Why Acquisitions Are So Financeable
Financing the purchase of an existing business is often easier than financing a startup, and the reason is simple: you are buying proven cash flow. A lender looking at a startup sees a projection. A lender looking at an acquisition sees years of tax returns, real customers, and a track record of the business actually paying its bills.
That history is collateral of a kind. If the business has generated consistent earnings for the last three years, a lender can underwrite the loan against those earnings rather than against a hope. This is why a first-time owner with limited assets can sometimes buy a $1 million business with a modest amount of cash down, something that would be impossible if they were building the same business from scratch.
The whole game, then, is proving two things: that the business is worth what you are paying, and that its cash flow can comfortably cover the loan payment after you take over. Everything below is in service of those two questions.
The SBA 7(a): The Acquisition Workhorse
For most small-business acquisitions under $5 million, the SBA 7(a) loan is the default tool, and for good reason. It offers long terms, capped rates, and a relatively low equity requirement, which is exactly what a buyer needs when most of the purchase price is goodwill rather than hard assets.
A few features make it fit acquisitions well:
- Loan size up to $5 million, enough for the large majority of small-business deals.
- A typical equity injection of around 10% of the total project cost. That down payment can come from your own cash, and in many cases part of it can come from a seller note on standby (more on that below).
- Terms up to 10 years for a business without real estate, which spreads the payment out and keeps it serviceable from the business's own earnings.
- A rate structure of the prime rate plus a capped spread that varies by loan size, so a strong deal is protected from the highest end of the market.
The elegant part is that the acquired business services its own debt. You are not paying the loan out of your salary; the earnings you are buying cover the payment. To see how a given loan amount, rate, and term translate into a monthly figure, run the numbers through the SBA loan calculator.

Seller Financing, Standby Notes, and Earnouts
Rarely is an acquisition funded by a single loan. The most common structure blends bank or SBA debt with money the seller is willing to leave in the deal, and understanding that blend is what separates a deal that closes from one that stalls.
Seller financing means the seller accepts part of the price as a promissory note you pay off over time, typically covering 10% to 30% of the purchase. Sellers agree to it more often than you would expect, because it signals their confidence in the business and often gets them a higher total price. It also aligns their interests with yours during the transition.
Standby notes are the SBA-specific wrinkle worth knowing. On an SBA 7(a) acquisition, a portion of your required equity injection can be satisfied by a seller note only if that note is on full standby, meaning the seller receives no payments (sometimes not even interest) for a set period, commonly the first two years. A standby note lets a buyer who is short on cash still meet the equity requirement, while the bank's exposure stays covered.
Earnouts tie part of the price to the business hitting agreed targets after the sale. They are useful when buyer and seller disagree on what the business is really worth: the seller earns the extra money only if the optimistic numbers materialize. Earnouts are more common in larger or conventionally financed deals than in standard SBA transactions, but they are a helpful tool for bridging a valuation gap.
Conventional Acquisition Loans
The SBA is not the only path. For larger deals, asset-heavy businesses, or exceptionally strong buyers, a conventional bank acquisition loan can be faster and free of the SBA guarantee fee and paperwork.
Conventional acquisition financing tends to make sense when the target has substantial hard assets a bank can lend against, when the buyer brings significant industry experience and a large down payment, or when the deal size exceeds what the SBA comfortably handles. The trade-offs are usually a larger required down payment, shorter terms, and stricter cash-flow requirements. If you are weighing the two paths, the differences in rate, term, and paperwork mirror those covered in our comparison of SBA versus conventional financing, and the right answer depends mostly on the size and asset profile of the business you are buying.
Valuation and Due Diligence
No lender funds an acquisition on the buyer's word that the price is fair. They require independent proof, and you should want it too.
Expect to produce, at minimum, three years of the target's business tax returns and financial statements, a year-to-date profit and loss statement, and a clear picture of the seller's add-backs, the personal or one-time expenses run through the business that inflate its true owner earnings. For SBA deals above a certain size, the lender will order an independent business valuation from a qualified third party, and for larger acquisitions a quality of earnings analysis digs into whether the reported profits are real and repeatable.
Assembling this package early is the single biggest thing you can do to keep a deal on schedule. Our business loan documents checklist covers what to gather, and because an acquisition loan is sized to the business's earnings, it is worth understanding the mechanics of how much a business can borrow before you agree on a price.
The DSCR Lens: What a Lender Actually Sees
Underwriters reduce every acquisition to one question: after the sale, does the business throw off enough cash to cover the new loan payment with room to spare? The measure they use is the debt-service coverage ratio (DSCR), and most want to see roughly 1.15 to 1.25 or better. A DSCR of 1.25 means the business generates $1.25 of cash for every $1.00 of debt payment.
Here is a worked example. Suppose a business is priced at $1,000,000 and generates $150,000 in seller's discretionary earnings (SDE), the owner's total economic benefit. That is a multiple of about 6.7 times earnings, which is already on the high side for a small business.
Now run the debt. With a 10% equity injection, the buyer finances $900,000. At an assumed 11.5% over a 10-year term, the payment is about $12,650 a month, or roughly $151,800 a year. Look at what that means: the business earns $150,000, and the loan alone costs $151,800 a year, before the new owner pays themselves a single dollar. The DSCR is below 1.0. A lender declines this deal as structured.
What would make it work? Say the buyer needs a $60,000 salary and the lender wants a 1.25 cushion. The $150,000 in earnings, minus the $60,000 salary, leaves $90,000 to service debt. Divided by 1.25, that supports about $72,000 of annual debt service, roughly $6,000 a month, which at the same rate and term services a loan of about $425,000. With 10% down, that points to a purchase price closer to $470,000, not $1,000,000. This is precisely why sellers carry standby notes and why price negotiations matter: the cash flow, not the asking price, sets the ceiling on what can be financed.
Timeline and Common Deal-Killers
An SBA acquisition typically takes 60 to 90 days from accepted offer to closing, sometimes longer when a business valuation and real estate are involved. Conventional deals can move faster, but any acquisition requires enough time for real due diligence. Rushing it is how buyers overpay.
Certain issues will slow or sink financing no matter how attractive the headline numbers look. Watch for these before you fall in love with a business:
- Customer concentration. If one client accounts for 30% or more of revenue, losing them after the sale could sink the business, and lenders know it.
- Owner dependence. If the business runs entirely on the seller's personal relationships, expertise, or reputation, its earnings may not survive the transition. Lenders scrutinize how transferable the business really is.
- Declining revenue. Three years of falling sales undercuts the whole premise that you are buying proven, repeatable cash flow.
- Messy books. If the financials cannot be reconciled to tax returns and bank statements, an underwriter cannot verify the earnings, and the deal stalls.
None of these is automatically fatal, but each needs a credible answer. A concentration risk offset by a long contract, or owner dependence addressed by a transition period and a strong management team, can keep a good deal alive.

Frequently Asked Questions
How much money do I need to buy a business?
For an SBA 7(a) acquisition, plan on an equity injection of around 10% of the total project cost, though the exact figure depends on the deal. Part of that can sometimes come from a seller note on full standby rather than all from your own cash. Conventional acquisition loans usually require a larger down payment.
Can I use an SBA loan to buy a business?
Yes. The SBA 7(a) is the most common way small businesses are bought and sold, funding purchases up to $5 million. The business's own cash flow services the loan, and terms run up to 10 years for a business without real estate. The catch is time and paperwork: expect 60 to 90 days and a thorough due-diligence process.
What is SDE and why does it matter?
Seller's discretionary earnings is the total financial benefit an owner receives from the business: net profit plus the owner's salary, benefits, and any one-time or personal expenses added back. It is the number both valuation multiples and loan sizing are built on, because it reflects what the business actually produces for whoever runs it. A price expressed as a multiple of SDE is the quickest way to gauge whether a deal is reasonable.
Will the seller help finance the sale?
Often, yes. Seller financing of 10% to 30% is common, and many sellers welcome it because it can raise their total price and signals confidence in the business. On SBA deals, a seller note placed on full standby can even help satisfy the buyer's equity requirement, which is why these structures are so common in small-business acquisitions.
