How to write an executive summary for your business plan

Writing an executive summary can reveal how clearly you understand your business.

Can you explain who your customers are, why they would choose you and how the business will make money? Can you show what you have learned so far and what needs to happen next?

If those answers are difficult to put into words, that is useful information. It gives you somewhere to focus your thinking.

I started my first company without a business plan. Having since built businesses and worked with other founders, I see the value in making your assumptions explicit. A plan gives you something to question, test and change as you learn.

Your executive summary brings that thinking together in a short, readable account of the business.

What is an executive summary?

An executive summary is a concise overview of your business plan. It explains the opportunity, how you intend to pursue it and what supports your approach.

Someone reading it should understand the essentials without needing to work through the full plan first.

The emphasis depends on its purpose. An investor will need to understand the funding opportunity.

Your leadership team may need clarity about priorities, resources and the decisions ahead.

Be clear about who you are writing for before deciding what to include.

Should you write it first or last?

I find it useful to start with a rough version. It exposes gaps and gives you a starting point for the rest of your planning.

Expect it to change.

Customer research might alter your target market. Your cost estimates might change your hiring plans. Testing your sales approach might show that growth will take longer than you expected.

Once you have worked through the detail, return to the summary and make sure it reflects what you now know. It should agree with the rest of your plan, including the figures.

1. Explain what your business does

Start with a straightforward description of your business, the customers it serves and the value it provides.

Avoid opening with a broad mission statement that leaves the reader guessing what you actually sell.

A useful starting point is:

We help [specific customer] achieve [valuable outcome] through [product or service].

Then explain the problem or need behind that outcome. What happens today? Why does it matter enough for someone to spend money or change how they work?

If this is difficult to express, revisit your value proposition before adding more detail.

2. Describe the customer and market opportunity

Be specific about the customers you intend to serve first.

“Small businesses” or “anyone who wants to be healthier” leaves too much unanswered. Which businesses or people have the strongest need? Where are they? Who makes the buying decision?

Summarise the opportunity using evidence you can explain. That might include customer research, an estimate of the number of relevant buyers or early sales experience.

Distinguish the wider market from the customers you can realistically reach. A large market does not, on its own, show that your business has a route into it.

Keep detailed calculations and research in the market opportunity section of your plan.

3. Explain why customers would choose you

Describe the alternatives customers already have, including doing nothing or managing the problem themselves.

Then explain why your approach would be worth choosing.

Perhaps you serve a group whose needs are poorly met. Perhaps you reduce a costly delay or make a difficult task easier. Whatever the difference, connect it to something the customer values.

Avoid relying on claims such as “innovative”, “high quality” or “excellent service” without explaining what they mean in practice.

You do not have to claim that nobody has ever done anything similar. You do need a credible reason for customers to choose your business.

4. Show what you have learned or achieved

Give the reader a clear picture of the business today.

Depending on your stage, relevant evidence might include:

• Customer interviews that changed your understanding of the problem.

• A prototype tested with intended users.

• Paying customers and repeat purchases.

• Revenue, retention or product usage.

• A working sales channel or partnership.

Be precise about what each result demonstrates. Positive feedback is useful, but it is different from a commitment to buy. A successful trial is encouraging, but it does not automatically show that you can sell repeatedly.

If you are still testing the idea, say so. Explain the main uncertainty and how you intend to investigate it.

5. Outline how you will earn revenue and win customers

Explain who pays, what they pay for and how you charge.

Then summarise how customers will find you and how a purchase happens. You might sell directly, work through partners or use a service that customers can buy themselves.

Focus on the approach you intend to prioritise. A list of every possible marketing channel gives little sense of what you will actually do.

Make clear which parts are already working and which are assumptions you still need to test.

6. Introduce the team and the capabilities you need

Explain why the people involved are suited to the work ahead.

Include relevant experience and responsibilities rather than a list of impressive job titles. Show how the team’s capabilities connect to the business you are building.

Be honest about gaps. If the plan depends on hiring someone, developing a skill or bringing in outside support, make that visible.

For founders leading a growing business, this also means considering your own role. What will you continue to own and what will need to move to someone else?

7. Summarise the finances and funding needs

Include the financial information that helps the reader understand your position and plans.

Depending on the stage and purpose of the document, this could include current revenue, major costs, cash needs and a short forecast.

Label actual results and forecasts clearly. Explain the important assumptions behind the numbers rather than presenting growth as a certainty.

If you are seeking funding, state how much you need, what it will support and the milestones you intend to reach. If you plan to grow through customer revenue, explain that approach.

The summary should give a clear overview. The supporting financial model is where the detail belongs.

8. Set out the next milestones

Finish with what needs to happen next.

Choose milestones that show meaningful progress. That might mean testing whether customers will pay, improving retention, establishing a repeatable sales process or adding a capability the business needs.

Where useful, include timing and responsibility.

Also identify the assumptions that could change your plan. Doing so helps you decide what to watch and when to reconsider your approach.

If the summary is intended to support a specific decision, make that decision clear. What are you asking the reader to consider or agree?

Keep it short enough to use

Aim for one or two pages as a starting point, unless the intended reader asks for a different format.

Use short paragraphs and clear headings. Explain unfamiliar terms and remove detail that belongs elsewhere in the plan.

A practical check is to give the summary to someone who does not know the business well. Ask them to explain back:

• Who the customer is and why they would buy.

• How the business earns money.

• What evidence supports the plan.

• What needs to happen next.

Their answers will tell you more than asking whether they liked it.

Keep the summary connected to the business

An executive summary is worth revisiting when your plans or circumstances change.

Use it with your team to check whether you still agree on the customer, priorities and resources. If the business is moving in a different direction, update the plan and discuss why.

The value comes from the thinking and conversations it supports.

If working through your plan has raised bigger questions about focus, growth or your role as a founder, explore working with me through founder coaching and mentoring.
