Most first-time buyers think of business acquisition financing as a binary choice: SBA loan or cash. In reality, the capital structure of a small business acquisition can be assembled from several sources — and understanding all of them gives you more flexibility, more deal options, and often a stronger negotiating position with sellers.
The SBA 7(a) loan: the baseline
The SBA 7(a) loan program is the most widely used financing tool for small business acquisitions in the $300K–$5M range. It allows buyers to finance up to 90% of the purchase price with a government-guaranteed loan, typically at 10–25 year terms and competitive interest rates.
Key features of SBA 7(a) for acquisitions:
- Down payment: typically 10% of purchase price
- Maximum loan amount: $5M
- Term: typically 10 years for business acquisitions
- Rate: variable, tied to Prime rate plus a spread
- Personal guarantee required from all owners with 20%+ equity
- Full collateral pledge required when available
The SBA loan is powerful — but it comes with constraints. Not all businesses qualify. Lenders have their own overlays on top of SBA guidelines. And the process is slow, typically taking 60–90 days from application to funding.
Seller financing: the most flexible tool
Seller financing — where the seller accepts a promissory note for part of the purchase price rather than cash at close — is the second most common financing element in small business deals. It is also the most flexible, because the terms are negotiated directly between buyer and seller.
Typical seller note structure:
- Amount: 10–30% of purchase price
- Interest rate: 5–8% (negotiated)
- Term: 3–7 years
- Often subordinated to SBA loan (required by SBA lenders)
Seller financing does two things for buyers: it reduces the amount of cash needed at close, and it keeps the seller financially interested in the business's post-close performance — which can be a meaningful alignment incentive during the transition period.
SBA + seller note combination: When an SBA loan requires a 10% buyer down payment and the seller finances an additional 10–15%, the buyer's cash requirement at close can drop to as little as 0–5% of the purchase price in some deals. This is the most common capital stack for sub-$2M acquisitions.
Conventional bank financing
Conventional business acquisition loans — without the SBA guarantee — are available from community banks and regional lenders, typically for businesses with strong collateral and borrowers with established banking relationships. They are less common than SBA loans because they require larger down payments (20–30%) and shorter terms, but they have fewer restrictions and faster closing timelines.
Conventional financing makes sense when: the buyer has a strong existing relationship with a lender, the business has significant hard assets that serve as collateral, or the buyer wants to avoid SBA-specific restrictions on post-close distributions and management changes.
Rollover equity (ROBS)
A Rollover for Business Startups (ROBS) arrangement allows buyers to use funds from a 401(k) or other qualified retirement account to fund the down payment — without triggering early withdrawal penalties or taxes. The structure involves creating a C-corporation, setting up a new retirement plan that invests in the corporation's stock, and using those funds to acquire the business.
ROBS arrangements are legitimate but complex. They require ongoing compliance with IRS and Department of Labor regulations and must be set up and maintained correctly. Used by a meaningful percentage of small business buyers, particularly those who have accumulated significant retirement assets but limited liquid savings.
Equity partners and search funds
Some buyers bring in an equity partner — a private individual or small investment group — who provides capital in exchange for a minority ownership stake. This increases the total capital available at close and can reduce the debt burden, but it also means sharing ownership, profits, and control with another party.
Search funds are a more structured version of this model, where a searcher raises a defined pool of capital from investors before identifying an acquisition target. The investors fund the search and the acquisition in exchange for equity. Search fund acquisitions are common in the $2M–$10M EBITDA range but less typical for smaller deals.
Combining sources: the typical capital stack
| Source | Typical % of deal | Best for |
|---|---|---|
| SBA 7(a) loan | 70–80% | Most deals under $5M |
| Seller financing | 10–20% | Bridging valuation gaps, reducing cash at close |
| Buyer cash / equity | 10–20% | Required in all deals |
| Conventional bank loan | 50–70% | Asset-heavy businesses, experienced borrowers |
| Rollover equity (ROBS) | 10–30% | Buyers with retirement assets, limited liquid savings |
| Equity partner | Varies | Larger deals, buyers who want shared risk |
One thing every financing structure has in common: lenders and equity partners all want to see verified, independent financials before they commit. A quality of earnings report is not just a due diligence tool — it is often a requirement for SBA lenders, and a meaningful credibility signal for any other financing source.
