Preparing a Business for Sale: A 24-Month Roadmap

What Buyers, Lenders and Their Advisers Examine — and How Long Each Fix Takes

What Does Preparing a Business for Sale Involve?

Quick Answer: Preparing a business for sale means using the 24 months before you go to market to fix what a buyer’s diligence would otherwise find: an owner the business cannot run without, revenue concentrated in a few customers, records kept for tax filing rather than for a buyer, and a deal structure chosen after the price is agreed. The work is sequential, and most of it cannot be compressed into the final quarter.

This page describes no client result and states no figure for what preparation has produced, or may produce, for any business. Every number on it is attributed to the third party or the statute that published it. It is the preparation window in detail; the full arc from value creation through post-exit wealth sits on our business exit planning pillar.

The sequence below runs from 24 months out to closing. It is ordered the way diligence unwinds it, because the items a buyer questions last are usually the ones that took longest to build.

What Does the Evidence Actually Say About Seller Preparation?

There is no published figure for what preparation is worth, and this page will not invent one. No primary source reachable from this research publishes a measured price premium for prepared versus unprepared sellers, or a measured reduction in time to close. What the published data does show is how few owners have done the work, how long deals take, and what buyers and lenders are currently insisting on.

Source Population and period What it measures Figure
Exit Planning Institute, 2025 State of Owner Readiness (Generational) Analyses the 2023 National SOOR survey of 1,162+ U.S. business owners Owners with a formal exit plan 13%
Exit Planning Institute, 2025 (same survey) Baby Boomer, Generation X and Millennial owners Have assembled a full formal exit-planning advisory team (attorney, accountant, financial adviser, value-growth consultant) 5% / 11% / 32%
Exit Planning Institute, 2025 (same survey) Baby Boomer owners Have not completed a pre-transition value enhancement 78%
Exit Planning Institute, 2025 (same survey) U.S. private business owners generally Share of an owner’s total net worth the business can represent 80–90%
BizBuySell Insight Report, Q2 2026 2,117 closed U.S. small-business transactions, reported voluntarily by brokers; $1.8 billion total enterprise value Owners who have completed a professional valuation (50% hold a rough estimate; 35% report no idea) 14%
BizBuySell Insight Report, Q2 2026 Service businesses, 40% of all reported transactions Median days on market 155 days
BizBuySell Insight Report, Q2 2026 Manufacturing transactions Days to close, up 17% year over year 247 days
BizBuySell Insight Report, Q2 2026 Surveyed buyers and owners Buyers expecting to use SBA financing 78%
BizBuySell Insight Report, Q2 2026 Surveyed buyers and owners Buyers expecting seller financing, against owners planning to offer it 90% vs. 29%
IBBA & M&A Source Market Pulse, Q1 2026 56th edition; 300 advisers reporting 203 closed transactions, surveyed 1–16 April 2026 Deals above $5 million drawing at least three offers (18% drew ten or more) 83%

These are market-wide survey figures for small and lower-middle-market businesses over the periods stated. They describe those populations, not any individual business, and they are historical rather than predictive. Dew Wealth has not independently verified the survey methodology behind them.

Read the two datasets together and the gap is the point. Buyers are arriving with SBA prequalification and a diligence checklist, and 83% of lower-middle-market deals are drawing competing bids. Meanwhile the Exit Planning Institute puts owners with a formal exit plan at 13%, and BizBuySell puts those who have had the business valued at 14%. The preparation window is where that gap closes, or does not.

How Far in Advance Should You Start Preparing a Business for Sale?

Start when the changes you would need to make still have time to show a result. Most of the items a buyer prices — a management team that has actually been running the business, a customer list that has genuinely diversified, two years of financial statements prepared to a consistent standard — are only credible once they have a track record behind them. A decision made in the last quarter before going to market has no track record at all.

When to sell your business is a separate question from when to start preparing

The two get conflated, and it costs owners the preparation window. Timing the sale is a judgement about the business, the market and your own appetite. Preparing for it is work that has to happen regardless of which year you choose, and starting it does not commit you to selling. The Exit Planning Institute’s 2025 report found 58% of Baby Boomer owners planning to exit within five years while 5% had assembled a full advisory team — a gap that is about preparation, not about timing.

Is an external sale even the right exit?

Answer that before you spend two years preparing for one. The alternatives are a transfer to family or management and simply continuing to own the business, and each carries a different tax profile, a different timeline and a different definition of a good outcome. The trade-offs between an internal transfer and a third-party sale sit under business succession planning; the case for continuing to build instead, organically or through strategic acquisitions, is its own analysis. Most of the preparation work below raises the value of the business either way, which is why it is worth starting before the exit decision is final.

What if a buyer approaches before you are ready?

Unsolicited approaches happen, and they do not wait for your roadmap. The realistic answer is that an unprepared seller in that position has fewer options, not none: diligence will surface the same issues, but they get negotiated as price and terms rather than fixed in advance. Preparation is what converts a single interested party into a process with alternatives.

Months 24–18: What Should the First Six Months Cover?

The first six months produce information, not improvements. You cannot sequence work you have not measured, and every later decision on this roadmap depends on a baseline someone independent produced.

Workstream What it produces Why a buyer or lender cares
Independent business valuation A written baseline: current value range, comparable transactions, and the specific drivers holding the number down. See business valuation for how the methods differ. BizBuySell’s Q2 2026 survey found 14% of owners had completed a professional valuation. A baseline is also what makes any later improvement measurable.
Value-driver assessment An honest rating of the transferable attributes: earnings quality, growth, customer concentration, owner dependency, documented systems, differentiation, and reporting. These are the attributes diligence tests. Rating them early is what turns a two-year list into a sequence.
Advisory team, interviewed early A shortlist across four seats: M&A adviser or broker, transaction attorney, tax adviser, and the accountant who will carry the financials. Only 5% of Baby Boomer owners, 11% of Generation X and 32% of Millennials have a full team assembled (Exit Planning Institute, 2025). Interviewing early costs nothing and avoids hiring under time pressure.
A written sequence The improvement plan itself: which drivers, in which order, with an owner and a date against each. 78% of Baby Boomer owners have not completed a pre-transition value enhancement (Exit Planning Institute, 2025). A written sequence is the difference between intention and work.

Business broker or investment banker — which seat is this?

The distinction is mostly one of deal size and process. Brokers concentrate on Main Street transactions and typically run a lighter, faster process; M&A advisers and investment bankers work the lower middle market and run a structured auction with a longer buyer list. The IBBA and M&A Source Market Pulse survey splits its own reporting at exactly that line — Main Street at $0–$2 million and the lower middle market at $2–$50 million. Ask any candidate which of those two markets they closed in last year.

How Do You Reduce Owner Dependency Before a Sale?

Owner dependency is the risk that the business is really a job you built rather than an asset you can hand over. It shows up in diligence as questions about who holds the customer relationships, who prices the work, who the staff escalate to, and what happens in the first ninety days after closing. The fix is to move those things to other people and then let enough time pass that the move is demonstrable.

What actually transfers

Three things, in roughly this order: decision authority, relationships, and knowledge. Authority transfers when someone else can commit the business without checking. Relationships transfer when the customer calls that person first. Knowledge transfers when the method is written down in enough detail that someone unfamiliar could follow it. Each takes months, and the last one is usually the only one anybody documents.

Why customer concentration is treated as the same problem

Concentration and owner dependency are both single points of failure, and buyers underwrite them the same way. If one customer represents a large share of revenue, the question is not the percentage but the answer to two follow-ups: is the relationship contracted, and does it survive you leaving. Diversifying takes as long as it takes to win the replacement revenue, which is why it belongs in the first half of the roadmap rather than the second.

Owner dependency and customer concentration are two of the eight business value drivers a buyer prices. The other six, and what diligence asks about each, are set out there.

Months 18–12: Which Operational Improvements Do Buyers Price?

Months 18 to 12 are where the transferable improvements go, because they need a full operating year behind them before a buyer will credit them.

Improvement What “done” looks like What diligence asks
Management depth A named person other than the owner runs day-to-day operations and has done so long enough to have a track record under normal conditions. Who runs this if you are unavailable for a month? Has that already happened?
Customer diversification The largest customer’s share of revenue is falling because other revenue is growing, not because the largest account is shrinking. What is concentration by customer and by industry? Which relationships are contracted, and for how long?
Documented operating systems Sales, delivery and administration each have written procedures a new employee could follow, and staff actually use them. Show us the process for onboarding a customer. Now show us where that is written down.
Systems of record Customers, financials, projects and documents each live in a system rather than in spreadsheets and inboxes. Can you produce a clean customer list, an aged receivables report and a contract file without reconstructing them?
Key-employee retention The people a buyer needs to keep have a reason to stay through and past a transaction. Which employees are critical, what are they paid relative to market, and what holds them?

The right sequence here is specific to the business. This is the ordering logic we use with clients — longest-lead items first — not a prescription, and not advice about any particular company.

What Financial Records Do Buyers and Lenders Expect?

Buyers do not read your tax return the way your accountant does. They are trying to work out what the business earns on a normal, repeatable basis under a new owner, and every adjustment you ask them to accept is one they will test. Financial preparation is mostly the work of making that test easy to pass.

What is a quality of earnings review?

A quality of earnings review is an independent accounting analysis of whether reported earnings are sustainable and accurately stated — revenue recognition, one-time items, working-capital movements, related-party transactions. A buyer will commission one during diligence. A seller who commissions one first finds the same issues while there is still time to explain or fix them, rather than while price is being renegotiated.

Adjusted EBITDA, and which add-backs survive

Adjusted EBITDA is earnings before interest, tax, depreciation and amortisation, restated to remove items a new owner would not incur. The defensible ones are documented and genuinely non-recurring. Owner compensation above market is the most common add-back and the most scrutinised: the IRS’s own guidance on S corporation reasonable compensation (reviewed 3 March 2026) sets out the factors used to test what a role is worth — training and experience, duties, time devoted, what comparable businesses pay — and those are the same factors a buyer’s accountant will apply to the add-back.

Does a seller have to switch from cash to accrual accounting?

Usually not as a matter of tax law. Under IRC §448(c), a corporation or partnership meets the gross receipts test — and so escapes the required use of accrual accounting — if average annual gross receipts for the prior three-year period do not exceed $32,000,000 for taxable years beginning in 2026 (Rev. Proc. 2025-32, §3.30). The reason sellers convert anyway is comparability: accrual statements show a buyer when revenue was earned rather than when cash arrived, and lenders underwriting an acquisition generally expect them.

Why SBA eligibility belongs in the financial workstream

Because it determines who can bid. BizBuySell’s Q2 2026 report found 78% of surveyed buyers expecting to use SBA financing, and the SBA 7(a) programme caps a loan at $5,000,000 with “changes of ownership (complete or partial)” an express eligible use. Records that cannot support an SBA underwrite narrow the buyer pool to those paying cash or accepting seller paper — and the same survey found 90% of buyers expecting seller financing against 29% of owners willing to offer it.

Months 12–6: How Should the Sale Be Structured for Tax?

Structure is decided before the price is agreed, or it is decided for you. Several of the provisions below have holding periods or elections that cannot be created retroactively, which is the whole reason this band sits at twelve months out rather than three.

Provision What it does Why the timing matters Source
Qualified small business stock Excludes gain on the sale of qualifying C corporation stock acquired at original issue, subject to a per-issuer cap and the other §1202 tests. Two tracks now run in parallel under IRC §1202. Stock acquired on or before 4 July 2025 keeps the original IRC §1202 rules: a five-year holding period, a cap of the greater of $10,000,000 or ten times basis, and a $50,000,000 corporate gross-asset ceiling. Stock acquired after 4 July 2025 follows the schedule Public Law 119-21 added to IRC §1202: 50% at three years, 75% at four, 100% at five, a cap of the greater of $15,000,000 (indexed from 2027) or ten times basis, and a $75,000,000 gross-asset ceiling. IRC §1202(a), (b), (d)
Installment sale Spreads gain over the years payments are received, rather than taxing all of it at closing. An installment sale is any disposition where at least one payment arrives after the close of the tax year of sale. Recapture income under §1245 or §1250 is still recognised in full in the year of disposition, and a taxpayer may elect out. The seller-financing data above is why this comes up so often. IRC §453(a), (b)(1), (c), (d), (i)
Asset sale vs. stock sale Decides who bears which tax and what the buyer’s basis becomes. In an applicable asset acquisition, consideration is allocated among the assets by the residual method, both parties report the allocation, and a written allocation agreed between them is binding unless the IRS finds it inappropriate. Buyers generally prefer assets; sellers of C corporation stock generally do not. This is a negotiation, and it is cheaper before a letter of intent than after. IRC §1060(a)–(c)
Entity and residency questions Determines the state that taxes the gain and, in some structures, whether an election is even available. State treatment varies and several planning steps have look-back periods measured in months or years. Whether any of it applies to a particular owner is a question for that owner’s tax adviser, on that owner’s facts. State law; varies

Dew Wealth is not a law firm or an accounting firm, and nothing here is an opinion on the treatment of any particular transaction. Deeper treatment of the exit-tax questions sits on selling a business tax strategies.

Months 6–0: From Going to Market Through Closing

The last six months are execution. The preparation is finished by now, or it is not, and the process simply reveals which.

Window What happens What it depends on having already been done
Months 6–3: going to market The confidential information memorandum is written, the data room is assembled, the buyer list is built across strategic, financial and individual buyers, and the adviser is formally engaged. A confidential information memorandum is a summary document, not a sales brochure: everything asserted in it will be tested. It can only be written from records that already exist.
Months 3–1: marketing and the letter of intent Approaches under non-disclosure, management presentations, initial offers, and negotiation of the letter of intent — price, structure, earnout, exclusivity. Competitive tension. The IBBA and M&A Source Market Pulse found 83% of deals above $5 million drew at least three offers in Q1 2026; a single bidder negotiates differently from three.
Month 0: diligence and closing Financial, operational, legal and customer diligence; the purchase agreement; resolution of what diligence surfaced; approvals and closing. Sell-side diligence done in advance. Issues found by your own accountant get explained; the same issues found by the buyer’s get priced.

How long does the last stretch actually take?

Longer than most owners plan for, and it varies by sector. BizBuySell’s Q2 2026 Insight Report put median days on market at 155 days for service businesses — the largest segment, at 40% of reported transactions — while manufacturing transactions took 247 days to close, 17% longer than a year earlier. Those are medians across reported small-business transactions, not a forecast for any particular sale.

Why Do Prepared Sales Close When Unprepared Ones Stall?

Because the failure points are known in advance and there are only a handful of them. A deal stalls when diligence produces a surprise, when financing falls through, or when the buyer concludes the business does not survive the owner’s departure. Preparation is the work of removing those three, and it is the reason the same brokers who report a slower market also report intense competition for the businesses that are ready.

What the brokers in the Q2 2026 survey actually said

Two observations from BizBuySell’s Q2 2026 Insight Report are worth quoting because they describe the mechanism rather than the outcome. Vipin Singh of Murphy Business Sales described “preparation, clean financials, and minimized owner dependence” as prerequisites to closing. On financing, Singh added that failing an SBA underwriting check “doesn’t make a business unsellable, but it shifts the transaction from a competitive, bank-leveraged sale into one heavily reliant on seller concession and structured financing.” Those are broker opinions reported in a survey, not measured outcomes.

The honest limit of all of this

Preparation improves the odds and the terms available to you. It does not set a price, it does not guarantee a sale, and no source cited on this page measures what it is worth in dollars for a business of any given size. Anyone quoting you a specific percentage uplift from preparation should be asked which study it comes from.

What Are the Most Common Sale-Preparation Mistakes?

These are the recurring ones. Each is stated with the control that prevents it, because a mistake without a control is just a warning.

Mistake Why it costs The control
Starting three to six months out Nothing you change in that window has a track record, so a buyer discounts it as an intention rather than crediting it as an improvement. Begin the assessment at least 24 months out. Starting does not commit you to selling, and the assessment is useful whether you sell or keep.
Treating owner dependency as a soft issue It is the one attribute that determines whether there is a transferable asset at all. Move authority, relationships and knowledge to named people, and let a full operating year pass so the transfer is demonstrable.
Records built for tax filing only Diligence stalls while your accountant reconstructs history, and every reconstruction invites a question. Consistent statements for the final two years, a sell-side quality of earnings review, and documented support for every add-back.
Deciding structure after price Several provisions have holding periods or elections that cannot be created retroactively. Take the structure question to your tax adviser at twelve months out, before a letter of intent constrains the answer.
Ignoring how the buyer will pay 78% of surveyed buyers expect SBA financing and 90% expect seller financing, against 29% of owners willing to offer it (BizBuySell, Q2 2026). Have the business reviewed against SBA eligibility early, and decide your own position on seller financing before it is asked in negotiation.
Waiting for a better year Postponement is a decision with its own risk: markets, health and energy all change while you wait. Separate the timing decision from the preparation decision. Prepare on a schedule; decide on timing when the preparation is done.

Preparing a Business for Sale: Frequently Asked Questions

How long does it take to sell a business?

Longer than most owners expect, and it varies by sector. The BizBuySell Insight Report for Q2 2026 put median days on market at 155 days for service businesses, the largest segment at 40% of reported transactions, while manufacturing transactions took 247 days to close, 17% longer than the year before. Those medians cover the marketing and closing period only. The preparation that precedes going to market is separate, and is the 24 months this page describes.

What is a quality of earnings review, and does a seller need one?

A quality of earnings review is an independent accounting analysis of whether reported earnings are sustainable and accurately stated: revenue recognition, one-time items, working-capital movements and related-party transactions. A buyer will commission one during diligence regardless. A seller who commissions one first finds the same issues while there is still time to explain or correct them, rather than while price is being renegotiated.

What is adjusted EBITDA, and which add-backs survive diligence?

Adjusted EBITDA is earnings before interest, tax, depreciation and amortisation, restated to remove items a new owner would not incur. Add-backs that survive are documented and genuinely non-recurring. Owner compensation above market is the most common and the most tested: the IRS factors for S corporation reasonable compensation, reviewed 3 March 2026, include duties, time devoted, and what comparable businesses pay for similar services, and a buyer's accountant applies the same factors.

Does a business have to switch from cash to accrual accounting before a sale?

Usually not as a matter of tax law. Under IRC section 448(c), a corporation or partnership meets the gross receipts test, and so escapes required accrual accounting, if average annual gross receipts for the prior three-year period do not exceed $32,000,000 for taxable years beginning in 2026, per Rev. Proc. 2025-32. Sellers often convert anyway, because accrual statements show a buyer when revenue was earned and lenders generally expect them.

Does the five-year QSBS holding period still apply?

It depends on when the stock was acquired, and both tracks are live under IRC section 1202. Qualified small business stock acquired on or before 4 July 2025 keeps the original IRC section 1202 rules: five years, a cap of the greater of $10,000,000 or ten times basis, and a $50,000,000 gross-asset ceiling. Stock acquired after that date follows the schedule added by Public Law 119-21: 50% excluded at three years, 75% at four and 100% at five, with a $15,000,000 cap indexed from 2027 and a $75,000,000 ceiling. Verify against IRC section 1202 with your tax adviser.

How do the wealthiest families
prepare a company for sale?

On a schedule, starting long before there is a buyer, with one team coordinating the valuation, the operating improvements, the financial records and the structure rather than four advisers meeting for the first time in diligence. Schedule an assessment and we will walk your own timeline with you: what the preparation window would need to cover, in what order, and which items on it have lead times you cannot compress.
