Seller Notes: Technical Mechanics of Vendor Financing in M&A

TL;DR: A Seller Note (also known as Vendor Financing) is a technical debt instrument where the seller of a business agrees to receive a portion of the purchase price over time instead of in cash at closing. Technically, it is a Subordinated Loan. The seller is effectively acting as a "Bank" for the buyer. In the capital stack, the Seller Note sits behind the Senior Bank Debt, meaning if the company goes bankrupt, the bank gets paid first and the seller gets paid last. This provides the buyer with "Gap Financing" and provides the bank with comfort that the seller still has "Skin in the Game."

🏛️ Technical Framework: The "Skin in the Game" Theory

Banks technically love Seller Notes for one reason: Seller Confidence.

• The Logic: If the seller is willing to wait 5 years for their money, they must believe the company is strong. If the seller demands 100% cash today, they might know something bad is about to happen.
• The Bank’s Mandate: A senior lender will often refuse to lend to a buyer unless the seller takes a note for at least 10% of the price. This forces the seller to cooperate during the transition (e.g., helping with customer introductions) because if the company fails, the seller loses their money.

⚙️ PIK (Paid-In-Kind) Interest: The "Snowball" Debt

Sophisticated M&A deals often use PIK Interest on the seller note.

1. The Mechanism: Instead of the company writing a check for interest every month, the interest is technically "Added to the Principal" of the loan.
2. The Math: If the note is $1M at 10% PIK, after Year 1 the debt is $1.1M. After Year 2, it is $1.21M.
3. The Benefit: This is technically great for the buyer because it keeps cash inside the business to fund growth. For the seller, it is a way to "Compound" their returns, provided the company survives long enough to pay the final "Snowball."

🛡️ Subordination and "Standstill" Agreements

The most technical legal document for a Seller Note is the Subordination Agreement.

• The Hierarchy: It technically states that the seller has no right to sue the company or seize assets unless the bank says it's okay.
• The Standstill: If the company misses a payment to the seller, the seller often has to "Standstill" (wait) for 90 to 180 days before they can take any legal action. This prevents the seller from "Tripping" the company into bankruptcy while the bank is still trying to save it.

🔍 Forensic Indicators of "Seller Note Fragility"

Investigators look for these signals where a seller note is technically a "Bad Bet" for the seller:

• "Interest-Only" with a Balloon: Finding that the company only pays interest for 5 years and then owes 100% of the principal in Year 6. If the company can't refinance, the seller gets nothing.
• Missing "Negative Covenants": Failing to prevent the buyer from taking more debt that sits in front of the seller. This is technically "Diluting" the seller’s security.
• Unsecured Status: Finding that the seller note has zero collateral. If the company is liquidated, the seller is technically a "General Unsecured Creditor"—the same as the paperclip supplier.

Frequently Asked Questions (FAQ)

Is it better than an Earn-out?

Yes, technically. An Earn-out is a "Maybe." A Seller Note is a "Definitely" (it is a legal debt). The only risk is the company's survival.

What is "Deep" Subordination?

It is a technical clause where the seller cannot receive any payments (even interest) if the bank’s loan is in default.

Can I sell my Seller Note?

Yes, but usually only at a Deep Discount. Because the note is subordinated and risky, a third-party buyer might only pay you 60 cents on the dollar for it.

Why do sellers agree to this?

To close the deal. If the buyer can only get $80M from the bank and they need $100M to buy your company, the $20M Seller Note is the only way the deal happens.
