How to Write a Simple Business Plan (One-Page Template, 2026)

Category: BusinessLast updated: November 20267 min read

Quick answer: A simple business plan answers seven questions on one page: what you sell, who buys it, what problem it solves, how you reach customers, how you make money, what it costs to run, and what you will achieve in the next 12 months.

You do not need a 40-page document to start a business. Most small owners need a clear one-page plan they can actually use. This Biz Reporterz guide walks you through each section with examples, and the free generator below turns your answers into a ready one-page plan.

What Is a Business Plan?

A business plan is a written description of how your business will make money and grow. The US Small Business Administration describes two main styles: a detailed traditional plan and a short, lean plan.

  • Lean plan: one page, quick to write and easy to update.
  • Traditional plan: longer, often needed for bank loans or investors.
  • Goal: make decisions clearer, not to impress anyone.
Example 1Nadia wants to start a home bakery. Her one-page plan says she sells custom birthday cakes to busy parents in her area, takes orders on Instagram and WhatsApp, charges £35 to £60 per cake, spends about £400 a month on ingredients and packaging, and aims for 40 orders a month within a year.

Lean Plan vs Traditional Plan

Feature Lean (one-page) plan Traditional plan
Length 1 page 10 to 40+ pages
Time to write An hour or two Days or weeks
Best for Starting out, testing ideas Loans, investors, big projects
Updates Easy, monthly Harder, yearly
Hook pointMost plans fail on one line: who exactly is the customer? Get that right and the rest of the plan almost writes itself.

How to Write a Simple Business Plan

1. Your offer

Describe in one sentence what you sell. Avoid jargon.

2. Your customer

Be specific: “working parents within 5 miles,” not “everyone.”

3. The problem you solve

Why would they pay you? Time saved, better quality, lower price or convenience.

4. How you reach them

List one or two channels you will actually use, such as Instagram, Google Business Profile or local shops.

5. Prices and costs

Write your price, your main monthly costs and how many sales you need to cover them.

6. Your 12-month goal

Pick one measurable goal, like monthly sales or number of customers.

Short answers work best.

Sections a Bank or Investor May Ask For

  • Executive summary: the whole plan in a few lines.
  • Market analysis: size of the market and competitors.
  • Team: who runs the business and their experience.
  • Financial projections: sales, costs and cash flow forecasts.
  • Funding request: how much you need and how you will use it.
Biz Reporterz TipPut your one-page plan where you see it every week and update the numbers monthly. A plan that changes with real results is far more useful than a perfect document nobody reads.

Who Needs a Simple Plan?

  • New founders: test whether an idea can pay for itself.
  • Side hustlers: decide if it is worth more of your time.
  • Freelancers: set prices and income targets.
  • Small shops: plan a new product or location.

Common Mistakes

  • Describing the customer as “everyone.”
  • Guessing costs instead of listing them.
  • Setting goals with no number attached.
  • Never updating the plan after launch.

Frequently Asked Questions

How long should a small business plan be?

For most new small businesses, one page is enough to start. Lenders may ask for a longer, traditional plan.

Do I need a business plan to start?

Not legally in most cases, but a simple plan helps you avoid costly mistakes.

What is break-even?

The number of sales needed to cover your costs, before you make a profit.

How often should I update my plan?

Monthly for the numbers, and whenever something big changes.

Can I use a template?

Yes. Templates help, but your own real numbers are what make the plan useful.

What should I include for a bank loan?

Usually a traditional plan with financial projections and how you will repay the loan.

Final Thoughts

  • Start with a one-page plan.
  • Be specific about your customer and your costs.
  • Check break-even before you spend.
