How to Write a One-Page Business Plan
Most people skip the business plan because they imagine a thick document full of charts. They start buying things and find the real problems later — when the money is already spent.
You do not need forty pages. You need one sheet of paper and one honest hour. The US Small Business Administration (SBA) says a "lean" plan can take as little as one hour and is usually one page. This guide shows you how to fill that page, box by box.
Why a plan matters, even for a small side business
Starting is easy. Lasting is hard. US government data (BLS) shows what happens to new business locations over time: of those that opened in March 2013, about 80% were still open after one year, about half after five years, and about one in three after ten years.
A plan does not guarantee you will be in the surviving group. But it forces you to answer the questions that sink most new businesses: Who exactly will pay? How will they find you? What does it cost before the first sale?
Lean plan or traditional plan?
The SBA describes two types. A traditional plan is long and detailed — executive summary, market analysis, management, marketing, funding request, financial projections. Banks and investors often ask for it.
A lean plan covers only the key points on one page. It is perfect if you are testing an idea, starting next to your job, or just want clarity. You can always grow it into a full plan later.
The 9 boxes of a one-page plan
Draw nine boxes on a sheet. These are the parts the SBA lists for a lean plan. Fill them in this order — customers first, money last.
1. Customer segments — who exactly?
Not "everyone". Write one clear group. "Working parents within 5 km who need home-cooked lunch" is a customer. "People who like food" is not.
2. Value proposition — what problem do you solve?
One sentence. Why would this person choose you instead of what they do today? Faster, cheaper, more trusted, more personal?
3. Channels — how will they find you?
Be specific. Word of mouth, a local WhatsApp group, a market stall, a simple website, Google Maps listing. Two channels you will really use beat ten you only write down.
4. Customer relationships — how do you keep them?
One-time sale or regular customer? A loyalty card, a monthly order, a follow-up message after one week.
5. Revenue streams — how does money come in?
Per item, per hour, subscription, deposit plus balance? Write your price and why it is that price. If you sell your time, the hourly rate calculator helps you avoid charging too little.
6. Key activities — what must you do every week?
Cooking, delivering, posting, calling, accounting. If a task is not on this list, ask if it is really needed.
7. Key resources — what do you need to have?
Skills, tools, a vehicle, a licence, a small amount of starting capital. Mark what you already own and what you still need to buy.
8. Key partners — who helps you?
Suppliers, a friend who designs, an accountant, a shop that lets you display your product.
9. Cost structure — what does it cost?
Split into one-time costs (equipment, registration) and monthly costs (materials, phone, transport, insurance). Then use the break-even calculator to see how many sales you need just to cover them. That one number teaches more than any motivation video.
Three tests before you spend money
- The ten-people test: Show the idea to ten people from box 1. Ask what they would pay — and if they would pay today. Polite praise is not a sale.
- The worst-month test: If sales are half of what you hope, can you still pay the monthly costs from box 9 without borrowing?
- The time test: Count the weekly hours from box 6. Do they fit your life next to your job and family? Our guide on starting a business without quitting your job goes deeper.
A word about direct selling "business plans"
If someone shows you a compensation plan and calls it "your business plan", be careful. A compensation plan shows how a company pays — not whether you will earn. Fill your own nine boxes: who your customers are outside your team, what you must buy each month, and how many hours it takes. Then read the company's income disclosure. Our guide on how to read an MLM income disclosure shows what to look for.
Keep the plan alive
A plan in a drawer is useless. Put a date in your calendar every three months. Read the page, cross out what turned out wrong, and write what you learned. A plan that changes is a plan that works. The $100 Startup summary uses a similar one-page idea.
Questions people ask
What is a one-page business plan?
A short plan that fits the key parts of a business on one sheet: customers, the problem you solve, channels, relationships, revenue, activities, resources, partners and costs. The SBA calls it a lean startup plan.
How long should a business plan be?
For testing an idea or a small side business, one page is enough. Banks and investors usually want a longer traditional plan with financial projections.
What should I write first?
Start with your customer and the problem you solve. Money boxes come last, because prices and costs depend on who you serve.
Do I need a business plan for a side business?
It is not required, but it helps you catch mistakes before you spend money — especially costs and the time you really have each week.
How often should I update my plan?
Review it about every three months, or whenever something big changes, and correct what turned out to be wrong.
