Owners who have never sold a company often imagine the sale as a single event: you agree on a price and the money arrives. In reality the headline number is just the opening of a process that runs for months, and a great deal of the final value is decided after the price is set, in the parts most owners never see coming.
This is a map of that process, from the letter of intent to the wire at closing, so you know what each stage is for and where deals tend to lose value.
Before the Letter of Intent: Preparation and Positioning
By the time a serious buyer is at the table, the work that determines your leverage has already happened. Clean financials, documented processes, and a clear story about why the business will keep performing after you leave all raise both the price and the certainty of closing.
This is also where a sell-side advisor earns their fee. Running a competitive process, where more than one credible buyer is engaged, is one of the few reliable ways to improve terms. A single buyer with no competition has little reason to stretch.
The Letter of Intent: Real but Mostly Non-Binding
The letter of intent, or LOI, sets out the proposed price, structure, and key terms. Most of it is non-binding, with specific exceptions such as exclusivity and confidentiality. That combination is easy to misread.
The trap is treating the LOI as the finish line. Once you sign, you usually grant the buyer a period of exclusivity, during which you cannot talk to other buyers. Your leverage is highest before you sign, because that is when competition still exists. The terms you accept in the LOI tend to define the deal, so the LOI deserves real scrutiny, not a quick signature.
- Look closely at the structure, not just the headline price.
- Understand how long exclusivity lasts and what it prevents you from doing.
- Get clarity on what is included, such as working capital and retained cash.
Due Diligence: Where Value Is Quietly Re-Negotiated
After the LOI, the buyer examines the business in detail: financials, contracts, customer concentration, legal exposure, employee matters, and more. Due diligence is the longest and most stressful stage, and it is where price often moves.
If diligence uncovers surprises, a customer who is about to leave, a contract that does not transfer, an unrecorded liability, the buyer will use them to revise terms downward. This is called a retrade, and it is far easier to prevent than to fight. The defense is preparation: knowing your own weaknesses before the buyer does and addressing them in advance.
The Purchase Agreement: The Document That Governs Everything
The definitive purchase agreement replaces the LOI as the binding contract. It contains the terms that will actually govern the sale, and several of them carry as much weight as the price.
- Representations and warranties, which are your promises about the business.
- Indemnification, which sets how much you could owe if those promises prove wrong.
- Escrow or holdback, a portion of the price held back to cover potential claims.
- Working capital adjustments, which can change the final number after closing.
- Non-compete and transition terms that bind you personally after the sale.
This is where experienced M&A counsel matters more than at any other point. The difference between standard and unfavorable terms here can be worth more than a small difference in price.
Deal Structure and Taxes: How Much You Keep
The price is not what you keep. Structure and taxes determine the net. An asset sale and a stock sale can produce very different tax outcomes for buyer and seller, and the two sides often have opposing preferences.
Earnouts, where part of the price depends on future performance, can bridge a gap in expectations but add risk and complexity. Seller financing and rollover equity have their own trade-offs. The Internal Revenue Service treats different structures very differently, so coordinating with a tax advisor before agreeing to a structure, not after, is essential.
Closing and the Period After
Closing is the day the agreement is signed and funds change hands, minus any escrow or holdback. For many owners the surprise is that the work does not end there. Transition periods, earnout measurement, and post-closing adjustments can run for a year or more.
Understanding this full arc before you start changes how you negotiate. The owners who keep the most are usually the ones who prepared early, ran a real process, scrutinized the LOI, and treated the purchase agreement as carefully as the price. A specialist sell-side advisor, matched to your industry and deal size, is the person who guides that arc, and choosing the right one is a decision worth making with care.
The Advisor Question: Broker, M&A Advisor, or Investment Bank
Who guides the sale depends largely on the size and complexity of the business, and matching the advisor to the deal is one of the earliest decisions that affects the outcome.
- A business broker typically handles smaller, often local transactions, frequently with a single buyer and a more standardized process.
- An M&A advisor or boutique investment bank typically handles larger or more complex deals, runs a competitive process across multiple buyers, and brings industry relationships that surface buyers an owner would never reach alone.
The fit matters because the wrong level of representation costs real money. A broker on a deal that warranted a competitive M&A process may leave value unrealized. An expensive bank on a small transaction adds cost without a matching benefit. The right question is which kind of guide your specific business and goals call for.
Common Ways Owners Lose Value
Most of the value lost in a sale traces back to a handful of avoidable patterns.
- Negotiating with a single buyer, which removes the competition that drives terms.
- Signing an LOI quickly, then discovering the binding details favored the buyer.
- Letting diligence surface surprises the owner could have addressed in advance.
- Agreeing to a deal structure without modeling the after-tax result first.
- Underestimating the personal commitments, such as transition periods and earnouts, that bind the owner long after closing.
None of these require bad luck. Each is a knowable risk that preparation and the right advisor can manage, which is exactly why the choice of advisor is worth treating as a decision in its own right rather than an afterthought.
