A practical ten-step guide to writing a clear, credible business plan, from the executive summary to the financial plan, with a section-by-section template and a final checklist before you share it.

Samer Choucair, investment entrepreneur

Many founders write a business plan exactly once: when a bank, investor, or funding program asks for it. They fill in a template, add optimistic numbers, send a forty-page document, and never open it again. The result convinces nobody, and it does nothing to help the founder run the business.

A strong business plan is the opposite. It is a thinking tool before it is a document. It forces you to answer the hard questions before the market asks them for you: Who exactly is your customer? Why will they choose you? How much money do you need, and for how long? When will you become profitable? That is why learning how to write a business plan properly is one of the most valuable skills for anyone working out how to become an entrepreneur in a serious, sustainable way.

This business plan guide, part of the Entrepreneurial Mindset series on the Samer Choucair platform, explains what a business plan is and which format fits your stage, walks through ten practical business plan steps, provides a template for structuring each section, covers considerations for the Saudi and Gulf markets, and highlights the mistakes that weaken a plan in the eyes of investors and lenders.

Key Takeaways

Definition: A business plan is a document that explains your business idea, target market, revenue model, execution plan, and financial needs and projections, to guide decisions and persuade funders and partners.
Validate before you write: Test your idea with real customers first. A plan built on untested assumptions only looks convincing on paper.
Choose the right format: Use a detailed plan for banks and investors, and a lean plan or one-page canvas for early stages and internal use.
Numbers are the core: Realistic financials, including a conservative scenario, break-even point, and cash flow, are what funders scrutinize most.
A living document: A good business plan is reviewed and updated every quarter, because the business and the market keep changing.

What Is a Business Plan?

Definition

A business plan is a written document that explains what a business will do, for whom, how it will make money, what resources it needs, and how it will measure success. It typically combines a description of the idea, analysis of the market and competitors, marketing and operational plans, the management structure, and financial projections and funding requirements.

Why you need a business plan

A business plan serves three main purposes, and knowing which matters most to you shapes how you write it:

A thinking tool: it exposes gaps in the idea and untested assumptions before you spend money on them.
A funding tool: banks, investors, and funding programs usually require one to assess viability and risk.
A management tool: it sets priorities, goals, and metrics, and aligns founders, partners, and team members around one direction.

Business plan versus feasibility study

The two are often confused. A feasibility study answers the question “Is this business worth pursuing?” by evaluating the market, costs, and expected return before a decision is made. A business plan answers “How will we build and run this business successfully?” and usually comes after feasibility has been established, often building on its findings.

The plan is a thinking tool first

Its value lies in the questions it forces you to answer, not in the document it produces.

Funders read the numbers

An investor may skim the summary in minutes but will spend far longer on the financials and their assumptions.

Clarity beats length

A clear fifteen-page plan is stronger than fifty pages of generalities.

The plan evolves with the business

What you write today will change after your first hundred customers, and that is healthy.

Types of Business Plans: Which One Do You Need?

No single format suits every business. Choose based on your stage and who will read the plan:

Type	Typical length	Best for	Focus
Traditional business plan	15 to 40 pages	Banks, lenders, and investors	Comprehensive coverage of every section with detailed analysis
Lean business plan	3 to 10 pages	Early stages and initial conversations with partners	The idea, market, revenue model, and key numbers
Business Model Canvas	One page	Fast thinking and testing the model	Nine building blocks showing how the business creates and captures value
Lean Canvas	One page	Startups in the validation stage	Problem, solution, unfair advantage, and key metrics
Internal operating plan	As needed	Management and team	Annual and quarterly goals and responsibilities

The Business Model Canvas was developed by Alexander Osterwalder, and the Lean Canvas was adapted from it by Ash Maurya specifically for startups. Many founders begin with one of these to organize their thinking, then expand into a lean or traditional plan when they need funding.

Before You Start: What You Need to Write a Business Plan

The most common mistake is starting to write before collecting the information the plan requires. A plan does not create knowledge; it organizes it. Before you write, make sure you have:

An idea tested with real potential customers. If you have not done this yet, start by learning how to validate a business idea before anything else.
A clear understanding of the problem you solve and for whom, with early evidence that customers are willing to pay.
Initial research on competitors, their pricing, and their customers’ complaints.
A preliminary estimate of the core costs and resources required. A guide to what you need to start a business can help you list these requirements.
A clear view of who will build the business with you and what each person’s role will be.

Tip

If you find yourself writing “we expect” and “we assume” in most paragraphs, that is a signal you need more market validation before completing the plan.

How to Write a Business Plan: 10 Practical Steps

These business plan steps are ordered in the sequence you should write them, not the order they appear in the final document. The executive summary, for example, appears first but is written last.

Define the purpose and the reader

Ask who the plan is for. A bank cares about repayment capacity and collateral. An investor cares about the size of the opportunity, growth potential, and return. An internal plan focuses on priorities and execution. Each reader needs a different emphasis.

In practice: Write one sentence stating who will read the plan and what decision you want them to make after reading it.

Describe the business and the problem it solves

Explain the idea simply: the problem, who experiences it, and how your business solves it better than current alternatives. Include the vision, mission, legal structure, and current stage of the business.

In practice: Test your description on someone outside your industry. If they cannot understand it in a minute, rewrite it.

Analyze the market and target customer

Define your primary customer segment precisely: who they are, where they are, and what they need and how they buy. Estimate market size logically using credible sources, distinguishing between the total market and the portion you can realistically reach. Avoid huge figures that say nothing about your ability to sell.

In practice: Use data from official or reputable sources, cite the source of every figure, and remove any number you cannot explain.

Study competitors and define your advantage

Analyze direct competitors and indirect alternatives, comparing price, quality, service, and reach. Then state clearly why customers will choose you. Never write “we have no competitors”; it is one of the fastest ways to lose a reader’s confidence.

In practice: Build a simple comparison table between your business and three competitors on the four criteria customers care about most.

Explain the product and the revenue model

Describe what you offer, how it differs, and its development roadmap. Then explain the revenue model: who pays, how much, how, and how often. Most importantly, show the evidence of product-market fit, or your plan to reach it if you are at an early stage.

In practice: Calculate the profit margin per unit sold and confirm it is positive after direct costs.

Build the marketing and sales plan

Explain how you will reach customers and convert them: the channels, the core message, the pricing strategy, the sales process, and an estimated budget. Focus on one or two measurable channels rather than a long list of ideas.

In practice: Estimate the customer acquisition cost for each main channel, even as a rough first figure to refine later.

Design the operations plan

Describe how the business will run day to day: location or platform, suppliers, equipment and technology, production or service delivery, and the implementation timeline. Include the licenses and regulatory requirements relevant to your activity.

In practice: Create a twelve-month timeline with key milestones and the owner of each one.

Present the team and management structure

Funders invest in people as much as ideas. Introduce the founders and their relevant experience, roles and responsibilities, gaps in the team, and how you will fill them. If you have a co-founder, explain ownership and roles clearly, since knowing how to choose the right business partner is something investors examine closely. Show how the team covers the essential skills every entrepreneur needs.

In practice: Link each team member’s experience to a specific part of the execution plan.

Build the financial plan

This is the section funders read most carefully. It typically includes startup costs, monthly operating costs, revenue projections for three to five years, a projected income statement, cash flow, the break-even point, and the amount of funding required and how it will be used. Make every assumption explicit and logical, and present a conservative scenario alongside the base case.

In practice: List the five most important assumptions behind your numbers and explain where each comes from.

Write the executive summary last

The executive summary is the most important page in the plan, and for many readers the only one they will read. Write it last, because it summarizes everything: the problem and solution, market, competitive advantage, revenue model, team, key numbers, and funding request. Keep it to one or two pages.

In practice: Test it: can a busy reader understand the business and decide to keep reading within two minutes?

Editorial Insight

A business plan does not predict the future. It reveals whether you have thought about it seriously.

Business Plan Guide: A Section-by-Section Template

This is the standard order of sections in a traditional business plan, with the question each section should answer:

Section	Question it answers	Suggested length
Executive summary	What is the business, why will it succeed, and what is being requested?	1 to 2 pages
Business description	What is the problem, solution, vision, and legal structure?	1 to 2 pages
Market analysis	Who is the customer, and how big is the opportunity?	2 to 4 pages
Competitive analysis	Who are the competitors, and why will customers choose you?	1 to 2 pages
Product or service	What will you offer, and how will it make money?	1 to 3 pages
Marketing and sales	How will you reach and sell to customers?	2 to 3 pages
Operations plan	How will the business run day to day, and on what timeline?	2 to 3 pages
Team and management	Who will execute, and why are they qualified?	1 to 2 pages
Financial plan	How much do you need, when will you profit, and on what assumptions?	3 to 5 pages
Appendices	What supporting documents back up the plan?	As needed

Writing a business plan with limited resources

If you are starting with limited capital, focus the plan on reaching first revenue at the lowest possible cost, and on stages that can be self-funded before seeking outside investment. A guide on how to start a business with no money offers practical ideas you can build into this part of the plan. If you are still employed, include a realistic transition timeline, informed by the question of whether you should quit your job to start a business.

Writing a Business Plan for Saudi Arabia and the Gulf

If your business will operate in Saudi Arabia, several considerations make the plan more realistic and persuasive to local funders:

Regulatory requirements: in the operations plan, specify your legal structure, commercial registration, activity licenses, and obligations to the Zakat, Tax and Customs Authority (ZATCA), verified with official sources at the time of writing.
Localization: include sector-specific Saudization requirements in your hiring plan, as they directly affect staffing costs.
Support ecosystem: the Small and Medium Enterprises General Authority (Monsha’at) and various funding programs offer resources and guidance for founders. Review the requirements of any program you plan to apply to before drafting.
Alignment with Vision 2030: if your business serves sectors the Vision prioritizes, such as tourism, entertainment, technology, or logistics, explain the connection realistically and without exaggeration.
City-level differences: customer behavior and operating costs can differ between Riyadh, Jeddah, Dammam, and other cities, so define your first market precisely.

Important

Fees, thresholds, and regulatory requirements are updated regularly. Do not include regulatory figures from unofficial sources, and always confirm details with the relevant authority or a qualified advisor.

Common Business Plan Mistakes

Optimistic financials without clear assumptions

Aggressive growth figures with no logic behind them immediately undermine credibility with any experienced funder.

Defining the market too broadly

Saying “everyone in the country is a potential customer” reveals that the business has not yet identified its customer.

Ignoring competitors

Denying that competitors exist suggests either insufficient research or no real market.

Neglecting cash flow

Focusing on projected profit without showing when cash comes in and goes out hides one of the biggest risks for new businesses.

Length over clarity

A long plan full of generalities is weaker than a short, specific one.

Writing it once and forgetting it

A plan that is never reviewed loses its value as a management tool within months.

Frequently Asked Questions About Writing a Business Plan

How do you write a business plan?

To write a business plan, define its purpose and reader, describe the business and the problem it solves, analyze the market and competitors, explain the product and revenue model, set out marketing, operations, and team plans, build the financial plan, and finally write the executive summary that brings everything together.

What are the main business plan steps?

The main business plan steps cover the executive summary, business description, market analysis, competitive analysis, product or service, marketing and sales, operations plan, team and management, financial plan, and appendices.

How long should a business plan be?

It depends on the purpose. A traditional plan for banks and investors is usually 15 to 40 pages, a lean plan 3 to 10 pages, and a Business Model Canvas fits on one page. Clarity matters more than length.

What is the difference between a business plan and a feasibility study?

A feasibility study evaluates whether a business is worth pursuing in terms of market, costs, and return. A business plan explains how the business will be built, run, and grown, and usually follows once feasibility is established.

Do I need a business plan if I am not seeking funding?

Yes. A business plan is a thinking and management tool as much as a funding tool. A lean plan or one-page canvas reviewed regularly is often enough in this case.

What is the most important part of a business plan?

The executive summary matters most for first impressions, and the financial plan matters most under scrutiny. The summary decides whether the reader continues, and the numbers decide whether they are convinced.

How often should a business plan be updated?

Review it at least every quarter, and update it whenever something fundamental changes, such as pricing, target market, funding sources, or actual performance results.

Conclusion

Knowing how to write a business plan is not about filling in a template. It is about thinking systematically through every part of the business: the problem and customer, the market and competitors, the revenue model, marketing and operations, the team, and the numbers. Each of the business plan steps in this guide exposes an assumption that should be tested before it costs you money.

Your next step: start with a one-page canvas, expand it section by section using this business plan guide, and treat the financial plan as the last thing you finalize and the first thing you review. A good plan is not one that never changes, but one you keep learning from as the market changes.
