A one-page business plan is a short document that answers nine basic questions about who you serve, what you sell, how you earn money and what you will do next. You can write a useful draft in an afternoon. Its job is to make your thinking visible so you can test it, not to impress anyone.
Why keep it to one page
Long plans often become documents nobody reads again. A single page forces you to choose, and it is easy to update when facts change. It also works well as a conversation starter with a partner, mentor, bank or possible investor, many of whom will ask for a longer version later.
If you are only just starting out, pair this with the early steps in our guide on how to start a small business.
The nine sections
Draw a page with nine boxes, or use headings in a document. Write two to four plain sentences in each.
1. Customer
Describe the specific people or businesses you serve. Mention where they are, what they do and what they care about. “Independent physiotherapy clinics with one to five staff” is useful. “Everyone who wants to be healthy” is not.
2. Problem
State what is hard, slow, costly or annoying for that customer today. Use their words if you have heard them directly.
3. Offer
Explain what you sell and how it fixes the problem. Be concrete about what the customer receives and what is not included.
4. Why you
List your edge: experience, speed, location, price, a method or a relationship. Be honest. If your advantage is that you answer the phone, say so.
5. Pricing
Write your price or price range and the reason behind it. Our overview of pricing strategy for small businesses lays out methods to choose from.
6. Finding customers
Name your two or three main ways of reaching people, such as referrals, local partnerships, search, social posts or direct outreach. Pick channels you can actually maintain.
7. Costs
Split costs into one-time startup costs and monthly running costs. Include your own pay and tax set-asides, not only supplies and software.
8. Numbers
Do a basic calculation: monthly costs divided by profit per sale gives you how many sales you need to break even. If that number looks unrealistic, adjust the plan now rather than later.
9. Next 90 days
Choose three or four measurable goals. For example: sign five paying customers, finish the website, and set up bookkeeping.

| Section | Prompt to answer |
|---|---|
| Customer | Who exactly are they? |
| Problem | What hurts for them today? |
| Offer | What do they get from me? |
| Why you | Why would they pick me? |
| Pricing | What do I charge and why? |
| Finding customers | Where will they hear about me? |
| Costs | What does it cost to start and to run? |
| Numbers | How many sales to break even? |
| Next 90 days | What will I do first? |
A short worked example
Imagine a mobile bike repair service. The customer is commuters in one city who cannot spare a bike for days at a shop. The problem is downtime and inconvenience. The offer is repairs at the customer’s workplace or home, with a fixed price list. The edge is same-day service. Pricing is a call-out fee plus parts at a markup. Customers will come from workplace notice boards, cycling clubs and local shops. Costs include a van or cargo bike, tools, insurance and spare parts. The numbers show how many repairs per week cover costs. The first 90 days aim for twenty repeat customers.
Notice that none of this needed fancy language. Each line can be tested against reality.
How to use the plan after writing it
- Test the weak boxes first. Whatever you wrote with the least confidence is where to gather facts, such as customer interviews or price checks.
- Share it. Ask someone who knows your market to challenge it.
- Review monthly. Update numbers and goals with what you have learned.
- Expand only when needed. Lenders and investors may require sections such as market analysis and financial forecasts. Your one page becomes the summary.

Mistakes that weaken a plan
- Describing a customer too broadly to find them.
- Guessing costs without checking real quotes.
- Forgetting to include your own pay and tax.
- Setting goals with no dates or numbers.
- Treating the plan as final instead of as a working draft.

Final thoughts: block out two hours
Set a timer for two hours, draw nine boxes and fill each with your best honest answer, leaving a question mark where you do not know. Then pick the single question mark that worries you most and spend the next week finding the answer by talking to a real customer.
Frequently asked questions
How long should a business plan be?
For your own use, one page is enough. Banks and investors often want a longer document, but a clear one-page summary makes that easier to write.
Do I need a business plan to start a business?
It is not legally required in most places, but writing one reveals gaps in your idea before you spend money. It is also usually required when applying for loans or investment.
What should be in a business plan?
At minimum: your customer, the problem, your offer, pricing, how you will find customers, costs, break-even numbers and short-term goals.
How often should I update my plan?
Review it monthly in the early stages and at least once a year later. Update it whenever prices, costs or goals change significantly.
Can I use a template?
Yes. Templates are a helpful starting point as long as you fill them with your own specific facts instead of generic statements.
