A strong business plan does more than describe an idea. It explains how the business can work in practice.
What should be in a business plan and how do you know if you've included the right information?
Most templates cover familiar sections: market research, products or services, marketing, operations and financial forecasts.
But completing a template doesn't automatically create a credible business plan.
What matters is the thinking behind each section. A strong plan explains why the opportunity is commercially viable, what evidence supports your assumptions and how you intend to deliver the results.
Here are seven essentials every founder should get right.
1. A clear business proposition
Explain what your business does, who it serves and why customers would choose it.
A common mistake is describing a product in detail without explaining the problem it solves.
Your proposition should answer three questions:
Who is your target customer?
What problem are you solving?
Why would customers choose you over existing alternatives?
Avoid generic claims such as innovative or high quality unless you can explain what makes your offer genuinely different.
The test: Can someone understand your business opportunity in a few sentences?
2. Evidence of customer demand
A growing market doesn't automatically mean customers will buy your product.
You need evidence of demand for your specific offer, at your intended price.
This might come from customer interviews, competitor research, pilot sales, pre-orders or testing an early version of your product.
Remember that positive feedback isn't the same as purchasing intent.
The test: What evidence suggests customers will actually pay?
3. Market and competitor understanding
A credible plan demonstrates that you understand your market, competitors and positioning.
Look beyond market size. Consider what alternatives customers already use, how competitors are priced and where opportunities exist.
Your competitors aren't necessarily businesses selling identical products. Customers might solve the same problem differently or decide not to purchase at all.
The test: Why would customers choose your business over their current solution?
4. A realistic revenue and pricing model
Explain how your business will generate revenue and whether that revenue can support its costs.
Consider your pricing, expected sales, delivery costs and profit margins.
For example, a consultancy charging £1,000 per project must account for more than the time spent delivering the work. Marketing, software, administration and periods without clients all affect profitability.
A product business must also consider manufacturing, packaging, fulfilment and returns.
The test: Does your business model make financial sense after accounting for the real costs?
5. A practical marketing and sales strategy
Identifying your target audience is only the beginning.
Your plan should explain how you'll reach potential customers and convert interest into sales.
We'll promote the business on social media isn't a strategy.
Which channels will you use? Why are they appropriate for your audience? What resources will you need, and how will your activities support your sales targets?
The test: Can you explain how customers will find you and what it might cost to acquire them?
6. The resources and capabilities to deliver
Even a promising business idea needs the right resources to succeed.
Identify the skills, suppliers, technology, processes and people required to operate your business.
Consider whether your current capabilities can support your expected sales and growth.
For example, increasing orders creates little value if you cannot fulfil them efficiently or maintain quality.
The test: Can your business realistically deliver what you're promising?
7. Financial forecasts, risks and assumptions
Your financial forecasts should connect your commercial strategy to realistic numbers.
Depending on your business, this may include start-up costs, sales forecasts, profit and loss projections, cash flow and funding requirements.
Pay particular attention to cash flow. A business can generate sales and still struggle if expenses must be paid before customers pay.
Most importantly, explain your assumptions.
What needs to happen to achieve your sales targets? What if revenue is lower than expected or costs increase?
The test: Can you justify your numbers and explain what happens if your assumptions prove wrong?
What about the executive summary?
A formal business plan usually begins with an executive summary, although it's often easier to write it last.
It should briefly explain the business opportunity, target market, commercial model, strategic priorities and key financial information.
If you're seeking funding, include the amount required and how it will be used.
Think of it as an introduction to your business case, not a replacement for the evidence behind it.
What makes a business plan credible?
A credible business plan doesn't need to be unnecessarily complicated. It needs to be clear, consistent and supported by evidence.
The strongest plans connect the different elements of the business.
Your customer research should inform your proposition. Your positioning should influence pricing. Your marketing strategy should support sales forecasts. Your operational capabilities should match expected growth.
For example, forecasting hundreds of new customers without a realistic acquisition strategy raises an obvious question: where will those customers come from?
A good business plan tells one coherent commercial story and explains the assumptions behind it.
Final thoughts
A business plan shouldn't simply describe an attractive future. It should help you evaluate an opportunity, make informed decisions and identify what needs to happen next.
You may not have every answer when you begin. The important thing is to distinguish what you know from what you assume, identify the gaps and test your thinking as the business develops.

Ultimately, the quality of a business plan comes from the commercial thinking behind it, not the number of pages it contains.
