How a Business Sale Price Is Structured: Deferred Consideration, Earn-Outs and More

When selling a business, the headline valuation is only half the story. The real question is how and when you will actually receive your funds. In mergers and acquisitions, purchase price structures heavily influence risk, tax liabilities, and the likelihood of the deal closing.

A buyer rarely writes a single, unconditional cheque on completion. Instead, negotiations often focus on balancing the buyer’s desire to mitigate risk against the seller’s desire for guaranteed, immediate payment of funds. Understanding the primary ways a purchase price can be structured, along with the pros and cons of each from both sides of the table, is essential for any business owner preparing for a successful corporate disposal. Before negotiating any of these structures, it is worth making sure the business itself is legally ready for sale — see our guide to preparing your business for sale.

1. Upfront Cash on Completion

This is the most straightforward payment mechanism, where the buyer pays the entire agreed purchase price, or the vast majority of it, in cash immediately upon signing the completion documents.

From the seller’s perspective, upfront cash provides maximum transaction certainty and immediate financial liquidity. The seller achieves a clean break from the company and avoids the ongoing risk of a buyer defaulting on future payments or mismanaging the business post-sale. However, the downside is that buyers usually demand a significant discount on the overall business valuation in exchange for taking on one hundred percent of the operational risk from day one.

From the buyer’s perspective, this mechanism allows them to gain total, unencumbered control of the company from the completion date without lingering financial obligations or reporting requirements to the former owner. On the downside, this option requires a massive upfront capital outlay, which can severely strain cash reserves or necessitate expensive third-party acquisition financing.

2. Deferred Consideration

Under a deferred consideration structure, a portion of the purchase price is paid at fixed, agreed intervals after the completion date. Unlike an earn-out mechanism, these future payments are guaranteed and are not dependent on the subsequent financial performance of the business.  For example, the parties agree a purchase price of £1M for a business.  The buyer pays £750,000 at completion and the balance of £250,000 is paid in four equal instalments over a two year period.

For the seller, accepting deferred payments can attract a wider pool of potential buyers and often allows the seller to negotiate a higher overall headline purchase price. The major drawback is that the seller effectively becomes an unsecured creditor to the buyer. If the buyer faces financial distress or corporate insolvency post-completion, the seller faces a genuine risk of never receiving the remaining balance. Therefore, sellers must work with a corporate lawyer to secure corporate guarantees or charges over assets to mitigate this risk.

For the buyer, this structure significantly eases immediate cash flow pressures by spreading the acquisition cost over a longer period. It also gives the buyer financial leverage, because if they discover a breach of warranty or indemnity after completion, they can potentially look to set off those legal claims against the future deferred payments. The disadvantage for the buyer is that the payment obligation remains absolute, meaning that even if the business underperforms dramatically after the sale, the buyer is still legally obligated to pay the full agreed amount.

3. Earn-Out Structures

An earn-out structure makes a portion of the purchase price conditional upon the business achieving specific financial milestones, such as gross profit or EBITDA targets, over a set period post-completion.  Typically, the payment is structured in similar terms to the example provided above, save that the amount of the deferred element of the purchase price will be linked to the ongoing financial performance of the business.  If it underperforms the balance of the purchase price will be adjusted downwards. Where the business overperforms, the value of the deferred element of the price paid to the seller will increase.

From the seller’s perspective, an earn-out is an excellent tool to bridge a valuation gap if the seller believes the business is poised for massive growth that the buyer is unwilling to pay for upfront. However, the risk is that sellers lose operational control but remain entirely dependent on the buyer’s management style to hit their targets. If the buyer integrates the business poorly, alters successful marketing strategies, or loads the company with corporate overheads, the performance targets may become impossible to reach, resulting in costly legal disputes.

From the buyer’s perspective, this mechanism aligns the seller’s financial interests with the buyer’s post-acquisition success. It effectively protects the buyer from overpaying for a company that cannot sustain its historic profitability once the original founder departs. The main disadvantage for the buyer is that earn-outs require highly complex legal drafting and ongoing monitoring, which frequently lead to post-completion litigation regarding how accounting metrics are calculated and whether the buyer acted in good faith.

Buyer Equity and Rollover Shares

In many mid-market transactions, particularly those involving Private Equity buyers, sellers can be required to exchange a portion of their sale proceeds for shares of the buyer’s purchasing company.

For the seller, this offers the lucrative potential for a second bite of the cherry. If the private equity firm grows the combined group and executes a secondary sale a few years later, the seller’s retained equity could finish worth significantly more than the original cash value. Conversely, the downside is that the seller holds a minority stake with virtually no operational control, meaning that if the buyer’s overarching corporate strategy fails, that rolled-over equity can easily become entirely worthless.

For the buyer, this structure preserves precious acquisition cash and guarantees that the founding entrepreneur remains financially motivated to support the business transition and protect its enterprise value. The disadvantage for the buyer is that they must welcome the former owner into their corporate governance structure as a shareholder, which requires drafting complex shareholder agreements and managing minority shareholder rights.

Vendor Loans and Loan Notes

A vendor loan occurs when the seller leaves a portion of the purchase price in the company as a formal loan to the buyer. This arrangement is formalised through a Loan Note, which typically accumulates interest over a fixed term.  Using the example provided above, in this scenario the deferred element of the purchase price effectively becomes an interest-bearing loan payable by the buyer.

From the seller’s perspective, a vendor loan facilitates a deal that might otherwise collapse due to a lack of buyer funding, while providing the seller with a steady stream of interest income that often beats traditional bank rates. However, the primary disadvantage is that vendor loans are almost always subordinated to the buyer’s primary bank lenders. If the company fails post-sale, the bank gets paid first, leaving the seller highly exposed to a total financial loss.

From the buyer’s perspective, a vendor loan bridges critical funding gaps when banks are reluctant to lend the full acquisition amount. It also serves as a strong vote of confidence, demonstrating that the seller has genuine faith in the company’s ongoing financial health. The downside is that the buyer’s balance sheet carries additional debt, and the business must generate sufficient cash flow to cover both the principal repayments and the accumulating interest.

Concluding remarks

There is no single correct way to structure a business sale. The optimal structure depends entirely on your cash requirements, your tolerance for risk, and your timeline for exiting the business. Navigating these options requires early collaboration with experienced corporate lawyers and tax advisors to ensure you do not leave money on the table during deal negotiations.
