Preparing a business for sale means making your financials something a stranger can trust. So buyers check three years of consistent statements, whether earnings are real and repeatable, how much cash the business needs, and how much depends on you. But we advise starting at least a year before you want to sell.
So this guide covers what buyers look at, how valuation works, what add-backs are, and a timeline to follow. It is general information, not legal or tax advice, so bring your CPA and attorney in early.
What Do Buyers Look at in Your Financials?
Buyers do not pay for revenue alone. They pay for earnings they can verify. So the table shows what they check and how to prepare.
| What Buyers Check | The Question Behind It | How to Prepare |
| Three years of statements | Do the numbers tie out and follow one method? | Report on an accrual basis and close the books every month |
| Quality of earnings | Are the profits real and repeatable? | Document one-time items and owner expenses |
| Customer and revenue mix | Does one customer or job type carry the business? | Report revenue by customer and by service line |
| Margins by line | Where does the profit actually come from? | Track gross margin by job type or product |
| Working capital | How much cash does the business need to run? | Clean up aged receivables and slow inventory |
| Debt and obligations | What comes with the business? | List every loan, lease, and commitment |
| Owner dependence | What happens when the owner leaves? | Document processes and build a second layer of management |
Not every item carries the same weight, however. In our experience, earnings quality and owner dependence draw the most questions, so start there.
How Do Buyers Value a Business?
The SBA lists three common approaches in its guidance on how to close or sell your business. First, the income approach looks at projected revenue and accounts for risk. Second, the market approach compares your business to similar businesses that recently sold. Third, the assets approach subtracts total liabilities from the value of all assets.
Every approach starts with your numbers, because projected revenue, comparable margins, and the balance sheet all come from your financial statements. Valuation itself is a job for a qualified appraiser or advisor, so this guide covers the financial preparation that feeds it.
What Are Adjusted Earnings and Add-Backs?
Adjusted earnings, often called adjusted EBITDA, are reported earnings after you remove one-time items and owner-specific costs, so a buyer sees what the business earns without you. First, EBITDA means earnings before interest, taxes, depreciation, and amortization. Second, an add-back is a cost you add back to earnings because a new owner would not incur it.
Adjustments run both ways. The example below uses invented numbers. A one-time repair and personal expenses run through the business raise adjusted earnings, but a market-rate manager’s salary lowers them, because the buyer must pay someone to do your job.
| Line | Amount |
| Reported operating profit | $400,000 |
| Add: one-time storm repair | $40,000 |
| Add: personal vehicle and travel run through the business | $24,000 |
| Less: market salary for a replacement manager | ($60,000) |
| Adjusted earnings | $404,000 |
Buyers test every adjustment. So each one needs support: an invoice, a contract, or a clear written explanation. But if you cannot document an add-back, it usually comes out of the price.
Why Does Accrual Accounting Matter to a Buyer?
Accrual accounting records revenue when you earn it and costs when you incur them, so each month shows what actually happened. However, the SBA notes that GAAP standardizes financial reporting on the accrual method, and that GAAP is optional for private companies. In our experience, buyers and their lenders still expect consistent accrual-basis statements.
But if your books run on a cash basis, the switch takes time. Our post on cash versus accrual accounting also explains the difference. A disciplined close also keeps the books current, as we describe in How the Monthly Financial Close Process Works.
How Far Ahead Should You Start Preparing a Business for Sale?
We advise at least a year. Start earlier if your books need cleanup. This timeline is our view, so adjust it with your advisors.
| Months Before Listing | Focus | What to Finish |
| 24 to 12 | Clean books | Move to accrual reporting, run a monthly close, and reconcile every account |
| 12 to 6 | Prove the earnings | Document add-backs, review customer concentration, and clean aged receivables and slow inventory |
| 6 to 0 | Package and advisors | Assemble the buyer-ready package and line up your CPA, attorney, and broker or appraiser |
Because the books need several clean months to prove the pattern, starting early matters more than starting perfectly.
What Belongs in a Buyer-Ready Financial Package?
So a complete package answers a buyer’s questions before they ask.
- Three years of financial statements and tax returns
- Monthly statements for the current year
- Accounts receivable and accounts payable aging reports
- A debt schedule listing every loan, lease, and commitment
- A schedule of adjustments, with support for each one
- Revenue and margin by customer and by service line
- A forecast for the next 12 months
Profit and cash are different measures, and buyers study both, so our guide to the difference between profit and cash flow explains why.
Then keep the package current, because a stale package invites doubt.
What Does a Fractional CFO Do When You Are Preparing a Business for Sale?
A fractional CFO builds the monthly close, the schedule of adjustments, and the forecast, then sits at the table when a buyer’s team asks questions. Our founder has performed financial due diligence on transactions from $25 million to $1.1 billion, so we know which questions buyers ask and where sellers get caught. But we work alongside your CPA, attorney, and broker, not in place of them.
Timing matters here more than anywhere. So our post on the cost of waiting to hire a fractional CFO explains why starting early protects the price. To see how an engagement works, read about our recurring partnership. Finally, for a primer on the role, start with What Is a Fractional CFO (And Does Your Business Need One)?.
| Westport Insight: A buyer discounts what it cannot verify. The work that protects your price is plain: a monthly close, documented add-backs, and clean receivables. Owners who start that work a year early walk into diligence with answers instead of explanations. |
Frequently Asked Questions
How early should I start preparing a business for sale?
We advise at least a year before you want to sell, but longer if your books need cleanup. So that gives you time to run several clean monthly closes and document your adjustments.
What do buyers look at in a company’s financials?
Three years of consistent statements, quality and repeatability of earnings, revenue and customer mix, margins by line, working capital, debt, and how dependent the business is on the owner.
What are adjusted earnings or adjusted EBITDA?
Reported earnings after removing one-time items and owner-specific costs, so a buyer sees what the business earns without you. Every adjustment needs support. EBITDA means earnings before interest, taxes, depreciation, and amortization.
What is a quality of earnings review?
An analysis, often commissioned by a buyer, that tests whether reported earnings are accurate and repeatable. Clean monthly books also make the review faster and less stressful.
Do I need accrual-basis books to sell my business?
The SBA notes that GAAP is optional for private companies, but in our experience, buyers and their lenders still expect consistent accrual-basis statements, because they show each month’s real results.
How do buyers value a business?
The SBA lists three common approaches: income, market, and assets. The income approach uses projected revenue and risk, the market approach compares recent sales of similar businesses, and the assets approach subtracts liabilities from assets. So a qualified appraiser should do the valuation.
Can a fractional CFO help me prepare a business for sale?
Yes. A fractional CFO builds the monthly close, the schedule of adjustments, and the forecast, and also works alongside your CPA, attorney, and broker. But it is not a substitute for those advisors.
The Bottom Line
Preparing a business for sale is mostly a financial reporting project, because buyers pay for earnings they can verify. So the job is to make your numbers consistent, supported, and current.
Start with the timeline above, then add your CPA and attorney early. The earlier you begin, the more of the work becomes routine instead of a scramble.
