Popular Business Acquisition Loans: How to Finance a Company Purchase

The most popular business acquisition loans are the SBA 7(a) loan, seller financing (a seller note), conventional bank acquisition loans, and revenue-based financing — and most closed deals use a combination of two or more rather than a single source. The SBA 7(a) dominates because it funds up to $5 million with as little as 10% buyer equity; seller notes bridge the gap and keep the previous owner invested in the handoff; conventional term loans suit buyers with strong collateral and credit; and revenue-based financing covers the working-capital shortfall that a purchase price rarely includes. Which one leads your deal comes down to the target company's cash flow, your down payment, your credit profile, and how fast you need to close.

The four popular acquisition loan types, at a glance

Buyers rarely finance an acquisition with a single instrument. Underwriters expect a capital stack — a blend of sources that together cover the purchase price plus the cash the business needs to keep running after the wire clears. Here is how the four most-used tools actually behave in a deal.

• SBA 7(a) acquisition loan — The default path for most Main Street purchases under $5M. Terms up to 10 years for a business (25 years if real estate is included), buyer injection commonly around 10%, and a government guaranty that lets banks say yes to goodwill-heavy deals they'd otherwise decline. Slowest to close (45-90 days) and paperwork-heavy.
• Seller financing (seller note) — The seller carries a portion of the price, typically 10-30%, paid back from the business's future cash flow. Cheap, flexible, and a strong signal the seller believes in the numbers. Often required by SBA lenders to be on full standby for the first years.
• Conventional bank acquisition loan — A straight commercial term loan, no SBA guaranty. Best rates and terms, but the bank wants hard collateral, seasoned buyer experience, and clean cash flow. Higher equity requirement, often 20-30%.
• Revenue-based financing / MCA marketplace — Not for the purchase price itself, but for the working capital, inventory buy, payroll bridge, and transition costs that hit right after close. Approval leans on the business's bank deposits and revenue rather than the buyer's credit, funds in 24-48 hours, and starts around $10,000. This is the fast layer that keeps a newly acquired business liquid while the slower loans season.

How lenders underwrite an acquisition (what they actually check)

Buying a business is underwritten differently from a startup or an equipment loan, because the lender is betting on cash flow that already exists. Three numbers drive almost every approval:

1. Debt Service Coverage Ratio (DSCR). Lenders want the acquired business's cash flow to cover the new loan payments with room to spare — most look for a DSCR of roughly 1.25x or better. If the business's adjusted cash flow doesn't comfortably clear the projected payments, the deal stalls no matter how good your credit is.
2. Buyer equity injection. You have skin in the game. SBA deals typically need about 10% down (a portion of which can be a standby seller note); conventional deals want more. Sourcing that injection — and proving it isn't borrowed on terms that create hidden debt — is a common closing snag.
3. Buyer experience and credit. Relevant industry or management experience de-risks the transition in the lender's eyes. Personal credit still matters, but on an acquisition the business's track record can carry a thinner personal profile than a startup ever could.

Beyond the numbers, expect a business valuation, a review of three years of tax returns and financials, a purchase agreement, and — for SBA — a personal guaranty from anyone owning 20% or more. The single most common delay is quality-of-earnings questions: sellers who run personal expenses through the business make cash flow look lower than it is, and every add-back has to be documented.

Decision framework: which acquisition loan fits your deal

Match the financing to the deal, not the other way around. Here is the plain logic underwriters use.

SBA 7(a) works best when

• The purchase price is between roughly $350K and $5M and the business has clean, verifiable cash flow.
• You have around 10% to inject and can wait 45-90 days to close.
• The deal is goodwill-heavy (few hard assets), which conventional banks dislike.

Avoid SBA when you need to close in weeks, the seller won't cooperate with document requests, or the business's tax returns don't support the asking price.

Seller financing works best when

• There's a valuation gap between what the seller wants and what a bank will lend.
• You want the seller economically motivated to make the transition succeed.
• You're combining it with an SBA loan to reduce your out-of-pocket injection.

Avoid relying only on seller financing when the seller wants most of the price in cash at close, or the note terms would strain post-close cash flow.

Conventional bank loan works best when

• You have strong personal credit, real collateral, and 20-30% down.
• The business has hard assets (equipment, real estate, receivables) to secure the loan.
• You want the lowest available rate and can meet stricter terms.

Avoid conventional financing when the deal is mostly goodwill or your down payment is thin.

Revenue-based / MCA marketplace financing works best when

• You need working capital fast — post-close payroll, inventory, a supplier deposit, or a bridge while an SBA loan finalizes.
• Approval needs to rest on the business's bank deposits and revenue rather than a perfect credit score (FICO 500+ can qualify), and you need at least about $10,000.
• Speed matters more than the lowest possible cost of capital — funding in 24-48 hours.

Avoid revenue-based financing when you're trying to fund the entire purchase price with it (it's built for working capital and bridges, not seven-figure buyouts) or when cash flow is already too thin to absorb a daily or weekly remittance. It is a working-capital layer, never a promise — nothing here is guaranteed, and approval always depends on your deposits.

Example capital stacks for a $600,000 acquisition

These are illustrative structures, not quotes. Real terms depend on the business, the buyer, and the lender. All figures below are for example only.

Notice the pattern: the slow, cheap money (SBA, conventional) funds the purchase price, while the fast, flexible money (revenue-based) funds the liquidity gap the day after closing. Underwriters like buyers who plan the working-capital layer before close, not after they realize the acquired business's checking account transferred nearly empty.

The working-capital gap nobody warns buyers about

Here's what surprises most first-time buyers: the purchase price and the cash to run the business are two different problems. Many deals transfer the business's assets but not its cash — the seller keeps the bank balance. On day one you own payroll, rent, supplier invoices, and receivables that won't collect for 30-60 days, with an empty operating account.

Acquisition loans are sized to the purchase price, not to that post-close cash burn. This is where revenue-based financing earns its place in the stack. Because it underwrites on the business's own deposit history and revenue rather than the buyer's credit alone, a marketplace can often approve a working-capital advance quickly once the business is under your ownership and depositing. Minimums start around $10,000, FICO 500+ can qualify, and funding commonly lands in 24-48 hours — fast enough to make a first payroll or a supplier deposit that keeps the doors open.

The underwriter's advice: build a 90-day post-close cash-flow projection before you sign, and line up your working-capital source in parallel with your acquisition loan. Do not wait until the account is empty to start an application.

How to strengthen your acquisition loan application

• Get a quality-of-earnings review. Even a light one. Documented add-backs (owner salary, personal expenses, one-time costs) can materially raise the cash flow a lender will credit, which raises the price you can finance.
• Negotiate a seller note early. A seller willing to carry 10-20% on standby often unlocks the whole SBA structure and lowers your injection.
• Source your down payment cleanly. Lenders trace injection funds. Gifts, retirement rollovers, and home equity each have rules — document them in advance.
• Show relevant experience. A short transition plan and evidence you can run the business reduces perceived risk more than most buyers expect.
• Plan the working-capital layer. Bring a projection showing you've accounted for post-close liquidity. It signals operator-level thinking and prevents the cash crunch that sinks otherwise good acquisitions.
