How to Write a Business Plan

A business plan is not a document you hand to people. It is the thinking you do before you start spending money. Done right, it's a working tool you update every quarter. Done wrong, it's 40 pages no one reads. This guide shows you what each section is actually for and how to make yours useful.

1. Why bother writing one at all

Three real reasons to write a business plan: (a) to think clearly about whether the business will work before you risk your savings; (b) because bankers, investors, and SBA loan officers will ask for one; (c) to align your team around the same goals.

If none of those apply to you, you don't need a formal plan, you need a one-page lean canvas (covered separately). For everyone else, expect to spend a weekend on the first draft and a few hours each quarter updating it.

2. Executive Summary

One page. Two paragraphs minimum, four maximum. The executive summary is the only section many readers will read, so it must stand alone. Write it last, after you've done the thinking.

It should answer: What does the business do? Who is it for? Why now? Why are you the right person to build it? What do you need from the reader? Put numbers in: target revenue year one, target customers, funding required if any.

3. Problem & Solution

State the problem your business solves in a single sentence a stranger would understand. Then state your solution. If your solution is not obviously better than what people do today, the business will struggle.

What strong problem statements look like: "Working parents in our zip code drive 30+ minutes for affordable after-school care." Specific, measurable, and obvious why it matters.

What weak problem statements look like: "There is a lack of innovation in personal wellness." Vague, untestable, and easy to ignore.

4. Market & Customer

Two questions: Who is your customer? and How many of them are there?

Describe your customer

One real person, by name if needed. "Maria, 38, lives in our zip code, works full-time, has two school-age kids, makes $52,000/year, currently pays $185/week for after-school care 25 minutes from home." Real customer descriptions beat demographic statistics every time.

Size your market

How many "Marias" are there in your reachable market? You don't need a global market estimate. You need a believable local number. Census data, your city's economic development office, trade associations, and Google searches will get you 80% of the way.

Why they will choose you

List your top three competitors. List one specific thing you do better than each. If you can't answer this honestly, refine your idea before you spend money on it.

5. Business Model

How do you make money? Write the exact sentence: "I charge [X] for [thing] and my cost per [thing] is [Y], leaving [Z] gross profit per unit." Then multiply by units to estimate revenue. If you can't fill in those numbers honestly, you're not ready to launch yet.

Pricing strategy

State your initial price and how you arrived at it. We have a separate guide on pricing your products and services that walks through cost-plus, value-based, and competitive pricing.

Revenue projections

Three numbers: Year 1, Year 2, Year 3. Show your math. Investors and bankers can spot fake hockey-stick projections in seconds. Conservative is more credible than aspirational.

6. Operations

How does the business actually run, day to day? Cover: location and facilities, suppliers and key vendors, technology stack, hours of operation, and your weekly schedule for the first three months. Be boringly specific. Real businesses run on systems, not vision statements.

7. Team

If it's just you, write what you do well and what you don't. Identify the two skills the business needs that you don't have, and how you'll fill them (hire, contract, learn, find a co-founder). If you have a team, give each person's role and the single most important thing they're accountable for.

8. Financials

Three statements: startup costs, monthly cash flow forecast (12 months), and revenue projection (3 years). Use real numbers from real quotes, not internet estimates.

Startup costs

Everything you must pay before you serve your first customer. Equipment, inventory, deposits, software, marketing, legal, working capital. Add a 20% contingency.

Cash flow

Cash in minus cash out, month by month, for 12 months. Most businesses fail from running out of cash, not from running out of profit. This forecast is your most important financial document.

Revenue projection

Year 1 monthly, Year 2 quarterly, Year 3 annually. Show realistic assumptions: how many customers, at what price, with what growth rate.

9. The Ask (if you're seeking funding)

State exactly how much you're asking for, what you'll use it for line by line, what you're offering in return (loan terms, equity percentage, etc.), and how the lender or investor gets paid back. Vague asks get vague answers.

10. Mistakes to avoid

• Hockey-stick revenue projections. If your plan shows revenue going from $0 to $10M in three years with no comparable business in your market doing similar numbers, no one believes you.
• Vague competitive analysis. "We have no real competition" tells readers you haven't done the research. Everyone has competition, even if it's "doing nothing."
• Ignoring cash flow. Profitable businesses go bankrupt every day because they can't pay bills while waiting for customers to pay them. Your cash flow forecast is more important than your P&L projection.
• Forty-page narratives. Bankers read ten pages, max. Investors read three. Make your plan dense, not long.
• Writing it once and forgetting it. Update quarterly. Compare actuals against projections. Learn why you were wrong and adjust.
