Private equity firms, strategic acquirers, and family offices expect institutional-quality documentation before they'll take an offer seriously. A verbal explanation of "great margins" doesn't cut it. Buyers want paper trails.
This guide breaks down the financial, legal, and transaction documents needed to sell a business, organized by stage, so you know what to gather and when.
Key Takeaways
- Assemble financial, corporate, operational, and transaction documents before going to market
- Buyers review multi-year financials, tax returns, and organizational records before making offers
- Missing or disorganized files are a leading cause of stalled or collapsed deals
- An M&A advisor packages materials to support stronger valuation and cleaner diligence
Financial Documents Buyers Will Request
Financial statements, meaning your income statement, balance sheet, and cash flow statement, are the baseline every buyer requests. Buyers want a multi-year history built on consistent accounting standards. Sloppy or inconsistent books signal risk before a single number gets discussed.
Tax returns matter just as much. Business and payroll/employment tax filings validate what your financial statements claim. Buyers cross-reference them to confirm reported income matches what you told the IRS.
Normalizing Your Numbers with EBITDA Add-Backs
Buyers rarely value reported EBITDA. They value Adjusted EBITDA, and there are four adjustment categories they expect to see documented: owner compensation above market levels, personal expenses recorded through the company, one-time legal or consulting fees, and non-recurring operational disruptions.
A worked example of how that arithmetic reads on paper:
| Line | Amount |
|---|---|
| Reported EBITDA | $3,200,000 |
| Owner compensation adjustment | +$200,000 |
| One-time legal fees | +$75,000 |
| Non-recurring equipment repair | +$125,000 |
| Adjusted EBITDA | $3,600,000 |
Every one of those four lines needs a document behind it. Normalization only works when each adjustment is documented and defensible. Vague or aggressive add-backs invite pushback and can shrink the final price.
Buyers will also request:
- Accounts receivable and payable schedules: assess near-term liquidity
- Debt schedules: show leverage and repayment obligations
- Projections and KPIs: often anchor earn-out structures in the final deal
Poor due diligence is a recurring theme in failed transactions. Bain’s global M&A research found that nearly 60% of executives attributed deal failure to poor due diligence. A separate Bain survey of senior M&A managers found half said diligence overlooked major problems entirely. The more specific risk is the add-back file itself. In Axial's 2025 Dead Deal Report, quality of earnings discrepancies over EBITDA went from 10.6% of broken letters of intent in 2023 to 21.3% in 2025, roughly doubling in two years, while non-QoE diligence findings rose from 19.1% to 25.3%. Organized, consistent financials reduce that risk and keep valuation talks focused on earnings power, not cleanup.
Corporate and Legal Governance Documents
Buyers need to know who actually has the legal authority to sell. That starts with your articles of incorporation, bylaws, and shareholder or operating agreements. Without these, a buyer can't confirm the deal is even legally possible to close.
Ownership records need the same early attention. Stock certificates, transfer history, and cap table documentation should be cleaned up well before diligence, especially in multi-generational or family-owned businesses, where shares often moved between relatives informally for decades.
Other governance essentials include:
- Material contracts, leases, and licenses: confirm assignability before buyer talks; a non-transferable lease can stall closing
- Disclosure schedules: list litigation, debts, and material agreements to limit post-closing liability
- Employment, IP assignment, and non-compete agreements: buyers use these to gauge retention risk and protect deal value
Gaps in any of these documents don't just slow the deal. They give a buyer openings to renegotiate price mid-process.
Transaction Documents That Drive the Deal
These documents move the deal from first contact to a signed contract, and each one builds on the last.
- Teaser: one or two pages, distributed before any confidentiality agreement is signed, so it withholds the company's identity and describes the opportunity in ranges: industry, general location, revenue range, EBITDA range, core products, key growth opportunities.
- Non-Disclosure Agreement (NDA): signed by buyers the teaser interested; protects financials, customer lists, and trade secrets before you share anything meaningful.
- Confidential Information Memorandum (CIM): the full narrative. A complete CIM covers company history, industry overview, products and services, customer relationships, management team, financial performance, growth strategy, acquisition opportunities, and risks with mitigants.
- Letter of Intent (LOI): non-binding outline of price, exclusivity, and deal structure that becomes the roadmap for everything that follows. In the lower middle market an Indication of Interest often arrives first, carrying less detail.
- Purchase Agreement: binding contract (asset or stock) that locks in price, representations, warranties, and indemnification.
At Exit Boston, our transaction marketing team, led by Thor, builds buyer-specific CIMs and Investment Summaries tailored to each acquirer's criteria. A private equity firm, a strategic acquirer, and a family office rarely care about the same things, so one generic CIM seldom lands with all three.
Matching the pitch to what each buyer type values creates competitive tension. That tension is often what produces premium offers instead of a single take-it-or-leave-it bid.
Closing and Post-Sale Documents
Once terms are locked, the paperwork shifts to finalizing the transfer.
- Bill of Sale: legally finalizes the asset or share transfer
- Assignment of Contracts and Leases: moves key agreements over to the buyer
- Board Resolutions: authorize the transaction on behalf of the company
- Promissory Note: if seller financing is part of the deal, spells out repayment terms, interest, and default provisions
- Transition or Consulting Agreements: keep you involved post-close for continuity; buyers often request these to protect customer and supplier relationships during the handoff
None of these should be drafted at the last minute. Waiting until the week of closing to settle assignment language or transition terms is how deals miss their target date.
Organizing Your Documents for a Smooth Sale
Start a document review with your accountant and an M&A advisor well before you go to market. Early review catches gaps and inconsistencies while you still have time to fix them, not after a buyer has already flagged a problem.
Build a virtual data room organized by category. The six categories buyers request in confirmatory diligence are consistent enough to build against directly:
- Financial statements
- Tax returns
- Customer contracts
- Supplier agreements
- Employee information
- Operational reports
Add two working folders alongside them: entity and ownership records, and transaction-specific consents, disclosures, and deal papers.
Having this ready before due diligence begins signals to buyers that you run a tight operation, which builds confidence before they've reviewed a single line item.
That same early pass is where Exit Boston's advisory work on valuation, buyer readiness, and deal structuring often surfaces problems, missing consents, outdated agreements, unclear ownership records, before they reach a buyer's desk. Finding these issues early is far cheaper than finding them mid-negotiation.
Frequently Asked Questions
What documents do I need to sell my business?
Sellers typically need financial statements, tax returns, corporate governance records, key contracts, an NDA, an LOI, and a purchase agreement. Exact needs vary by asset vs. stock deal and by industry.
What is a sale of business agreement?
A sale of business agreement is the binding contract, usually an Asset Purchase Agreement or Stock Purchase Agreement, that sets price, terms, representations, and closing conditions.
How far in advance should I start preparing documents to sell my business?
Most advisors recommend 6-12 months of preparation to clean up financials and organizational records. This gives you time to fix gaps before buyers find them.
Do I need a lawyer to sell my business?
Most sales should involve a qualified M&A attorney. Legal and tax complexity, reps and warranties, and closing conditions make DIY deals risky for both sides.
What's the difference between an LOI and a purchase agreement?
The LOI is non-binding and sets initial terms like price and exclusivity. The purchase agreement is the final, binding contract that governs the actual sale.
What is a Confidential Information Memorandum (CIM) used for?
A CIM markets your business to qualified buyers, presenting financial and operational details in a structured format during the active marketing phase of a sale.
