What is a business plan?

A business plan is a document that outlines your business strategy, goals, and path to profitability. It explains what your business does, who it serves, and how it will make money.

A strong business plan helps you secure funding, guide decision-making, and stay focused as your business grows. Research shows that more than three-quarters of business angels require business plans before considering investments.

Why do you need a business plan?

A business plan turns your ideas into a clear, actionable strategy. Even if you know your market and have the right skills, writing it down helps you spot gaps, stay focused, and communicate your vision to others.

Here's why a business plan matters:

• Clarify your ideas: Writing forces structure, and your strategy becomes clearer on paper than in your head.
• Identify problems early: Gaps in your thinking become obvious when you write them down.
• Get useful feedback: A written plan lets trusted advisors review and improve your approach.
• Prove you're serious: Banks, investors, and accountants expect a formal document before they commit. One study found that 99% of surveyed VCs read or at least skim business plans.
• Stay focused as you grow: A plan keeps you on track when day-to-day work becomes a distraction.

What goes into a business plan?

A complete business plan covers 10 essential sections. Each section answers a specific question investors and lenders want to know.

Here's what you'll include:

• Executive summary: A brief overview of your business and goals
• Customer identification: Who will buy your product or service
• Target audience analysis: Demographics, location, and behaviours of your ideal customers
• Growth opportunities: How your business can scale over time
• Competitive analysis: Who your competitors are and how you'll differentiate
• Financial plan: Startup costs, revenue projections, and profitability
• Marketing plan: How you'll attract and retain customers
• Operations plan: Day-to-day processes and workflows
• Team structure: Key hires and advisors
• Format and length: Keeping your plan focused and readable

Each component is explained step by step.

How to write your business plan

Follow these 10 steps to create a business plan that's clear, complete, and ready to share with investors or lenders.

1. Start with the executive summary

The executive summary is a brief overview of your entire business plan. It describes your company, product or service, and core mission in a few sentences.

Think of it as an elevator pitch. Keep it short, memorable, and focused on what makes your business worth attention. You can read more about how to create the executive summary in the guide What is an Executive Summary in a Business Plan?

2. Identify your customers

Define exactly who will buy your product or service. Investors ask this question early, so have a clear answer ready.

Consider the following:

• Identify your customer type: Decide whether you're selling to consumers or businesses. If you're selling to businesses, specify who makes the buying decision.
• Understand purchase patterns: Determine whether you'll have repeat clients or one-time buyers.
• Validate with real conversations: Talk to potential customers before finalising your plan.

3. Analyse your target audience

Target audience analysis helps you understand exactly who your customers are. Go beyond assumptions and define your audience using these factors:

• Demographics: Age, gender, income level, and social status
• Firmographics: Company size, revenue, and industry (for B2B businesses)
• Location: Specific regions, cities, or countries you'll serve
• Profession: Job roles or industries you're targeting
• Interests: Shared hobbies, behaviours, or community affiliations

4. Outline your growth opportunities

Growth opportunities are the ways your business can expand over time. Even if you're starting small, map out how you could scale.

Consider questions like:

• How will customers find you online?
• Will you need salespeople, or will your marketing drive conversions?
• Could you open a physical location as revenue grows?

Document these possibilities now so you're ready to act when the time comes.

5. Research your competition

Competitive analysis shows investors you understand your market. List both existing and potential competitors, and explain how you'll stand out.

Address these questions:

• Direct competitors: Who sells the same products or services?
• Indirect competitors: Whose offerings overlap with yours?
• Barriers to entry: What makes it hard for new competitors to enter your market?
• Unique selling proposition (USP): What makes you different from everyone else?

Your USP is critical. Explain how you'll differentiate on price, service, quality, or value.

6. Create a simple financial plan

A financial plan outlines the costs of starting and running your business. According to the U.S. Small Business Administration, you should provide a prospective financial outlook for the next five years, with the first year broken down into quarterly or monthly projections. Include these key figures:

• Product costs: Expenses to make or purchase inventory
• Labour and materials: Manufacturing, raw materials, and production wages
• Employee costs: Salaries, benefits, and contractor fees
• Marketing and distribution: Advertising, shipping, and sales expenses
• Overheads: Rent, utilities, insurance, and other fixed or variable costs

Accounting software like Xero can help you build a draft financial model. Talk to your accountant or bookkeeper for guidance on projections.

7. Develop your marketing plan

A marketing plan explains how you'll attract and retain customers. Use the five Ps framework to structure your approach:

• Pricing: How will you price your product or service competitively?
• Positioning: Where does your offering fit in the market?
• Promotion: Which channels will you use to reach customers?
• Profit: What margin do you expect per sale?
• Place: Where will customers buy from you?

8. Plan your operations

An operations plan describes how your business runs day to day. Set your vision aside and focus on the practical tasks required to deliver your product or service.

Cover key areas like:

• Production: Manufacturing, packaging, and quality control
• Sales: Order processing, customer acquisition, and account management
• Customer service: Support channels, response times, and issue resolution
• Administration: Invoicing, record-keeping, and compliance

9. Build your team

Your team section shows investors you have the right people to execute your plan. Outline who you need to hire and how their skills complement yours.

Consider these questions:

• What roles are essential to launch and grow?
• How will you attract talent to a new business?
• Who will advise and mentor you as challenges arise?

Strong advisors and a capable team build investor confidence.

10. Keep it simple and focused

Simplicity makes your business plan effective. People don't read long, complex documents, so keep your plan brief and focused. For instance, business plan consultants suggest that 15–25 pages of text is the sweet spot.

Aim for a core document of just a few pages. If you find yourself overwriting, stop, take a break, and edit ruthlessly. You can use the free business plan template to stay on track.

Make your business plan work for you

Build your plan around your strengths while being honest about areas for improvement. A realistic plan is more likely to convince investors you're serious.

Keep these principles in mind:

• Review regularly: Update your plan at least once a year as your business evolves. Many successful businesses follow a review cycle of 45 days to six months to adapt more quickly to market changes.
• Seek feedback: Ask advisors, mentors, and trusted colleagues to review your plan.
• Stay flexible: Your plan is a roadmap, not a fixed contract. Adjust as needed.

FAQs on business plans

Here are answers to common questions about creating and using business plans.

How long should my business plan be?

According to experts, the body of a business plan should be between 15 and 25 pages, with an appendix for detailed financial projections. However, the core sections can often fit in just a few pages, so focus on clarity over length.

Do I need different business plans for different audiences?

Yes. Tailor your plan based on who's reading it. Investors focus on growth potential and returns, while banks prioritise cash flow and repayment ability.

What's the difference between a business plan and a business proposal?

A business plan outlines your overall strategy and operations. A business proposal is a pitch to sell a specific product or service to a prospective customer.

How often should I update my business plan?

Review your plan at least once a year. Update it whenever your market, goals, or business model changes significantly.

Can I write a business plan if I don't have financial projections yet?

You can start without detailed projections, but include estimates based on market research. Refine your numbers as you gather more data. An accountant or bookkeeper can help you build realistic forecasts.
