Step 1: The lesson

How do you write a one-page business plan?

A business plan doesn't need to be 40 pages. For a new business, a one-page plan is often better: it forces you to be clear, and it's easy to update as you learn.

The point isn't to predict the future perfectly. It's to write down your assumptions so you can test them — and notice when one turns out to be wrong.

Update it monthly

Cross out assumptions you've proven or disproven. A plan that never changes probably isn't being used.

Step 2: See it

The one-page business plan

Problem, target customer, solution, how you make money, costs, how you'll reach customers, key milestones, and biggest risks.

  1. Problem

    What pain are you solving?

  2. Customer

    Who has it most?

  3. Solution

    What you offer and why it's better.

  4. Revenue

    Price and how customers pay.

  5. Costs

    Fixed and variable, plus break-even.

  6. Reaching customers

    Your main marketing channels.

  7. Milestones

    What you'll accomplish, by when.

  8. Risks

    What could go wrong, and your plan B.

Step 3: Real-world example

Marcus's one-page plan

  • Problem: students' white sneakers get dirty; cleaning them well is hard and shops are far away.
  • Customer: students who wear white sneakers to events.
  • Solution: 24-hour cleaning with pickup at school. Revenue: $12 standard, $20 rush, $30/month Clean Club.
  • Costs: $5 per pair; $300/month fixed. Break-even: 43 pairs/month.
  • Reaching customers: before-and-after posts, referrals, weekend market.
  • Milestones: 60 cleans in October; 15 Clean Club members by December.
  • Risks: summer slowdown; school rules on selling at school. Plan B: partner with a local shop.

Step 4: Knowledge check

Step 5: Summary

Summary: Business Plans

A one-page plan covers problem, customer, solution, revenue, costs, reaching customers, milestones, and risks. It turns assumptions into things you can test, and it should be updated as you learn.
