Business Plan Basics for New Founders

TL;DR: A business plan does not need to be a 50-page document — a clear one-page plan covering your market, revenue model, costs, and milestones is enough to start.

What You Need to Know

Many new founders treat the business plan as something you write for the bank or an investor, then never look at again. This is a missed opportunity. A well-made business plan is a thinking tool — it forces you to test your assumptions, identify where you could fail, and create a baseline against which you can measure your actual performance.

The requirement for a business plan varies by context. For registration purposes, no country requires a business plan. For a business bank account, most banks want to see one. For external investment, a more detailed plan is expected. For your own sanity and accountability, even a simple one-page version is valuable.

This guide covers what a business plan should include, how detailed it needs to be at different stages, and country-specific resources that new founders in the UK, France, Sweden, Australia, New Zealand, Canada, and the United States can use.

How It Works: A Practical Overview

What a Business Plan Is (and Is Not)

A business plan is a written document that describes your business — what it does, who it serves, how it makes money, and what it needs to reach its goals. It includes financial projections that test whether the model can work at scale.

A business plan is not:

• A guarantee of success
• A document you write once and put in a drawer
• A creative writing exercise designed to impress investors
• Required to be long or formally formatted

The most useful business plans are living documents that founders refer to regularly, update as circumstances change, and use to hold themselves accountable to their own projections.

The Core Sections Every Business Plan Should Cover

1. Executive Summary

A one-paragraph overview of the business. What does it do? Who does it serve? What is the market opportunity? This section is written last but placed first.

2. Business Description

What is the business? What problem does it solve? What is your product or service? What is your legal structure and country of registration?

3. Market Analysis

Who are your target customers? What is the size of the market you are targeting? Who are your competitors, and what do they do? What is your competitive advantage — why would customers choose you?

Be specific and realistic here. "Our market is everyone who uses the internet" is not a market analysis. "Our market is small accounting firms in the UK with under 10 employees, of which there are approximately 25,000 according to the ICAEW" is a market analysis.

4. Products and Services

Describe your offering in detail. What is included? What is the pricing? What is your cost to deliver? What is your gross margin?

5. Marketing and Sales Strategy

How will customers find you? How will you convert them? What channels will you use (online, word of mouth, direct sales, partnerships)? What is your customer acquisition cost and how does it compare to the customer lifetime value?

6. Operations Plan

How will the business operate day to day? Who will do the work? What suppliers do you depend on? What technology do you use? What are the key operational risks?

7. Management and Team

Who is running the business? What relevant experience do they have? If there are gaps in the team, how will they be filled?

8. Financial Projections

This is where you test whether the business model works. At minimum, include:

• Revenue forecast: Monthly for Year 1, quarterly for Years 2–3. What assumptions drive this?
• Cost forecast: Fixed costs (rent, salaries, software) and variable costs (cost of goods, commissions)
• Profit and loss projection: Revenue minus costs = profit or loss
• Cash flow projection: When does cash come in and go out? Do you ever run out of cash?
• Break-even analysis: At what revenue level do you cover your costs?

The financial projections do not need to be precise — they are projections, not certainties. But they need to be honest. If the numbers only work under wildly optimistic assumptions, the plan is telling you something important.

How Detailed Should It Be?

For personal use (accountability and planning): A one-page plan or a simple spreadsheet is enough. Update it monthly.

For a business bank account: Most banks want to see a short narrative (1–3 pages) plus 12 months of financial projections. Keep it simple and professional.

For a startup loan or grant: Government schemes and loan funds vary in their requirements. Check the specific requirements of the programme. In the UK, for example, Start Up Loans (https://www.startuploans.co.uk) has a specific application process.

For angel investment or venture capital: Investors see hundreds of plans. They want a clear problem, a compelling solution, an evidence-based market size, and realistic financial projections showing the path to strong growth. A 15–20 page plan plus a financial model is typical at this stage.

Common Formats

One-page business plan / Business Model Canvas: Excellent for early-stage thinking and internal use. The Business Model Canvas (https://www.strategyzer.com/canvas/business-model-canvas) is a widely used template.

Traditional business plan (10–30 pages): Required by most banks and investors. Includes all sections above in full.

Pitch deck (10–15 slides): Used for presenting to investors. Usually accompanied by a separate financial model.

Country-by-Country Comparison

Most national business development agencies in these countries offer free business plan templates that are designed for their local banking and regulatory environment.

Common Mistakes to Avoid

1. Projecting hockey-stick growth with no justification. Most business plans that fail validation show enormous growth in Year 2 or Year 3 with no explanation of where that growth will come from. Investors and bank managers have seen this pattern thousands of times. If your projections show sudden acceleration, explain precisely why and what evidence supports the assumption.
2. Ignoring competition. Writing that "there is no direct competition" almost always signals a lack of market research, not a genuine market gap. Every business competes with something — even if it is the customer's current manual process or an adjacent product. Acknowledge competition and explain your differentiation clearly.
3. Confusing profit with cash. A business can be profitable on paper and still run out of cash if customers pay slowly or if there are large upfront costs. Always include a cash flow projection, not just a profit and loss statement.
4. Writing it and forgetting it. Review your plan against actual results every quarter. Understanding the gap between your plan and reality is where real learning happens.
5. Overclaiming in the management section. Do not pad CVs or overstate experience. Sophisticated investors will check. Gaps or early-stage experience honestly presented are far less damaging than exaggerations that are discovered.

Frequently Asked Questions

Q: How long should my business plan be?

It depends on the purpose. For personal use, one page is sufficient. For a bank account, one to three pages plus financial projections. For investors, ten to twenty pages plus a financial model. There is no benefit to length beyond what is needed to make the case clearly and completely.

Q: Do I need a financial advisor to write my financial projections?

Not necessarily, but a qualified accountant's input significantly improves the credibility and accuracy of your projections. They can also identify tax implications and cost structures you may have overlooked. For complex businesses or investment-focused plans, engaging an accountant is strongly recommended.

Q: Can I use an AI tool to write my business plan?

AI tools can help with structure and drafting, but the underlying analysis — market research, competitive assessment, financial modelling — must reflect genuine research and your own judgment. A plan written entirely by AI without this foundation will not withstand scrutiny from a bank manager or investor.
