Selling my business: a complete guide

What business owners need to know about preparing, valuing and successfully selling a business.

Key takeaways

  • Start earlier than you think you need to. Preparing your business for a sale can take three to five years, so it pays to plan well before you want to step away. There is more to it than getting the paperwork ready: building a strong management team, reducing reliance on key customers and demonstrating consistent performance all take time. Starting early gives you the opportunity to address weaknesses before buyers raise them and greater flexibility to sell when the timing is right.
  • Value is not just a multiple of profit. Buyers will look at the quality and sustainability of earnings, future growth, cash flow and how dependent the business is on particular people or relationships. The headline valuation is only part of the picture: cash, debt, working capital adjustments and payments linked to future performance can all affect what you receive and when.
  • The right buyer depends on the outcome you want. A trade sale, management buyout and private equity investment can offer different combinations of price, continuity and future involvement. Be clear about whether you want a clean break, a phased exit or a continuing stake in the business. Compare buyers on their plans, funding certainty and proposed terms, as well as the amount they offer.
  • Think about tax and your personal plans before the deal structure takes shape. What you sell, how you are paid and whether you retain shares or an ongoing role can affect your tax position and the proceeds available to you. Consider the sale alongside your longer-term financial, family and succession plans. Taking advice before commercial terms are fixed gives you more room to compare options and understand the implications.
  • A well-run process creates choice. Clear sale materials, carefully targeted buyer approaches and well-organised information help you compare credible offers and maintain momentum. Preparing for due diligence and addressing known issues early can reduce surprises that weaken confidence or reopen negotiations. Throughout the process, keep the business performing and assess the whole deal, not just the highest headline price.

How does selling a business work?

Put simply, selling your business means agreeing to transfer either the shares in the company or some or all of its assets. In practice, the route you choose can change the price, the tax position, what stays with you, and what the buyer takes on. It can also affect how involved you need to be after completion.

The process usually starts by understanding what you want to achieve from the sale. From there, your adviser will help prepare the business and its story, identify potential buyers and manage offers. Once a preferred buyer is chosen, they will test what they have been told through due diligence before the final terms are agreed.

The headline price matters, but so do the details and the certainty behind it: how much is paid on day one, what is deferred and what depends on future performance.

The business sale process, step by step

1. Start with the outcome you want

Think beyond the sale price. When would you like to step back? Do you want a clean break or an ongoing role? What matters for employees, customers, the brand and other shareholders?

2. Look at the business as a buyer would

Test the quality of the financial information, the systems, the strength of the management team, key contracts, tax affairs, working capital and the risks that could prompt difficult questions later.

3. Build a realistic view of value and your options

Understand the likely valuation range, the buyers who may see the strongest fit and the deal structures that could support your objectives.

4. Tell a clear, evidence-based story

Sale materials should explain what makes the business attractive, where growth will come from and why the opportunity is credible. The figures and the narrative need to support each other.

5. Approach the market carefully

Potential buyers should be contacted discreetly and given detailed information only once the right confidentiality protections are in place.

6. Compare the whole offer

The highest headline price is not always the best deal. Consider funding certainty, conditions, timing, deferred payments, future involvement and the buyer’s plans for the business.

7. Choose who to progress with

Once you select a preferred buyer, the main terms are usually set out and a period of exclusivity may follow. This is the point at which certainty and momentum become particularly important.

8. Be ready for due diligence

The buyer will test financial, tax, legal, commercial and operational information. Well-organised evidence and clear answers can help maintain confidence and keep the process moving.

9. Work through the detail

The final agreement will cover price adjustments, warranties, indemnities and any deferred or performance-related payments. These points can materially change the risk and value of the deal.

10. Plan for completion and what follows

Ownership transfers, payments are made in line with the agreement, and any handover begins. Your personal, financial and practical plans should be ready too.

How much is my business worth?

When owners start thinking about a sale, the first question is often: what is my business worth? It sounds like a numbers question, but the answer is shaped by much more than a formula. Value depends on the quality of the business, what the market will support and what a particular buyer believes they can do with it.

Buyers will look at sustainable earnings and cash flow, but they will also test the story behind the numbers. How visible is future revenue? Is growth repeatable? Does the business rely too heavily on one owner, customer or supplier? Is there a management team capable of delivering the plan? Strong answers can create confidence. Weak or unproven assumptions tend to reduce what a buyer is prepared to pay.

It is also important to separate the headline valuation from what the deal is really worth to you. Cash, debt, working capital adjustments, deferred payments and earn-outs can all change the amount received at completion and the certainty attached to the rest. A sensible valuation gives you a realistic range and helps you judge the whole offer, not just the biggest number on the page.

Who might buy your business?

Trade sale

A trade buyer is usually another business in your sector or an adjacent market. They may be willing to pay for something they cannot easily build themselves: your customers, people, technology, products, capabilities or geographic reach. That strategic value can make a trade sale attractive, although conversations with competitors need to be handled carefully and confidentially.

Management buyout

A management buyout can offer continuity. The people who already know the business take ownership, often with support from external debt or equity funding. For some owners, that continuity matters as much as price. The trade-off is that the management team’s funding capacity may influence how much can be paid upfront and how the rest of the deal is structured.

Private equity

Private equity can be a good fit where there is a strong management team and a clear plan for further growth. It may allow an owner to realise some value now while retaining a stake in the next stage of the business. That can create a second opportunity to benefit, but it also means staying exposed to future performance and being clear about your role after the investment.

How much tax will I pay when I sell my business?

Tax is one of the questions owners understandably focus on, but there is no single answer. What you pay will depend on what is being sold, how the consideration is structured, your own circumstances and the rules in force at the time. A share sale can produce a different result from an asset sale, while earn-outs, deferred payments, retained shares and any ongoing role can add further complexity.

For family businesses, the tax considerations may go beyond the sale itself. If you are weighing up a sale against gifting shares or passing the business to the next generation, inheritance tax and the availability of Business Relief may influence both the timing and structure of your plans. These decisions are best considered early and alongside your wider succession, estate and personal financial planning.

The important point is to look at tax before the shape of the deal hardens. By then, the room to change course may be limited. Early advice can help you compare options, understand any reliefs that may be available and see what the headline offer could mean in terms of net proceeds.

Getting your business ready to sell

Preparation is not about making the business look perfect. It is about understanding where a buyer is likely to challenge the story and dealing with those points before they can weaken confidence or value. The earlier you start, the more of the outcome remains within your control.

  • Make the business less dependent on you. A buyer will want to see a management team that can lead, make decisions and deliver the plan without relying on one person. Documenting key processes can help turn personal knowledge into business capability.
  • Make the numbers easy to trust. Accurate accounts, useful management information and credible forecasts help buyers understand performance. Be ready to explain adjustments to earnings and show the evidence behind them.
  • Show that performance can last. Buyers will look beyond a strong recent period. Help them understand historic trends, the quality of revenue, future opportunities and how current trading compares with the plan.
  • Deal with concentration risk. Heavy reliance on one customer, supplier or key employee can affect value and certainty. Where possible, diversify relationships, strengthen contracts and put sensible retention plans in place.
  • Understand cash and working capital. Know what the business needs to operate normally and identify unusual, debt-like or non-operating balances before they become points of negotiation.
  • Tidy up the details. Company records, intellectual property, property documents, employment terms, commercial agreements, tax compliance and regulatory matters should all stand up to scrutiny.
  • Prepare for the questions you would ask. Organise the evidence, challenge your own assumptions and address known issues early. A surprise during due diligence can weaken trust as well as price.

How long does it take to sell a business?

There is no standard timetable. A straightforward sale may complete within several months, while a more complex transaction can take longer. The quality of the information, the buyer’s funding, regulatory approvals, due diligence findings and the pace of negotiation all play a part.

The more useful question is often not how quickly you can sell, but how much time you need to prepare for sale. Building a management team, reducing concentration risks or creating a stronger track record cannot always be done in a few weeks. Starting before you feel ready to sell gives you the option to act when the timing is right, rather than being forced to accept the position you are in.

How to get you and your shareholders on the same page

A good exit plan starts with clarity. What does a successful outcome look like for you and for any other shareholders? How much certainty do you need? When would you be prepared to sell, and what would make you walk away? Price will be part of the answer, but so might legacy, employees, family, culture and your own role after the deal.

These priorities are not always the same for every shareholder. One person may want certainty now; another may want to hold out for maximum value. Neither position is necessarily wrong, but unspoken differences tend to surface at the worst possible time, when a buyer is already at the table.

Our North Star programme helps you have these conversations early. We bring shareholders together to agree on what they want, look at what could affect the value of the business and set out the steps needed for a sale or family succession. It means clearer decisions and fewer surprises later.

Why use us for your exit planning

Every exit is different, because every owner starts from a different place and wants a different outcome. Our deal advisory, tax and financial planning teams can help you turn those priorities into a practical plan, from the first conversation about readiness through to the transaction and what comes after it.

We can help you:

  • build a realistic view of what the business may be worth and where focused preparation could strengthen that value;
  • identify the buyers most likely to see a strong fit, drawing on our UK and international network;
  • shape a clear, credible story supported by the right financial information;
  • run a competitive and confidential process without losing sight of day-to-day trading;
  • get ahead of due diligence, coordinate advisers and deal with issues before they slow momentum;
  • assess offers on their full terms and support negotiations on the commercial and financial detail;
  • understand the tax implications, available reliefs, alternative structures, clearances and reporting requirements; and
  • connect the transaction with your longer-term personal and financial plans.

Frequently asked questions

How much tax will I pay if I sell my business?

There is no single figure that applies to every sale. The answer depends on what is being sold, how and when the consideration is paid, your circumstances and the tax rules at the time. The best point to take advice is before the commercial terms are fixed, while there is still room to compare structures and understand the likely net proceeds.

How much is my business worth?

A valuation is a reasoned range, not a promise. Buyers will consider maintainable earnings, cash flow, assets and market evidence, then make their own judgement about growth, recurring revenue, management strength and risk. The terms of the offer can be just as important as the headline number.

What’s the best way to sell my business?

The best route is the one that fits what you want from the exit. A trade buyer may see strategic value, a management buyout may offer continuity, and private equity may support a phased exit and further growth. Compare the price with the certainty, timing, future role and compromises attached to each option.

How long does it take to sell a business?

A sale often takes several months, but preparation may need to begin much earlier. Incomplete information, buyer funding, regulatory approvals, due diligence findings and difficult negotiations can all extend the timetable. Starting early gives you more choice and reduces the pressure to solve important issues once the deal is already moving.
