What Documents Are Needed to Sell a Business? 2026 Checklist

The documents needed to sell a business fall into two groups: records that prove what the company earns and owns, and agreements that transfer it to a buyer. Most US sellers need three years of financials and tax returns, corporate and contract records, an NDA, a letter of intent, a purchase agreement, and closing documents. Here is what you need at each stage.

The Core Documents at a Glance

Buyers, lenders, and attorneys ask for the same core set in nearly every deal. Have these ready before you go to market:

• Three years of profit and loss statements, balance sheets, and business tax returns
• A seller’s discretionary earnings (SDE) or EBITDA recast with documented add-backs
• Accounts receivable and accounts payable aging reports
• Formation documents, ownership records, and a certificate of good standing
• Your commercial lease and key customer, supplier, and vendor contracts
• An employee census, payroll records, and benefit plan documents
• A fixed asset and inventory list
• Licenses, permits, and proof of intellectual property ownership
• Transaction documents: NDA, letter of intent, purchase agreement, and closing deliverables

Documents Needed to Sell a Business: Checklist by Stage

You do not need every document at once. Sharing too much too early exposes sensitive data, while gaps late in the process can stall a deal. This table maps each stage to what is typically produced and who usually prepares it.

Stage 1: Preparation and Valuation Documents

This is the heaviest lift, and it starts months before a listing. The records you collect here feed your business valuation, your marketing materials, and later the due diligence data room.

Financial Records

Buyers value a business on its earnings, so financial records carry the most weight. Your CPA should help you assemble:

• Profit and loss statements for the last three full years plus year to date
• Balance sheets for the same periods
• Federal and state business tax returns for three years, which buyers and lenders compare against your internal statements
• SDE or EBITDA recast showing add-backs such as owner salary, personal expenses run through the business, and one-time costs, each backed by receipts or ledger detail
• AR and AP aging reports showing who owes you, whom you owe, and how long balances have been open
• Bank statements, debt schedules, and loan agreements
• Sales by customer, product, or channel to show concentration and trends

Add-backs are where valuations are won or lost, and buyers usually discount any add-back you cannot document. Before you engage a broker, you can test a rough range with the business valuation calculator.

Legal and Corporate Records

These prove that you own what you are selling and have the authority to sell it. Gather articles of incorporation or organization, bylaws or the operating agreement, shareholder or member records, meeting minutes and resolutions, any buy-sell agreements, and a current certificate of good standing from your state. Note any pending litigation, liens, and settlements.

Contracts and Leases

Collect every agreement a buyer would inherit or rely on: the commercial lease and amendments, customer contracts, supplier and vendor agreements, distribution or franchise agreements, equipment leases, and loan documents. Flag any contract that requires consent to assign or has a change-of-control clause, because the other party may need to sign off before closing.

Employees and HR

Prepare an employee census listing roles, hire dates, pay, and status, with names withheld until later in the process. Add the employee handbook, offer letters, employment and contractor agreements, staff confidentiality or non-compete agreements, payroll tax filings, benefit plan documents, and workers’ compensation policies.

Operations

Buyers want to know the business can run without you. Document standard operating procedures, an organization chart, key vendor and supplier lists, inventory counts and valuation method, a fixed asset list with condition and ownership, insurance policies, and any customer concentration.

Intellectual Property

List trademarks, copyrights, patents, and trade secrets, with registration numbers where they exist. Include agreements showing that employees and contractors who created logos, software, or content assigned those rights to the company. Missing assignments are a common diligence finding.

Licenses and Permits

Compile federal, state, and local business licenses, professional licenses, health and safety permits, sales tax registrations, and industry-specific permits. Some licenses transfer with the business and others must be reissued to the buyer, so note which is which early.

Digital Assets for Online Businesses

For ecommerce, SaaS, and content businesses, digital assets are often most of the value. List domains and the registrar accounts that hold them, hosting and software accounts, code repositories, marketplace and payment processor accounts, analytics and traffic reports, email lists with consent records, social media accounts, and subscription or churn metrics. Confirm that each account is in the company’s name and can be transferred under the platform’s terms.

Stage 2: Marketing Documents (NDA and CIM)

Once the business is priced, your broker markets it confidentially. A blind teaser describes the opportunity without naming the company. Interested buyers then sign a non-disclosure agreement (NDA) before they see anything sensitive, and many brokers also ask for proof of funds at this point. Owners of online stores can follow each phase in our guide on how to sell an ecommerce business.

Qualified buyers receive the confidential information memorandum (CIM), a detailed document covering the business model, history, customers, team, growth opportunities, and recast financials. Your broker or M&A advisor usually writes the CIM from your Stage 1 records, so the quality of those records shows up directly here.

Stage 3: The Letter of Intent

A letter of intent (LOI) sets out the proposed price, deal structure, the split between cash, seller financing, and any earnout, working capital terms, the due diligence period, and an exclusivity period. Most LOI terms are non-binding, but confidentiality and exclusivity provisions often are binding. Review the exclusivity clause carefully, since it takes you off the market while the buyer completes diligence. Ask your attorney how long it runs and what ends it early.

Stage 4: Due Diligence Documents

After the LOI is signed, the buyer, its lender, and its advisors verify everything. Your broker usually sets up a secure virtual data room organized by the categories above. Expect follow-up requests for items such as monthly financials and bank statements that tie to reported revenue. Online stores get additional platform-specific requests, which we cover in our due diligence checklist for ecommerce sellers.

A few habits keep diligence on schedule:

1. Load the data room before the LOI is signed so the buyer can start immediately.
2. Use consistent file names and a numbered index that mirrors the buyer’s request list.
3. Reconcile your tax returns to your internal statements and explain any differences in writing.
4. Disclose known problems early. Issues found late tend to cost more in price or terms.
5. Track every request and response so nothing is missed or answered twice.

Stage 5: Closing Documents

Attorneys for both sides draft the closing documents, with input from your CPA on tax treatment. The exact set depends on deal structure and state law, but these are the most common.

Asset Sale vs. Stock Sale

In an asset sale, the buyer purchases selected assets and usually takes on only the liabilities it agrees to assume. This structure is common for small businesses and requires a bill of sale and individual assignments. In a stock sale (or membership interest sale for an LLC), the buyer acquires the ownership interest, and the entity keeps its contracts, licenses, and liabilities. Stock sales use a stock purchase agreement and stock powers or interest assignments rather than a bill of sale. The structure changes your tax result, so settle it with your CPA before you sign the LOI.

IRS Form 8594

Form 8594, the Asset Acquisition Statement Under Section 1060, applies when a group of assets that makes up a business is sold and goodwill or going concern value attaches or could attach. According to the IRS instructions, both the buyer and the seller generally must file it with their income tax returns for the year of the sale. The form allocates the price across seven asset classes, from cash in Class I to goodwill in Class VII, and a covenant not to compete falls in Class VI. Agree on the allocation in the purchase agreement so both filings match. For context on the largest class, see how to calculate goodwill value.

Bulk Sale Notices and Tax Clearance

Most states have repealed the old UCC Article 6 bulk sales law, but several still have tax rules that can make a buyer liable for a seller’s unpaid state taxes unless clearance procedures are followed. Buyers therefore often ask sellers for tax clearance before closing. A few examples:

• New York: the buyer files Form AU-196.10, Notification of Sale, Transfer, or Assignment in Bulk, at least 10 days before paying for or taking possession of the business assets, whichever comes first.
• California: a buyer who does not withhold enough of the price to cover the seller’s sales and use tax, or obtain a tax clearance certificate from the California Department of Tax and Fee Administration, can be held liable as a successor.
• Pennsylvania: purchasers must secure a bulk sale clearance certificate from the seller when more than 51 percent of a class of assets is transferred; sellers apply with Form REV-181.

Rules and deadlines vary by state and change over time. Ask your attorney which notices apply where you operate, and budget time, since some agencies take weeks to respond.

Common Documentation Gaps That Cost Sellers

Many deals that slip or reprice do so over paperwork. Watch for these gaps:

• Tax returns that don’t match internal books: buyers and lenders typically rely on what was reported to the IRS.
• Undocumented add-backs: personal expenses without receipts are often removed from SDE.
• Leases near expiration: a short remaining term can reduce value or complicate financing.
• Verbal agreements with key customers: buyers discount revenue they cannot verify.
• IP owned by a founder or contractor: assign it to the company before you go to market.
• Accounts in the owner’s personal name: domains, marketplace stores, and software licenses should be held by the business.

Clean records also affect what you take home after fees and holdbacks. Our guide to success fees in business sales shows how fees and deal terms shape your proceeds.

Who Prepares What: Your Deal Team

You supply the raw records, but you should not draft the transaction documents alone. Your CPA prepares and reconciles financials, advises on structure, and helps with the price allocation. Your attorney drafts or reviews the NDA, LOI, purchase agreement, and closing documents. A business broker values the company, writes the CIM, screens buyers, runs the data room, and keeps the timeline on track. If you are still building that team, start with our guide on how to find a business broker.

This checklist is general information, not legal or tax advice; confirm the specifics for your deal and state with your attorney and CPA.

Next Steps

Start with the financial records, because they drive valuation and every later stage. Then work through the legal, contract, HR, operations, IP, license, and digital asset categories, and fix gaps before a buyer finds them.
