M&A Deal Structuring: Earnouts, Seller Notes, and Cash at Close

M&A deal structuring is the part of a sale that decides how much of your price you actually keep, when you receive it, and how much risk you carry to get it. Two offers with the same headline number can produce very different outcomes once you account for how the money is paid. The three most common building blocks are cash at close, earnouts, and seller notes, and each shifts risk between you and the buyer differently. At True North Mergers & Acquisitions (TNMA), we negotiate the whole structure, not just the top-line price, because seller-friendly terms are often where a deal is won or lost when selling a business. This guide explains each structure, with the pros and cons of each.

What Is M&A Deal Structuring?

M&A deal structuring is the design of how a purchase price is paid, combining components like cash at close, earnouts, seller notes, rollover equity, and escrow into a complete transaction. The total price gets the attention, but the structure determines what that price is really worth to you. Rollover equity, where you retain a minority stake in the business after closing, and escrow, where a portion of the price is held back against post-closing claims, are also common components; this guide focuses on the three that most often determine what a seller actually collects.

At its core, deal structure is about risk allocation. It decides who carries the risk of the company's future performance, the buyer's ability to pay, and the accuracy of the numbers presented in diligence.

A larger price paid mostly through contingent, deferred components can be worth less than a smaller price paid mostly in cash, because you may never collect the contingent part. Understanding each component lets you compare offers on their real, risk-adjusted value rather than their headline figures. The three core structures that most often determine what a seller collects are cash at close, earnouts, and seller notes.

Cash at Close

Cash at Close: The portion of the purchase price paid in full, in cash, at the closing of the sale, with no conditions attached.

Cash at close is the most certain money in any deal. Once the transaction closes, it is yours, with no dependence on the buyer's future performance, solvency, or good faith.

For most sellers, maximizing the cash paid at closing is the single most reliable way to protect the value of a sale, which is why the percentage of a deal paid in cash is one of the most important terms to negotiate.

Pros for the seller:

• Certain and immediate, with no future collection risk.
• No reliance on the buyer's post-closing performance or solvency.
• Settles the tax outcome at closing rather than spreading it over future years, though the character of the gain depends on deal structure and purchase price allocation.

Cons for the seller:

• Buyers may offer a lower total price in exchange for an all-cash structure.
• Insisting on all cash can narrow the pool of buyers who can meet that demand.
• A large gain concentrated in a single tax year can raise your effective tax rate, so coordinate timing with your CPA.

Earnouts

Earnout: A portion of the purchase price paid after closing, contingent on the business achieving agreed performance targets, such as revenue or EBITDA, over a defined period, often one to three years.

An earnout in a business sale bridges a gap between what you believe the company is worth and what a buyer will pay today. Rather than settle the disagreement at closing, the parties agree that you will receive additional consideration if the business hits defined targets after the sale.

An earnout can raise your total potential price, but the payment is never guaranteed, and you often have limited control over the business once the buyer owns it.

Pros for the seller:

• Can bridge a valuation gap and increase the total potential price.
• Lets a confident owner share in the upside the business is likely to deliver.
• Can make a deal possible that a fixed price alone would not.

Cons for the seller:

• Payment depends on future results and is never certain.
• You may not control the decisions that drive the targets after closing.
• In our experience, disputes over how performance is measured are common.
• Depending on how it is written, an earnout may be taxed as ordinary income rather than capital gain, and even a well-structured earnout carries an imputed interest component taxed at ordinary rates. It can also keep you tied to the business.

Seller Notes and Seller Financing

Seller Note (Promissory Note): A loan from the seller to the buyer that covers part of the purchase price, documented as a promissory note and repaid with interest over an agreed term.

A seller note, also called seller financing, means you act as a lender for part of your own sale. The buyer pays a portion of the price over time, with interest, under the terms of a promissory note. In our experience, seller financing is common in the lower middle market, where it can close a gap between the buyer's available capital and the purchase price, or signal your confidence in the business to a cautious buyer.

Should you offer seller financing? It depends on the buyer's creditworthiness, the security you can obtain, the interest rate, and how much certainty you need. A seller note can help close a deal and earn interest income, but it defers part of your proceeds and exposes you to buyer default, so it should be secured, priced for the risk, and reviewed by your M&A attorney.

Pros for the seller:

• Can close a valuation or financing gap and keep a deal alive.
• Earns interest income on the deferred amount.
• Pays on a set schedule regardless of performance, unlike an earnout.

Cons for the seller:

• Defers part of your proceeds and carries the risk that the buyer defaults.
• Ranks behind the buyer's senior lender, so you are paid after the bank.
• Generates interest income taxed at ordinary rates.
• Requires security, covenants, and legal work to protect you.

How Do Transaction Terms Affect Your Net Proceeds?

Transaction terms affect your net proceeds by determining how much of the headline price you actually collect, when you collect it, and how it is taxed. The price is only a starting point. The structure decides the rest.

Consider the same $20 million offer paid in two ways. All cash at closing gives you certainty and a single capital-gains event. The same total split into cash, a three-year earnout, and a subordinated seller note gives you less certainty, a longer collection period, and a mix of tax treatments, since interest and some earnout payments can be taxed as ordinary income rather than capital gain.

Deferred consideration also carries the risk that you never collect it in full. This is why a lower all-cash offer can leave you better off than a higher offer loaded with contingent terms. The goal is not the largest headline number, but the strongest Net After-Tax (NAT) proceeds on a risk-adjusted basis. Because these are tax questions with real consequences, model them with your CPA before you agree to any structure.

How We Negotiate Deal Structure on Your Behalf

At True North Mergers & Acquisitions, we treat structure as a primary negotiation, not a detail settled at the end. Many sellers focus on price and accept whatever terms come attached. We work the terms just as hard as the number, because that is often where the real value sits.

In practice, that means pushing for more cash at closing, and where contingent consideration is used, negotiating protections around it. For earnouts, we press for clear, measurable targets defined in your favor, along with acceleration if the buyer sells the business or changes the way it is run. For seller notes, we seek appropriate security, interest, and covenants so you are protected if the buyer struggles.

We keep escrow amounts and release timelines reasonable, and we coordinate with your CPA and M&A attorney so the structure protects your NAT proceeds rather than eroding them. A competitive QuietAuction™ process gives you the negotiating position to win these terms, because buyers competing for your company are typically willing to accept more seller-friendly structures than a single unchallenged buyer would.

Frequently Asked Questions

Key Takeaways

• Cash at close is the only certain consideration in a transaction, which makes the percentage of the price paid in cash the term worth pushing hardest.
• An earnout can raise your total potential price, but it transfers performance risk to a seller who no longer controls the business.
• A seller note pays on a fixed schedule regardless of performance, but it usually ranks behind the buyer's senior lender.
• Two offers with the same headline number can differ materially in Net After-Tax proceeds once structure, timing, and tax treatment are modeled.

Structure Your Deal to Keep More of What You Earn

M&A deal structuring is where the outcome is decided, not the headline price where most sales conversations start. Cash at close, earnouts, and seller notes each shift risk and taxes in ways that can add to or erase real value after the deal is done. Negotiating those terms well and modeling their after-tax effect before you sign is what separates a good price from a good outcome. If you are preparing to sell, our team can help you weigh the structures and negotiate the terms that protect what you keep.
