Seller financing — where the seller accepts a promissory note for a portion of the purchase price, repaid from business cash flows over time — is present in approximately 77% of small business acquisitions, according to BizBuySell's 2024 transaction survey of over 8,200 closed deals. It is not a last resort. It is how small business M&A actually works, and understanding it before you enter negotiations is non-negotiable.
Why Sellers Offer Financing
Sellers who offer financing are not desperate. They are typically doing one of three things: expanding the buyer pool (most buyers cannot finance 100% of the purchase price through banks alone), demonstrating confidence in the business (a seller who puts up a note has skin in the game), or managing tax liability (installment sale treatment can defer capital gains recognition across multiple tax years under IRC Section 453).
The installment sale benefit is significant for sellers of businesses with low cost basis — which is most owner-operated businesses held for 10+ years. A seller who sold for $3M and has effectively zero basis might defer substantial capital gains taxes by spreading receipt of proceeds over 5–7 years. This is worth real money to them, and worth understanding as a buyer: it gives you negotiating leverage on rate and repayment terms.
Typical Seller Note Terms in ETA Deals
In the ETA and self-funded search universe, seller notes typically fall within these ranges: principal is 5–20% of the total purchase price, interest rate is 5–8% annually (amortized), term is 3–7 years, with a balloon payment at maturity common for longer terms. Full seller carry — where no institutional debt exists — is rare (approximately 8% of transactions per BizBuySell) and usually only occurs in very small deals or highly motivated sellers.
In SBA 7(a) transactions — the dominant financing structure for ETA deals — the SBA requires the seller note to be on full standby for the first 24 months when the down payment is below 10%. "Full standby" means no principal or interest payments during the standby period. This standby requirement protects the SBA's position as senior lender. After the standby period, seller note payments resume as scheduled.
Subordination and the Capital Stack
A seller note is always subordinate to senior debt (your SBA 7(a) loan or conventional bank debt). The intercreditor agreement — negotiated between your lender and the seller — governs what happens if the business defaults. Typically: senior lender gets paid first, seller gets paid second, equity holders (you) get paid last if anything remains. This is why lenders scrutinize the seller note terms: an aggressive seller note repayment schedule can starve the business of cash flow needed to service senior debt.
Lenders prefer seller notes that are deferred-interest or interest-only during the early operating years. If your lender pushes back on a seller note, ask them specifically what structure would satisfy their debt service coverage ratio requirements — usually 1.25x DSCR — and present that structure back to the seller. Most sellers will accept adjusted terms rather than lose the deal.
How to Negotiate the Seller Note
Use the seller note as a bridge to close valuation gaps. If the seller wants $5M and your DCF says $4.5M, a $500K seller note at 5% over 5 years costs you approximately $113K per year in debt service — a number you can model. Present it as: "We agree on operations and cash flow. Where we disagree is on the multiple. A seller note lets us share the upside if the business performs as you expect."
Also negotiate seller note forgiveness provisions tied to representations and warranties breaches. If the business loses a major customer that the seller knew was at risk but did not disclose, you want the right to offset that damage against seller note principal rather than pursuing costly litigation. Your attorney should draft this into the note purchase agreement as a setoff provision.
What Happens If You Cannot Pay the Seller Note
If the business underperforms and you cannot service both senior debt and the seller note, you will almost certainly breach the seller note first — senior lenders have much stronger enforcement rights and you need to protect that relationship. Many seller notes include cure periods (30–60 days before default is declared) and workout provisions. The best outcome is a restructured note; the worst is a judgment lien on business assets that complicates any future financing or sale.
This risk is why seller note due diligence goes both ways. You should be diligencing whether the business can support the total debt stack — senior debt plus seller note plus your management compensation — at a 1.25x DSCR minimum. If it cannot, renegotiate the purchase price, not just the structure.
