Exit Planning Timeline: Why to Start Preparing 3 Years Before You Sell

Quick answer

Start preparing to sell your business about three years before you want to close. Buyers and SBA lenders judge your company on its last two to three years of verified earnings, so improvements need time to show up as a trend instead of a one-year spike. Three years also gives you room to reduce owner dependence, clean up your books and plan your taxes before a buyer ever opens your files.

Key takeaways

• The best time to start preparing a business for sale is roughly three years before your target closing date, because buyers and lenders evaluate a multi-year earnings history.
• Under current SBA 7(a) rules, a buyer’s loan must be supported by your historical earnings, not by projections, so a last-minute profit jump carries little weight.
• A steady three-year rise in EBITDA earns more trust, and usually a better multiple, than one strong year after two flat ones.
• The slow fixes, such as building a management layer, spreading out customer concentration and changing your tax structure, take years to complete and to be believed.
• The Exit Planning Institute estimates that about half of US business exits are triggered by unplanned events like death, disability, divorce, distress or disagreement.
• In our illustrative example, a three-year runway lifts a sale price from $2,800,000 to $4,725,000, a difference of $1,925,000.

How long does it take to prepare a business for sale?

Plan on about three years to prepare a business for sale properly, plus the months it takes to market and close the deal. That number matches how the people paying you actually evaluate a business.

The Exit Planning Institute’s 2023 National State of Owner Readiness Report puts it plainly: an effective exit strategy typically needs a minimum of three years to have a strategic impact, and three to five years to execute well. McKinsey’s research on small business succession flags the same problem: many owners underestimate how long it takes to prepare for a sale.

Then there is the sale itself. In BizBuySell’s Q2 2026 Insight Report, service businesses that sold spent a median of 155 days on the market, roughly five months, before diligence and closing even finish.

So when you ask “when should I start preparing to sell my business,” the honest answer is: earlier than feels necessary. The reason comes down to how buyers read your numbers.

Buyers and lenders price your last three years, not your last three months

Your sale price is built on a trailing earnings history, and most buyers need a lender to agree with it. In the IBBA’s Q1 2026 Market Pulse survey, 78% of buyers expected to use SBA financing, which means SBA underwriting rules shape what your business can sell for.

Those rules got stricter. Under the SBA’s SOP 50 10 8.1, effective October 1, 2026, a loan for a buyer acquiring your business (what the SBA calls an initial acquisition) must show debt service coverage of at least 1.25x using historical results, either the latest year or an average of the latest two. Lenders can no longer count projected post-sale earnings toward that test. You can see how this caps price in our guide to how SBA financing limits your sale price.

In practice, lenders ask for three full years of the business’s financial statements or tax returns, plus a current interim statement and the same interim period from the prior year. The SBA now directs lenders to use the strongest level of reporting available, in this order: audited, reviewed, compiled, then tax returns.

For deals with a purchase price of $3 million or more, the lender must also order a quality of earnings report. A quality of earnings (QoE) report is an independent accounting review that tests whether your reported profit is real and repeatable. Under the new rules it includes a cash proof that reconciles your books to bank statements and tax filings for the trailing 12 months and the last two fiscal years.

That is why trend matters so much. A business with EBITDA rising steadily over three years tells a buyer the improvement is durable. One great year after two flat ones looks like a spike, and buyers tend to average it down or discount it. EBITDA (earnings before interest, taxes, depreciation and amortization) is the profit figure most buyers multiply to reach a price.

The math is simple: value equals EBITDA times a multiple, as we break down in the three numbers that determine business value. Both of those numbers move slowly. Waiting until the year you want to sell leaves almost no time to move either one.

Why waiting costs you: many exits are not on the owner’s schedule

The biggest cost of waiting is that you may not get to choose when you leave. The Exit Planning Institute estimates that about 50% of US business exits are driven by unplanned events, which it calls the “5 Ds”: death, disability, divorce, distress and disagreement.

McKinsey’s analysis of US small business exits points the same way. Of roughly 510,000 small and midsize business exits in 2022, about 92% were closures, 5% were sales and 3% were transfers. McKinsey estimates that about 6% of all business closures happen because of owner illness or death.

Age raises the stakes. More than half of US small business owners are over 55, and about one in four is 65 or older. The Exit Planning Institute also reports that the business typically equals 80% or more of the owner’s total net worth, so a forced sale is often a forced retirement plan.

When an exit is forced, you sell on the buyer’s terms, at whatever point your numbers happen to be. A three-year runway is how you avoid selling at a weak moment, whether the trigger is planned or not. Here is what that runway looks like, year by year.

36 months out: get an honest baseline and start the slow fixes

Three years out is when you diagnose: what your business is worth today, what is holding the multiple down, and which fixes need the longest lead time.

Get a baseline valuation. You cannot measure progress without a starting number. A formal valuation shows your normalized EBITDA, the multiple your risk profile supports and the specific factors dragging it down.

Start reducing owner dependence. If customers, key vendors or your best employees deal only with you, buyers see risk walking out the door at closing. Hiring or promoting a general manager or operations lead takes time, and that person needs a track record a buyer can see. Our article on the owner trap covers what buyers look for.

Clean up the books. Separate personal expenses from business expenses and move to accrual accounting if you are still on cash basis. If your revenue supports it, consider upgrading from tax-return-only reporting to CPA-reviewed financial statements, since lenders now favor the strongest reporting available.

Stop running income off the books. In our experience, owners underestimate this cost. Keeping $100,000 of profit off the books might save around $30,000 in tax, but at a 4x multiple it costs you $400,000 at sale.

Talk to your CPA about structure. Entity type and deal structure drive how much of the price you keep. Buyers often prefer an asset sale, which gives them a stepped-up tax basis and fewer inherited liabilities. Sellers often prefer a stock sale, which can mean more favorable capital gains treatment. Some changes need years to work. For example, if a C corporation elects S status, the federal built-in gains tax can apply to appreciated assets sold within a five-year recognition period. Your CPA and attorney should guide these decisions for your situation.

Start the personal conversation. Decide what you want life after the sale to look like, what income you need from the proceeds and whether you want to stay on in any role.

24 months out: build the team and clean up the revenue

Two years out is when you execute the hardest operational changes, so they have a full year or more of results before a buyer looks.

Let the management layer run. Your new leaders should be making daily decisions now, with you stepping back from routine sales and operations. In our experience, buyers want to see at least one full year where the business performed without you in the middle of everything.

Fix customer concentration. If one customer is more than 10% of revenue, buyers notice. Concentration of 20% to 30% commonly cuts the multiple by 15% to 25%, and above 30% the discount is commonly 20% to 40%. Diluting a big customer means growing everyone else, which takes time. Read more on how customer concentration affects value.

Shift toward recurring revenue. Service agreements, maintenance plans and subscriptions make revenue more predictable. Recurring revenue commonly earns roughly one to two more turns of EBITDA than comparable one-time revenue.

Put agreements in writing. Convert handshake deals with key customers and suppliers into written contracts that can be assigned to a new owner. Review leases so they extend past your sale date or include renewal options.

Raise EBITDA the durable way. Price increases, better job costing and trimming unproductive spending show up as a steady climb. Cuts that starve the business, like skipping maintenance or delaying hires, tend to get caught in diligence.

12 months out: lock the numbers and pressure-test the deal

One year out, the numbers buyers will see are mostly written. Your job now is to document them and remove surprises.

Build your add-back schedule. Add-backs are owner perks and one-time costs that a buyer would not incur, added back to reach normalized earnings. Each one needs invoices, payroll records or other proof. Under QoE scrutiny, unsupported add-backs simply disappear. See our guide to add-backs and normalization.

Reconcile cash to revenue. Tie monthly bank deposits to reported revenue for the last three years. If your books and tax returns tell different stories, fix the explanation now.

Document one-time events. A big one-off contract or an insurance payout should be labeled clearly so it is not mistaken for a trend, or for a decline when it does not repeat.

Run a mock diligence. Gather contracts, licenses, permits, employee files and leases into a data room, then fix the gaps.

Get an updated valuation. Compare it with your baseline. The gap tells you what your preparation has earned and whether your price expectations are realistic.

The final 6 months: go to market from strength

The last six months are about choosing your moment and your team. Changes this late look like window dressing.

Pick an advisor, a broker or an M&A advisor depending on deal size, and agree on positioning. Prepare your confidential information memorandum around the three-year story your numbers now tell. Keep running the business hard. A dip in performance during the sale process is one of the fastest ways to lose a buyer or reopen the price.

Now let’s put real numbers on what the runway is worth.

Worked example: selling now vs. after a three-year runway

Take an illustrative commercial HVAC service company with about $6 million in revenue. Its EBITDA over the last three years was $760,000, $780,000 and $800,000. The owner handles most key accounts, one customer is 25% of revenue and the books mix personal and business expenses.

Owner A sells now. A buyer prices off the latest year of $800,000 and applies a 3.5x multiple, reflecting the owner dependence and concentration. The price is $800,000 x 3.5 = $2,800,000.

Owner B rushes for 12 months. This owner slashes costs and pushes sales hard for one year, and EBITDA jumps to $970,000. The three-year history is now $780,000, $800,000 and $970,000. Nothing structural changed, so a skeptical buyer averages the three years: $2,550,000 / 3 = $850,000. At the same 3.5x, the price is $850,000 x 3.5 = $2,975,000. The owner hoped for $970,000 x 3.5 = $3,395,000, so $420,000 of expected value never shows up.

Owner C takes a three-year runway. This owner hires a general manager, signs service agreements and grows other accounts until no customer exceeds 10% of revenue. EBITDA rises to $870,000, then $960,000, then $1,050,000. In our experience, a buyer who sees three years of steady, documented growth is far more willing to price off the latest year. With lower risk, the multiple improves to 4.5x, and the price is $1,050,000 x 4.5 = $4,725,000.

Owner C sells for $4,725,000 – $2,800,000 = $1,925,000 more than Owner A. Part of that comes from higher earnings: the extra $250,000 of EBITDA at the old 3.5x adds $875,000. The rest comes from the better multiple: one more turn on $1,050,000 adds $1,050,000. Together, $875,000 + $1,050,000 = $1,925,000.

Owner C also collects three more years of growing profit along the way. And at a $4,725,000 price, an SBA-financed buyer’s lender would need a quality of earnings report, which Owner C’s clean books are ready for.

What if you have less than three years?

Start anyway, and prioritize the fixes that show up fastest. With 12 to 24 months, focus on documentation, add-back support, cash reconciliation and written contracts. Those protect the earnings you already have from being discounted.

The slow fixes, owner dependence and concentration, will not be fully solved, but visible progress still helps. A buyer who sees a capable manager in place for a year, or a top customer shrinking as a share of revenue, can at least see where the trend is heading. You may also need deal terms like a longer transition period or a seller note to bridge the gap, which shifts some risk back to you.

What to do next

Pick your target closing year and count back 36 months. If that date has already passed, your runway starts today.

The first step is the same either way: find out what your business is worth now and what is holding the number down. A certified business valuation gives you that baseline, along with a clear list of what to fix first. Then work the timeline one year at a time.

Frequently asked questions

How long does it take to prepare a business for sale?

Most owners need about three years to prepare a business for sale properly, plus several months to market and close the deal. Buyers and SBA lenders evaluate two to three years of historical earnings, so improvements need time to appear as a steady trend. The Exit Planning Institute says an effective exit strategy typically needs at least three years to have a strategic impact. Owners who start later can still improve documentation and records, but the structural fixes take longer.

When should I start preparing to sell my business?

Start about three years before your target closing date, and earlier if you want to change your tax structure or reduce heavy owner dependence. That window lets you build a management team, reduce customer concentration, clean up your books and show a rising earnings trend. If you plan to sell in under three years, start now with the fastest fixes: documented add-backs, reconciled bank deposits, written contracts and a baseline valuation to show you where the gaps are.

What does an exit planning timeline look like?

A practical exit planning timeline runs about 36 months. Around 36 months out, get a baseline valuation, start reducing owner dependence, clean up your books and talk to your CPA about structure. At 24 months, let your management team run the business and fix customer concentration. At 12 months, document add-backs, reconcile cash to revenue and run a mock diligence. In the final six months, choose your advisor and go to market while performance is strong.

Why do buyers care about three years of financials?

Buyers and lenders use a multi-year history to judge whether your earnings are real and repeatable. Under current SBA 7(a) rules, a buyer’s loan must be supported by historical results, using the latest year or an average of the latest two, not projections. Lenders typically request three years of financial statements or tax returns. A steady three-year rise in EBITDA signals durable improvement, while one strong year after flat years often gets averaged down or discounted.

What happens if I have to sell my business unexpectedly?

An unplanned sale usually means selling on the buyer’s timeline, at whatever point your numbers happen to be, often with less leverage on price and terms. The Exit Planning Institute estimates that about half of US business exits are driven by unplanned events such as death, disability, divorce, distress or disagreement. Clean books, a capable management team and written contracts protect your value even if your exit comes sooner than planned, because buyers can still verify and trust the business.
