Writing a Business Plan: Step-by-Step Guide

A strong business plan can help you succeed at any stage in your company’s growth.

When you launch, a business plan helps to prioritize and manage your funds. As you continue to evolve, it gives you a roadmap to execute new opportunities. And at any point in time, a business plan could be used to apply for loans and grants or set up a crowdfunding campaign.

Find out how to write a business plan for a small business that is designed to help you achieve your company’s unique goals.

Key Points

•   A business plan should start with an executive summary, which is a concise overview of your business, including its mission, vision, products/services, target market, and financial projections. It should grab attention and summarize the plan.

•   It should also include a detailed analysis of your industry, target audience, competition, and market trends to demonstrate demand for your product or service.

•   A business plan should provide realistic financial forecasts, including profit/loss statements, cash flow, and break-even analysis. Highlight how you’ll fund the business and achieve profitability.

•   Tips for an effective business plan include being specific, clear, and concise in your writing, using data and research to back up your claims, and revising and updating your plan regularly.

•   A business plan is important to both outline your own business goals and to show lenders or investors how the business will be run efficiently. This is important if you ever wish to apply for small business grants or loans.

The Importance of a Business Plan

Creating a business plan allows you to map out every crucial detail in launching and managing your company. Walking through each step helps you define your business goals, financial strategies, and both legal and organizational structures.

The document helps ensure that you focus on your core areas without getting distracted by opportunities that don’t support the plan. Externally, the business planning process helps identify funding needs and serves as support for financing applications, investor pitches, and even crowdfunding for small businesses.

When deciding how to make a business plan, first identify which type is better suited for your company. There are two primary categories: a traditional business plan and a lean startup plan.

Traditional Business Plan

A traditional business plan is the more in-depth option, discussing the company’s past, present, and future. The goal of writing a business plan is to provide a roadmap for the company. As such, it often includes:

•  A discussion of the broader market to identify both upcoming challenges and opportunities the business may face.

•  Any relevant expansion plans. The business plan generally outlines where the funding will come from (such as a small business loan) and what hiring needs to be done.

•  An explanation of duties for current employees.

•  A strategy in case certain setbacks occur.

•  A five-year forecast of company financials.

Lean Startup Plan

For a more basic business plan, you could opt for a lean startup model. Writing a lean startup model business plan requires less detail than a traditional plan and takes a more general approach to outlining the company’s information.

A lean startup business plan typically doesn’t have enough information to satisfy a lender or investor, but it can be a useful internal tool when you’re just starting out. It also provides the flexibility to experiment with business models and other details. In other words, it gives you more room to pivot as you gain experience with managing the company.

According to the Small Business Administration (SBA), elements of the lean startup plan include:

•  Partnerships: Highlight the strategic partnerships that will help your business operation. This may include suppliers or manufacturers.

•  Activities: In what ways will the company have a competitive advantage in the existing market? Things to consider here may be technology that could set you apart.

•  Resources: What resources will allow you to create value for customers? This may be staff, intellectual property.

•  Value proposition: What unique value does your company bring to the existing market?

•  Customer relations: How will consumers interact with your company? Will their experience be in-person or online?

•  Customer segments: Identify your target market. Defining and understanding who your target market is can help inform overall business and marketing strategies.

•  Cost structure: This section should explore the costs your business will face — such as labor or supplies. It can also be helpful to define whether your company will work on a cost-driven model or a value-driven model. Cost-driven models focus on lowering costs while value-driven models focus on creating premium value for customers.

•  Revenue streams: How is the company going to make money?

There are a variety of templates, examples, and online resources that can help business owners navigate how to write a lean startup business plan.

9 Steps to Writing a Business Plan

Here’s how to write a business plan step-by-step that can help you create a solid strategy for both the near-term and long-term. The following steps are for a traditional business plan.

Business owners may decide to pick and choose the sections that are most relevant for their goals.

1. Executive Summary

The executive summary provides a brief overview of your company as well as your goals. This section is particularly important if you’re applying for a small business loan or pitching new investors. Be direct with your funding goals, whether it’s receiving a certain loan amount or raising a specific amount of money.

Within no more than a few pages, the executive summary should outline what you’ll discuss in greater detail throughout the rest of the business plan. You may even opt to write this section last so you know exactly what you’re summarizing.

2. Business Overview and Structure

This section goes into more detail on the business, including the products or services you offer. Include information on why your company is (or will be) successful, such as a specific competitive advantage, unique expertise on your team, and intellectual property.

Also talk about your mission and vision statements to clearly communicate your goals and values. These can be updated over time as your company evolves. Finally, describe your target customer, location, and other structural details that are central to your business.

3. Market Analysis and Structure

Here’s where you show an assessment of your market. Discuss metrics and trends of the entire industry in which your company operates. This should largely discuss the competition and the demand for your product or service. Is your industry focusing major growth in one area, or price increases because of a general trend?

Also describe your various customer segments, including their general location and demographics. By the time a lender or investor finishes reading this section they should understand how your industry works and where your company fits in among the competition.

4. Management and Team

The strength of a company’s management team can be an important part of any business plan. Even if there are only a couple of co-founders at the moment, present their full bios and how each individual contributes to the company’s success. Larger businesses could include an organizational chart to illustrate the reporting structure of the team.

Another important aspect to consider when writing a business plan, regardless of a company’s size, is the legal structure and ownership of the company. You can also introduce any advisory board members who lend their expertise to the business.

5. Marketing Plan

Tee up your funding request by explaining how you plan to get sales or how your current sales come in. Whether you’re selling a product or a service, go in-depth about where you connect with customers, such as in-store or online. Also outline your pricing strategy and how that stacks up to the competition.

Next, describe your advertising strategy and any results that you’ve experienced so far. Are you advertising online or through traditional media channels? For more established companies, discuss any new, upcoming campaigns. You can also mention budget plans for your sales and marketing plans.

6. Operations Plans

This section may make sense if you want to give more detail on how your company operates, especially if you have multiple divisions rather than just a few team members. It can build off of information you included in the management section. Rather than focusing on each member’s expertise, here you would discuss the different responsibilities throughout the company.

Also provide details on operating expenses and overall budgets. You don’t need to go into revenue numbers yet, but instead talk about the capital and cash flow needed to run the business on a day to day basis. You may need to update your business plan if your company pivots to a new product or service.

7. Financial Projections

Your financial section includes both a historical account of your business finances (if you’re already established), as well as a forward-looking estimate, usually projecting the next three to five years. Data should include profit and loss statements, balance sheets, and cash flow statements.

Include projections for each of these documents and get as specific as possible if you’re a new enterprise. Graphic visuals can also help your numbers pack more of a punch, especially when showing trends over a period of time.

8. Funding Request

When writing a business plan to attract investors or apply for a small business loan, you’ll want to outline your exact financing needs and what you plan to accomplish with the funds. Describe how much you’ll need to launch if you’re a startup. Existing businesses can describe expansion plans, such as salaries for new positions, research and development for a new product, or a brand new location.

For a loan application, you may give details about your preferred repayment plan. For an investor pitch, address your valuation and how much equity you’re willing to give up for a specific investment. Some small business grant applications will like to see a business plan, too.

Tie all of this information back to your projections and how much revenue growth you expect from this potential funding.

9. Appendix and Supporting Documentation

The final component of creating a business plan is your supporting documentation in the appendix. This could include requested materials, like resumes or a business credit report (although lenders will frequently do their own credit check).

You may also include letters of recommendation, customer testimonials, and product pictures. Consider adding your incorporation documents and any legal contracts or licensing information that impacts your business.

Tips for Writing an Effective Business Plan

Tips for writing an effective business plan include:

•  Be clear and concise: Use simple language and avoid jargon to make the plan easy to understand.

•  Tailor to your audience: Adjust tone and detail depending on whether it’s for investors, lenders, or internal use.

•  Focus on the essentials: Include key sections like market analysis, financial projections, and business strategy without overloading with unnecessary details.

•  Use data and research: Back up claims with facts, market data, and financial evidence to build credibility.

•  Set realistic goals: Present achievable, measurable milestones for business growth and profitability.

•  Highlight your unique value: Clearly explain what differentiates your business from competitors.

•  Be flexible: Show an understanding of potential risks and outline contingency plans.

•  Revise and update: Regularly review the plan as your business evolves to ensure it remains relevant.

Common Mistakes to Avoid in Business Plan Writing

When writing a business plan, common mistakes to avoid include:

•  Being overly optimistic with financial projections, which can make the plan seem unrealistic.

•  Failing to research the market thoroughly, which can lead to inaccurate assumptions about customer demand and competition.

•  Lack of clarity or organization, which makes the plan hard to follow, diminishing its impact.

•  Ignoring potential risks or challenges, which makes the plan appear incomplete.

•  Using vague language instead of specific, actionable details may reduce the credibility and effectiveness of the plan.

The Takeaway

Understanding how to write a business plan can help business owners be better prepared for both requesting funding, like a small business loan, and actually running your business.

Writing a business plan requires quite a bit of research to make sure you can clearly communicate about your company and your industry as a whole. You may not need to follow all of these business plan steps, especially if you’re a new company, but you can still provide a well-informed analysis of your market, your company’s competitive advantage, and your future plans.

As your business grows and evolves, it can be helpful to regularly update your business plan in the appropriate areas. This could give you the agility to jump on opportunities as they arise when you already have a well-prepared plan that only needs minor changes. Writing a business plan is a particularly wise investment of your time regardless of your company’s current stage.
