How to Write a Business Plan

Learning how to write a business plan is one of the most important steps you’ll take as an entrepreneur. Whether you’re launching a side hustle, applying for funding, or growing a team, a well-crafted plan provides structure, direction, and clarity. Professionals can write the plan for you, but knowing what goes in a plan and the basics of writing one can help you ensure that the document truly represents your idea or enterprise.

In 2025, investors and support agencies expect more than just buzzwords. They want thoughtful analysis, realistic forecasts, and clearly defined goals. This guide will take you through every step, with examples and insights to help you write a business plan that works.

Why Every Startup Needs a Business Plan

A business plan isn’t just a document for investors. It’s a decision-making tool that helps you define your vision, refine your strategy, and stay accountable as you grow.

In today’s climate, startups face economic uncertainty, AI-driven change, and increasing competition. A business plan gives you a way to test ideas on paper before spending money. It also helps you explain your business to funders, co-founders, and future team members.

Even if you never share your plan, the process of writing one will help you think clearly. It’s also recommended to learn how to write a business plan early on, even if you’re not yet seeking investment or support, as this will help guide your business implementation from the get-go.

What to Include in Your Business Plan

Every business plan you write should be tailored to your goals, so a funding plan may look different to one for an in-house strategy. Understanding how to write up a business plan helps ensure it meets your objectives while aligning with what funders want to see.

Executive Summary

This is the first section of your business plan, but it should be written last. It briefly summarises your business idea, key objectives, market opportunity, and financial highlights. Keep it to one page and use it to make a strong first impression. Most investors won’t read further if this part doesn’t resonate, so leaving it till the end ensures you’ve thought through the entire document before writing this page.

Business Overview

Describe your business in simple terms, including your mission, core activities, and whether you’ll operate as a sole trader, company, or another legal structure. Explain how your business generates income and what market needs it addresses. Be clear about your value proposition by focusing on what makes your offer different or better than what already exists.

Market Research

This section demonstrates your understanding of the market you plan to enter. Include competitor analysis, customer behaviour, and any relevant trends that affect demand. Use statistics and data to back up your claims, and explain how your business will fit into the current landscape.

Products or Services

Explain what you’re offering and the benefits it delivers to your target customers. Highlight any unique features, pricing models, or intellectual property that adds value. If you have multiple offerings, clarify how they relate to each other and contribute to revenue.

Marketing Plan

Detail how you’ll attract customers and keep them coming back. Outline your brand messaging, marketing channels (e.g., social media, SEO, email), and promotional tactics. Include pricing strategy and customer acquisition costs where possible, especially if you’re pitching to investors.

Operations Plan

Show how your business will run on a day-to-day basis. Include suppliers, equipment, software, delivery methods, and any logistics that keep the business functioning. If you need licenses, permits, or insurance, explain how and when you’ll obtain them.

Team

If you have co-founders or staff, describe their roles and relevant experience. Investors and lenders often back people as much as they do ideas, so highlight team strengths. If you’re a solo founder, explain how you’ll manage key tasks and where you plan to outsource.

Financial Forecasts

Lay out your expected revenue, expenses, and profit in detail for the first 12 months at least, though ideally include a three to five-year overview as well. Include cash flow projections, break-even analysis, and assumptions behind your numbers. Visual aids like charts or tables help make this section easier to understand.

Funding Needs

Specify how much funding you need, what it will be used for, and the benefits it will bring to your business. Break the amount into categories, such as marketing, hiring, and equipment, to show you’ve thought it through. Be transparent about what’s negotiable and how you plan to repay or reward funders.

Exit or Growth Strategy

Explain your long-term vision for scaling or exiting the business. This could include expansion plans, acquisition targets, or a timeline for investor return. Even if you’re not aiming to sell, funders want to know your plan for sustainable growth and profitability.

How to Write a Business Plan: Step-by-Step

Writing a business plan can feel overwhelming at first, especially if you’re doing it alone. But when broken down into clear steps, the process becomes far more manageable. Here’s how to take your idea and turn it into a structured, useful business plan.

1. Start with Notes, Not a Blank Page

Before you open a document or download a template, start by jotting down your thoughts. Make rough notes about what you want to do, who your ideal customer is, and how you’ll make money. Use bullet points, voice memos, or a business model canvas, just as long as you get your ideas out of your head and onto paper.

Once you have these raw notes, group them into broad themes, such as Market, Money, and Operations. This will help you identify which parts are strong and where you need to do more research. Don’t worry about structure or spelling at this stage; after all, you’re aiming for clarity, not polish.

2. Do Real Research and Record Your Sources

Next, start building out your knowledge. Look into your industry trends, pricing models, competitors, and customer habits. Use government reports, surveys, business directories, or even Reddit and forums to gather insights.

Take notes as you go and copy the links or sources. This information will feed your market analysis, pricing strategy, and sales forecasts. If you can, include statistics that show your business is solving a real need, since this builds credibility from the start.

3. Create a Simple Structure

Use a clear and common structure that makes your plan easy to navigate. A basic structure could include: Executive Summary, Business Description, Market Research, Product/Service, Marketing Plan, Operations, Team, Financial Forecasts, Funding Needs, and Growth Strategy.

Using the right format is essential when you’re learning how to write a business plan for a loan or for pitching to potential partners.

You can write these headings into a document straight away as they’ll act as signposts and make the writing feel more achievable. If you’re using a business plan template or automated tool, customise the layout so it fits your idea and goals.

4. Write One Section at a Time

Focus on writing one section at a time, starting with the easiest one. For most entrepreneurs, this is often the product/service or team section. Write in a clear, straightforward tone, as if you’re explaining your business to someone intelligent but unfamiliar with your industry.

Don’t worry about perfect grammar yet. Aim to answer key questions under each heading, such as:

• Who is my customer?
• What is my pricing?
• How much money do I need to launch?

There will be time for polishing your text later. At this stage, focus on writing a business plan that makes sense.

5. Back Up Your Claims with Logic or Numbers

Avoid vague promises such as this product will go viral or customers will love this. Instead, back up every important claim with numbers, comparisons, or logic. For example, explain why your pricing is competitive, how many potential customers are in your area, or how similar businesses are performing.

If you’re making financial forecasts, use conservative estimates based on realistic growth. Include assumptions, such as we expect 5% conversion from website visitors based on industry averages, so readers understand how you arrived at your figures.

6. Leave the Executive Summary Until Last

Your executive summary should sum up the entire plan, so write it after everything else is done. It should cover your business idea, main offering, market opportunity, goals, and a snapshot of your financials or funding needs.

This is usually the first thing people read, so make it concise, persuasive, and focused. A single page is ideal, and it helps to think of it as the pitch version of your full plan.

7. Ask for Feedback From Non-Experts

Once you’ve written your plan, ask someone outside your industry to read it. If they can understand your idea, how it makes money, and why it’s viable, then you’re on the right track. Their questions will help you identify unclear sections or areas you need to strengthen.

You can also test it with a mentor, advisor, or trusted business contact. If you’re applying for funding, consider booking a short call with a local enterprise office or support agency to review it before submitting.

8. Edit for Clarity, Then for Style

Take a break before editing, ideally a day or two, so you can return with fresh eyes. In your first round of edits, focus on clarity: cut repetition, fix contradictions, and ensure each section flows into the next.

Once that’s done, improve the tone and presentation. Use short paragraphs, headings, and white space to improve readability. If needed, create a separate business plan presentation using your main points for pitching or meetings.

Common Business Plan Writing Mistakes to Avoid

Even the best business ideas can fall flat if the plan behind them is unclear or unrealistic. Below are common mistakes that can weaken your business plan, and practical ways to avoid them:

• Being Too Vague About Your Offer: If your product or service isn’t clearly defined, readers will struggle to understand what you’re actually selling. Be specific about what you offer, who it’s for, and why it matters. Use examples or short use cases to make it concrete.
• Overestimating Revenue or Underestimating Costs: Many founders present overly optimistic financials without enough evidence or context. Base your projections on conservative estimates and industry benchmarks. Clearly state your assumptions for credibility.
• Skipping Proper Market Research: Without data on your industry and competitors, your plan may come across as wishful thinking. Use reputable sources, customer surveys, and competitor analysis to demonstrate demand and prove you understand your market.
• Using Generic or Overused Phrases: Phrases like world-class service or revolutionary idea add fluff but no substance. Use plain language and real-world proof, such as testimonials, pilot data, or comparisons, to build trust.
• Missing a Clear Customer Profile: If your plan targets everyone, it effectively targets no one. Create one or two clear customer personas with specific traits, problems, and buying behaviours. Tailor your plan to speak to them.
• Forgetting to Include a Marketing Plan: Some plans focus heavily on the product but fail to explain how it will be seen or sold. Include your promotional tactics, marketing channels, and customer acquisition strategy — even if it’s low-cost or local.
• Failing to Show How the Business Will Operate: A great idea needs systems to support it, such as suppliers. Explain your operational model, technology, key suppliers, and the day-to-day setup, especially if you’re applying for funding.
• No Exit or Growth Strategy
  Plans that end at year one can look short-sighted or incomplete. Include a basic three- to five-year vision. If you’re unsure how to make a three-year business plan, start by mapping milestones year by year and build from there. Whether it’s scaling, franchising, or preparing for sale, show that you’ve thought beyond the launch.

Business Plans That Impress in 2025

A business plan that worked five years ago may no longer meet the expectations of today’s funders, mentors, or partners. In 2025, standout plans show more than just financial ambition, they reflect strategic thinking, digital awareness, and adaptability. If you’re short on time or want expert input, you can always turn to a trusted business plan writing service to get it done professionally.

Here are the key qualities that make a business plan stand out this year.

Sustainability and Social Impact

Increasingly, banks, grant bodies, and investors favour businesses that consider their environmental and social footprint. Show how your business reduces waste, supports the local economy, or promotes ethical practices. Even small actions, such as using green packaging or hiring locally, can make a difference in perception and eligibility for support.

Digital Maturity

Being online isn’t enough anymore for most startups and ambitious businesses. Funders want to see businesses that use digital tools smartly to stay competitive. Mention how you’ll use software to manage operations, connect with customers, or streamline delivery. Even free tools like Canva, Trello, or Xero can demonstrate your readiness to run a lean and modern business.

Clear Scalability

Plans that scale well without needing massive resources tend to attract more interest. Explain how your model grows by detailing whether you will add new locations, replicate a process, or increase automation. Show that you’ve thought about growth in phases, with realistic milestones.

Realistic Risk Management

Acknowledging business risks and mitigating them adds credibility. Include key risk assessments covering market shifts, supplier issues, or regulatory changes. Briefly explain what you’d do in each case, such as alternate suppliers, price adjustments, or policy updates. Remember to highlight how likely each risk is to happen.

AI and Automation Awareness

AI isn’t just for tech startups. In 2025, even small businesses are expected to know how it affects their industry. Mention tools you might use, such as AI chatbots, forecasting tools, or content generators, and how they’ll reduce costs or improve service. If you’re not using AI, it helps to explain why, especially if your sector is being disrupted by this technology.

Customisation for the Reader

Writing a business plan that’s generic or right off a template won’t cut it if you’re applying for a grant or pitching an investor. Tailor your language, format, and emphasis to the person or organisation reviewing it. It’s also important to highlight the sections they care most about, such as social impact for grant bodies, or ROI for investors.

Strong Visuals and Clean Design

You don’t need to be a designer to deliver well-developed business plans, but presentation matters. A cluttered or outdated plan can make a bad first impression. Use headings, white space, charts, and tables to make the plan easy to navigate. Tools like Canva, Google Docs, or Notion can help you format your plan professionally with minimal effort.

Future-Ready Forecasts

Plans with only short-term thinking can seem underdeveloped. A forward-looking plan shows leadership, so include a basic three-year or five-year summary with goals, milestones, and key challenges.

A three-year plan would suffice in most cases, but creating a 5 year business plan can be useful to get funding for an enterprise that won’t turn a profit in the first years of operation. You don’t need precise figures, but show you’ve thought about what comes next and how you’ll adapt.

Final Thoughts

Learning how to write a business plan is more than just a cut-and-paste process; it’s a chance to practise strategic thinking, staying focused, and communicating your vision with clarity. Whether you’re aiming for funding, testing a new idea, or setting long-term goals, taking the time to write a well-structured plan can move your business forward faster and with fewer surprises. Start small, be honest with your assumptions, and build from there.
