Preparing a business for sale: start three years out, and don't list until this checklist is done
Here is the advice I give almost every owner who calls me about selling: start about three years before you want to be gone, and do not put the business on the market until the items in this article are handled. Not most of them. All of the ones that apply to you.
That can sound like a broker slowing down his own paycheck. It is the opposite. A business listed before it is ready gets low offers, gets retraded or dies at the lender. I would rather list your business once, ready, than twice.
Why three years
Buyers and lenders look backward before they look forward. They want to see several years of financial history, and they want the most recent years to be the cleanest and strongest. If you fix your books, hire a manager or sign a new lease six months before you list, a buyer sees one good stretch and a lot of history that tells a different story. Fix them three years out and the change is the history.
Three years also gives you room for what you cannot rush: training someone to do what you do, getting a landlord to extend a lease, letting a new system settle in, and deciding what you want after the sale.
You are not alone in thinking about this. In the Exit Planning Institute's 2023 National State of Owner Readiness survey of more than 1,100 owners, 49% said they wanted to exit within five years and 75% within ten (EPI report). A lot of businesses are going to come to market. The prepared ones will stand out.
Clean books
Every serious buyer starts with the numbers, and every number will be checked. Clean books are the foundation everything else sits on.
Cash or accrual
Many small businesses keep books and file taxes on the cash method, which the IRS allows for many small businesses (IRS Publication 538). But cash-basis statements can make a month or a year look better or worse than it was, depending on when customers paid and when you paid bills. Buyers and their accountants often want an accrual view. Ask your CPA whether accrual books, or accrual-adjusted statements alongside your tax filings, make sense. Starting now beats rebuilding three years of history later.
Separate personal and business
Run personal spending through the business and you create two problems. Your profit looks lower than it really is, and every one of those expenses becomes an argument in diligence. The cleanest fix is to stop. If you keep some owner perks running through the business, track every one in its own account so it can be added back later with a receipt behind it.
Add-backs you can prove
Add-backs are expenses that will not continue under a new owner, like your salary, your personal vehicle or a one-time legal bill. They can add real value. But an add-back with no paper behind it is just a claim, and buyers and lenders discount claims. Keep a running add-back schedule with the amount, the reason and the document for each item.
Three years of tax returns that match your P&Ls
This one is not optional if your buyer is using SBA financing, and many main street buyers do. Under SBA's SOP 50 10 8.1, for a change of ownership the lender must verify the seller's financial data against IRS tax transcripts and reconcile any discrepancies before the loan is disbursed (SOP 50 10 8.1, section A.Ch5.B, verbatim text; SBA's SOP page). In plain terms: if your P&L says you made $400,000 and your tax return says $150,000, the lender is going to lend against the tax return.
"I made more than I reported" is not a selling point. Make sure your returns and your internal statements tell the same story for at least three years before you list.
Monthly P&Ls and balance sheets
Annual numbers are not enough. A buyer will want to see trailing twelve months, seasonality and the trend right up to the day they make an offer. That means closing your books every month: a profit and loss statement and a balance sheet, reconciled to the bank, done within a few weeks of month end.
The balance sheet matters more than owners think. It shows receivables, payables, inventory and debt, and it drives the working capital conversation later in the deal.
Recast financials and SDE
Once the books are clean, they can be recast. Recasting means adjusting the statements to show what the business earns for an owner, which for most main street businesses is Seller's Discretionary Earnings (SDE): pre-tax profit plus one owner's salary and benefits, interest, depreciation, amortization and documented one-time or personal expenses.
SDE is the number most small business prices are built on. The IBBA and M&A Source Market Pulse survey expresses deals under $2 million as multiples of SDE and larger deals as multiples of EBITDA (IBBA Q2 2026 highlights). Getting your recast right, with every adjustment supported, is how you defend your price. If you want to see how the math works in detail, read What is my business worth?
SOPs, systems and key employees
Written SOPs
A buyer is paying for a business that keeps working after you leave. Written standard operating procedures are the proof. They do not need to be fancy. A checklist for opening and closing, a step-by-step for quoting a job, how you order inventory, how you onboard a new hire, how you bill and collect. If a key task only exists in your head, it is a risk the buyer will price in.
Systems and CRM
Customer lists in a notebook and jobs scheduled by text message do not transfer well. Put customers, quotes, jobs and follow-ups into a CRM or field service system, and make sure the data belongs to the business, not your personal accounts.
Key employees
Buyers will ask who really runs things and whether those people will stay. Identify your two or three most important employees. Pay them fairly, give them real responsibility, and think about whether a stay bonus tied to a sale makes sense. If one person's departure would cripple the business, that is a problem to solve now, not during a buyer's site visit. Owner dependence is a big enough issue that I wrote a separate article on it: Owner-dependent businesses sell for far less.
Customers, contracts, leases and licenses
Customer concentration
If one customer is a big share of your revenue, a buyer sees a business that could lose a large piece of its income with one phone call. Spend the runway growing other accounts, putting important customers under written agreements, and building recurring revenue like service plans or maintenance contracts.
Contracts and assignability
Pull every important contract: customers, suppliers, franchise agreements, equipment leases, software. Read the assignment and change-of-control language. Some contracts can be transferred to a buyer freely. Others need consent. Some terminate on a sale. You want to know which is which before a buyer's attorney tells you.
Your lease
For many main street businesses the lease is one of the most important assets in the deal. A buyer's lender will typically want the lease term, with options, to line up with the loan. Check how many years you have left, whether there are renewal options, and what the landlord requires to approve an assignment. Start that conversation early. Landlords do not move on your timeline.
Licenses and permits
Make a list of every license, permit and certification the business operates under, and note whose name it is in. If the business runs on your personal contractor's license or professional license, a buyer needs a plan for how that gets replaced, and that plan can take time.
Legal cleanup
- Corporate records up to date: annual filings, ownership records, operating agreement or bylaws
- Any lawsuits, claims or disputes resolved or clearly documented
- Liens and UCC filings checked and cleaned up
- Payroll and sales tax filings current
- Employees correctly classified, with written agreements where needed
- Intellectual property, domain names and social accounts owned by the business
Your attorney and CPA should be part of this. Bring them in years before the sale, not the week before closing.
What buyers and SBA lenders will ask for in diligence
Once there is a signed letter of intent, expect requests like these. Having them ready before you list is the single best way to keep a deal on schedule.
- Three years of business tax returns, plus year to date financials
- Monthly P&Ls and balance sheets for the trailing period
- Bank statements to support revenue
- Add-back schedule with documentation
- Customer list with revenue by customer (shared late and carefully)
- Lease, contracts, licenses and permits
- Employee list with roles, pay and tenure
- Equipment and inventory lists
- Insurance, litigation and tax compliance records
On SBA-financed deals, the lender also orders an independent business valuation, and if the price is higher than the valuation supports, the gap generally has to be covered with more buyer equity rather than more debt (Womble Bond Dickinson on SOP 50 10 8.1). Clean, documented numbers are what hold your price through that review. More on that in Selling to an SBA-financed buyer.
The three-year exit readiness timeline
| When | Focus | What gets done |
|---|---|---|
| Year 1 (36 to 24 months out) | Baseline and books | Get a baseline valuation. Separate personal and business spending. Start monthly closes. Talk to your CPA about accrual statements. Start the add-back schedule. Write down everything only you do. |
| Year 2 (24 to 12 months out) | Build the asset | Hire or promote a manager and hand off key tasks. Write SOPs. Move customers and jobs into a CRM. Work on customer concentration and recurring revenue. Review contracts for assignability. Open lease talks. |
| Year 3 (12 to 0 months out) | Prove it and package it | Keep revenue and margins steady or rising. Finish legal cleanup. Assemble the diligence folder. Recast financials and confirm SDE. Decide on your price range, deal terms and transition role. Then list. |
Even after you list, plan for time. The IBBA and M&A Source survey for Q2 2026 found main street deals averaged six to 10 months from engagement to close (IBBA Market Pulse Q2 2026). Preparation is how you land on the short end of that range.
What happens if you list too early
Low offers
Buyers price risk, and messy books, owner dependence and unread contracts all read as risk. BizBuySell's Q3 2026 report said buyers are gravitating toward businesses with reliable cash flow, clean financials, limited owner dependence and a clear path to financing (BizBuySell Insight Report). If your business does not look like that, you are competing on price.
Retrades
A buyer signs a letter of intent at a number, then diligence turns up add-backs that cannot be proven, a lease that is about to expire or a customer who is leaving. The price comes down, often late, when you are emotionally committed and have already told your family it is done.
Deals that die in diligence
Missing records, unresolved legal issues or a key employee who walks can end a deal after months of work. And a business that failed to sell once is harder to sell the second time.
SBA financing problems
If your tax returns do not support the earnings you are asking a buyer to pay for, the lender's verification and valuation will expose it. The loan gets cut, the buyer cannot cover the gap, and the deal either falls apart or you end up carrying more of the price yourself.

FAQ
When is the right time to sell my business?
When the business is ready and you are ready, which usually means starting preparation about three years ahead. The best time is often when earnings are steady or rising, not after a down year or when you are burned out.
How long does it take to prepare a business for sale?
It depends on where you start. Owners with clean books and a strong team may need a year. Owners who are the center of everything, with mixed personal and business finances, usually need two to three years to show a track record buyers and lenders will trust.
Do I need three years of tax returns to sell my business?
Buyers will expect them, and SBA lenders verify the seller's financial data against IRS tax transcripts on change of ownership loans. If your business is younger than three years, expect the lender to look at all the years you have.
Should I switch to accrual accounting before selling?
Ask your CPA. Many small businesses file taxes on the cash method, but buyers often want an accrual view of the numbers. Producing accrual-basis statements alongside your tax filings is a common middle ground.
Can I sell my business if it depends on me?
Often yes, but it will usually sell for less and on tougher terms. Reducing owner dependence is one of the highest-value projects in an exit plan.
