Selling a Small Business in the US: Legal Documents

Selling a small business can stall quickly when the buyer asks for documents you cannot produce. Owners often focus on price first, then discover the brand was never properly assigned, customer contracts cannot be transferred, or a key supplier agreement ends if control changes.

The best time to fix those issues is before a buyer starts diligence. A clean set of business sale documents helps you protect confidential information, control negotiations, answer buyer questions, and avoid giving the buyer a reason to reduce the price.

You should be able to decide which documents are needed to sell a business, what to clean up before diligence, and which legal issues usually belong in the letter of intent, purchase agreement, and closing documents.

Business Sale Document Checklist for Owners

A strong sell a business checklist starts with the documents that prove what the buyer is actually getting, who owns it, and whether it can be transferred.

Most small business sales are structured as either an asset sale or an equity sale. In an asset sale, the buyer usually purchases selected assets, such as goodwill, equipment, inventory, domain names, contracts, and intellectual property. In an equity sale, the buyer purchases the ownership interests in the entity, so the entity continues to own the business assets and remains party to its contracts.

That distinction drives the documents needed to sell a business. An asset sale usually needs more assignment documents because assets and contracts are moving from seller to buyer. An equity sale usually focuses more heavily on company records, ownership approvals, liabilities, and change of control provisions.

Owners should prepare a diligence folder that includes:

• Entity records: formation documents, amendments, current ownership records, board or owner approvals, assumed name filings, and evidence that the business is in good standing with the state where it was formed.
• Financial and operational records: profit and loss reports, balance sheets, accounts receivable and payable records, inventory records, equipment lists, permits, insurance policies, and key performance metrics.
• Customer and supplier contracts: signed agreements, order forms, terms of service, statements of work, franchise or distribution documents, termination rights, assignment clauses, and any side letters.
• Employment and contractor documents: offer letters, employment agreements, contractor agreements, confidentiality agreements, invention assignment provisions, handbooks, and employee benefit documents.
• Intellectual property records: trademark filings and registrations, copyright registrations, domain name records, software development agreements, design files, license agreements, and a founders agreement or other proof that founders, employees, and contractors assigned IP to the business.
• Privacy and digital compliance documents: privacy policy, cookie or tracking disclosures, data processing contracts, vendor security terms, customer consent records, and records of any data incidents.
• Real estate and equipment records: commercial lease, landlord notices, consent requirements, equipment leases, vehicle records, security interests, and maintenance documents.
• Compliance documents: business licenses, professional permits, regulatory correspondence, advertising substantiation, product claims support, and industry specific approvals.

A buyer will use these documents to test the value and risk of the business. For example, a buyer paying a premium for recurring revenue will want to know whether the customer contracts can be assigned, whether customers can terminate on short notice, and whether the seller has made promises outside the written terms.

The same applies to businesses built around a brand, app, online store, or proprietary process. A trademark registration, domain account, copyright ownership trail, and clean contractor invention assignment can make the difference between a straightforward diligence process and a price renegotiation.

State law, industry rules, and contract terms can change the answer on approvals, transfer mechanics, licenses, employment obligations, and notices. You do not need a state by state memo to start preparing, but you do need to identify where your documents depend on state law or third party consent.

Use an LOI and Confidentiality Agreement Carefully

A letter of intent and a confidentiality agreement let you discuss a sale without handing the buyer unlimited leverage or unrestricted access to sensitive business information.

The letter of intent for a business sale, often called an LOI, usually records the headline deal terms before the full purchase agreement is drafted. It can cover price, structure, assets included, liabilities excluded, payment timing, diligence access, exclusivity, confidentiality, transition plans, and the target closing timeline.

Owners sometimes sign an LOI because it is described as nonbinding. That label can be misleading. Many LOIs make most deal points nonbinding, while making confidentiality, exclusivity, expenses, governing law, and dispute provisions binding. If the LOI gives the buyer exclusive negotiation rights for too long, the seller may be unable to talk to other bidders while the buyer slowly searches for reasons to lower the price.

A practical LOI should usually address:

• Deal structure: whether the parties expect an asset sale, equity sale, merger, or another structure.
• Purchase price: the headline price, any earnout, seller note, holdback, working capital adjustment, inventory valuation, or escrow concept.
• Included and excluded assets: customer lists, equipment, inventory, brand assets, software, websites, social media accounts, contracts, cash, accounts receivable, and personal assets used in the business.
• Assumed and excluded liabilities: whether the buyer will take on specific liabilities, and which debts, taxes, refunds, disputes, or other obligations remain with the seller.
• Diligence process: what the buyer can review, when access begins, who can see information, and how employees, customers, and suppliers will be approached.
• Conditions to closing: financing, landlord consent, franchisor approval, key customer consent, regulatory approvals, or satisfactory diligence.
• Exclusivity: whether the seller must stop speaking with other buyers, for how long, and what happens if the buyer misses agreed milestones.

The confidentiality agreement, often called an NDA, should usually be signed before the seller releases detailed financials, customer identities, pricing, source code, supplier pricing, internal playbooks, or trade secrets. A buyer does need enough information to evaluate the business, but that does not mean every document should be shared on day one.

Trade secret protection under the federal Defend Trade Secrets Act depends heavily on whether the owner takes reasonable measures to keep the information secret. A seller that discloses customer lists, formulas, algorithms, playbooks, or pricing models without a suitable NDA may weaken the argument that the information was treated as confidential.

The NDA should be tailored to the sale process. It should cover the buyer, its advisors, financing sources, and anyone else receiving information. It should restrict use of the information to evaluating and negotiating the transaction, require secure handling, and set rules for return or destruction of information if the deal does not close.

Seller owners should also control disclosure in stages. Early diligence might include summary financials and anonymized customer metrics. More sensitive items, such as named customer contracts, proprietary code, supplier rebate terms, and platform account details, can be released later after the LOI is signed and buyer seriousness is clear.

Get Your Contracts, IP, and Data Ready for Diligence

The most valuable legal cleanup usually happens where contracts, intellectual property, privacy, and assignment rights intersect.

Buyers often care less about whether documents exist and more about whether the documents support the story the seller is telling. If revenue is recurring, the buyer wants enforceable customer contracts. If margins depend on a supplier, the buyer wants that supplier agreement to continue after closing. If the business is brand driven, the buyer wants proof that the seller owns the name, logo, content, and digital assets.

Customer Contracts and Assignment Issues

Customer contracts should be reviewed for assignment, change of control, termination, refund, service level, and most favored customer terms. In an asset sale, many customer contracts cannot simply be handed to the buyer unless the contract permits assignment or the customer consents. In an equity sale, the contract may technically stay with the same entity, but a change of control clause may still require consent.

That issue matters in very practical ways. A buyer may value your business based on 80 active customer accounts. If 30 of those contracts require consent and five major customers can terminate for convenience at any time, the buyer may ask for a lower price, a larger holdback, or a closing condition tied to customer consents.

Under the Uniform Commercial Code, sale of goods contracts may also involve specific rules for assignment, delegation, warranties, and obligations. Service contracts, software subscriptions, agency arrangements, and professional services agreements often turn on general contract law and the exact wording of the agreement. State law can affect interpretation, so a licensed attorney should complete a contract review of the key contracts that drive the valuation.

Supplier, Lease, and License Agreements

Supplier agreements can be just as important as customer contracts. A restaurant, retailer, manufacturer, or ecommerce business may rely on exclusive supply, preferred pricing, distribution territories, or minimum order rights. If those rights cannot be assigned, the buyer may not be buying the same economics that made the business attractive.

Commercial leases require special attention. Landlord consent is commonly needed for an assignment of the lease, a sublease, or a change in control of the tenant entity. Some leases also give the landlord the right to review the buyer's financial condition or require a guaranty. If the location is central to the sale, landlord consent should be treated as a closing issue, not an afterthought.

Software licenses, franchise documents, marketplace terms, payment processor terms, and platform rules may also restrict transfers. A seller should not assume that a login, account, or license can be transferred just because the buyer is purchasing the business.

IP Ownership and Brand Assets

Intellectual property diligence often reveals avoidable gaps. The business may use a logo created by a freelancer with no written assignment. A founder may have registered the domain in a personal account. A contractor may have built software without assigning copyright. A trademark may be used in commerce but not filed with the United States Patent and Trademark Office.

Trademark rights in the US arise from use, and federal registration under the Lanham Act can provide stronger nationwide benefits and public notice. Buyers will usually want to know what trademarks the business uses, whether they are filed or registered with the USPTO, whether there are office actions or disputes, and whether the marks are owned by the selling entity rather than an individual founder.

Copyright under the federal Copyright Act generally protects original works such as website copy, photos, software code, graphics, videos, training materials, and product content. Copyright ownership does not automatically transfer to a company just because the company paid for the work, especially for independent contractor work. Written assignments and work made for hire language should be checked before diligence begins.

For trade secrets, the buyer will want to see confidentiality practices. That can include NDAs, employee confidentiality clauses, access controls, internal policies, and clear treatment of confidential information. If a process is central to the business value, the seller should be able to show how it has been protected.

Privacy, Data, and Digital Compliance

Customer data can be an asset, a liability, or both. A buyer may want email lists, customer profiles, order history, analytics, support tickets, and user accounts. The seller should review whether its privacy policy, customer notices, vendor contracts, and consent records allow the transfer or continued use of that data after closing.

At the federal level, the Federal Trade Commission Act gives the Federal Trade Commission authority to police unfair or deceptive acts or practices, including misleading privacy and data security statements. If a seller promised customers that personal information would only be used in specific ways, a sale process should not ignore that promise.

Some industries have specific privacy, security, or data transfer rules. State privacy laws may also apply depending on the business, data volume, customers, and operations. The seller should identify sensitive data early, including health information, financial information, precise location data, and employee information, and confirm what transfer steps are needed with a licensed attorney where the issue is material.

Negotiate the Sale Agreement and Closing Documents

The purchase agreement turns the deal outline into binding obligations, risk allocation, and the mechanics needed to complete the transfer.

For many small business owners, the purchase agreement, often called a business sale agreement, is the central document in the transaction. It should not simply repeat the LOI. It should set out exactly what is being sold, how and when the price is paid, what approvals are needed, what happens between signing and closing, and who bears responsibility for past and future risks.

In an asset purchase, the main agreement is often called an asset purchase agreement. In an equity sale, it may be called a stock purchase agreement, membership interest purchase agreement, or equity purchase agreement, depending on the entity type. The title matters less than whether the agreement fits the business and the transaction structure.

Key provisions commonly include:

• Assets included: goodwill, inventory, equipment, vehicles, websites, domain names, social media accounts, trademarks, copyrights, customer lists, phone numbers, files, permits, and contract rights.
• Assets excluded: cash, personal vehicles, personal devices, certain accounts receivable, nonbusiness assets, or assets the seller wants to retain.
• Liabilities assumed: specific obligations the buyer agrees to take on, such as post closing performance under assigned contracts.
• Liabilities excluded: seller debt, pre closing taxes, product returns, pending disputes, unpaid vendors, or liabilities not expressly assumed.
• Price mechanics: cash at closing, seller financing, earnouts, escrow, holdbacks, inventory adjustments, working capital targets, and payment default remedies.
• Representations and warranties: seller statements about authority, ownership, contracts, financials, IP, compliance, litigation, taxes, and undisclosed liabilities.
• Covenants: promises about operating the business normally before closing, preserving relationships, obtaining consents, providing access, and cooperating after closing.
• Indemnity: rules for who pays if a representation is false, a liability appears, or a third party claim relates to the pre closing business.
• Closing conditions: required consents, financing, lease assignment, clean title to assets, approval by owners, or delivery of specific documents.

The closing package then carries out the deal. In an asset sale, closing documents may include a bill of sale, assignment and assumption agreement, IP assignment, domain transfer documents, vehicle transfer documents, lease assignment, contract assignments, customer notices, secretary or officer certificates, payoff letters, lien releases, and closing statement.

For IP, the parties may need separate trademark assignments filed with the USPTO and copyright assignments recorded with the US Copyright Office where relevant. The sale agreement should not leave practical control behind. Domain registrars, app stores, ad accounts, social media accounts, payment processors, code repositories, and cloud accounts all need a transfer plan.

Employee issues need careful handling. In an asset sale, employees usually move only if the buyer offers them new employment. In an equity sale, the employing entity may continue, but benefits, policies, and control may change. Employment law is heavily affected by state law, employee agreements, and benefit plans, so sellers should confirm the process before making announcements or promises to staff.

Taxes also affect deal economics and structure. Owners should involve a qualified tax professional early, because purchase price allocation, asset categories, seller financing, and entity type can materially change tax outcomes. The legal documents should match the commercial and tax structure chosen by the parties.

A common mistake is signing a purchase agreement that says assets transfer at closing, while the practical transfers happen days or weeks later. If the buyer needs immediate control of a website, phone number, booking system, source code repository, or payment account, the closing checklist should identify who will log in, who will authorize the transfer, and what backup plan applies if a platform blocks transfer.

FAQs

What Legal Documents Do I Need to Sell a Small Business?

Most small business sales need an NDA, an LOI, a purchase agreement, disclosure materials, assignment documents, closing certificates, and transfer documents for contracts, IP, accounts, equipment, and leases. The exact list depends on whether the deal is an asset sale or an equity sale.

Is a Letter of Intent for a Business Sale Binding?

An LOI is often partly binding and partly nonbinding. Price and deal structure may be nonbinding, while confidentiality, exclusivity, expenses, governing law, and process obligations may be binding. Read the binding provisions carefully before signing.

Can I Transfer Customer Contracts to the Buyer?

Only if the contract and applicable law allow it, or the customer gives any required consent. Asset sales often require assignment consent. Equity sales may still trigger change of control clauses, so key customer contracts should be reviewed early.

What IP Documents Should I Prepare for a Sale?

Prepare trademark records, copyright records, domain account details, software and design assignments, contractor IP assignments, employee invention assignments, license agreements, and any USPTO or Copyright Office records. The buyer will want proof that the selling entity owns or can transfer the IP.

When Should I Start Legal Cleanup for a Business Sale?

Start as soon as you are considering a sale, ideally before approaching buyers. Fixing unsigned contracts, missing IP assignments, lease consent issues, and privacy gaps is much easier before the buyer has identified them in diligence.

Key Takeaways

• A sale process is smoother when your diligence folder proves ownership, authority, contracts, IP rights, data rights, and transfer mechanics.
• The LOI should set commercial expectations without giving away unnecessary exclusivity or creating accidental binding obligations.
• Customer contracts, supplier agreements, leases, software licenses, and platform accounts should be checked for assignment and change of control restrictions.
• IP cleanup should cover trademarks, copyright, domains, software, contractor work, founder contributions, confidentiality, and trade secrets.
• The purchase agreement and closing documents should match the deal structure and include practical steps for transferring assets and control.
