Introduction

In the world of mergers and acquisitions (M&A), creative deal structuring often drives success. One of the most practical and flexible financing tools available to both buyers and sellers is the seller note. When properly structured, seller notes can bridge valuation gaps, reduce the need for upfront cash, and align incentives—making them a powerful tool in many M&A transactions.

This guide breaks down how seller notes work, their benefits for both parties, and important legal considerations when using them.

What Are Seller Notes in M&A?

A seller note is a form of deferred payment used in M&A deals. Rather than paying the full purchase price at closing, the buyer issues a promissory note to the seller, agreeing to pay a portion of the purchase price over time, usually with interest.

In essence, it’s a legally binding agreement that may be secured by the business’s assets or stock. These notes can play a crucial role in getting deals done—especially in the lower middle market (typically smaller deals in the M&A space).

Key Advantages of Seller Notes For Buyers: Preserve Capital and Manage Risk

Seller notes allow buyers to:

• Reduce upfront capital requirements
• Preserve working capital for post-closing operations or growth
• Include offset provisions, allowing deferred payments to be reduced if certain seller obligations aren’t met

For Sellers: Increase Valuation and Ongoing Returns

Sellers benefit by:

• Potentially receiving a higher total purchase price
• Earning interest on deferred payments
• Remaining financially connected to the company’s performance

Typical Seller Note Terms

While seller notes are highly customizable, common terms include:

• Principal amount – The portion of the purchase price deferred
• Interest rate – Often benchmarked to rates like SOFR or Prime
• Payment schedule – Monthly, quarterly, or annual payments over 2–5 years
• Security – May be secured by business assets or equity
• Covenants – Contractual obligations to protect seller interests

Example: Basic Seller Note Structure

Purchase Price: $10 million

Cash at Closing: $7 million Seller Note: $3 million, repaid over 4 years at 6% interest

This structure gives the seller immediate liquidity and additional income from interest, while easing the buyer’s financial burden.

Why Seller Notes Are Common in Lower Middle Market M&A

In deals under $50 million—especially in founder-led, private equity, or management buyout transactions—seller notes are widely used. That’s because:

• Traditional bank financing may not be ideal or sufficient
• Buyers want flexibility without over-leveraging
• Sellers are often more flexible on deal structure to close a transaction

Key Legal Considerations in Structuring Seller Notes: Protecting the Seller’s Position

Sellers should ensure their notes are:

• Secured, either through collateral or personal guarantees
• Prioritized, meaning they rank above other unsecured creditors if the buyer defaults

Aligning Incentives

Seller notes can keep the seller involved post-closing—helping maintain relationships, assist with transition, and ensure business continuity. This alignment can benefit both parties.

Avoiding Common Pitfalls

• Overly aggressive terms may cause buyer default risk
• Lack of security exposes sellers to financial losses
• Weak covenants fail to protect sellers from major changes in the buyer’s operations

Why You Need an Experienced M&A Attorney

Because seller financing touches on both legal and financial strategy, experienced counsel is critical. A skilled M&A attorney can:

• Negotiate favorable repayment terms and interest rates
• Secure the seller’s interests with liens or UCC filings
• Draft robust covenants that strike the right balance between protection and flexibility
