A business plan serves as a roadmap for your business and should explain how you plan to achieve your vision. It can help you to have a better understanding of your business goals and identify potential roadblocks. It can be a crucial part of securing finance and helping your business to stay on track.

What are the six main purposes of a business plan?

There are many reasons why it pays to write a business plan - and all of them ultimately boost your chances of establishing a thriving business.Ìý 

We’ve outlined the main purposes of a business plan below:

1. Proving your business idea is viable

Creating a business plan helps you establish whether your business idea could really work. As an entrepreneur, you need to consider estimated startup costs and include a profit and loss forecast and a cash flow forecast.Ìý

Taking these steps can help to reassure anyone looking at your plan that you’re serious about your business and have crunched the numbers to make sure it can succeed.

2. Outlining your company’s strategy and goals

It’s not always easy to establish goals and targets once your business is up and running. But writing them into a business plan means you know what you’re aiming for in two, three or five years' time. This can help you to stay focused and on track.

3. Securing finance

Having a business plan can increase your chances of securing finance from investors. Potential investors want to see how you plan to use their money and how it could help your business grow.

They also need to see that you’ve researched the industry and your target audience, as well as developed a strong product or service. The last thing they want to do is invest in a business that’s destined to fail.

4. Identifying problems and reducing risks

Carrying out market research and analysing competitors in your business plan should help you identify any potential issues early on, enabling you to prepare your response in advance.Ìý

5. Attracting talent 

A well-crafted business plan can help you attract skilled staff by outlining your company’s goals and values. Showing how you plan to grow the business can instil confidence in your team and give them job security.

6. Sharing your vision

Lastly, a business plan enables you to share your vision for your company with investors and staff so that everyone is on the same page. This can help everyone work towards the same goals and make decisions that align with them.Ìý 

Key elements of a business plan

There are several key business plan sections that you need to include in your business plan. We’ve outlined these below:

  • Executive summary: A succinct overview of the business plan

  • Company description: An explanation of your business and what it does

  • Market analysis: Research on your industry and target market

  • Competitive analysis: Research about your competitors and their strengths and weaknesses

  • Products or services: A description of what you’re selling and how it stands out from the competition

  • Organisational structure and management: An overview of the company’s structure and the key players involved

Traditional vs lean startup business plans

A traditional business plan is the most common type of business plan and is often 30 to 40 pages long. It goes into plenty of detail about your business and involves extensive research and planning, following the format mentioned above.

By contrast, a lean startup business plan requires less time to put together. It’s not as in-depth and has a high-level focus. It tends to only be one or two pages long and covers:

  • A description of the problem your startup is solving

  • Your target audience

  • How your product or service solves the customer’s problem

  • How your product or service stands out from the competition 

  • The cost of producing the product or launching the service

The idea behind a lean startup business plan is to get your product or service to market as quickly as possible. This can be beneficial if your business idea is time-sensitive or if it’s a competitive industry. You can also ditch your plan more easily if it doesn’t work.

On the other hand, if you have a unique idea or you’re launching larger and more ambitious products, a traditional business plan is likely to be a safer bet. Lenders and investors usually ask to see a traditional business plan before offering funding.Ìý
