detailed review of the business over 30-90 days. The process covers 50-200 document items across financial, legal, operational, HR, and tax categories. Buyers verify every material claim from initial talks. Failed diligence triggers retrade or deal termination.
How long does due diligence take after an LOI?
Due diligence after an LOI typically takes 60 to 90 days for mid-market deals. Simple deals close faster at 30-45 days. Complex transactions with regulatory or environmental review can run 120+ days. The LOI exclusivity period sets the outer bound. Seller readiness is the primary speed driver.
What documents are required for due diligence?
Due diligence typically requires 50-200 documents including 3 years of tax returns, monthly financial statements, bank statements, customer contracts over $50K, employment agreements, leases, and IP filings. Service businesses need vehicle titles and maintenance records. The checklist scales with deal size and industry complexity.
What is a due diligence checklist?
A due diligence checklist is the itemized list of documents and information the buyer requires, typically 50-200 items. The list organizes requests by category with deadlines for each. Major buyers send checklists of 150+ items; individual buyers may send 30-50. Sellers upload each item to the data room.
Can a buyer lower the offer during due diligence?
A buyer can lower the offer during due diligence if the review reveals material issues. Retrade happens in roughly 25-40 percent of mid-market deals. Legitimate retrade cuts price by 5-15 percent. Tactical retrade from aggressive buyers can cut 20-40 percent. Strong seller preparation prevents most retrades.
What is retrade in M&A due diligence?
Retrade in M&A is when a buyer reduces the offer price after reviewing the business. The buyer cites specific issues like customer concentration, working capital shortfall, or undisclosed liabilities. Retrade typically cuts 10-25 percent off the original LOI price. Some buyers plan retrade from day one as tactics.
Can buyers visit my facility during due diligence?
Buyers can visit your facility during due diligence if the LOI permits it. Site visits usually happen 2-4 times during the 60-90 day period. Visits cover equipment, inventory, and operational flow. Sellers often restrict visits to after hours or weekends to limit employee awareness of the potential sale.
Can buyers interview my employees during due diligence?
Buyers can interview employees during due diligence if negotiated into the LOI. Management interviews with 3-5 key leaders typically happen in the final 30 days. Full team interviews are rare before signing. Customer interviews with 5-10 top accounts get negotiated separately. Restrict access to protect deal confidentiality.
What happens if I fail due diligence?
If you fail due diligence, the buyer either lowers offer by 10-40 percent or terminates the deal. Major failures include undisclosed debt over $100K, misstated financials, or material pending litigation. The break-up clause defines termination steps. Roughly 15-20 percent of signed LOIs die during due diligence.
How do I prepare for due diligence before selling?
You prepare for due diligence 6-12 months before going to market. Organize 3 years of clean tax returns and monthly financial statements. Build a preliminary data room with 100+ documents categorized by folder. Professional accounting review costs $5K-$15K and catches issues before buyers find them.

If you are looking to sell your business and you have an LOI contract, what is due diligence and why does it matter? This is a fantastic question. I am Scott Sylvan Bell, coming to you live from Sacramento, California, on a perfect day to talk about sales and business and a fantastic day to talk about you. Today, we are talking about letter of intent contracts and due diligence.
Let’s say you found the company that you possibly want to sell your company to, your business to, and they send you an LOI contract and they say, hey, under these terms and conditions, we are going to do due diligence. They are going to list out what they may be looking for.
So let’s just go over a few things. It could be tax statements. It could be bank statements. It could be credit card statements. It could be pay stub statements. What they are doing is they are saying, hey, you sent us over financials, you sent us over bank financials and let’s see how they correlate. Let’s see how they get together. And we started up here at ten million dollars for your company, but once we go through due diligence, we may come back and go after a cursory look, we do not really like that ten anymore, we are going to give you eight.
Some companies do this on purpose to get in, knowing they are going to beat you down on a letter of intent, knowing that they are just getting their foot in the door. They are going to give you a really super high valuation. At the end of the day, you could probably cut it in half. Is that everybody? No. I am not cynical like that. I do see people who use it.
If I am going to do an LOI and I am going to do some business with somebody, I will say, hey, listen, I need to know from the very beginning, are these offers under what circumstances? Let’s say for a minute that you offer me ten million dollars for ScottCo. Let’s say that everything is good. Are you just going to bring the numbers in to beat me up and it was a way for you to get a sneak and peek and look at my business? There is nothing wrong with asking that question. I am a huge fan of having the tough questions or the tough conversations upfront. I am a huge fan of saying, let’s get this out of the way.
Because at some point, they are going to want to do due diligence and look at the entire company as a whole. Under due diligence, they may say, we want to come by and get our eyes on your building. They may say, we want to come by after hours and look at your books. These are all things that are 100 percent normal.
If you are thinking, hey, that does not sound like it is normal. I have looked at enough letters of intent. Sometimes I will even call somebody and go, hey, if I give you a location to drive by and I send you an NDA, would you mind driving by and taking a look at this company as it sits and just kind of report out? Or can you be my eyes on the ground so I do not have to fly there and I can send a representative? It might be in the discovery that I get to take pictures. It might be that they get to interview employees. It might be in due diligence that they get to interview clients. They might get to interview suppliers. All of these terms are put in.
Sometimes I have had people come back and go, I do not want that to happen. Then we talk it through and they have got normal fears. They are worried that somebody is going to spill the beans and say the company is for sale. They cannot go out and buy their Ferrari. These are all things that are normal.
Be aware that due diligence may be pretty in depth. They may set you up with a data room. A data room is just a fancy term for a Dropbox or a place that is secured that has got better encryption. What happens is you will get a list. They will say, here is my due diligence list. It could be 50 things. It could be a hundred things. If you have a service company, it could be titles to the vehicle. If you have a physical company, it could be the lease on the land.
What they are doing is they are saying, how good are your books? How good is the information? What exactly are we buying? Here is what happens. Let me spill the beans for you. A lot of people will syndicate money in private equity. They will go to investors and say, we are looking for you to invest money anywhere from five hundred thousand to a million. We are going to guarantee on that you are going to get a rate of return of ten percent. They go to the investors and then they bundle this money. If they bundle ten million dollars, they could probably go to the bank and get a loan for a hundred million. It is a ten to one situation in most instances.
What they are saying is we did our due diligence so we could go back to the people who bought into Scott’s private equity and say that we did the right thing. That is our fiduciary responsibility. That is what we are supposed to do. I am giving you the rough outline. Due diligence for them is for them to be able to say, hey, we did what we were supposed to. We try to pick winners every time. Sometimes we pick losers. Sometimes we pick dogs. Occasionally we hit it out of the park and we hit a superstar. We are just doing our best.
Be aware occasionally there are companies out there that once they start the due diligence, that is really where the strong arm negotiation starts. You just got to know who you are getting to. You might have a breakup clause in your letter of intent contract that triggers, like I do not really want to do this with you anymore. These are all things that are up to you.
