Earnout vs. Seller Note:Two Very Different Ways to Defer Purchase Price

Both mechanisms mean the seller does not get all the money at closing. The difference - one is debt, the other is contingent - is the most important distinction in any LOI negotiation over deferred consideration.

Key Takeaways

  • Seller note: Unconditional debt. Buyer owes the seller a fixed payment regardless of performance. Predictable for sellers.
  • Earnout: Contingent on future performance. Seller can receive zero if the business misses targets. Unpredictable - and often disputed.
  • Sellers should always negotiate to convert as much deferred consideration as possible from earnout to seller note format.
  • Seller notes can be combined with earnouts in the same deal - unconditional note for one portion, performance contingent earnout for another.
  • Seller notes are subject to personal guarantee and security negotiation. Unsecured seller notes behind senior bank debt are at real risk if the business struggles post-closing.

When a buyer cannot or will not pay the full purchase price at closing, the parties have two primary tools for deferring consideration: the seller note and the earnout. These look similar on a deal summary - both represent money the seller will receive in the future. But they are structurally very different instruments with very different risk profiles.

The seller note is debt. The buyer owes it. The seller has a legal claim as a creditor. The earnout is conditional - the seller collects only if the business hits targets that the buyer now controls. The difference between having a promissory note for $500K and having an earnout for $500K is the difference between a contractual right to be paid and a hope that the business performs.

Protecting Your Seller Note: Key Terms to Negotiate

What sellers should push for

  • Security interest in business assets (first lien if no bank debt, subordinated to bank if bank debt exists)
  • Personal guarantee from the buyer or principal individuals
  • Quarterly financial reporting so seller can monitor the business
  • Acceleration clause if buyer misses payment, breaches financial covenants, or sells the business again
  • No right of offset - buyer cannot reduce note payments because of indemnification claims or earnout shortfalls

What buyers push back with

  • Unsecured note (no security interest)
  • Deep subordination to bank debt with payment blocks during covenant events
  • Right of offset against indemnification claims
  • No reporting requirements or covenants
  • Long maturity with bullet payment (all due at end)

Seller note terms in your purchase agreement need review. Security, subordination, and offset rights are the provisions that determine real recoverability. Request a consultation →

Frequently Asked Questions

What is the difference between an earnout and a seller note?

A seller note (also called a seller promissory note or seller financing) is unconditional debt - the buyer borrows a portion of the purchase price from the seller and repays it with interest over a defined period, regardless of how the business performs. An earnout is contingent deferred consideration - the seller receives additional payment only if the acquired business meets specific financial targets after closing. The key distinction is certainty: a seller note gives the seller a contractual right to a defined payment schedule. An earnout gives the seller a right to additional consideration that depends on future results the seller no longer controls. For sellers, a seller note is almost always preferable to an earnout of the same amount.

Why would a seller accept an earnout instead of a seller note?

Sellers accept earnouts when: (1) the buyer will not agree to a seller note of the necessary size - often because the buyer's total debt capacity is constrained; (2) the deal has a genuine valuation gap that neither party can bridge with a fixed price - the earnout is the compromise; (3) the seller believes strongly in the business's future performance and is willing to bet on it; or (4) the buyer specifically requires the seller to have 'skin in the game' to ensure continued post-closing engagement. Sellers should be aware that earnouts are consistently the most disputed element of purchase price - a seller note is almost always more reliable and should be negotiated for whenever possible.

How is a seller note typically structured?

A seller note is typically a 3-7 year promissory note with an interest rate of 5-8% (interest rates have risen in recent years - prevailing AFR-based rates apply for tax purposes). Principal can be paid in equal installments, bullet (all at maturity), or based on a specific amortization schedule. The note is typically unsecured but subordinated to any senior bank debt. Buyers often seek 'subordination agreements' from the seller, acknowledging that the bank lender's claims are senior. Key terms to negotiate: interest rate, amortization schedule, prepayment rights (can the buyer pay early?), events of default, and security (if any - some seller notes are secured by the business's assets or by a personal guarantee from the buyer).

Can you have both an earnout and a seller note in the same deal?

Yes, and this combination is common in smaller middle-market deals. The deal structure might be: 60% cash at closing, 20% seller note (unconditional, pays over 5 years), 20% earnout (contingent on 2-year performance). The seller note gives the seller a reliable payment stream; the earnout gives the buyer a mechanism to defer the highest-risk portion of the price until the business's trajectory is clearer. Sellers in this structure should ensure that the seller note and earnout payments do not interfere with each other - specifically, that the buyer cannot withhold seller note payments as an offset against claimed earnout shortfalls.

What happens to the seller note if the business fails after closing?

If the business fails, the seller note is at serious risk. Seller notes are typically unsecured (or at best subordinated to senior bank debt), so in an insolvency scenario, senior lenders and trade creditors are paid before the seller note holder. If the business is wound down with insufficient assets to cover all obligations, the seller may receive little or nothing on the note. This risk is why savvy sellers negotiate for: security interest in business assets (if the buyer will agree), personal guarantees from the buyer or principals, regular reporting requirements so the seller can monitor the business's financial health, and acceleration clauses that allow the seller to call the note if certain financial covenants are breached.
