How Do You Finance a Business Acquisition?

By First Capital FundingPublished September 1, 2026Last reviewed September 1, 2026

Acquisition financing is judged on two businesses at once: the one being purchased and the buyer's ability to run it. Understanding both halves early is what separates deals that close from deals that stall in diligence.

Short Answer

Most small-business acquisitions in the U.S. are financed through SBA 7(a) loans, frequently combined with a buyer equity injection and a seller note. Underwriting centers on the target's historical cash flow and whether it comfortably covers the new debt service, plus the buyer's industry experience, credit, and available capital. Asset-heavy acquisitions can add equipment or real estate financing to the stack. Expect 60 to 90 days and substantial documentation from both sides.

The typical capital stack

Senior acquisition debt — most often an SBA 7(a) loan for small-business purchases.
Buyer equity injection — cash the buyer contributes, which lenders treat as evidence of commitment.
Seller financing — a note held by the seller, sometimes on standby, which also keeps the seller invested in a clean transition.
Asset financing — separate equipment or commercial real estate financing where the deal includes significant hard assets.

The exact proportions are set by the lender's program rules and the deal's characteristics, not by preference. Ask early what equity injection and seller-note structure a given program expects, because that shapes what price you can actually transact at.

What underwriting focuses on

Historical cash flow of the target, normalized for owner compensation and one-time items.
Debt service coverage: whether that cash flow comfortably exceeds the new payment with room to spare.
Buyer experience in the industry or in a closely transferable role.
Buyer credit and personal financial position.
Customer concentration in the target — one dominant customer is a common deal-killer.
Transferability: licenses, leases, key employees, and whether the business depends on the departing owner.

Valuation and the gap that has to be bridged

Lenders finance against a supportable valuation, and for SBA transactions an independent business valuation is typically part of the process. When the agreed purchase price exceeds what the valuation supports, the difference has to come from buyer equity or seller financing — it does not come from the lender.

This is why price negotiation and financing structure cannot be sequenced separately. A price agreed without reference to financeability often has to be renegotiated later.

Preparing before you submit

Three years of the target's tax returns and financial statements, plus year-to-date figures.
A letter of intent or draft purchase agreement with the structure spelled out.
Your own tax returns, personal financial statement, and resume showing relevant experience.
A sources and uses schedule showing exactly where every dollar comes from and goes.
Lease assignment terms, licensing requirements, and a transition plan with the seller.

Timeline realism

Acquisition financing is a documentation process more than a decision. Deals slip when the target's records are incomplete, not usually because the buyer was declined.

Key Takeaways

SBA 7(a) is the most common route for small-business acquisitions.
Buyer equity injection and seller notes commonly sit alongside senior debt.
Underwriting centers on the target's normalized cash flow covering new debt service.
Independent valuation limits how much of the price can be financed.
Incomplete target records are the leading cause of delay.
