Buying a business: the process and how to pay for it

Buying an existing business can be quicker than starting one, but it comes with checks, costs and legal steps. Here is the process, the difference between buying shares and assets, and the ways buyers pay for it.

The short answer

Buying a business means buying either a company’s shares or its assets and trade. The process runs from valuation and due diligence through negotiation to completion. Buyers usually pay from their own funds plus borrowing or deferred payments to the seller, and any lending is subject to status and lender criteria.

What does buying a business mean?

Buying a business means acquiring either the company that owns it or the assets and trade it uses. You take over customers, contracts, staff and equipment, and, depending on the structure, some of the history that comes with them.

Buyers choose it to skip the early years of a start-up, to enter a market with an existing customer base or to grow by taking on a competitor. It carries its own risks, because you pay for what is there today and inherit what the seller did not tell you.

Should you buy shares or assets?

It depends on how much of the business’s history you want to take on: a share purchase brings the whole company, while an asset purchase lets you choose what you buy. The table sets out the difference.

Share purchase compared with asset purchase
PointShare purchaseAsset purchase
What you buyThe company itself, through its sharesSelected assets and trade, such as equipment, stock and customer lists
LiabilitiesThe company keeps them, so you take them on with itYou generally take only what you agree to buy
ContractsStay with the companyMay need to be transferred or renegotiated
DutyUsually 0.5% of the price on sharesStamp Duty Land Tax if property is included; check goodwill and other assets with an accountant
StaffThe employer stays the sameTUPE may apply, because the employer changes

Because the legal and tax consequences differ, ask a solicitor and an accountant which structure fits your deal before you make an offer.

What are the steps to buy a business?

The steps run from research to completion, and finance should be discussed early, not left to the end.

  1. Decide what you are looking for: sector, size, location and how involved you want to be.
  2. Find a business and ask for its accounts, key contracts and the reason the owner is selling.
  3. Value it and agree a price in principle.
  4. Carry out due diligence, checking the figures and the paperwork behind them.
  5. Arrange the finance and agree the terms of the sale agreement with your solicitor.
  6. Complete the purchase, pay any duty and update the records at Companies House and with HMRC.

A purchase of a smaller business can be simpler than one involving many staff, property or a complex group, but speed depends on the parties and on the findings of due diligence, so do not plan around a fixed timetable.

How do you value and check a business before buying?

You value and check a business by testing the seller’s figures against evidence, not by taking the asking price at face value. Our guide to how to value a business covers the methods; due diligence is where you confirm that the numbers are real.

  • Accounts and management figures: are the profits consistent, and do they reconcile to bank statements and tax returns?
  • Customers and contracts: how much comes from one customer, and can the contracts be transferred?
  • Staff: who is essential, what are their terms and who may leave when the owner does?
  • Liabilities: debts, leases, disputes, outstanding tax and any security already held over the assets.
  • Premises and equipment: who owns them, and what condition are they in?

Ask your accountant to review the figures, such as EBITDA and the balance sheet, and your solicitor to review the contracts.

What does buying a business cost beyond the price?

Beyond the price you will pay duty, professional fees and the cost of running the business while it settles in. Plan for these in the funding, because they come due around completion.

  • Duty on shares: usually 0.5% of the price. If you use a stock transfer form, Stamp Duty applies when the price is over £1,000 and is due within 30 days of the form being signed and dated.
  • Duty on property: Stamp Duty Land Tax applies in England and Northern Ireland, with a £150,000 threshold for non-residential property, and the return is due within 14 days of completion. Our guide to stamp duty on commercial property has more.
  • Advisers: solicitors, accountants and any specialist surveys or reports.
  • Working capital: money for wages, suppliers and tax in the first months.

The duty rates and thresholds above are those GOV.UK shows today. Rates change, so confirm them with an accountant before you rely on them. Capzy does not give tax, legal or accounting advice.

What happens to staff and company records?

Where TUPE applies, employees’ jobs and terms usually transfer to the new employer. GOV.UK says the new employer takes over contracts, including terms, holiday entitlement and continuity of employment, and that employers must inform and consult representatives before the transfer.

TUPE applies to a business transfer where the identity of the employer changes, so it is more likely in an asset purchase than where you buy the company’s shares. If you buy shares and gain more than 25% of the shares or voting rights, you will usually be a person with significant control, and the company must tell Companies House of the change within 14 days of confirming it.

How do you pay for a business?

Most buyers pay with a mix of their own money, borrowing and, sometimes, payments deferred to the seller. Which mix fits depends on the price, the assets and the cash flow of the business.

Ways buyers pay for a business
MethodHow it worksWhere it tends to fit
Own fundsSavings or other money you put inPart of almost every deal
Term loanA loan repaid in instalmentsThe balance of the price where cash flow supports repayments
Asset financeBorrowing secured on equipment or vehicles in the dealBusinesses with significant equipment
Commercial mortgageA loan secured on propertyDeals that include premises
Seller financeThe seller is paid part of the price laterClosing a gap between what lenders will advance and the price

Lenders will look at the target’s cash flow as well as at you, and may ask for a personal guarantee. Our guide to acquisition finance explains how lenders approach the borrowing side in more detail.

What is the difference between buying a business and a franchise?

Buying an independent business gives you full control but no ready-made system, while a franchise gives you a brand and a method in return for fees and rules set by the franchisor. Both need finance, and both need the same checks on the numbers and the contract.

If a franchise is what you are considering, read our guide to franchise finance. If you are a manager buying the company you work for, see the guide to a management buyout.

What are the risks and common mistakes?

The biggest risks are overpaying, missing a hidden liability and borrowing more than the business can support. These usually come from rushing or from relying on the seller’s numbers alone.

Borrowing is your responsibility

If the business earns less than you expected, the repayments are still due. Test your plan against a weaker year, and read any guarantee carefully before you sign it.

  • Skipping or shortening due diligence.
  • Forgetting duty, fees and working capital in the budget.
  • Not checking whether key contracts and licences transfer.
  • Depending on the seller’s relationships with no handover plan.
