A letter of intent, often called an LOI, is the short document that turns a conversation about buying a business into a real negotiation. It states the price range, the structure, and the key conditions, so both sides know whether a deal is worth pursuing before paying lawyers to draft a full agreement. Done well, it saves weeks of wasted effort.

The first thing to understand is that most of an LOI is not legally binding. The price, structure, and timeline are usually expressions of intent, not commitments. The parts that are binding tend to be confidentiality, exclusivity, and governing law, and those should be marked clearly so neither side is confused about what they have promised.

Start with the basics: the names of buyer and seller, a description of the assets being bought, and the proposed price or price range. Be specific about what is included, such as the domain, code, customer data, social accounts, and brand assets, because arguments about what was included are a common source of failed deals.

State the deal structure plainly. Say whether it is an asset purchase, how much is paid at closing, and how much is deferred through seller financing or an earnout. If part of the price depends on future revenue, spell out the metric, the measurement period, and who calculates it, because vague earnouts cause more disputes than any other clause.

Exclusivity, sometimes called a no-shop clause, deserves your attention as a buyer. It asks the seller not to negotiate with other buyers for a set period, usually 30 to 60 days, while you complete diligence. Without it, you can spend weeks checking a business only to lose it to a faster bidder at the last moment.

Diligence access should be written into the LOI as well. List the materials you need: financial statements, payment processor records, traffic analytics, customer data in anonymised form, code access under NDA, and key contracts. Setting this expectation early avoids the slow drip of documents that stalls many small deals.

Include the transition support you expect from the seller. State how long they will help after closing, how many hours per week, and what that help covers, such as introducing you to key customers or walking you through the systems. Sellers who agree to a clear transition in the LOI rarely argue about it later.

Non-compete and non-solicitation terms belong in the LOI conversation, even if the full wording comes later. Ask the seller to agree in principle not to start a competing business or poach customers for a defined period. If a seller refuses this outright, you need to know before you invest in diligence, not after.

Set a realistic timeline with dates, not just good intentions. Diligence period, target date for the purchase agreement, and target closing date all help both sides plan. Deals without dates drift, and drifting deals are where sellers find other buyers and buyers lose enthusiasm.

Be careful about what you leave out. An LOI that ignores working capital, inventory, or existing liabilities can create a nasty surprise at closing. Even a simple line stating that the price assumes no debt and no undisclosed liabilities protects you and forces the seller to disclose problems early.

Keep the LOI short enough to sign quickly but complete enough to prevent misunderstandings. Two to four pages is plenty for most micro-acquisitions. If the document grows longer than the eventual purchase agreement, you have probably started negotiating the wrong document.

Finally, remember the LOI is a filter, not a finish line. Its job is to confirm that buyer and seller agree on price, structure, and key terms before anyone spends serious money. If you cannot agree on the LOI, you almost certainly cannot agree on the full deal, and learning that early is a success, not a failure.

Treat the letter of intent as the moment a casual conversation becomes a professional negotiation. Write it clearly, insist on the clauses that protect your time and money, and use it to test whether the seller is serious before you commit to the full cost of buying.
