A great business at the wrong price is still a bad deal. Most first-time buyers move straight from “I like this business” to “let’s make an offer” without answering the two questions that actually decide whether the purchase works: what the business is worth, and how the deal is structured.
This post covers how to buy a small business from the financial side: how to value one, how financing shapes what you can afford, which deal terms protect you, and where a Fractional CFO fits into the process.
How Much is a Small Business Actually Worth?
Most smaller businesses (especially service businesses) are valued using a multiple of Seller’s Discretionary Earnings (SDE), not revenue and not EBITDA. SDE adds back the owner’s salary, personal expenses run through the business, and one-time costs to the pre-tax profit, giving you a number that represents what the business can pay a new owner-operator. The buyer will also normalize for expenses if the current owner is paying more than industry average such as for labor, materials, etc.
The multiple you apply to SDE depends on size, industry, growth trend, and how dependent the business is on the current owner. Very small, owner-operated businesses commonly trade at lower multiples than mid-size companies with a management team already in place, because a buyer has to replace the owner’s labor, not just buy an income stream.
SBA-financed deals also often close at lower multiples than deals backed by private equity or search-fund capital, since SBA lenders underwrite conservatively on debt service coverage. If a broker or seller quotes a multiple, ask what earnings figure it’s applied to and who normalized it. Read the IRS guidance on business valuation factors if you want to understand how regulators scrutinize add-backs; it’s the same logic a lender or buyer could apply.
How to Buy a Small Business: Build Your Deal Team Before You Make an Offer
The deal team should be in place before you sign a letter of intent, not after. Waiting until financing falls through or a tax issue surfaces mid-diligence costs time you don’t get back.
- CPA or Fractional CFO: normalizes the financials, tests the seller’s numbers against tax returns and bank statements, and models cash flow under your ownership.
- Attorney: drafts and negotiates the purchase agreement, including indemnification and non-compete terms.
- Lender: pre-qualifies you for financing before you’re under contract, so your offer is credible.
A Fractional CFO earns their fee in this phase alone: they’ll catch add-backs that don’t hold up, model your actual debt service coverage, and tell you honestly whether the price fits your cash flow before you’re emotionally committed to the deal.
How to Buy a Small Business with SBA Financing: What You Can Actually Afford
Many individual buyers finance small business acquisitions with an SBA 7(a) loan, which currently caps at $5 million per loan. The program currently requires a minimum equity injection, generally around 10% of total project cost, calculated on the full purchase price plus working capital and fees, not just the purchase price alone. Lenders also look hard at cash flow. Under SBA’s updated rules (SOP 50 10 8.1), which apply to applications numbered on or after October 1, 2026, most change of ownership deals now need a debt service coverage ratio of at least 1.25x, up from 1.15x.
Rates on 7(a) acquisition loans are variable, priced off the prime rate plus a lender spread, and have moved with the broader rate environment. Timelines commonly run 45 to 90 days from application to funding, which is why financing pre-qualification should happen before you’re under a tight closing deadline in a purchase agreement.
| SBA 7(a) Feature | What Buyers Should Know |
|---|---|
|
Max loan amount |
$5 million per 7(a) loan; combined with a 504 loan, cumulative SBA-backed financing can reach $10 million. |
|
Equity injection |
Typically around 10% of total project cost for a full change of ownership. |
|
Rate structure |
Variable, tied to prime plus a lender spread; confirm current rates with your lender since prime moves. |
|
Timeline |
Roughly 45 to 90 days from application to funding. |
|
Seller financing |
Often layered in alongside SBA debt when buyer equity or debt service coverage is tight. Seller notes and other limited sources can cover no more than half of the required equity injection, and a seller note generally has to stay on full standby. |
Deal Structure Terms That Protect You as the Buyer
The purchase price is one number in the agreement. The terms around it decide how much risk you’re actually taking on.
- Holdbacks: a portion of the purchase price is held in escrow for a set period to cover any post-closing issues that surface, like an unrecorded liability.
- Indemnification clauses: spell out what the seller is responsible for if a problem, like a prior lawsuit or tax liability, shows up after closing.
- Earnouts: tie part of the price to the business hitting performance targets after you take over, which shifts some risk back to the seller.
- Working capital adjustments: set a target working capital level at closing so you’re not left funding a shortfall the seller drew down before handing over the keys.
Whether the deal is structured as an asset purchase or a stock purchase changes which of these terms matter most. In a stock purchase, you take on the entity’s contracts and liabilities, so indemnification and holdbacks matter even more. In an asset purchase, you choose which assets you take on, which generally leaves more liabilities with the seller. Talk through the right structure with your attorney and CPA before you sign a letter of intent.
The Acquisition Timeline: From Offer to Closing
A typical small business acquisition moves through five stages, though timing varies by deal complexity and financing source.
- Letter of intent (LOI): outlines price, structure, and exclusivity, usually non-binding on price.
- Due diligence: financial, legal, and operational review, typically 30 to 60 days.
- Financing commitment: lender issues a formal commitment letter once underwriting is complete.
- Purchase agreement: final legal document with all negotiated terms, including indemnification and holdbacks.
- Closing and transition: funds transfer, ownership changes, and the operational handoff begins.
Due diligence and financing often run in parallel rather than back to back, which is one reason having your lender and CFO engaged early shortens the overall timeline.
Common Mistakes First-Time Buyers Make
- Valuing the business on revenue instead of normalized SDE or EBITDA.
- Underestimating post-close working capital needs, then funding a cash crunch out of pocket in month one.
- Starting the financing conversation after signing the LOI instead of before.
- Accepting the seller’s financials without reconciling them to tax returns and bank statements.
- Going through the entire process without an advisor who models cash flow under your ownership, not the seller’s.
Thinking About Buying a Business?
Where a Fractional CFO Fits Into a Business Purchase
Before you buy, a Fractional CFO builds the cash flow model that tells you whether the price, the financing terms, and your personal draw all fit together, before you’re locked into a purchase agreement.
After you buy, that same CFO helps you integrate the acquired business’s books, reset budgets around your actual debt service, and catch the early warning signs if performance is tracking below what you underwrote. That continuity, the same person modeling the deal and then managing the numbers after close, is where a lot of value gets protected.
Our bookkeeping and tax teams support that transition once the deal closes, so the financial infrastructure is ready on day one of ownership.
Frequently Asked Questions
How much does it cost to buy a small business?
Cost depends on the business’s normalized earnings (SDE) and the multiple applied, which varies by industry, size, and growth trend. There’s no fixed price per employee or per year of revenue; two similar-looking businesses can carry very different valuations based on customer concentration, owner dependence, and financial documentation quality.
What's a good multiple to pay for a small business?
There’s no single correct multiple. It depends on the earnings base, industry, and financing source, and multiples paid by SBA-financed individual buyers commonly run lower than multiples paid by private equity or search-fund buyers. Get a basic calculation from a valuation specialist with an ABV or CBV credential rather than relying on a rule of thumb.
Can I use an SBA loan to buy an existing business?
Yes. The SBA 7(a) program is the most common financing route for individual buyers acquiring an existing small business, with a $5 million loan cap and a minimum equity injection requirement, generally around 10% of total project cost.
How long does it take to buy a small business?
From signed letter of intent to closing, plan on roughly two to four months, factoring in 30 to 60 days of due diligence and 45 to 90 days for SBA financing to fund, with some of that time running in parallel.
Do I need a CPA or CFO to buy a business?
You don’t legally need one, but skipping this step is one of the most common first-time buyer mistakes. A CPA or Fractional CFO reconciles the seller’s numbers, models your cash flow post-close, and often pays for their fee many times over by catching issues before you’re contractually committed.
What is seller financing, and how common is it?
Seller financing means the seller carries a note for part of the purchase price, repaid by the buyer over time. It’s frequently layered alongside SBA financing when buyer equity or debt service coverage is tight, and it can also signal the seller’s confidence in the business’s future performance.
What's the difference between buying assets and buying stock?
An asset purchase lets you buy specific assets and generally leaves most liabilities with the seller’s entity. For buyers, the assets are valued at the fair market value you purchased them for leading to a higher short term depreciation opportunity compared to the lower book cost on the seller’s books. A stock purchase means you acquire the entire entity, including its existing contracts, liabilities, and history.
For sellers, a stock sale commonly allows all or most of the gain to be treated as capital in nature with a reduced tax rate compared to a sale of assets which may trigger a significant gain at higher ordinary income (marginal) tax rates. The right structure depends on your risk tolerance, tax position, and whether the business holds contracts that are hard to transfer.
