How to Buy a Small Business: A Step-by-Step Legal Guide

To buy a small business, you typically sign a non-disclosure agreement, review the seller's financials, negotiate a letter of intent, conduct due diligence, sign a purchase agreement that defines exactly what you are buying, and then close the deal and transfer the assets. Most acquisitions are structured as asset purchases, and working with a business attorney and a CPA from the start protects you from inheriting hidden liabilities.

This article is general legal information, not legal advice. Laws vary by state and situation, and reading it does not create an attorney-client relationship. For advice about your case, talk to a licensed attorney.

Key Takeaways

• Buying a business follows a predictable sequence: NDA, letter of intent (LOI), due diligence, purchase agreement, and closing.
• Most small-business deals are asset purchases, where you buy specific assets and generally do not inherit the seller's liabilities. A stock purchase means you buy the whole entity, debts and all.
• Due diligence is the most important protective step. It verifies the seller's claims and surfaces hidden problems before you commit your money.
• The purchase agreement controls everything: price, what transfers, the seller's representations and warranties, and what happens if those statements turn out to be false.
• A buyer almost always wants a non-compete from the seller so the seller cannot reopen down the street and take the customers you just paid for.
• A business attorney and a CPA are essential. The cost of professional review is small compared with an undisclosed liability that surfaces after closing.

What "Buying a Business" Actually Means

When you buy an existing business, you are buying some combination of its tangible and intangible value: equipment, inventory, customer relationships, contracts, intellectual property, a trained workforce, and goodwill (the established reputation and customer base that make the business worth more than the sum of its parts). The legal question that shapes the entire transaction is how you acquire that value. There are two main structures.

Asset Purchase vs. Stock Purchase

In an asset purchase, you buy specific, identified assets of the business but not the legal entity itself. You and the seller list exactly which assets transfer and which liabilities, if any, you agree to assume. In a pure asset deal, the buyer generally does not inherit the seller's debts, lawsuits, or tax problems, which is why buyers usually prefer this structure.

In a stock purchase (or membership-interest purchase for an LLC), you buy the ownership of the entity itself. You step into the seller's shoes and inherit everything, including assets, contracts, licenses, and liabilities, known and unknown. Stock deals can be simpler because contracts and licenses often stay in place without needing consent to transfer, but you take on the entity's full history.

Feature	Asset Purchase	Stock Purchase
What you buy	Selected assets (equipment, inventory, IP, goodwill)	The ownership interest in the entity
Liabilities	Generally not assumed unless the agreement says so	Inherited, including unknown liabilities
Contracts and licenses	Often need consent to assign	Usually stay in place automatically
Typical buyer preference	Preferred by most buyers	Less common for small deals
Typical seller preference	Sometimes less favorable for taxes	Often preferred for tax reasons

The right structure depends on the specific business, the tax consequences for each side, and the nature of the seller's contracts and liabilities. This is a decision to make with a business attorney and a CPA, not from a template.

Step-by-Step: How to Buy a Small Business

The following sequence reflects how most small-business acquisitions proceed. Timelines vary, but the order is fairly consistent.

1. Sign a non-disclosure agreement (NDA). Before the seller hands over financial records, customer lists, or operational details, both sides sign an NDA so the sensitive information stays confidential. This protects the seller if the deal falls through and protects you if you later compete in the same space.

2. Review preliminary financials and identify fit. Look at revenue, profit, major contracts, and obvious liabilities to decide whether the business is worth pursuing. This is a high-level screen, not yet full verification.

3. Negotiate and sign a letter of intent (LOI). The LOI outlines the proposed price and structure and signals that both sides are serious. Most of an LOI is non-binding, but certain provisions are usually binding, including exclusivity (a "no-shop" promise that the seller will not negotiate with other buyers for a set period) and confidentiality. Read the LOI carefully so you know which parts bind you.

4. Conduct due diligence. This is the deep investigation that verifies what the seller has told you and uncovers what they have not. See the dedicated section below.

5. Negotiate the purchase agreement. The asset purchase agreement (or stock purchase agreement) is the definitive contract. It sets the final price and structure, lists exactly which assets transfer and which liabilities you assume, includes the seller's representations and warranties, and defines closing conditions.

6. Arrange financing and address third-party consents. If you need a loan, line up financing early, because lenders may require their own review. Identify any contracts, leases, or licenses that require a landlord's, lender's, or counterparty's consent to transfer, and start those approvals before closing.

7. Negotiate transition and a seller non-compete. Decide which employees you will keep, whether the seller will stay on temporarily to transition relationships, and the terms of a non-compete preventing the seller from competing against you.

8. Close the transaction. Execute all closing documents, including the purchase agreement, a bill of sale, assignment agreements for contracts and intellectual property, the non-compete, and any transition services agreement. Funds usually move through escrow, and any required state or local transfer filings are made.

9. Handle post-closing. Integrate the business, notify customers and vendors, transfer or apply for licenses, and watch for any indemnification claims during the agreed survival period.

Due Diligence: Where Most Deals Are Won or Lost

Due diligence is the investigation you perform before you commit. Its purpose is to confirm the business is what the seller says it is and to find undisclosed risks while you can still renegotiate or walk away. Skipping or rushing this step is one of the most expensive mistakes a buyer can make. Plan to review at least these areas:

• Financial: three to five years of financial statements and tax returns, accounts receivable aging, outstanding liabilities, and the quality of reported earnings.
• Legal: corporate records, pending or threatened litigation, all material contracts (customer, vendor, employee), intellectual property ownership, regulatory compliance, and tax filings.
• Operational: key employees and whether they will stay, customer concentration (does one client account for most of the revenue?), supplier relationships, and the condition of inventory and equipment.
• Real estate: lease terms, whether the lease can be assigned to you, and whether the landlord must consent.
• HR: existing employment agreements, non-competes from key employees, and benefits obligations.

If due diligence turns up a problem, such as a major customer about to leave, unpaid taxes, or an IP ownership gap, you can renegotiate the price, demand specific fixes or indemnities, add closing conditions, or walk away. That leverage is exactly why due diligence happens before you sign the final purchase agreement.

What Goes in the Purchase Agreement

The purchase agreement is the document that governs the deal. Pay particular attention to these provisions:

• Purchase price and structure. Is it a lump sum at closing, installments, or an earnout (part of the price paid later only if the business hits agreed financial targets)? Earnouts can bridge a disagreement over value, but they frequently cause post-closing disputes, so the targets, measurement period, and your obligations during that period must be defined precisely.
• Assets included and liabilities assumed. In an asset deal, list every category of asset transferring and state clearly that you are not assuming liabilities except those specifically named.
• Representations and warranties. These are the seller's factual statements about the business, for example that the financials are accurate, that there is no undisclosed litigation, and that the seller owns the assets free of liens. If a representation turns out to be false, you generally have a claim. The agreement also sets a survival period, the window after closing during which you can bring a claim based on those statements.
• Indemnification. This defines how the seller compensates you if a covered problem surfaces after closing, and it often ties to an escrow holdback.
• Closing conditions. These are the things that must be true or completed before either side is obligated to close, such as obtaining lender or landlord consent.

The Seller Non-Compete

In nearly every business sale, the buyer requires the seller to sign a non-compete agreement so the seller cannot open or work for a competing business for a defined period (commonly two to five years) within a defined geographic area. You are paying for goodwill, the relationships and reputation that bring customers back, and that value evaporates if the seller reopens nearby.

Non-competes in the sale-of-a-business context are generally treated more favorably by courts than employment non-competes, because the parties bargain on more equal footing and the buyer is paying directly for the goodwill being protected. Even so, enforceability still depends on state law, and some states impose strict limits. Have an attorney draft the non-compete to fit your state.

How You Will Hold the Business: Set Up Your Buyer Entity

Many buyers form a new LLC or corporation to acquire and operate the business, rather than buying it personally. Doing so keeps the liability of the acquired business separate from your personal assets and can simplify financing and taxes. If you are deciding what kind of entity to create as the buyer, our guides on how to form an LLC step by step and LLC vs. corporation walk through the choice, and the business entity tool can help you compare structures. If you form a multi-owner entity to buy the business with partners, put an operating agreement in place before you close.

Important Deadlines and Timing

Business acquisitions are not driven by statutory deadlines the way some legal matters are, but several time-sensitive items can derail a deal if missed. All of these vary by deal and by state and must be verified for your specific transaction.

• LOI exclusivity period. The no-shop window is finite. If due diligence and negotiation run long, you may need to extend it in writing before it lapses.
• Third-party consent windows. Landlords, lenders, and major contract counterparties may take weeks to approve a transfer. Start early.
• License and permit transfers. Some licenses transfer with consent; others require you to apply fresh, which can take time. Confirm whether you can legally operate on day one.
• Survival periods for representations and warranties. After closing, your right to bring a claim for a broken promise lasts only for the period stated in the agreement. Track it and act before it expires.
• Tax and bulk-sale notice requirements. Some states have bulk-sale or successor-liability rules and tax-clearance procedures with their own timing. Verify these with a CPA and attorney for the state where the business operates.

Common Mistakes Buyers Make

• Skipping or shortchanging due diligence. The single most costly error. Hidden liabilities and overstated earnings surface after you have already paid.
• Buying stock when an asset deal would protect you. A stock purchase can saddle you with the seller's unknown debts and lawsuits.
• Relying on a handshake or an unsigned LOI. Without a clear written agreement, you have little protection if the seller backs out or changes terms.
• Forgetting consents. Discovering at closing that the lease or a key customer contract cannot transfer without approval can collapse the deal.
• No seller non-compete. Paying for goodwill and then watching the seller reopen across the street.
• Using personal funds and a personal name instead of an entity. This exposes your personal assets to the acquired business's risks.
• Going without professional help. A template purchase agreement from the internet cannot evaluate your specific risks.

When to Contact a Lawyer

You should involve a business attorney from the very beginning, ideally before you sign the NDA or LOI, and certainly before any binding document. A business acquisition is among the largest financial transactions most people ever undertake, and the risks of proceeding alone are substantial. An attorney will draft and negotiate the purchase agreement, lead legal due diligence, identify risks you would likely miss, secure necessary consents, and make sure the right documents are signed at closing. A CPA is equally important for the tax and financial side. You can find vetted attorneys through our business law practice-area hub or browse the directory of business law attorneys near you.

Costs and Fees

Expect several categories of cost beyond the purchase price itself:

• Attorney fees. Business attorneys commonly charge roughly $200 to $600 per hour or more depending on region and experience, and some handle defined parts of a deal on a flat-fee basis. A full acquisition usually involves hourly work given the negotiation and due diligence involved.
• CPA and financial advisor fees for reviewing financials, structuring the deal for tax efficiency, and verifying earnings.
• Due diligence costs, which may include specialists such as an environmental consultant or an equipment appraiser depending on the business.
• Escrow, financing, and filing costs, including lender fees, escrow agent fees, and any state or local transfer filings.

These figures are general ranges that change over time and by location. Confirm fees directly with the professionals you engage. For a broader view of how legal costs fit into running a company, see our complete business law guide for small business owners.

State and Local Differences

Business sales are governed by a mix of contract law, the Uniform Commercial Code as adopted by each state, and various state and local rules. Differences that matter include:

• Bulk-sale and successor-liability rules that can make a buyer responsible for certain seller obligations, particularly unpaid sales or payroll taxes, even in an asset deal.
• Tax-clearance or "good standing" certificates that some states require before or after a sale.
• Non-compete enforceability, which ranges from broadly enforced to sharply limited depending on the state.
• License transfer rules, which differ by industry and locality.

Always verify the requirements for the specific state and locality where the business operates.

Helpful Resources

• Your state's Secretary of State for entity records, good-standing status, and filings related to the seller's business and your buyer entity.
• The IRS (IRS.gov) for the EIN you will need for your buyer entity and for guidance on the tax treatment of business acquisitions.
• The U.S. Small Business Administration (SBA.gov) for general guidance on buying a business and on financing options.
• Your state and local business licensing agencies to confirm which licenses transfer and which you must obtain.
• The USPTO (USPTO.gov) to verify trademark ownership for any brand or name included in the sale.

Frequently Asked Questions

What is the first step in buying a small business?

The usual first step is signing a non-disclosure agreement with the seller so you can review confidential financial and operational information safely. After a preliminary review, if you want to proceed you negotiate and sign a letter of intent that sets the basic terms and typically gives you an exclusivity period for due diligence. Involving a business attorney and a CPA from the start is strongly recommended.

Should I buy the assets or the stock of the business?

Most small-business buyers prefer an asset purchase because you buy only the assets you want and generally do not inherit the seller's liabilities. A stock purchase means you buy the entire entity, including its debts and any unknown liabilities, though it can keep contracts and licenses in place without consent. The best structure depends on taxes, the nature of the seller's contracts, and liability exposure, so decide with an attorney and a CPA.

Do I really need a lawyer to buy a business?

Yes. A business acquisition is one of the most significant financial transactions a person can make, and the risks of going without counsel are substantial. An attorney reviews and negotiates the purchase agreement, conducts legal due diligence, secures required consents, and ensures the proper documents are in place at closing. A CPA is just as important for the tax and financial side. The cost is small compared with an undisclosed problem that surfaces after the sale.

What is due diligence and why does it matter so much?

Due diligence is the investigation you perform before closing to verify the seller's claims and uncover hidden risks. It covers financial records, legal matters such as contracts and litigation, operations, real estate, and HR. It matters because what you learn determines whether you renegotiate the price, demand fixes or indemnities, or walk away. Finding a problem after you have paid is far worse than finding it during diligence.

What is a letter of intent, and is it binding?

A letter of intent (LOI) outlines the proposed price and structure of the deal and signals that both sides are serious. Most of an LOI is non-binding, but certain provisions, typically exclusivity (a no-shop promise) and confidentiality, are usually binding. Read the LOI carefully so you understand exactly which parts commit you before you sign.

What are representations and warranties, and what is a survival period?

Representations and warranties are the seller's factual statements about the business, such as that the financials are accurate and there is no undisclosed litigation. If one turns out to be false, you generally have a claim. The survival period is the window after closing during which you can bring such a claim. Once it expires, you usually lose the right to sue over a broken promise, so the length of the survival period is an important negotiation point.

Why does the buyer want a non-compete from the seller?

Because you are paying for goodwill, the customer relationships and reputation that make the business valuable, and that value disappears if the seller reopens a competing business nearby. A non-compete prevents the seller from competing for a defined period in a defined area. Courts generally enforce sale-of-business non-competes more readily than employment ones, but enforceability still varies by state, so have an attorney draft it for your jurisdiction.

Should I set up a new LLC or corporation to buy the business?

Many buyers form a new LLC or corporation to acquire and operate the business so that the acquired business's liabilities stay separate from their personal assets. The right entity depends on your tax goals, your financing, and whether you have co-owners. Reviewing the differences between an LLC and a corporation, and putting governance documents in place before closing if you have partners, helps you set up the right vehicle.

Buying a small business can be a smart path to ownership, but the details in the NDA, LOI, due diligence findings, and purchase agreement determine whether you get the business you think you are buying. Before you sign anything binding, talk to a licensed business law attorney in your state, and bring a CPA in alongside them, so the deal is structured to protect you.
