The number one regret sellers report after a business sale is not a bad deal. It is not having started sooner. According to BNY Wealth's 2025 Insights for Private Business Owners report, 38% of sellers wished they had given themselves more time to accomplish all the tasks necessary for the sale, and 40% wished they had started planning further in advance. Not legal planning, not tax structuring. The preparation work itself. The financial cleanup, the documentation, the normalization of earnings that takes months to complete correctly.
A two to three year horizon sounds like ample time. It is not as much as it feels. The median small business sale takes 170 days to close once the business is listed, and 3 to 4 months of that window is consumed by post-LOI due diligence. That means the preparation work needs to be substantially complete before you ever have a conversation with a broker. Which means the clock starts now, not when you feel ready.
This article covers the financial preparation work a CFO leads in the two to three year window before a transaction: the EBITDA normalization, the financial statement cleanup, the working capital management, and the documentation that determines whether a buyer's QoE team finds problems you could have fixed or problems you cannot.
Why the Financial Preparation Timeline Is Not Optional
Most owners who plan a sale in two years spend the first twelve months running the business and thinking about the sale, and the second twelve months scrambling to prepare for it. That pattern consistently produces worse outcomes than owners who front-load the preparation work.
The reason is compounding. Financial preparation is not a document-gathering exercise. It is a financial improvement exercise that requires time for the improvements to show up in the financial statements.
If your EBITDA needs to be normalized, the normalization has to be documented, consistent, and reflected in at least two years of financial statements before a buyer will give it full credit. An add-back that appears in one year's statements looks like an adjustment. An add-back documented consistently across three years of statements with supporting records is simply part of the clean picture.
If your close process is slow and your management reporting is thin, improving it takes time and produces results that compound. A business that delivers a management reporting package within five business days of month-end, every month for eighteen consecutive months, goes into a transaction demonstrating financial discipline.
If customer concentration is a risk, reducing it takes twelve to eighteen months minimum. You cannot fix a 40% single-customer revenue concentration in a quarter. You can build it down materially over two years, which is the difference between a buyer discounting the multiple or paying full price.
The financial preparation starts the day you set the date. Not the day you feel ready to think about it.
Months One to Six: Assessment and Foundation
The first six months of a two to three year exit preparation window are about understanding exactly where you stand and fixing the most foundational issues before they become discovered problems.
Get a clear picture of your current normalized EBITDA. Before any improvement work begins, you need to know what the business actually earns on a normalized basis. Not net profit. Not the number on the tax return. Normalized EBITDA with owner compensation adjusted to market rate, personal expenses removed, one-time items properly classified, and depreciation added back. This is the number a buyer will build their model from, and knowing it accurately is the starting point for everything else.
Most owners are surprised by this number. The mental model of what the business earns almost always differs from the actual normalized EBITDA. Getting that number right in month one sets the baseline for all the improvement work that follows.
Assess your add-back documentation. Every item in your EBITDA normalization needs documentation that will survive buyer scrutiny. Go through every add-back in your current normalization and ask: if a buyer's QoE team asked for the supporting records for this item, what would you produce? An add-back without clean, complete documentation will be challenged or stripped. The time to build that documentation is now, not during due diligence.
Evaluate your financial statement consistency. Pull three years of financial statements and reconcile them to the corresponding tax returns. If there are unexplained differences, identify them now and build the reconciliation notes. Buyers and their QoE teams will do this comparison. A clean reconciliation that already exists with clear explanations signals financial discipline.
Improve the close process if it is slow. If your books take three weeks to close each month, that is the first operational improvement to make. A business going into a transaction needs to produce financial results within five to seven business days of month-end. That standard is achievable for most businesses in the $3M to $30M range and it requires building the process and discipline over months, not weeks.
Months Seven to Eighteen: EBITDA Improvement and Documentation Build
The middle phase of exit preparation is where the substantive financial value is created or protected. The assessment is complete. The foundation is in place. This is the period where the work that moves both the earnings number and the multiple gets done.
Build the EBITDA improvement plan and execute it. The two levers that determine sale price are normalized EBITDA and the multiple it commands. The article on how to increase business value before selling covers the specific levers in detail. In this phase, the CFO is modeling the financial impact of each improvement initiative, tracking progress against the baseline, and building a narrative that shows buyers a business trending in the right direction.
The improvements that produce the highest return in this window are the ones that affect normalized EBITDA most directly: gross margin improvement through pricing or procurement, overhead reduction through rationalization rather than cost-cutting that damages operations, and working capital efficiency that demonstrates cash discipline without starving the business of what it needs to grow.
Build three years of consistent management reporting. Buyers and their advisors look at the trailing financial record as evidence of how the business is managed. A management reporting package that has been consistent for 18 months before a transaction shows buyers what the business looks like when it is being run well.
Address customer concentration if it is an issue. A single customer above 20 to 25% of revenue is a concentration risk that buyers discount in the multiple. If your business has this structure, the 18-month window starting now is the right time to work on reducing it. Not by losing the customer, but by growing the revenue base around them.
Document your add-backs with current, consistent records. Every add-back in the normalization needs a supporting schedule that can be opened in a data room and understood without a conversation. Owner compensation: W-2 or K-1 plus the market rate benchmark for the replacement role. Personal vehicle: expense report with documentation that the vehicle is personal and not required for business operations. Non-recurring legal settlement: legal invoices, the date the matter closed, and a representation that it will not recur.
BNY Wealth 2025 Insights for Private Business Owners: 38% of sellers wished they had given themselves more time to accomplish all the tasks necessary for the sale. The sellers who close on their terms are the ones who started the financial preparation work in the months or years before the process began, not in the weeks before.
Months Eighteen to Thirty: Transaction Readiness
The final phase is about getting the business to a state where a buyer's due diligence team finds nothing they did not already expect. This is not the time for major improvements. It is the time for documentation completeness, working capital optimization, and preparation for the QoE process.
Prepare for the quality of earnings review. The QoE process tests every number in your financial statements from the buyer's perspective. A sell-side QoE conducted before going to market identifies the issues a buyer's team would find and gives you the opportunity to address them on your timeline rather than theirs. The article on quality of earnings: what it is and why it matters covers the full process in detail.
At a minimum, the CFO prepares the financial package as if a QoE team will review it: the normalized EBITDA with full add-back documentation, the trailing twelve months reconciled to prior annual periods, the customer revenue schedule with trend analysis, the working capital history, and the AR aging.
Manage working capital deliberately. Most transactions include a working capital peg, an agreed level of net working capital to be delivered at closing. The peg is set based on historical averages, so working capital management in the twelve months before closing directly affects the peg negotiation. The businesses that optimize working capital in this window, tighten receivables collection, right-size inventory, and negotiate appropriate payables terms, deliver a cleaner working capital picture that supports a favorable peg and reduces the risk of a post-closing adjustment.
Build the trailing twelve months package. Buyers focus most on the most recent twelve months of performance. If the TTM is the strongest period in the company's history, it needs to be clearly presented with context showing the trend is sustainable. If the TTM is softer than prior years, it needs a clear explanation and evidence that the softness is temporary. In either case, the CFO prepares the TTM narrative before a buyer's team interprets it without your input.
Stabilize the management team. Owner dependency is one of the most common reasons buyers discount a multiple. Every month of this preparation window is an opportunity to document functions, cross-train capable people, and demonstrate that the business runs whether or not the owner is in the building. This is not just operational preparation. It is financial preparation, because the multiple a buyer pays is directly tied to their confidence in continuity.
What This Work Produces
A business that enters a transaction process having done this work looks different from one that has not. The financial statements are consistent and clean. The add-backs are documented. The management reporting has been running on a professional standard for two years. The working capital is well-managed. The QoE team opens the data room and finds a business that is organized rather than a business that is scrambling.
That difference translates into the purchase price and the deal structure. Buyers pay higher multiples for businesses that demonstrate financial quality. They negotiate fewer price adjustments. They complete due diligence faster. They are less likely to retrade.
The businesses that close on their terms are the ones that started this work before the process began. A quick exit that sacrifices 20 to 30 percent of potential value versus a prepared process is not a better deal. It is the cost of not having had enough time.
