A business plan is a written document that describes what your business does, how it makes money, who it serves, and where it is going. It gives you a structured roadmap to follow and is often required when seeking a bank loan, attracting investors, or applying for a grant. Understanding how to write a business plan is a fundamental skill for any entrepreneur looking to turn a vision into a scalable reality.
The good news is you do not need to be a finance expert to write one. Most business plans follow a consistent structure, and once you understand what goes in each section, the writing becomes a matter of filling in what you already know about your business. This guide walks you through every step.

Step 1: Write the Executive Summary Last
Even though the executive summary appears first in a business plan, write it last. It is meant to summarise everything in the plan, and you cannot summarise what you have not yet written.
Keep it to one page. Cover who you are, what problem you solve, who your customers are, and what you are asking for (if anything). Think of it as the elevator pitch for the written version of your business.
Step 2: Describe Your Company
This section answers the basic questions: What does your business do? When was it founded? Where is it located? What is your legal structure (sole trader, LLC, limited company)?
Include your mission statement here. A good mission statement is one or two sentences that describe the purpose of the business, not the product. For example: ‘We help small businesses manage their finances without needing an accountant’ is a mission. ‘We make accounting software’ is a description.
Step 3: Conduct a Market Analysis
This is where most people get stuck, but it does not need to be complicated. You need to demonstrate that a real market exists for what you are selling.
- Define your target market: age, location, income level, buying behaviour
- Estimate the market size: how many potential customers are there?
- Identify your top 3-5 competitors and note their strengths and weaknesses
- Explain what makes you different and why customers would choose you
Step 4: Outline Your Team
Investors and lenders often say they back the team, not the idea. This section should give confidence that the right people are in place to execute the plan.
List key team members, their roles, and relevant experience. If you are a solo founder, highlight what you bring and acknowledge where you plan to hire or outsource.
Step 5: Detail Your Products or Services
Explain clearly what you sell, how it works, and what it costs to produce or deliver. Focus on the value it creates for the customer, not just its features. If you have intellectual property, patents, or proprietary processes, mention them here.

Step 7: Build Your Financial Projections
This is the section that tends to intimidate people the most, but you only need to cover three things for a basic plan:
Revenue forecast: Project monthly sales for at least 12 months. Be realistic and show your working.
Expense forecast: List all costs: rent, salaries, software, marketing, supplies. Separate fixed from variable costs.
Break-even analysis: Calculate the point where your revenue covers all expenses. Investors want to know how long it takes to get there.
Common Mistakes to Avoid
- Overestimating revenue in year one without evidence to support it
- Ignoring the competition or claiming there is no competition
- Writing for investors when the plan is for your own use, and vice versa
- Using technical jargon that confuses rather than impresses
- Leaving the financials too vague or making them impossibly optimistic

The One-Page Business Plan Option
If you are in the early stages and just need to clarify your thinking, a one-page version can be surprisingly effective. Organise it around these five questions:
Final Thought
The real value of a business plan is not the document itself. It is the thinking you do while writing it. Going through the process forces you to confront assumptions, spot gaps, and make decisions before they cost you money. Revisit your plan every six months and update it as your business grows.
