Watch: What If the Buyer Stops Paying Your Seller Note?

7 min

You agreed to a $300,000 seller note with 60 monthly payments. The first six payments came like clockwork. Then payment seven was five days late. Payment eight arrived two weeks late. Payment nine didn't come at all. The buyer called to say cash flow was tight — "just a temporary thing, we'll catch up next month." Payment ten was partial. Payment eleven was nothing.

You're now three months behind, $15,000 short, and staring at a question you should have answered before closing — the same question Austin business owners in this exact situation face every month: what do you do when the buyer stops paying?

More importantly — what should you have built into the note agreement that protects you right now?

Seller financing is common in small business transactions. Roughly 60–70% of deals in the Austin market involve some form of seller-carried note. The reasons are practical: SBA loans don't always cover the full purchase price, buyers want to reduce their cash outlay at closing, and sellers who carry a note often get a higher total sale price because they're expanding the pool of buyers who can afford the deal. But the note that protects you when things go right looks very different from the note that protects you when things go wrong.

## The Standard Seller Note — And Its Weaknesses

Most seller notes in small business transactions follow a simple template: fixed amount, fixed interest rate, fixed monthly payments over 3–7 years, subordinate to the SBA loan. That structure covers the basics. What it doesn't cover is what happens when the buyer's checks stop clearing.

A basic promissory note says the buyer owes you money and will pay it on a schedule. That's a contractual obligation — legally enforceable. But enforcement and collection are two different things. A promissory note without the right protections gives you the right to sue for breach of contract. It doesn't give you the ability to recover your money efficiently.

The protections that matter — the ones that distinguish a well-structured note from a standard template — are negotiated before closing. After the buyer defaults, your options are limited to whatever you built into the agreement.

## The Protections That Should Be in Every Seller Note

**Personal guarantee.** If the buyer is an LLC or corporation — which they almost always are — the business entity is the borrower. If the entity can't pay, your claim is against the entity's assets, not the buyer's personal assets. A personal guarantee from the individual buyer (or buyers) means that if the business fails to pay, you can pursue the individuals personally — their savings, their real estate, their other assets. Without a personal guarantee, a buyer who drives the business into the ground can walk away from the entity and leave you with a claim against an empty shell.

**Security interest in business assets.** Your note should be secured by a lien on the business assets — equipment, inventory, accounts receivable, intellectual property, customer lists, the operating business as a going concern. This security interest is perfected by filing a UCC-1 financing statement. If the buyer defaults, your security interest gives you priority over unsecured creditors in recovering the business assets.

The complication: if there's an SBA loan, the SBA lender's security interest is senior to yours. You're subordinate. In a default scenario, the SBA lender gets paid first from the business assets. What's left — if anything — is yours. This is the structural reality of subordinate seller notes, and it's why the other protections on this list matter even more.

**Acceleration clause.** If the buyer misses a payment (or misses multiple payments — the threshold is negotiable), the full remaining balance becomes due immediately. Without an acceleration clause, you can only pursue the missed payments one at a time. With one, a single default triggers the entire balance. This gives you leverage: the buyer who's behind $5,000 faces a very different conversation than the buyer who suddenly owes $280,000.

**Late payment penalties and default interest.** Standard late fees (5% of the overdue payment is typical) create an immediate cost for tardiness. Default interest — a higher rate that applies once the note is formally in default — increases the financial pressure on the buyer to cure the default quickly. A note at 6% interest that escalates to 12% on default changes the buyer's math.

**Cross-default provisions.** If the buyer defaults on any other obligation — the SBA loan, a lease, a vendor agreement — your note should also be considered in default. Why? Because a buyer who's defaulting on other obligations is likely headed for broader financial trouble. Cross-default lets you accelerate before the business's remaining value deteriorates further.

**Financial reporting covenants.** The right to receive quarterly (or monthly) financial statements from the business during the note period. This is an early warning system. If revenue is declining, expenses are rising, or cash reserves are depleting, you see it in the financials before you see it in a missed payment. Reporting covenants also prevent the buyer from stripping value from the business — paying themselves excessive salaries, taking distributions, or transferring assets — while your note is outstanding.

**Non-compete reinforcement.** Your purchase agreement probably includes a non-compete clause. Your seller note should reinforce it: if the buyer breaches the non-compete (by opening a competing business while still owing you money), the note accelerates. The non-compete and the note are connected — make the contract reflect that.

## When Default Happens: The Escalation Path

Despite protections, defaults happen. Here's the typical sequence.

**Notice and cure period.** Most well-drafted notes include a cure period — typically 10–30 days — after written notice of default. This gives the buyer a defined window to make the missed payment before you trigger acceleration. The cure period is important: it creates a clear record that you gave the buyer an opportunity to fix the problem, which strengthens your position if the dispute goes to litigation or arbitration.

**Demand letter.** If the cure period passes without payment, your attorney sends a formal demand. The demand cites the specific default, invokes the acceleration clause, and states the full amount now due. This is a legal instrument, not a negotiation. It creates the paper trail that supports enforcement.

**Negotiation or restructuring.** Before pursuing legal remedies, many sellers negotiate. The buyer may offer a modified payment schedule, a partial lump sum, or additional collateral. Whether to accept depends on your assessment of the buyer's ability and willingness to pay. A buyer who's having a temporary cash flow problem and communicates proactively is a different situation than a buyer who's gone silent and is avoiding contact.

One option: deed in lieu of foreclosure (or its business equivalent). The buyer surrenders the business assets back to you in exchange for releasing the note obligation. You get the business back — which may or may not be worth what's owed. But it avoids the cost and delay of litigation.

**Legal enforcement.** If negotiation fails, you pursue legal remedies. This could include a lawsuit for breach of the promissory note, foreclosure on the security interest (seizing and selling the business assets), enforcement of the personal guarantee, or a combination. Litigation in Texas typically takes 6–18 months and costs $15,000–$50,000 or more in legal fees — depending on whether the buyer contests the action.

**Bankruptcy complication.** If the buyer files for bankruptcy protection, your enforcement options are frozen by the automatic stay. Secured creditors have priority over unsecured creditors in bankruptcy, but the SBA lender is ahead of you. In a bankruptcy scenario, seller note holders often recover pennies on the dollar. This is the worst-case outcome — and it's why prevention (through strong upfront protections) is worth far more than cure.

## The SBA Standby Agreement Problem

Here's a structural issue that many Austin business sellers don't fully understand until it's too late.

When an SBA loan is involved in the transaction, the SBA requires the seller note to be on "full standby" for a period — typically the first two years after closing. Full standby means no payments — neither principal nor interest — during that period. The logic: the SBA wants the business's cash flow dedicated to servicing the SBA loan, not split between the SBA and the seller.

After the standby period, payments begin. But you've just gone two years without any payment from the buyer while the business operated under someone else's management. If the business has deteriorated during those two years — lost customers, lost staff, accumulated debt — the buyer who starts making payments in year three may not be the same financial profile as the buyer who closed the deal.

The standby period creates a gap between when you sold the business and when you start receiving your seller-financed payments. That gap is risk. Mitigate it with financial reporting covenants that keep you informed during the standby period, and with protections that trigger if the business deteriorates below certain thresholds.

## How to Size the Seller Note

The less you finance, the less you risk. That's obvious. But the market dynamics in Austin small business transactions create pressure to carry meaningful seller notes — often 10–30% of the purchase price.

A framework: the seller note should represent an amount you can afford to lose. Not an amount you want to lose — an amount that doesn't destroy your financial plan if it doesn't get paid. If you're selling a business for $2 million and carrying a $200,000 note, the default risk is contained. If you're carrying a $600,000 note, default could materially alter your retirement, your next investment, your plans.

Structure the deal to maximize cash at closing. Negotiate for SBA financing that covers the highest possible percentage of the purchase price. Accept a smaller seller note with stronger protections rather than a larger note with weaker terms. And never — under any circumstances — accept a seller note without a personal guarantee.

## The Bottom Line

Seller financing makes deals happen. It expands the buyer pool, it supports higher sale prices, and it's a fixture of the Austin small business market. But a seller note is a loan. You're the lender. And lenders who don't protect themselves get burned.

Every protection on this list — personal guarantee, security interest, acceleration, financial reporting, cross-default — is negotiated before closing. After the buyer defaults, your options are limited to whatever you put in the contract. The sellers who built strong notes collect their money. The ones who signed standard templates hire lawyers.

Build the note for the scenario you hope never happens. Because by the time it does, the contract is all you've got.
