Business Plan Fundamentals

How to write a business plan that actually helps you build and grow.

By FORGE TeamUpdated January 2024

Do You Even Need a Business Plan?

Controversial opinion: most startups do not need a traditional 50-page business plan. What they need is clarity.

**When you DO need a formal plan:** - Applying for grants or competitions that require one - Seeking bank loans or formal investment - Working with government programs that mandate it

**What you ALWAYS need (formal plan or not):** - A clear understanding of your customer - A defined problem and solution - A model for making money - A plan for reaching customers - Basic financial projections

This guide teaches you how to create a lean, useful plan - not a document that sits in a drawer.

The One-Page Plan

Before writing a full plan, complete this one-page version:

**Problem:** What specific problem are you solving? (2 sentences)

**Customer:** Who has this problem? Be specific. (Age, location, behavior, income level)

**Solution:** How does your product solve it? (2 sentences)

**Unique Value:** Why would someone choose you over alternatives? (1 sentence)

**Revenue Model:** How will you make money? (List pricing approach)

**Channels:** How will customers find you? (List top 3 channels)

**Cost Structure:** What are your main costs? (List top 5 expenses)

**Key Metrics:** How will you measure success? (List 3-5 numbers you track)

**Unfair Advantage:** What do you have that cannot be easily copied? (1 sentence)

If you can complete this page clearly, you understand your business. If you struggle, you need more customer research before writing anything longer.

Pro Tips

  • Revisit your one-page plan monthly and update it
  • Share it with your mentor for feedback
  • Keep it visible - pin it above your desk or set it as your phone wallpaper

Financial Projections

You do not need to be an accountant. You need to understand basic numbers:

**Revenue Projection (How much money comes in):** - How many customers will you have? (Month 1, Month 6, Month 12) - How much will each customer pay? - Revenue = Customers x Price - Be conservative. Then cut that number in half.

**Cost Projection (How much money goes out):** - Fixed costs: Things you pay regardless of sales (hosting, subscriptions, rent) - Variable costs: Things that increase with sales (materials, transaction fees) - One-time costs: Things you pay once (equipment, legal registration)

**Break-Even Analysis:** - At what point do your revenues cover your costs? - How many customers do you need to reach that point? - How long will it take?

**Cash Flow:** - When does money come in vs. when does it go out? - Many profitable businesses fail because they run out of cash. Timing matters.

Use a simple spreadsheet. Do not buy expensive software.

Market Analysis

You need to understand the market you are entering:

**Market Size:** - TAM (Total Addressable Market): Everyone who could use your product - SAM (Serviceable Addressable Market): The portion you can realistically reach - SOM (Serviceable Obtainable Market): The portion you can capture in the near term

**Competition:** - Who else solves this problem? (Direct competitors) - What alternatives do people use? (Indirect competitors - including "do nothing") - What are their strengths and weaknesses? - Where is the gap you can fill?

**Trends:** - Is the market growing or shrinking? - What technology or social changes affect your market? - Are there regulatory changes coming?

Do not pretend you have no competition. Investors and mentors see through that immediately. Show that you understand the landscape and have a clear differentiation.

Warning

Be honest about your market size. Claiming a billion-dollar TAM for a local service undermines your credibility.
