Letter of Intent When Selling a Business: Meaning, Terms & Risks

Key Takeaways

• A letter of intent (LOI) is a preliminary, mostly non-binding document that sets the price, structure, and timeline for a sale before the final agreement.
• Its core terms include price, exclusivity, confidentiality, diligence access, and closing conditions, though only exclusivity, confidentiality, and governing law bind you at signing.
• The biggest risk is losing your negotiating leverage, because exclusivity stops you from talking to other buyers while the price can still drop in due diligence.
• Confidentiality clauses offer some protection, but if the deal falls through, sensitive information shared during diligence may already be exposed.
• For HVAC and plumbing owners, Core Growth Group offers strategy consulting before you sign an LOI and acquires qualified businesses directly as a strategic buyer. 

What Is a Letter of Intent (LOI)?

A letter of intent (LOI) is a preliminary document between a buyer and seller that outlines the proposed terms of an acquisition before a formal purchase agreement is drafted. It signals that both parties are serious about moving forward, and it is not the final contract.

Think of it as the blueprint before the building. The LOI captures the big-picture terms, meaning price, structure, timeline, and key conditions. Once both parties sign, the deal moves into due diligence and contract drafting, which is where the details get locked in.

LOIs are partially binding. Some sections carry legal weight the moment both parties sign, while others are agreed intentions that can still change. 

Most sellers do not know which is which when they first receive one, and that misunderstanding is where deals go sideways. For HVAC and plumbing owners, Core Growth Group’s high-level strategy consulting gets your financials and operations ready before an offer arrives. For qualifying companies in Texas, we also buy directly, so you negotiate with the buyer instead of a middle party.

Core Terms Found in a Letter of Intent

Every LOI is different, but the core components tend to follow a consistent structure. These are the terms that define how the transaction will be shaped, and each one deserves careful attention before signing.

Purchase Price & Payment Structure

The stated purchase price in an LOI is rarely as simple as a single number. Buyers often structure offers using a combination of cash at close, seller financing, and earnouts where a portion of the price is paid later based on future business performance. 

A headline number of $3 million might only include $2 million in guaranteed cash, with the rest contingent on results you no longer control after the sale. Sellers rarely receive 100% cash at close, and total transaction costs, including legal fees, CPAs, and any broker involved, typically run 10 to 20% of deal value. 

Due Diligence Period & Access Rights

The due diligence period gives the buyer the right to dig into your business: financials, contracts, customer lists, employees, legal history, and operations. A typical due diligence window runs 30 to 90 days, though complex transactions can extend further. 

During this time, you’ll be providing sensitive information about every aspect of your business. Access rights outlined in the LOI define exactly what the buyer can request and who they can speak with. 

Exclusivity Clause

Most of an LOI is non-binding, and exclusivity is one of the few provisions that is not.

Exclusivity, sometimes called a “no-shop” clause, prevents you from soliciting or accepting offers from other buyers for a defined period. This is one of the most consequential provisions in the entire LOI for sellers. 

Once you sign, you are legally restricted from running a competitive process, which eliminates your most powerful negotiating tool: the threat of another buyer.

Confidentiality Provisions

If you haven’t already signed a standalone Non-Disclosure Agreement (NDA) with the buyer, the LOI will typically include confidentiality language. This provision is binding and governs how both parties handle deal-related information. 

For sellers, this is critical. Your financials, customer relationships, and operational details are being shared during due diligence, and you need enforceable protections around how that information is used if the deal falls through.

Conditions That Must Be Met Before Closing

Closing conditions are the specific requirements that must be satisfied before the transaction can legally complete. Common examples include obtaining third-party consents (like landlord approval for lease assignments), securing financing, receiving regulatory clearances, and confirmation that no material adverse changes have occurred in the business. 

These aren’t formalities. If a closing condition isn’t met, the buyer can walk away from the deal entirely, even after months of work.

As a seller, you want closing conditions to be as narrow and objective as possible. Vague language like “buyer satisfaction with due diligence results” gives a buyer enormous discretion to exit the deal or use it as an upper hand to push the price down at the last moment.

Binding vs. Non-Binding Terms in an LOI

The non-binding label on most LOI terms is often misread as meaning those terms don’t matter yet. That’s a costly misunderstanding. 

Even though the purchase price isn’t legally enforceable at the LOI stage, anchoring the number in writing creates a practical baseline. Buyers will reference that figure throughout due diligence, and pushing back on it later becomes significantly harder.

The binding provisions, on the other hand, take effect the moment both parties sign. Exclusivity, confidentiality, and governing law are enforceable contract terms. Violating an exclusivity provision, for example, could expose you to legal liability even if the overall deal never closes.

Here’s which provisions are typically binding and which remain open to negotiation: 

LOI Provision	Typically Binding?	Why It Matters
Purchase Price	Non-Binding	Can be renegotiated after due diligence
Exclusivity / No-Shop Clause	Binding	Legally prevents you from talking to other buyers
Confidentiality Provisions	Binding	Protects sensitive business information shared during diligence
Deal Structure (Asset vs Stock)	Non-Binding	Can shift before the final agreement
Due Diligence Timeline	Non-Binding	Often extended by mutual agreement
Governing Law / Dispute Resolution	Binding	Determines legal jurisdiction if conflict arises
Closing Conditions	Non-Binding	Finalized in the definitive purchase agreement

 

Risks of Signing a Letter of Intent

Losing Negotiating Leverage After Signing

Before you sign an LOI, you hold the stronger position. The buyer wants what you have, and you haven’t committed to anything. 

The moment you sign, the situation shifts considerably. You’re now invested in the process: you’ve taken your business off the market, you’ve started preparing due diligence materials, and your team may already know a deal is in progress. 

Walking away becomes emotionally and operationally costly, and experienced buyers know this.

Exclusivity Locking You Out of Other Buyers

Exclusivity is the provision that most directly eliminates your negotiating power after signing. A 60-day exclusive period means that even if a better buyer emerges, one offering more money or a faster close, you are legally prohibited from engaging with them.

If the original buyer slows down due diligence or reopens the price during that window, you have no competitive pressure to counter with. Negotiate the shortest exclusivity window possible, and push for clear language on what happens if the buyer fails to meet their own milestones during that period.

Buyer Using Due Diligence to Renegotiate Price

This is one of the most common changes sellers experience, and one of the most frustrating. A buyer agrees to a price in the LOI, then uses due diligence to identify issues that justify a reduction.

The best defense is a clean, well-organized data room and thorough preparation before due diligence begins. Buyers renegotiate most successfully when they find surprises. 

If your financials are airtight, your contracts are organized, and there are no material undisclosed issues, you remove most of what they would use to push the price down.

Confidential Business Information Exposure

Due diligence requires you to hand over deeply sensitive information. If the deal falls through, that information is now in the hands of someone who may be a competitor, may share it with others in your industry, or may use it to approach your customers directly. 

Core Growth Group Reviews Your LOI Before You Sign

A letter of intent is the most consequential document you sign before the purchase agreement, and the one most sellers spend the least time examining. It sets the price anchor, locks you into exclusivity, opens your business to diligence, and frames everything that follows. Getting the LOI right is about entering that stage on terms you understand.

Core Growth Group is a strategic acquirer of plumbing and HVAC companies in Texas, and we offer high-level strategy consulting for owners getting ready to sell. This kind of LOI preparation starts in our Prepare process, with financial cleanup, documented systems, and stress testing done months before a buyer sends you anything, and it carries into Exit once you are negotiating the LOI itself. Get in touch while there is still time to do it. 

Frequently Asked Questions (FAQs)

Is a letter of intent legally binding when selling a business?

An LOI is partially binding. Most substantive deal terms, including the purchase price, deal structure, and closing conditions, are non-binding and can change before the final agreement. Specific provisions are enforceable from signing, usually exclusivity, confidentiality, and governing law, and an attorney should identify which sections apply before you sign.

Can a buyer walk out after signing an LOI?

Yes, since most LOI terms are non-binding. Without a binding deposit or break-up fee, a buyer faces little financial consequence for exiting. Pushing for a break-up fee or earnest money gives you some protection if a buyer walks after an extended diligence process.

How long is a letter of intent valid?

Most LOIs include an expiration date, typically 30 to 90 days from signing, depending on deal complexity. Both parties can agree in writing to extend it. Be cautious about repeated extensions without meaningful progress, since a long timeline drains resources and keeps your business off the market.

Do I need a lawyer to draft a letter of intent for a business sale?

You do not legally need one to sign an LOI, though having an attorney review it beforehand is strongly advisable. The binding provisions carry legal obligations, and the non-binding terms still frame the purchase agreement that follows. An experienced transaction attorney can identify problematic language and make sure you understand what you are agreeing to.
