Seller Financing: What It Is, How It Works, and Why It Changes Your Deal
Seller financing is when the seller of a business accepts installment payments rather than full cash at closing — effectively acting as the bank for part of the purchase price. Instead of receiving everything upfront, the seller takes a promissory note from the buyer and collects principal and interest over a defined period.
It is the single most common deal mechanism in small business acquisitions. The large majority of transactions under $5M include at least some seller financing.
How Seller Financing Works
The seller and buyer agree on a portion of the purchase price that the seller will "carry" — meaning the seller doesn't receive that amount at closing. The buyer signs a promissory note committing to repay it over time, typically with interest. The note is secured by a lien on business assets (and often a personal guarantee from the buyer).
Typical terms:
- Amount: 10% to 60% of the purchase price (motivated sellers sometimes carry more)
- Interest rate: 5% to 8% annually
- Term: 3 to 7 years
- Amortization: monthly payments of principal and interest, sometimes with a balloon payment
- Security: first or second lien on business assets; personal guarantee
- Standby: if an SBA loan is involved, the seller note must be on full standby for 24 months
Why Sellers Offer It
Sellers accept installments for three concrete reasons. First, seller financing lets them command a higher purchase price — buyers pay a premium for the ability to close with less cash. Second, an installment sale can spread the seller's taxable gain across multiple years, potentially reducing the tax hit depending on their situation (consult a CPA). Third, carrying a note signals confidence in the business to buyers, which actually helps close deals.
A seller who flatly refuses any financing is worth scrutinizing — it can mean they need immediate liquidity for a specific reason, or that they don't believe the business will perform well enough to support the payments.
Why Buyers Want It
For buyers, seller financing reduces the cash required at closing and is usually cheaper and faster to arrange than third-party debt. More importantly, it aligns the seller's interest with the buyer's success: a seller who is owed $200K over 5 years has a strong incentive to cooperate during the transition, provide good introductions, and not compete against the buyer.
Example: A $600K Acquisition With Seller Financing
Purchase price: $600,000
Down payment: $120,000 (20%)
SBA loan: $330,000
Seller note: $150,000 at 6.5% over 5 years
The seller note generates a monthly payment of approximately $2,933. Buyers model these payments against expected cash flow in the AcquireCalc deal calculator to confirm the business can service all the debt comfortably — the standard threshold is a DSCR of 1.25× or above.
SBA and Seller Financing
If the acquisition is financed with an SBA 7(a) loan, the SBA imposes specific rules on seller notes. Seller financing that counts toward the buyer's equity injection must be on full standby for 24 months after closing — meaning no principal or interest payments from the business during that window. This is non-negotiable; lenders will not fund around it. Some sellers accept partial standby (interest-only for 24 months) depending on lender requirements.
