Business Plan: How to Write One Step by Step

A business plan is a structured document that describes your business, its goals, strategy and financial plan. Whether you're just starting out, applying for a bank loan, or seeking a grant, a well-prepared business plan is essential.

Many first-time entrepreneurs and OSVČ see writing a business plan as a pointless formality. The truth is that the process of creating one forces you to think through every aspect of your business, identify weaknesses, and set realistic expectations. A business plan isn't just a document for your bank or investor — it's primarily a tool for yourself.

In this article, we'll walk you through a complete business plan structure, provide practical tips for each section, and explain when and why you'll need one.

When You Need a Business Plan

Applying for a Bank Loan

Banks require a business plan as a standard attachment to a business loan application. They use it to assess the viability of your business and your ability to repay the loan. The better your plan is prepared, the higher your chances of getting the loan approved on favorable terms.

Applying for a Grant or Subsidy

Most grant programs — whether from national sources or EU funds — require a business plan or an abbreviated version of one. You can find information about current grant programs for entrepreneurs on the website of the Ministry of Industry and Trade or on the CzechInvest portal.

Finding an Investor

If you're looking for an investor (business angel, venture capital fund), a business plan is your primary tool for presenting your business idea. Investors use it to assess the potential return on their investment.

Your Own Planning and Management

Even without external pressure, a business plan is a valuable tool for:

• Clarifying your vision and strategy
• Identifying risks and opportunities
• Planning cash flows
• Tracking progress and achieving goals
• Communicating with business partners

Complete Business Plan Structure

A professional business plan follows a clearly defined structure. Below are the recommended sections with a detailed description of what each one should contain.

1. Title Page

The title page is the first impression your plan makes. It should include:

• Company name / self-employed individual's name
• Logo (if you have one)
• Document title (Business Plan)
• Date of preparation
• Document version
• Author's contact details
• Confidentiality notice (if relevant)

2. Executive Summary

The executive summary is the most important part of a business plan. Although it appears at the beginning, it's usually written last, as it summarizes the entire document.

What it should include:

• Brief description of the business (what you do)

4. Market Analysis

How to work with your SWOT analysis:

• Use strengths to capitalize on opportunities
• Address weaknesses in your development plan
• Incorporate opportunities into your marketing strategy
• Prepare contingency plans for identified threats

6. Marketing Strategy

Your marketing strategy describes how you will attract and retain customers. It is one of the key sections of a business plan.

Marketing mix (4P/7P):

Key processes:

8. Financial Plan

The financial plan is the core of a business plan and the section most carefully evaluated by banks and investors. It must be realistic, backed by data, and consistent with the rest of the plan.

Start-up costs (for new businesses):

• Own funds vs. external funding
• Repayment terms and schedule

9. Risk Analysis

Every business plan should include an identification of the main risks and a plan for mitigating them.

Risk categories:

• Market risks – declining demand, entry of a new competitor, changing customer preferences
• Financial risks – insufficient cash flow, currency risk, unpaid receivables
• Operational risks – loss of a key employee, technology failure, supplier issues

Practical Tips for Writing a Business Plan

What to Do

• Be specific – include numbers, deadlines and names, not vague statements
• Be realistic – overly optimistic projections undermine credibility
• Back up your claims with data – statistics, research, and references from reliable sources
• Write clearly – avoid overly technical jargon, especially if a banker will be reading the plan
• Update regularly – a business plan is a living document, not a one-off exercise
• Seek advice – consult a mentor, accountant or industry expert

What Not to Do

• Don't copy someone else's plan – every business is unique
• Don't ignore the competition – claiming "we have no competitors" is a red flag for investors
• Don't underestimate costs – include hidden and unexpected costs in your plan
• Don't overestimate revenue – a conservative estimate with a pleasant surprise is better
• Don't overlook cash flow – a business can be profitable on paper and still go bankrupt due to a lack of cash
• Don't let your plan go stale – review and update it regularly

Business Plan for Self-Employed Individuals – Simplified Version

If you're self-employed and don't need a plan for a bank or investor, you can work with a simplified version. It should include at least:

Where to Find Data for Your Business Plan

A quality business plan must be backed by data. Here are sources where you can find relevant information:

• Czech Statistical Office (ČSÚ) – demographic data, economic statistics, consumer spending
• Ministry of Industry and Trade – mpo.gov.cz – data on the business environment, industry statistics
• CzechInvest – information on investment incentives and grants
• Public Register (justice.cz) – financial statements of competitors (for companies)
• Industry associations and unions – sector-specific data, trends, benchmarks
• Google Trends – search trend data for key terms
• Social media – research into the preferences and behavior of your target audience

Frequently Asked Questions (FAQ)

How long should a business plan be?

For a loan or investment application, typically 20–40 pages. For personal use as a self-employed individual, 5–15 pages is sufficient. Length isn't what matters most — it's the quality of the content. Be specific and to the point.

How much does it cost to have a business plan prepared professionally?

If you hire a professional, the cost typically ranges from 10,000 to 50,000 CZK or more, depending on the complexity of the business. However, we recommend writing at least the first version yourself — nobody knows your business better than you do. A professional can then help with the final polish.

How often should a business plan be updated?

At least once a year, or whenever there is a significant change in circumstances (new product, entry into a new market, legislative changes, economic crisis). Update your financial projections quarterly.

Do I need a business plan to register as self-employed?

No — the trade licensing office does not require one. However, it is strongly recommended to have at least a basic plan for your own purposes.

How do I write a financial plan when I'm just starting out and have no historical data?

Use estimates based on market research, competitor pricing and realistic assumptions. Create three scenarios (optimistic, realistic, pessimistic). Clearly describe the assumptions you're working from. Bankers and investors value transparency far more than unrealistically high figures.

Can I use a business plan template?

Templates are a good starting point, but you should never simply fill one in without thinking it through. Every business is unique and your plan must reflect your specific situation, market and strategy. Templates are most commonly available on the websites of business incubators, banks, or the BusinessInfo.cz portal.

What if the bank rejects my business plan?

Find out the reason for the rejection and revise your plan accordingly. Common reasons for rejection include: unrealistic financial projections, insufficient market analysis, a weak competitive advantage, and inadequate loan collateral. Also consider alternative sources of financing (leasing, factoring, crowdfunding, grants).

Does a self-employed person need a business plan?

The law does not require one. In practice, however, you will need one if you are applying for a loan, a grant, or looking for an investor. Even without these needs, a business plan is a valuable tool for the strategic management of your business.

Summary

A business plan is an indispensable document for anyone who is serious about their business. Whether you need it for a bank, an investor, or your own strategic planning, the investment of time and effort in putting one together will pay off many times over.

Key takeaways:

• Start with market and competitive analysis
• The financial plan must be realistic and backed by data
• A SWOT analysis will reveal your strengths and weaknesses
