How much money do I need to put down to buy a business?

Under current SBA rules the minimum equity injection for a complete change of ownership is roughly 10 percent of total project cost, and part of that can sometimes be satisfied by a seller note on qualifying standby terms. Conventional lenders typically expect more equity. The practical budget should also include working capital and closing costs beyond the injection itself.

Can I use the business I am buying as collateral?

Yes — that is how most acquisition debt works. Senior lenders take a lien on the acquired business’s assets, and asset-heavy targets can fund part of their own purchase through asset-based facilities against receivables, inventory, and equipment. The buyer’s personal guarantee is still standard below institutional deal sizes.

What is a seller note and why does every lender ask about it?

A seller note is financing provided by the seller — part of the price paid over time, subordinate to the senior debt. Lenders like it because it bridges valuation gaps, reduces senior leverage, and keeps the seller invested in a successful transition. Typical notes run several years, with terms negotiated alongside the senior facility.

How long does acquisition financing take?

SBA acquisition loans commonly run 45 to 90 days from complete file to closing, with quality-of-earnings and landlord or license issues the usual sources of delay. Structured conventional deals can move faster when the target’s records are clean. Building the financing timeline into the purchase agreement — rather than promising a close the process cannot meet — is basic deal hygiene.

Can I finance an acquisition if my own company is the buyer?

Yes. Add-on acquisitions are underwritten on the combined entity: your financials plus the target’s, the synergies you can document, and the combined balance sheet. Existing operators often have better structures available than individual buyers — including asset-based facilities across both companies’ working capital.

What multiple of earnings can be financed?

There is no fixed multiple; lenders size debt to coverage, not price. The question underwriting asks is whether historical cash flow covers the proposed payments with margin — typically requiring coverage comfortably above break-even after a market-rate manager’s salary. A price the market supports can still be a structure the cash flow cannot; the stack has to reconcile the two.

Capital solution

Acquisition financing: buying a business is a capital stack, not a loan.

Almost no acquisition is funded by one check. Real deals layer buyer equity, senior debt, seller financing, and sometimes the target’s own assets — and the structure decides whether the deal closes and whether it breathes afterward.

Reviewed by Ryan Hurley, Co-Founder & CEO

Acquisition financing combines several layers: buyer equity (commonly around 10 percent of project cost at minimum under SBA rules, more in conventional deals), senior debt sized to the target’s cash flow, and frequently a seller note bridging the gap. SBA 7(a) is the dominant structure for acquisitions up to $5 million; larger and asset-heavy deals draw on conventional cash-flow lending and asset-based facilities against the target’s receivables, inventory, and equipment.

Good fit

Cash-flowing targets, real records

A business with demonstrable earnings, clean books, and a seller willing to support an orderly transition — the raw material every structure needs.

Tradeoff

The debt outlives the honeymoon

Whatever structure closes the deal must still be payable in the slow quarter two years in. Overleveraged closings are how good acquisitions become distressed ones.

Review

Structure before price

The same purchase price can be a comfortable deal or an impossible one depending on how the layers stack. Negotiate the structure with as much care as the number.

The stack

The five layers of a real acquisition, and what each one costs.

Buyer equity. Every structure requires skin in the game. SBA rules currently require an injection of roughly 10 percent of total project cost; conventional lenders often expect more. Part of the injection can sometimes take the form of a seller note on standby terms — a structuring detail that changes how much cash a buyer actually needs.
Senior debt. The largest layer, sized to the target’s debt service coverage — its historical cash flow against the proposed payment. SBA 7(a) dominates below $5 million for its ten-year amortization; conventional cash-flow loans and bank facilities take over above it, typically at shorter terms and tighter covenants.
Seller financing. A note from the seller for part of the price, subordinate to the senior debt. Beyond bridging valuation gaps, it keeps the seller economically invested in a clean transition — which is exactly why lenders like seeing it. Typical notes run several years, and their terms (standby period, interest, subordination) are negotiated alongside the senior facility, not after it.
Asset-based layers. When the target carries receivables, inventory, or equipment, those assets can fund part of the purchase through an asset-based facility or equipment structure — reducing how much cash-flow debt the earnings must carry. Asset-heavy deals (distribution, manufacturing) often finance better through their balance sheets than their income statements.
Working capital at close. The layer first-time buyers forget. The business needs operating cash from day one — payroll clears before receivables do — and the acquisition budget should include a working-capital facility, not just the purchase price. Deals that close with empty accounts create their own crisis within a quarter.

The two dominant routes

SBA 7(a) below $5M; structured conventional above it.

The SBA route is how the majority of small-business acquisitions in this country actually close: up to $5 million, ten-year amortization, capped pricing, and tolerance for the collateral-light reality of buying a services business. The costs are process — a document-intensive file measured in weeks — and the program’s technical eligibility rules on equity injection, citizenship, and use of funds. The SBA loans page covers the mechanics and the disqualifiers in detail.

The structured route takes over when the deal exceeds SBA limits, the buyer is a company rather than an individual, or speed rules SBA out. Here the stack is assembled deal by deal: a conventional cash-flow loan or non-bank term facility as senior debt, asset-based borrowing against the target’s balance sheet, a seller note, and occasionally bridge capital to hit a closing date with permanent financing arranged behind it. Add-on acquisitions by existing operators — buying a competitor, a book of business, or a second location — usually live on this route, financed against the combined entity.

Before the LOI locks the structure

Have the stack designed while the terms are still negotiable.

The moment of maximum leverage is before the letter of intent is signed — seller note terms, what conveys, and working capital targets are all still open. A conversation at that stage shapes a financeable deal; a conversation after signing can only decorate one.

Declines

What actually kills acquisition deals in underwriting.

Cash flow that will not cover the debt. The first and final test: the target’s demonstrated earnings against the full proposed debt service, with a margin for the transition year. Add-backs help only when they are documented and defensible.
Unverifiable financials. Cash businesses with informal books, or sellers whose tax returns and claimed earnings disagree, force lenders to underwrite the smaller number — or walk.
Equity injection that cannot be sourced. Injection funds must be traceable and seasoned; last-minute borrowed injections unwind approvals late in the process.
Customer concentration in the target. A target whose revenue depends on two customers is a receivable, not a business, until the structure accounts for that risk — price adjustments, earnouts, or heavier seller paper.
Owner dependence. If the seller is the business — the relationships, the license, the craft — lenders will want transition terms, and buyers should want them more.
A stack with no working capital. Deals engineered to the last dollar of purchase price, with nothing behind them for operations, fail underwriting at good lenders and fail in reality at the rest.

Documentation

What the file requires, buyer and target both.

The LOI or purchase agreement, including price, terms, and what conveys.

A quality-of-earnings review or at minimum a defensible add-back schedule on larger deals.
Buyer personal financial statement, resume relevant to the business, and sourced injection funds.
Target A/R and A/P agings, inventory and equipment lists — the raw material for any asset-based layer.
Proposed seller-note terms, standby provisions, and transition plan.
