In most small business sales the seller lends part of the price back to the buyer. It closes the gap between what a bank will fund and what the seller wants, and it signals that the seller believes the business will keep performing. It also means the seller is still exposed years after handing over the keys, which is why the structure deserves more attention than it usually gets.
In short
- A seller note is not a payment plan. It is a loan, and it needs the terms a lender would insist on.
- The interest rate matters less than the security, the priority, and what happens on the first missed payment.
- Write the default remedies while everyone is friendly. That is the only time they get written fairly.
Why it exists at all
Bank lending against a small business is limited by what a lender can seize and sell, which for a service business is very little. That leaves a gap between the price and the funding, and seller financing usually fills it.
It does something else too. A seller who takes a note is staking part of their proceeds on the business continuing to perform, which buyers read as confidence. Sellers who refuse any deferred consideration often find buyers reading that as the opposite, fairly or not.
Model every payment, not just the headline
A price of $1,200,000 tells you almost nothing. What matters is the shape: how much lands at closing, how much is financed, over what term, at what rate, and whether a balloon payment arrives before the business can realistically fund it.
| Term | Structure A | Structure B |
|---|---|---|
| Headline price | $1,200,000 | $1,200,000 |
| Cash at closing | $900,000 | $600,000 |
| Seller note | $300,000 | $600,000 |
| Term | 5 years, fully amortizing | 3 years, interest only |
| Balloon | none | $600,000 at month 36 |
| Seller's real exposure | declining monthly | unchanged for three years |
Structure B carries the whole risk to a single date, and that date arrives whether or not the business is in a position to refinance. Sellers accept these more often than they should, because the headline number is identical.
Security, priority, and the words that matter
If a bank is also lending, it will almost certainly require the seller note to sit behind it, and it may restrict payments to the seller while its own loan is impaired. That subordination is normal, but a seller should understand precisely what it prevents before signing.
Beyond priority, the questions are what secures the note, who guarantees it, and what happens if payments stop. A personal guarantee from a buyer with no assets is decoration. Security over the business assets is only useful if you would genuinely want the business back.
- What secures the note: business assets, the shares or membership interests, or nothing
- Whether a personal guarantee exists, and whether it is worth anything
- Where the note sits relative to any bank debt, and what payments are blocked when
- Cure period before a missed payment becomes a default
- Whether default lets the seller take the business back, and in what condition
Offsets, and the argument you will actually have
The most common seller-note dispute is not a buyer who cannot pay. It is a buyer who claims something was misrepresented and stops paying while it is argued about. A well-drafted note says explicitly whether the buyer may withhold payments against a claim, and how such claims are resolved.
Sellers generally want the note paid regardless, with disputes handled separately. Buyers generally want the right to offset. Whichever way it lands, deciding it in the document is far cheaper than discovering the ambiguity eighteen months later.
Keep the model conditional until it is not
A structure sketched during negotiation is a proposal. It remains subject to diligence, to bank approval, to tax treatment that neither party may have modelled, and to legal documentation that will raise questions the outline did not.
Sellers in particular should take tax advice before agreeing to an instalment structure, because when tax falls due does not always follow when cash arrives, and finding that out afterwards is expensive.
Common questions
- How much of a small business sale is typically seller financed?
- Commonly somewhere between ten and fifty percent of the price, with the rest funded by buyer cash and bank debt. The proportion is driven by what a lender will advance, which depends heavily on whether the business has assets worth seizing. Service businesses with little equipment tend to need more seller financing than asset-heavy ones.
- What interest rate is normal on a seller note?
- Sellers usually seek something in the range of prevailing commercial lending rates, sometimes a little above, because they rank behind the bank and carry more risk. Rate is worth less argument than most parties give it: on a five-year note, a point of interest is worth far less than the difference between having security and not having it.
- What happens if the buyer stops paying?
- Whatever the note says, which is why it matters. Depending on the drafting, the seller may be able to accelerate the balance, enforce against the security, call on a guarantee, or in some structures take the business back — though a business returned after two years of poor management is rarely the business that was sold. If a bank sits ahead of the seller, its consent may be needed before any of this happens.
- Should the seller stay involved during the note period?
- Often a short, defined transition helps both sides, since the seller now has a direct financial interest in the business performing. It should be documented as a separate arrangement with a defined scope and end date. Open-ended involvement tends to blur who is actually running the business, which serves nobody when something goes wrong.
