I got a phone call last week that made my stomach drop.

A client, let’s call her Sarah, was in the final stages of selling her business. She’d found a buyer, negotiated terms, and was days away from closing. Everything seemed to be going smoothly.

Then the buyer said they didn’t want to sign the promissory note.

Sarah called me, her voice a mix of excitement and uncertainty. “The buyer is ready to move forward with everything else. They just have some concerns about the promissory note. Should I just… skip it? I don’t want to lose this deal.”

My answer was immediate: Absolutely not.

What Is a Promissory Note, and Why Does It Matter?

Before I explain why this was such a terrible idea, let me back up and talk about what a promissory note actually is.

When you sell a business, the buyer doesn’t always hand you a check for the full purchase price on day one. Often, the deal is structured with:

  • A down payment (maybe 20-40% of the total price)
  • Seller financing for the remaining balance, paid over time (often 3-5 years)

This is actually pretty common. It helps buyers who can’t get full bank financing, and it can make the deal more tax-efficient for sellers.

But here’s the catch: if the buyer is going to pay you over time, you need a legal document that spells out exactly what they owe you and when they have to pay it.

That document is called a promissory note.

Think of it as an IOU, but with teeth. It’s a legally binding contract that includes:

  • The total amount owed
  • The payment schedule (monthly, quarterly, etc.)
  • The interest rate (if any)
  • What happens if they miss a payment
  • The consequences of default
  • Your rights to collect if they don’t pay

Without a promissory note, you have nothing. No legal recourse. No documentation that they owe you anything. Just a handshake and a hope.

Why This Buyer’s Request Was a Massive Red Flag

When Sarah told me the buyer didn’t want to sign the promissory note, every alarm bell in my head went off.

Think about it from a logical standpoint: if someone genuinely intends to pay you, why would they refuse to sign a document saying they’ll pay you?

Here are the only reasons I can think of:

They don’t actually plan to pay you.

If they’re already looking for ways to avoid legal obligation before the deal even closes, what do you think happens after they have control of your business?

They want wiggle room to walk away from payments.

Without a promissory note, if they decide six months in that they don’t feel like paying anymore, you have almost no legal standing.

They’re hiding something about their financial situation.

Maybe they know they can’t actually afford the payments, and they don’t want to be held accountable when they default.

They’re testing your boundaries.

Some buyers will push to see what they can get away with. If you cave on something this fundamental, they know you’ll cave on other things too.

None of these scenarios end with you getting paid.

What Actually Happens When You Sell Without a Promissory Note

Let me paint you a picture of how this plays out.

You close the deal without the promissory note because you don’t want to “lose the buyer.” You get your down payment, let’s say it’s $150,000 on a $500,000 sale. You hand over your business, your customer list, your systems, everything.

The buyer now owns your business. You’re no longer in control.

Month one: the payment comes through. You breathe a sigh of relief. See? Everything’s fine.

Month two: the payment is a week late, but it arrives. They apologize, “just some cash flow issues getting started.”

Month three: no payment. You call. They’re evasive. “Things are tight this month. We’ll catch up next month.”

Month four: still nothing. Now you’re worried. You call your lawyer.

And here’s where it gets ugly: without a promissory note, you have almost no legal leverage.

You can’t prove the terms of the agreement, and you can’t demonstrate default. You can’t foreclose on the business or reclaim assets. You’re basically stuck hoping the buyer decides to do the right thing.

Meanwhile, they’re running your business, maybe running it into the ground, and you’re watching the remaining $350,000 you’re owed disappear.

This isn’t a hypothetical. I’ve seen variations of this scenario play out multiple times, and it’s heartbreaking every single time.

The Conversation I Had With Sarah

When Sarah asked if she should skip the promissory note, here’s what I told her:

“Sarah, you’ve built this business for fifteen years. You’ve poured your time, your energy, your money into making it successful. You’re entitled to the full purchase price you negotiated, not just a fraction.

If this buyer won’t sign a promissory note, they’re telling you they don’t plan to honor their commitment. And if they won’t put it in writing now, when they’re trying to win you over, what do you think happens later when they have all the power, and you have none?

Walk away from this buyer. A deal that doesn’t protect you isn’t a deal worth making.”

She was quiet for a moment. “But what if I can’t find another buyer?”

“Then you keep running your profitable business until you do. That’s a much better outcome than handing over your company to someone who’s already showing you they can’t be trusted.”

What Happened Next

To Sarah’s credit, she listened. She went back to the buyer and said the promissory note was non-negotiable.

The buyer pushed back. They made excuses. They tried to negotiate around it.

And then they walked away from the deal.

Was Sarah disappointed? Of course. She’d spent months on this sale, and now she was back to square one.

But here’s the thing: six weeks later, she found a different buyer. One who didn’t blink at signing a promissory note. One who had their financing lined up and was transparent about the whole process.

She closed that deal two months ago with a proper promissory note, and she’s already received three on-time payments.

That’s what the right buyer looks like.

Red Flags When Selling Your Business

Sarah’s situation isn’t unique. Business sales are complicated, emotional, and high-stakes, and that makes sellers vulnerable to bad deals.

Here are some red flags that should make you pump the brakes.

The buyer resists standard legal documentation.

Promissory notes, non-compete agreements, and asset purchase agreements are all normal. If they’re fighting you on basic protections, run.

They’re vague about financing.

A serious buyer has their financing figured out before they make an offer. If they’re hand-waving about “working it out later,” they’re not ready.

They want to renegotiate major terms at the last minute.

Some negotiation is normal, but drastically changing the deal right before closing is a manipulation tactic.

They pressure you to move quickly.

“We need to close this week, or the deal is off.” Real buyers don’t do this. Scammers do.

They ask you to stay on without clear terms.

Some buyer involvement during transition is normal, but if they’re expecting you to keep running the business indefinitely without compensation, that’s a problem.

Their story keeps changing.

Today, they’re buying it as an investment. Tomorrow it’s for their son. Next week, it’s part of a larger portfolio. Inconsistency = unreliability.

They won’t provide references or financial statements.

 You’re trusting them with your life’s work. You have every right to vet them thoroughly.

What Should Be in Your Promissory Note

If you’re selling your business with seller financing, your promissory note should include:

The principal amount – Total amount owed to you

Payment schedule – How much, how often (monthly, quarterly, etc.)

Interest rate – Yes, you should charge interest on seller financing

Payment due dates – Specific dates, not “around the 15th”

Late payment penalties – Consequences for missed payments

Default terms – What constitutes default, and what happens when it occurs

Security interest – Ideally, you retain some security interest in the business assets until paid in full

Personal guarantee – If possible, the buyer personally guarantees the debt, not just their business entity

Acceleration clause – If they default, the entire remaining balance becomes due immediately

Your rights to collect – Legal remedies available if they don’t pay

This isn’t optional. This is the bare minimum to protect yourself.

Other Critical Documents in a Business Sale

While we’re on the topic, a promissory note isn’t the only document you need. A proper business sale should include:

Asset Purchase Agreement or Stock Purchase Agreement – The main contract outlining what’s being sold and for how much

Bill of Sale – Transfers ownership of physical assets

Non-Compete Agreement – Prevents you from starting a competing business (and vice versa)

Non-Disclosure Agreement – Protects confidential business information

Employment/Consulting Agreement – If you’re staying on during transition, this defines your role and compensation

Lease Assignment – If you’re transferring a lease on property or equipment

Customer/Vendor Notifications – Formal communications about the ownership change

A good business attorney will make sure all of these are in place. If your buyer is resisting any of them, that’s a warning sign.

The Bottom Line

Selling your business is probably the biggest financial transaction of your life. You’ve spent years, maybe decades, building something valuable.

Don’t throw away your leverage at the finish line.

If a buyer won’t sign a promissory note (or any other standard legal document), they’re showing you exactly who they are: someone who doesn’t plan to honor their commitments.

Believe them.

Walk away. Find a better buyer. Protect yourself.

Because here’s the truth: a bad deal is worse than no deal.

No deal means you still own your business. You’re still in control. You can keep running it, growing it, and looking for the right buyer.

A bad deal means you’ve handed over everything you built to someone who’s going to stop paying you, and you’ll spend the next few years in legal battles trying to get back a fraction of what you’re owed.

I’ve seen both scenarios. The first one is frustrating. The second one is devastating.

Don’t let excitement about finally selling cloud your judgment about basic protections. The right buyer will respect your need for security. The wrong buyer will fight you on it.

And if you’re ever unsure whether something is reasonable or whether you should give in on a particular point? Call someone who understands business sales and can give you objective advice.

That’s what saved Sarah from making a $350,000 mistake.
