A comprehensive 12-month preparation checklist for business owners planning to sell — covering financials, operations, legal, and value enhancement.
The difference between a business that sells at 6x EBITDA and one that sells at 9x EBITDA is almost never the business itself — it's the preparation. Buyers pay premiums for businesses that are well-documented, financially clean, operationally independent, and positioned for growth. They discount businesses that are owner-dependent, financially opaque, and operationally fragile. Preparation is the lever that moves you from one category to the other.
This is the 12-month checklist for preparing your business for sale. It is organized by time horizon — what to do 12 months out, 6 months out, 3 months out, and 30 days before going to market.
Most business owners underestimate how long it takes to prepare a business for sale. The things that matter most to buyers — management team depth, recurring revenue, clean financials, documented processes — cannot be manufactured in 60 days. They require sustained effort over 12-24 months.
If you're planning to sell in the next 1-3 years, start now. Every month you delay is a month of preparation you won't have.
Get a realistic valuation. Before you can prepare for a sale, you need to understand what your business is worth today and what it could be worth with preparation. Work with an M&A advisor or use industry multiple data to build a realistic valuation range. This gives you a baseline and helps you prioritize your preparation efforts.
Upgrade your financial reporting. If you're on cash-basis accounting, move to accrual. If you don't have monthly management accounts, build them. Buyers expect:
Get your financials reviewed or audited. Reviewed financials (less expensive than audits) signal to buyers that your numbers have been independently verified. For deals over $5M, buyers will often require audited financials. Start the process now so you have 3 years of reviewed/audited statements by the time you go to market.
Clean up your adjusted EBITDA. Document every add-back with receipts, invoices, or other supporting documentation. Buyers will scrutinize every add-back, and undocumented add-backs will be removed from the calculation.
Separate personal and business expenses. If you've been running personal expenses through the business (vehicle, travel, meals), document them clearly and stop running anything that can't be clearly justified as a legitimate business expense.
Build your management team. This is the single most important thing you can do to maximize your sale value. If the business is dependent on you personally, buyers will discount heavily. Start building your #2 now:
Document your processes. Buyers are buying a business, not a job. Documented processes reduce key-person risk and make the business more transferable:
Identify and address operational weaknesses. What are the 3-5 biggest operational risks in your business? Address them now, before buyers find them in due diligence.
Conduct a legal audit. Review all material contracts, IP ownership, employment agreements, and compliance status:
Address any legal issues. Pending litigation, regulatory violations, or IP ownership issues will create significant problems in due diligence. Address them now.
Ensure proper entity structure. Work with your attorney and CPA to ensure your entity structure is optimal for a sale. C-corporations may face double taxation on an asset sale; S-corporations and LLCs typically don't.
Grow recurring revenue. The single biggest driver of multiple premium is recurring revenue. In the 6-12 months before going to market, focus on:
Reduce customer concentration. If one customer represents more than 20% of your revenue, actively work to diversify. This is a slow process — start early.
Improve EBITDA margins. Identify the highest-cost, lowest-value activities and eliminate or reduce them. Buyers pay for EBITDA, and every dollar of margin improvement is worth 5-10x in enterprise value.
Invest in growth. Buyers pay premiums for businesses that are growing. If you've been managing the business for cash flow rather than growth, consider investing in growth initiatives that will show up in your TTM financials by the time you go to market.
Retention planning for key employees. Identify the 3-5 employees who are most critical to the business's performance. Develop retention packages (bonuses, equity, long-term incentive plans) that will keep them through the sale process and post-close.
Succession planning for the owner. If you're planning to exit completely post-close, ensure there is a clear succession plan. Who will run the business after you leave? Is that person ready?
Management team depth. Buyers will interview your management team during due diligence. Make sure your team can articulate the business's strategy, operations, and growth plan without you in the room.
Build a financial model. Develop a 3-year financial projection that shows buyers the growth potential of the business. The model should be conservative but compelling — showing realistic growth based on specific, defensible assumptions.
Analyze working capital. Understand your working capital cycle and calculate your "normalized" working capital. This will be the basis for the working capital peg in your purchase agreement.
Tax planning. Work with your CPA to model the tax implications of different sale structures. The difference between an asset sale and a stock sale, or between a lump-sum payment and an installment sale, can be millions of dollars in taxes.
Write your CIM. The Confidential Information Memorandum is your primary marketing document. It should be professional, factual, and compelling. Key sections:
Build your virtual data room. Organize all due diligence documents in a secure virtual data room. Buyers will request these documents during due diligence, and having them organized in advance signals professionalism and reduces delays.
Prepare your management presentation. You will present the business to potential buyers in 60-90 minute management presentations. Prepare a presentation that tells the story of the business, highlights the investment thesis, and addresses the most common buyer questions.
Build your target buyer list. Identify the 20-50 most qualified potential buyers for your business. Include:
Prioritize buyers. Not all buyers are equal. Prioritize buyers based on:
Hire a transaction attorney. If you haven't already, hire a transaction attorney who specializes in M&A. Interview at least 3 candidates and choose someone with specific experience in your industry and deal size.
Engage your CPA for transaction support. Your regular CPA may not have M&A transaction experience. Ensure you have a CPA who can support the due diligence process and advise on transaction tax planning.
Consider a sell-side Quality of Earnings. A sell-side QoE, conducted by an independent accounting firm, validates your adjusted EBITDA and identifies any issues before buyers find them. For deals over $5M, this is increasingly standard and can significantly accelerate the due diligence process.
Review and finalize your CIM. Have your attorney and CPA review the CIM for accuracy and completeness. Ensure all financial data is current and reconciled.
Populate your virtual data room. Ensure all due diligence documents are uploaded, organized, and accessible. Standard categories include:
Prepare your teaser. Write a one-to-two page anonymous teaser that describes the business without identifying it. The teaser is the first document you share with potential buyers.
Brief your management team. If your management team will be involved in the sale process (management presentations, due diligence interviews), brief them on the process and what to expect. Ensure they understand the confidentiality requirements.
Set your walk-away price. Before you go to market, decide your minimum acceptable price and terms. This prevents you from making emotional decisions during the heat of negotiations.

Every buyer will conduct due diligence. Here's what they're looking for and how to prepare:
Financial due diligence: Buyers hire a QoE firm to verify your adjusted EBITDA. Prepare by having clean, reconciled financials and documentation for every add-back.
Legal due diligence: Buyers' attorneys will review all material contracts, IP ownership, and litigation history. Prepare by conducting your own legal audit and addressing any issues.
Operational due diligence: Buyers will evaluate your operations, technology, and management team. Prepare by documenting your processes and ensuring your management team can articulate the business's operations.
Commercial due diligence: Buyers may hire consultants to validate your market position. Prepare by having clear, data-supported answers to questions about your competitive position, market size, and growth opportunities.
Management interviews: Every member of your senior team will be interviewed. Prepare by briefing your team on the process and ensuring they can speak confidently about the business.
