In short: what should you negotiate when selling a business?
When selling a business, owners should negotiate far more than the headline valuation. The key terms are whether the price is an enterprise value or an equity value, how cash, debt and working capital are treated, and how much is paid at completion. Any deferred consideration, earn-out or retained equity needs clear terms, and the buyer's funding and conditions determine how certain the offer is. Warranties and indemnities, restrictive covenants, the owner's role after the sale, exclusivity and the completion timetable all affect the outcome too.
A business sale should be evaluated on total economic outcome, risk and certainty, not headline price alone.
Why the Highest Offer Is Not Always the Best Offer
Consider two illustrative offers for the same business. These are hypothetical figures, not a real transaction.
| Offer A | Offer B | |
|---|---|---|
| Headline value | £5.0m | £4.7m |
| Paid at completion | £3.0m | £4.5m |
| Deferred consideration | £1.0m | £0.2m |
| Earn-out | £1.0m | None |
Offer A looks £300,000 higher, but £2.0m of it depends on the buyer paying later and the business hitting earn-out targets. Offer B pays almost everything at completion. Offer B could provide greater certainty and less risk; Offer A could deliver more if the business performs and the buyer is strong. Neither is universally better. The right answer depends on the owner's priorities and on the detail behind each offer. Owners should compare:
- Cash at completion
- Certainty that the deal will complete
- The number and nature of conditions
- Risk attached to deferred payments
- How achievable any earn-out really is
- How the buyer is funding the deal
- Liabilities the seller retains
- Future upside from any retained equity
- Tax consequences, which are a matter for your tax adviser
- Time to completion
Enterprise Value Is Not Necessarily What the Shareholder Receives
Most offers for UK private companies are expressed as an enterprise value: the value of the trading business independent of how it is financed. What shareholders receive is the equity value, after the transaction adjustments. In simple terms:
+ surplus cash
− debt and debt-like items
± working capital adjustment
= equity value
Actual definitions vary by transaction and are set out in the sale agreement. See how UK businesses are valued and what happens to the cash in the bank when you sell.
What Does Cash-Free, Debt-Free Mean?
Cash-free, debt-free means the buyer prices the business as if it had no cash and no borrowing, then the price is adjusted: surplus cash is usually added and debt deducted, on the assumption that a normal level of working capital is left in the business. Many UK private-company transactions are negotiated on this basis.
The words sound simple; the detail is often contentious, because each side has an interest in what counts as cash and what counts as debt. Depending on the transaction, items that may need agreement include bank debt, shareholder loans, asset finance, overdue tax, accrued bonuses, unpaid dividends, customer deposits, deferred income, leases, provisions and transaction costs. No item is automatically treated one way or the other; the definitions depend on the negotiation and the sale agreement.
Why Working Capital Can Change What You Receive
Buyers expect the business to be handed over with enough working capital (broadly, stock and debtors less trade creditors) to trade normally. The parties agree a normal working capital target, often called the peg, and the price is adjusted if the actual working capital at completion is above or below it.
As an illustration: if the agreed target is £800,000 and working capital at completion is £650,000, the price may be reduced by £150,000; if it is £900,000, the seller may receive £100,000 more.
How the target is set matters. Seasonal businesses can show very different positions depending on the month used; growing businesses often need more working capital each year; and unusual debtor or creditor positions can distort an average. Agreeing a headline valuation without understanding the working capital mechanism can move a meaningful sum away from the seller.
How Much Will You Actually Receive on Completion?
Owners should distinguish the total headline consideration, the equity value, the completion payment, deferred payments, any earn-out, rollover equity and any retention or escrow held back against claims.
| Element | Paid at completion? | Main seller risk |
|---|---|---|
| Cash consideration | Usually | Lowest once funds clear |
| Deferred consideration | No | Buyer credit or default risk |
| Earn-out | No | Performance and control risk |
| Rollover equity | No | Future business and investment risk |
| Retention or escrow | Held back | Claims made against it |
The tax treatment of each element can differ and should be discussed with your tax adviser.
Deferred Consideration
Deferred consideration is part of the price paid after completion, on set dates or when conditions are met. £1 paid in two years is not economically identical to £1 paid at completion: it carries the risk that the buyer cannot or will not pay, and it cannot be used in the meantime. Points to negotiate include:
- Payment dates and whether payments are fixed or conditional
- Security or guarantees supporting payment
- The buyer's covenant strength
- Interest on outstanding amounts
- Acceleration if the buyer sells the business or defaults
- Whether the buyer can set off claims against payments
- What happens on a change of control of the buyer
- Default provisions
Earn-Outs: Price or Risk?
An earn-out makes part of the price depend on the business's performance after completion. Buyers use them to bridge a valuation gap, to share the risk of forecast growth, where value depends heavily on the founder, where a customer pipeline is not yet contracted, or where integration makes future results uncertain.
For the seller, an earn-out is price with risk attached. A term such as "£1m if EBITDA reaches £X" means little unless EBITDA itself is precisely defined. The points to focus on are:
- The metric, and exactly how it is calculated
- The measurement period
- Which accounting policies apply
- Who controls costs, and how management remuneration and intra-group charges are treated
- Investment decisions that affect performance
- Obligations on the buyer's conduct of the business
- Information rights for the seller
- The seller's role and what happens if it ends
- How disputes are resolved
- When payments are made
Earn-outs work best where the metric is simple, the period short and the seller retains real influence over the result.
Discuss Your Transaction Options
Structure matters as much as price. A confidential conversation can help you understand which terms are likely to matter most for your business.
Retained Equity and the Second Sale
Many sales leave the owner with shares: rollover equity in a buyer's structure, a retained minority after a majority stake sale, a larger holding after a minority stake sale, or a planned two-stage exit. Retained equity can be the most valuable part of the deal, so it should be negotiated as carefully as the initial cash payment. The commercial questions include:
- The percentage retained and the valuation on entry
- Dilution and how future funding is provided
- Board and information rights
- Dividend policy
- Drag-along and tag-along rights
- How and when a future sale happens, and how value is then determined
- The buyer's intended exit and timescale
See partial business sales for how these deals are structured.
Is the Buyer Actually Funded?
A price means little if the buyer cannot fund completion. A cash buyer, a trade buyer using debt, and a private equity-backed buyer needing investment committee and lender approval carry different levels of risk. Understanding the source of funds, internal board or committee approvals, acquisition finance and any funding conditions is part of qualifying a buyer, and should happen before exclusivity is granted. Trade buyers and private equity investors typically fund deals differently. An adviser can test and question a buyer's funding position but cannot guarantee it.
What Conditions Sit Behind the Offer?
Offers commonly depend on conditions such as:
- Satisfactory due diligence
- Buyer funding
- Board or investment committee approval
- Landlord or customer consents
- Regulatory approval
- Satisfactory legal documentation
- Retention of key staff
- Completion accounts
- Minimum trading performance
Some conditions are normal. But an apparently high offer with many subjective conditions can provide less deal certainty than a slightly lower offer with few. Preparing with a due diligence checklist reduces the scope for open-ended diligence conditions.
What Should Be Agreed in Heads of Terms?
Heads of terms should record the key economics clearly: the headline valuation and whether it is an enterprise or equity value, the treatment of cash, debt and working capital, the completion payment, deferred consideration, any earn-out and rollover, management arrangements, exclusivity, the scope of due diligence, the timetable and the major conditions. Commercial ambiguity at this stage often resurfaces during legal drafting, when the seller has less leverage. For the legal side, see legal considerations when selling a business.
When Should You Give a Buyer Exclusivity?
Buyers ask for exclusivity so they can spend money on due diligence and legal work without competing bidders. For the seller, it means competitive tension disappears, the buyer has more room to retrade, the process can stall, other bidders cool, and the seller becomes dependent on one outcome. Terms worth negotiating include the duration, milestones, the scope of information requests, evidence of funding, the timetable and whether and how it can be extended. This is a commercial negotiation; the exclusivity wording itself should be handled by your solicitor.
What Is Retrading?
Retrading is when a buyer attempts to reduce the price or worsen the agreed commercial terms after the seller has invested time in the transaction, often during or after due diligence.
Sometimes it is legitimate: a previously undisclosed issue, a deterioration in earnings, the loss of a customer or a material liability. Sometimes it is tactical: waiting until exclusivity, repeatedly changing assumptions, treating known information as new, or using minor findings disproportionately. Preparation, early disclosure, competitive tension and disciplined negotiation all reduce a seller's vulnerability. See whether a buyer can reduce their offer during due diligence.
How Do You Increase Deal Certainty?
- Qualify buyers before engaging deeply
- Verify funding and understand the buyer's decision process
- Prepare information early and identify problems before due diligence
- Agree the key economics in heads of terms
- Maintain momentum through the process
- Avoid premature exclusivity
- Keep alternatives alive where appropriate
- Use experienced legal and tax advisers
A good sell-side adviser should improve not just the valuation but the probability of completion. See the sell-side process.
How Long Do You Need to Stay After the Sale?
There is no standard period. Arrangements range from an immediate exit or short handover to a consultancy, an employment contract, a continuing management role or a retained shareholder role. The owner should negotiate the role, authority, hours, remuneration, duration and termination terms, and how these interact with any earn-out or retained equity.
Restrictions After Completion
Buyers usually seek restrictions on the seller competing with the business, approaching its customers, employees or suppliers, and using its confidential information. Their scope and length should fit your future plans; your solicitor will advise on the drafting. See legal considerations when selling a business.
Price Is Only One Part of Seller Risk
Two offers with the same headline price can leave the seller with very different levels of risk after completion. Beyond the price, sellers should understand their exposure under the warranties, any specific indemnities, the caps on liability and the time limits for claims, whether part of the price is held in escrow or retention, whether the buyer can set off claims against deferred consideration, how claims are made and whether future payments could be withheld. These are negotiated commercially and documented by your solicitor; the legal side is covered in legal considerations when selling a business.
Negotiating a Partial Sale Is Different
When an owner retains equity, the future shareholder relationship can be as important as the price paid on day one. A partial sale means negotiating both the initial transaction and the terms on which the seller and the incoming investor or purchaser will own the business together, whether through a majority stake sale, a minority stake sale, a two-stage exit or a strategic partner investment. The points to agree include:
- The percentage sold and who has control
- Reserved matters that need both parties' agreement
- Board representation and information rights
- Dividend policy
- Future funding and protection against dilution
- The owner's management role and remuneration
- Strategic direction
- Drag-along and tag-along rights, at a high level
- How the retained equity will be valued and when a future sale is expected
How to Compare Business Sale Offers
To compare business sale offers, set them side by side term by term rather than ranking them on headline value. The purpose is to compare economics, certainty, timing, conditionality, future upside and seller exposure. A framework like the one below, completed for each real offer, makes the differences visible.
| Term | Buyer A | Buyer B |
|---|---|---|
| Headline value | ||
| Cash at completion | ||
| Deferred fixed consideration | ||
| Earn-out | ||
| Retained equity | ||
| Cash/debt treatment | ||
| Working capital mechanism | ||
| Funding certainty | ||
| Due diligence conditions | ||
| Management commitment | ||
| Exclusivity requested | ||
| Expected timetable | ||
| Post-completion seller risk | ||
| Overall execution risk |
The table is deliberately left blank: it is a checklist of questions, not a scoring system. Completed honestly, it often shows that a lower headline offer can produce a better economic outcome once cash at completion, risk and certainty are taken into account.
What Matters Most When Negotiating a Business Sale?
Different shareholders legitimately prioritise different outcomes, and there is no single correct answer. Priorities can include maximum total value, maximum cash at completion, deal certainty, speed, reducing personal risk, retaining future upside, remaining involved or stepping away quickly, protecting employees, maintaining the business's identity and finding the right strategic partner. These should be understood before serious negotiation begins, because an adviser cannot negotiate effectively if the owner's real priorities are unclear, and shareholders may not all want the same thing.
Common Mistakes When Negotiating a Business Sale
Focusing only on headline price
The number that matters is what you receive, when, and with what risk.
Granting exclusivity too early
Competitive tension is the seller's main source of leverage.
Failing to establish buyer funding
An offer the buyer cannot fund is not a real offer.
Agreeing vague earn-out terms
Undefined metrics tend to be resolved in the buyer's favour later.
Ignoring working capital
The peg can move a meaningful sum at completion.
Misunderstanding cash and debt
Definitions of debt-like items directly change equity value.
Accepting long deferred payments without considering protection
Security, guarantees and default terms matter.
Treating rollover equity as if it were cash
Its value depends on future performance and a future sale.
Failing to negotiate retained-equity rights
Minority shareholders need agreed protections.
Allowing due diligence to drift
Long processes give more room for retrading and deal fatigue.
Reacting emotionally to every buyer request
Most requests are routine; judge them on substance.
Allowing one buyer to control the timetable
Agree milestones and keep the seller's timetable in view.
Negotiating before properly preparing the business
Issues found late cost more than issues disclosed early.
Assuming an indicative offer is a deliverable completion price
Indicative offers are subject to diligence and conditions.
Most of these are avoided through preparation; see how to prepare a business for sale.

Business Sale Negotiation FAQs
Should I accept the highest offer for my business?
Not automatically. Headline price is only one element of an offer. It should be weighed alongside how much is paid at completion, the risk attached to deferred payments and earn-outs, the buyer's funding, the conditions attached and how likely the deal is to complete.
What is the difference between enterprise value and equity value?
Enterprise value is the value of the trading business regardless of how it is financed. Equity value is what the shareholders receive: enterprise value plus surplus cash, minus debt and debt-like items, adjusted for working capital. Definitions vary by transaction.
What does cash-free, debt-free mean?
It means the business is priced as if it had no cash and no debt, then the price is adjusted: surplus cash is usually added and debt deducted, assuming normal working capital is left in the business. What counts as cash and debt is negotiated. Our Cash in the Bank guide explains this in detail.
What is a working capital adjustment?
It compares the working capital actually in the business at completion with an agreed normal level, often called the peg. If completion working capital is below the peg the price usually falls; if it is above, the price may rise.
How much of the sale price should be paid at completion?
There is no universal percentage. The split between completion, deferred and contingent payments depends on the buyer, the business, how risk is allocated and what is negotiated. Sellers should compare offers on the cash actually received at completion, not only the headline figure.
Is deferred consideration risky?
Yes, to a degree. Deferred consideration depends on the buyer being willing and able to pay later, so the seller takes on buyer credit risk. Payment dates, security, guarantees, set-off rights and default provisions all affect how risky it is.
Should I agree to an earn-out?
An earn-out can bridge a genuine difference in valuation, but it creates future performance and control risk for the seller. It is more acceptable when the metric is precisely defined, the period is short and the seller keeps real influence over the result.
What is rollover equity?
Rollover equity is where a seller reinvests, or keeps, part of their economic interest in the business or the acquiring group instead of taking it all as cash. Its value depends on the future performance of that business and on how a later sale happens.
When should I give a buyer exclusivity?
Exclusivity is normally considered once the key commercial terms are agreed in heads of terms and the buyer's credibility and funding are sufficiently established. It should be limited in time and tied to a timetable.
What happens if the buyer reduces the offer after due diligence?
This is known as retrading. A reduction can be justified by a genuine new finding, such as a material liability or loss of a customer, or it can be tactical. Sellers should ask for the reasoning in writing and test whether the issue was genuinely unknown.
How do I know whether a buyer has the money?
Ask for evidence of funds, understand whether the buyer relies on debt or investor money, and find out which lender, board or investment committee approvals are still needed. This reduces risk, but no adviser can guarantee that completion funding will be available.
Can I negotiate how long I stay after the sale?
Yes. Your role, authority, duration, remuneration and termination terms are all negotiable, and they should be consistent with any earn-out or retained equity that depends on your involvement.
What happens if I retain shares?
You become a shareholder alongside the buyer or investor. Governance, protection against dilution, dividend policy, information rights and the terms of any future exit then determine what those shares are worth to you.
Who negotiates the commercial terms of a business sale?
The owner decides. The sell-side M&A adviser negotiates and coordinates the commercial deal, the solicitor turns it into legally enforceable documents and advises on legal risk, and the tax adviser advises on the tax consequences of the structure.
