How to Structure a Deal to Buy a Business

Written by Paul Griffiths | May 28, 2026, 5:35:38 PM

A business acquisition does not always need to be funded entirely in cash on completion. A typical deal structure may combine the buyer's personal capital, acquisition finance, deferred consideration, seller finance, retained equity and, in some cases, an earn-out. The right structure depends on the target company's cash flow, EBITDA, valuation, funding capacity and the seller's objectives.

Part of the deal structure What it means
Buyer capital Money invested personally by the buyer
Acquisition finance External debt used to fund part of the purchase
Completion payment Amount paid to the seller when the deal completes
Deferred consideration Agreed purchase price paid after completion
Seller finance Part of the price effectively financed by the seller
Earn-out Additional payment dependent on future performance
Retained equity Seller keeps a minority shareholding after completion
Investor equity External investor provides capital in return for ownership

When you are buying a business, agreeing the valuation is only one part of the transaction.

You also need to work out how the purchase will actually be funded.

A business may be valued at £1 million, but that does not necessarily mean the buyer needs £1 million in cash on day one.

Instead, the transaction can often be structured using several different sources of capital.

The objective is to create a deal that:

  • The seller is prepared to accept
  • The buyer can afford
  • The business can support
  • The lender is comfortable funding
  • Leaves enough cash in the company to continue operating after completion

This guide explains how to structure a deal when buying a business and the main factors that can determine how much is paid at completion and how much can be funded over time.

 

What Does Deal Structure Mean When Buying a Business?

The deal structure describes how the acquisition price is paid and how ownership transfers from the seller to the buyer.

For example, a £1 million acquisition might be structured as:

  • £100,000 buyer capital
  • £500,000 acquisition finance
  • £250,000 deferred consideration
  • £150,000 seller finance

Alternatively, the buyer might purchase only 80% of the shares initially, leaving the seller with a 20% retained equity stake.

Two deals can therefore have exactly the same headline valuation but create very different funding requirements.

 

What Determines How a Business Acquisition Is Structured?

There is no single structure that works for every acquisition.

The right structure will depend on a combination of factors.

1. The Cash Flow of the Business

One of the most important considerations is how much cash the target company generates.

Acquisition debt ultimately needs to be repaid from business cash flow.

You therefore need to consider:

  • Historic cash generation
  • Working capital requirements
  • Tax
  • Capital expenditure
  • Existing borrowing
  • Debt repayments
  • Owner replacement costs
  • Other future investment requirements

A company with strong and predictable cash generation may be able to support more acquisition debt than a business with volatile cash flow.

2. EBITDA

Funders often use EBITDA as part of their assessment of how much debt a business can support.

They may consider:

  • Reported EBITDA
  • Adjusted EBITDA
  • Maintainable EBITDA
  • Historic trends
  • Cash conversion
  • Future forecasts

A business generating £500,000 of sustainable EBITDA may support a different funding structure from one generating £150,000.

However, EBITDA should never be viewed in isolation.

A capital-intensive business may generate strong EBITDA while requiring substantial ongoing expenditure on machinery or equipment.

3. Capital Expenditure

You need to understand how much money the company will require after completion.

For example, the business may need to:

  • Replace machinery
  • Upgrade technology
  • Refurbish premises
  • Purchase vehicles
  • Expand capacity

If you use every available pound to fund the purchase price, the company may have insufficient capital remaining for these investments.

Your acquisition structure should therefore consider both the cost of buying the business and the cost of owning it afterwards.

4. The Seller's Expectations

The seller's objectives can significantly influence how a deal is structured.

Some owners may want:

  • As much cash as possible at completion
  • A clean exit
  • No ongoing financial exposure

Others may be willing to accept:

  • Deferred consideration
  • Seller finance
  • An earn-out
  • A minority retained shareholding
  • A phased exit

Understanding the seller's priorities can create more options for structuring the transaction.

5. The Buyer's Personal Capital

Most acquisition funding structures require the buyer to contribute some personal capital.

This demonstrates commitment and reduces the amount of external finance required.

The buyer's contribution may come from:

  • Cash savings
  • Investment proceeds
  • Sale of another business
  • Other available personal funds

The amount of personal capital available can influence the size of business you are realistically able to acquire.

6. The Amount a Lender Will Provide

A lender will assess the target business before deciding how much acquisition finance it is prepared to offer.

That assessment may consider:

  • EBITDA
  • Cash flow
  • Balance sheet strength
  • Assets
  • Sector
  • Customer concentration
  • Management
  • Seller involvement
  • Buyer experience

Some lenders may assess borrowing capacity using an EBITDA multiple.

However, this should be treated as an indicative approach rather than a guaranteed formula.

7. How Much Is Paid at Completion?

The percentage of the purchase price paid on completion can have a major effect on whether the acquisition is fundable.

For example, paying 60% of the purchase price at completion creates a lower initial funding requirement than paying 80%.

The balance may then be paid through:

  • Deferred consideration
  • Seller finance
  • Earn-out
  • Future purchase of retained shares

This is sometimes referred to as the day-one payment or completion payment.

8. How Long the Business Has Been for Sale

The seller's negotiating position may change over time.

An owner who has recently brought the business to market may expect a high percentage of the price at completion.

An owner who has been trying to sell for a long period may become more flexible around:

  • Deferred consideration
  • Seller finance
  • Retained equity
  • Deal structure

This does not mean you should automatically expect favourable terms, but seller motivation can influence what is commercially possible.

9. Whether There Are Competing Buyers

Competition matters.

If several credible buyers are bidding for the same company, the seller may favour:

  • Higher completion payments
  • Fewer conditions
  • Less deferred consideration
  • Faster completion
  • Greater funding certainty

A highly structured offer may be less competitive if another buyer can offer more cash at completion.

 

Main Ways to Structure a Business Acquisition

A transaction may use one or several of the following methods.

Cash at Completion

This is the amount paid to the seller when the transaction legally completes.

Sellers generally prefer a higher completion payment because it gives them greater certainty.

For the buyer, however, a high completion payment increases the amount of capital that must be raised upfront.

Acquisition Finance

Debt can be used to fund part of the acquisition.

This might include:

  • Bank lending
  • Specialist acquisition finance
  • Asset-backed lending
  • Invoice finance
  • Other business lending

The appropriate type of finance depends on the target business and the transaction.

Deferred Consideration

Deferred consideration is part of the agreed purchase price that is paid after completion.

For example:

  • £700,000 at completion
  • £150,000 after 12 months
  • £150,000 after 24 months

This reduces the amount the buyer needs to fund on day one.

However, those later payments still need to be affordable.

Seller Finance

Seller finance occurs when the seller effectively lends part of the purchase price to the buyer.

The buyer then repays that amount over an agreed period.

This can help bridge a funding gap where external lenders will not finance the entire completion payment.

Earn-Out

An earn-out makes part of the purchase price dependent on future business performance.

For example, the seller might receive an additional payment if the company achieves a specified EBITDA level.

Earn-outs can help bridge a valuation gap where the buyer and seller have different views about future performance.

However, the calculation needs to be clearly defined.

Retained Equity

The seller may keep some shares in the company after completion.

For example, the buyer could acquire 80% of the business while the seller retains 20%.

This can:

  • Reduce the initial purchase price
  • Reduce the buyer's funding requirement
  • Keep the seller invested in future performance
  • Support continuity after completion

The parties should agree how and when the seller's remaining shares may eventually be purchased.

Investor Equity

An external investor may contribute capital in return for a shareholding.

This might involve:

  • Private equity
  • A family office
  • High net worth investors
  • Other private capital

Using equity reduces the amount of debt required but means the buyer shares ownership with another investor.

 

Worked Example: Structuring a £1 Million Business Acquisition

Assume a target business has:

  • Valuation: £1 million
  • Maintainable EBITDA: £250,000
  • Valuation multiple: 4x EBITDA
  • Buyer personal capital: £100,000
  • Estimated deal costs: £120,000

The funding requirement changes significantly depending on how much of the purchase price is paid at completion.

Scenario 1: 60% Paid at Completion

Purchase price paid at completion:

£1,000,000 × 60% = £600,000

Add transaction costs:

£600,000 + £120,000 = £720,000

Deduct buyer capital:

£720,000 - £100,000 = £620,000

The buyer therefore needs approximately:

£620,000 of additional funding

The remaining £400,000 of the purchase price would need to be structured separately.

This might involve:

  • Deferred consideration
  • Seller finance
  • Earn-out
  • Retained equity


Scenario 2: 70% Paid at Completion

Completion payment:

£1,000,000 × 70% = £700,000

Add transaction costs:

£700,000 + £120,000 = £820,000

Deduct buyer capital:

£820,000 - £100,000 = £720,000

The buyer therefore needs approximately:

£720,000 of additional funding

This is £100,000 more than the 60% completion structure.

 

How the Funding Multiple Changes the Deal

Now assume a lender assesses funding using a multiple of maintainable EBITDA.

Funding at 2x EBITDA

Maintainable EBITDA:

£250,000

2x EBITDA:

£500,000

If the buyer requires £620,000 under the 60% completion scenario:

Funding shortfall = £120,000

If the buyer requires £720,000 under the 70% scenario:

Funding shortfall = £220,000

Funding at 2.5x EBITDA

2.5 × £250,000 EBITDA:

£625,000

Under the 60% completion scenario, the lender could theoretically cover the £620,000 funding requirement.

Under the 70% scenario:

£720,000 - £625,000 = £95,000 shortfall

This demonstrates how relatively small changes to the completion payment or funding capacity can materially affect whether a transaction is achievable.

 

Comparing the Example Structures

  60% completion 70% completion
Business valuation £1,000,000 £1,000,000
Completion payment £600,000 £700,000
Deal costs £120,000 £120,000
Total initial requirement £720,000 £820,000
Buyer capital (£100,000) (£100,000)
External funding required £620,000 £720,000
Funding at 2x EBITDA £500,000 £500,000
Shortfall £120,000 £220,000
Funding at 2.5x EBITDA £625,000 £625,000
Shortfall £0* £95,000

*Illustrative only. Actual funding availability will depend on lender assessment, affordability, deal structure and other transaction factors.

 

How Can You Bridge a Funding Shortfall?

A funding shortfall does not necessarily mean the acquisition cannot proceed.

Potential solutions include:

Increase Your Personal Capital

Introducing additional buyer capital reduces reliance on external funding.

Reduce the Completion Payment

The seller may agree to receive more of the purchase price after completion.

Use Deferred Consideration

Part of the price can be paid from future cash flow.

Negotiate Seller Finance

The seller may agree to finance part of the acquisition price.

Buy Less Than 100%

Acquiring a majority stake rather than the entire company can reduce the amount required at completion.

Bring in an Investor

An external investor can provide additional equity capital.

Reconsider the Valuation

If the purchase price cannot be supported by the target company's earnings and cash flow, the valuation may simply be too high for the proposed structure.

 

Do You Need to Buy 100% of the Business?

No.

A buyer may acquire less than 100% of the shares.

For example, purchasing 80% rather than 100% can reduce the initial transaction value and funding requirement.

This may suit a seller who:

  • Wants to remain involved
  • Wants to retain some future upside
  • Prefers a phased retirement
  • Is willing to support the transition

The buyer and seller should agree how the remaining shares will eventually be dealt with.

 

How Much Should You Pay at Completion?

There is no standard percentage that applies to every acquisition.

The appropriate completion payment depends on:

  • Seller expectations
  • Funding availability
  • Business cash flow
  • Deal risk
  • Buyer capital
  • Competition from other buyers
  • Deferred payment terms

The important point is to avoid agreeing a completion payment that creates an unsustainable funding requirement.

 

Do Not Use All Available Cash to Buy the Business

One of the biggest mistakes a buyer can make is focusing entirely on completing the acquisition while ignoring what happens the following day.

The business still needs enough capital to:

  • Pay employees
  • Pay suppliers
  • Carry stock
  • Fund customer payment terms
  • Invest in growth
  • Replace equipment
  • Deal with unexpected problems

Your deal structure should therefore preserve sufficient liquidity after completion.

 

Stress-Test the Deal Before You Commit

Before making a final offer, test different assumptions.

For example:

  • What happens if EBITDA falls by 10%?
  • What if interest costs increase?
  • What if a major customer leaves?
  • What if working capital requirements rise?
  • What if capital expenditure is higher than expected?
  • What if deferred payments become due during a difficult trading period?

A structure that only works when everything goes perfectly may be too aggressive.

 

Get Professional Advice on the Structure

Deal structure can have significant financial, tax and legal consequences.

Depending on the transaction, you may need input from:

  • Corporate finance advisers
  • M&A accountants
  • Acquisition finance specialists
  • Solicitors
  • Tax advisers

The objective is not simply to find enough money to complete.

It is to create a transaction that remains sustainable after you become the owner.

 

Structure a Deal That Works Beyond Completion

The best acquisition structure is not simply the one that gets the deal completed.

It is the one that allows the business to continue operating, investing and meeting its obligations after ownership changes hands.

Frequently Asked Questions

How do you structure a deal to buy a business?

A business acquisition can be structured using a combination of buyer capital, acquisition finance, cash at completion, deferred consideration, seller finance, earn-outs and retained equity.

What is a typical business acquisition deal structure?

There is no single typical structure. Many SME acquisitions combine personal capital from the buyer with external debt and some form of deferred or seller-funded consideration.

Do I need to pay the full purchase price at completion?

No. The seller may agree to receive part of the purchase price after completion through deferred consideration, seller finance or an earn-out.

What is a completion payment?

The completion payment is the amount paid to the seller when ownership of the business transfers to the buyer.

What is deferred consideration?

Deferred consideration is part of the agreed purchase price that is paid after completion according to an agreed timetable.

What is seller finance?

Seller finance is where the seller effectively finances part of the purchase price and receives payment from the buyer over time.

What is an earn-out?

An earn-out is a payment that only becomes due if the business achieves agreed future performance targets.

Can I buy less than 100% of a business?

Yes. A buyer can acquire a majority or minority shareholding rather than purchasing the entire company.

How much personal capital do I need to buy a business?

There is no universal percentage. The amount will depend on the purchase price, lender requirements, cash flow of the business and wider deal structure.

How much will a lender provide for a business acquisition?

This depends on the target company's profitability, cash flow, balance sheet, sector, assets and other risk factors. Some lenders may assess capacity using an EBITDA multiple, but funding is not determined by EBITDA alone.

What happens if there is a funding shortfall?

Possible solutions include increasing buyer capital, reducing the completion payment, using deferred consideration, negotiating seller finance, bringing in an investor or purchasing less than 100% of the company.

Should I use all my available cash to buy a business?

Usually, you should consider retaining sufficient liquidity for working capital, transaction costs, unexpected expenditure and post-acquisition investment.
