Selling any business takes effort. But once you move into seven figures, the process becomes noticeably different. Buyers expect more. The due diligence is deeper. The documents need to be stronger. And the stakes — for both sides — are higher.
This post explains what changes when a UK business sale moves past the £1 million mark, and what sellers need to do differently to be ready.
The Short Answer
Selling a business for over £1 million usually means buyers will expect better financial records, clearer adjusted EBITDA, stronger contracts, deeper due diligence, more professional negotiation, and more detailed legal documents.
The seller will typically need stronger preparation before going to market — including management accounts, forecasts, add-back evidence, customer concentration analysis, staff records, legal contracts, tax planning, a document pack, and in some cases an information memorandum.
A seven-figure business can still be owner-managed and suitable for a marketplace or broker route. But if the sale involves strategic buyers, private equity, multiple shareholders, complex contracts, earn-outs or sensitive confidentiality issues, corporate finance or M&A support is worth seriously considering.
Why Seven-Figure Sales Feel Different
At lower values, buyers are often willing to tolerate some messiness if the business is simple and easy to understand. They can get comfortable with limited paperwork, informal accounts and an owner who plays a central role in everything.
At seven figures, that tolerance largely disappears.
Buyers at this level are typically more sophisticated. They're putting a significant amount of capital at risk — their own money, a bank's money, or a private equity fund's money. They need evidence, not just a story.
They're likely to ask:
Are the accounts accurate and up to date?
Is the profit maintainable without the current owner?
Are the add-backs credible?
Are contracts transferable to a new owner?
Are key staff likely to stay?
Is customer concentration acceptable?
Are there any tax or VAT risks?
Are there any disputes, claims or litigation?
What happens to the business if the owner leaves?
Is the asking price supported by evidence?
Can finance actually be raised to support this deal?
A £1m+ asking price doesn't require perfection. But it does require evidence.
What Buyers Will Expect
Buyers in this price range may expect to see:
Three years of statutory accounts
Recent management accounts (ideally within the last month or two)
An adjusted EBITDA calculation with a clear add-back schedule
Revenue forecasts or a pipeline summary
A customer analysis showing concentration and retention
Copies of key contracts
Staff records and organisational chart
Lease and property information
Tax and VAT records
An asset list
Working capital analysis
A clear handover plan
They may also expect the seller to understand the difference between key deal terms — headline price, enterprise value, equity value, debt-free/cash-free price, working capital adjustment, deferred consideration, earn-out and retention. The more sophisticated the buyer, the more these distinctions matter.
Financial Preparation: Getting It Right
For a seven-figure sale, financial preparation needs to be stronger than for a smaller deal. The documents that matter include:
Statutory accounts (three years if possible)
Management accounts (recent and clear)
Monthly revenue and profit breakdown
Gross margin analysis
Revenue by customer, product or service
Adjusted EBITDA with a clear add-back schedule
Owner salary normalisation
Forecasts and pipeline or order book
Debtor and creditor reports
Working capital analysis
Debt schedule
Tax and VAT records
Payroll records
A Word on Add-Backs
Add-backs — costs added back to profit to show "true" underlying earnings — need to be credible. Weak or poorly evidenced add-backs can damage buyer trust very quickly.
Items that are commonly challenged include normal marketing spend, normal repairs and maintenance, underpaid staff costs (where the buyer sees the real market cost), owner salary that's been completely removed, recurring software costs, standard professional fees and ordinary business travel.
Buyers will typically accept genuine one-off or personal costs with clear evidence. But they'll test everything.
Valuation: Evidence Matters
At seven figures, a valuation needs to be supported by real evidence, not just potential.
A strong valuation explanation looks something like this:
*"The asking price is based on adjusted EBITDA of £350,000, using a multiple of approximately 3.2x, supported by recurring revenue, low customer concentration and a management team that can continue after completion."*
A weak one looks like this:
*"We want £1.2m because the business has huge potential."*
Potential without evidence is not a valuation. Buyers at this level know the difference, and sellers who can't explain the numbers clearly will struggle.
What supports a seven-figure valuation:
Maintainable profit with evidence
Sector-appropriate multiples
Evidence of growth
Recurring revenue and strong customer retention
Contracts in place
Staff continuity
Reduced owner dependency
Clean risk profile
Due Diligence Gets Deeper
At this level, buyers typically carry out thorough due diligence. They may review:
Financial records in detail
Tax, VAT and PAYE
Payroll and pension records
Legal contracts
Lease and property documents
Staff records and TUPE implications
Customer and supplier contracts
Litigation and disputes
Insurance
Data protection and cybersecurity
Licences and regulatory matters
Environmental issues
Intellectual property
Working capital
Completion accounts
If private equity or corporate buyers are involved, the due diligence is likely to be formal, structured and adviser-led on the buyer's side. The seller needs to be equally well-prepared on theirs.
Deal Structure: Don't Focus Only on Headline Price
At seven figures, buyers frequently use deal structure to manage their risk. This is something sellers sometimes underestimate.
Common deal terms at this level include:
Deferred consideration— part of the price paid after completion, often tied to conditions
Earn-out— payments linked to future performance targets
Seller finance— the seller lends part of the price to the buyer
Retention— a portion held back pending warranty claims
Escrow— funds held by a third party
Completion accounts— final price adjusted based on actual figures at completion
Warranties and indemnities— contractual protections for the buyer
Non-compete— restrictions on what the seller can do after leaving
Consultancy handover— the seller stays involved for a defined period
A seller should never focus solely on the headline price. A £1.2m offer with £800,000 deferred and vague earn-out terms may carry far more risk than a cleaner £1m all-cash offer.
Tax and Legal Planning: Start Early
Tax and legal planning should happen before the deal structure is agreed — not after.
Issues that commonly arise at this level include:
Share sale vs asset sale (which has very different tax consequences)
Business Asset Disposal Relief eligibility
Corporation Tax on any gain
Capital Gains Tax treatment
VAT and the Transfer of Going Concern rules
Stamp taxes
Director loan accounts
Shareholder agreements
Tax treatment of earn-outs and deferred consideration
Warranty and indemnity insurance
On Business Asset Disposal Relief specifically: the rate for qualifying gains on disposals on or after 6 April 2026 is 18%. Sellers should never assume the relief applies without taking proper advice — the conditions are specific and not always met.
Legal planning also matters because larger sales involve stronger buyer protections. The share purchase agreement or asset purchase agreement at this level is typically far more detailed than those in smaller transactions.
When to Consider M&A or Corporate Finance Advice
A broker or marketplace may still be the right route for a seven-figure business if it's straightforward and owner-managed. But consider M&A or corporate finance support if:
Value is several million pounds
EBITDA is strong and needs positioning carefully
Strategic buyers exist who wouldn't find the business through a listing
Private equity may be interested
Buyer outreach needs to be targeted and confidential
An information memorandum is needed
Multiple bidders are possible and you want to create competition
Vendor due diligence would add confidence to the process
There are multiple shareholders to coordinate
Deal structure is complex or earn-out terms are likely
The seller needs negotiation support
A broker or marketplace may still be useful alongside this — but larger sales often need a more structured, actively managed process.

FAQs
Can I sell a business for over £1m on a marketplace?Yes, if the business is suitable and confidentiality is managed carefully. But larger or more complex deals may need adviser support alongside the marketplace visibility.
Does a £1m sale always need an M&A adviser?No. A straightforward owner-managed business may not need full M&A support. Complexity and buyer type matter as much as the price.
What do buyers expect at this level?Clear financials, an evidence-backed valuation, contracts in order, staff records, tax and VAT records, risk disclosure and a professional process.
Should I prepare an information memorandum?Possibly. If the business is complex or being marketed to strategic buyers, an IM can help present the business case clearly and reduce repeated buyer questions.
Is headline price the most important thing?No. Payment structure, payment certainty, deferred terms, tax treatment, warranties and completion risk can all matter more than the number on the page.
Key Takeaways
Seven-figure business sales need stronger evidence and better preparation than smaller deals. Buyers expect clean financials, credible adjusted EBITDA, well-organised documents and a professional process. Add-backs must be evidenced. Deal structure matters as much as headline price. Tax planning should start early — ideally before any deal terms are discussed. And while a marketplace can still help, complex deals at this level often benefit from M&A or corporate finance support alongside it.
