Prompt

Act as a small-business consultant who writes short, honest business plans that can be read in three minutes.

Business details:
- Business: {{business}}
- Main customer: {{customer}}
- Offer and price: {{offer}}
- Current stage: {{stage}}
- What the plan is for: {{purpose}}

If essential information is missing (fixed costs, startup investment, team), ask me before writing or leave it clearly marked.

Write a one-page plan with these sections, in this order:
1. One-sentence summary: what we do, for whom and why they would choose us.
2. Problem: what hurts for the customer and how they solve it today.
3. Solution and value proposition: how we differ from those alternatives.
4. Target customer: a concrete profile and the first expected customers.
5. Competition and alternatives: 3 at most, without judging them without data.
6. Revenue model and pricing.
7. Sales and acquisition channels.
8. Team and key resources.
9. Basic numbers: startup investment, monthly fixed costs, margin per sale and break-even point with the formula (fixed costs ÷ unit margin). Use [FILL IN] where data is missing.
10. Measurable milestones for the next 90 days.
11. Top three risks with mitigation.
12. If the plan is for a bank, partners or a grant: exactly what is being requested and how it will be used.

Constraints:
- 600 words maximum; short sentences.
- Do not invent figures, market shares or customers. Label every assumption as "assumption".
- This is not financial or legal advice; recommend reviewing the numbers with an accountant.

Format: short headings and bullet points. At the end, list the data still needed to complete the plan.

How to use it

  1. Fill in the variables with your real business. 2. Answer any questions the model asks. 3. Replace every [FILL IN] with your figures and check the break-even point with an accountant before presenting it.

Usage example

Business: self-service laundromat with pickup · Customer: local families and students · Offer: wash and dry $9, pickup $4 · Stage: idea · Purpose: bank.

Sample output

Summary

A specialty coffee shop with a coworking area for remote workers and college students who want great coffee and a quiet place to work without renting an office.

Problem

  • Working from home is isolating and distracting; regular cafés are not built for staying for hours.
  • Traditional coworking spaces require monthly memberships that do not suit occasional use.

Solution and value proposition

Quality coffee from $3 and a 10-day coworking pass for $99, no commitment. Reliable Wi-Fi, outlets at every seat and a quiet zone.

Revenue model

  • Coffee and pastries (assumption: 60% of revenue).
  • Coworking passes (assumption: 40%).

90-day milestones

  1. Lease signed by day 30.
  2. 50 passes pre-sold before opening (assumption).
  3. 120 coffees a day by the end of month three (assumption).

Top risks

  • Laptop campers on one coffee: time limit for non-pass seating.

Frequently asked questions

Is a one-page plan enough to apply for a loan?

It works as a first document, but many lenders also ask for detailed financial projections, often for 3 years. This summary helps you get your thinking in order first.

How do I calculate the break-even point?

Divide your monthly fixed costs by the margin each sale leaves (price minus variable costs). The result is how many sales per month you need to stop losing money.
