How to Use AI to Write Your Small Business Plan
Free. No MBA Required.

You don’t need to know how to write a business plan. You need to know your own business. ChatGPT handles the structure, the professional language, and the format. You provide the knowledge only you have. These five prompts walk you through every section of a complete business plan — suitable for a UK startup loan, a US SBA application, or simply getting clear on your own direction. Free. No consultant needed.

A business plan is the document that stands between most small business owners and the funding or clarity they need.

Need a Start Up Loan? You need a business plan. Approaching an investor? Business plan. Applying for a bank overdraft facility? Business plan. Even if you are not seeking funding, the process of writing one forces you to think clearly about your market, your finances, and your direction in ways that make better decisions every day afterwards.

The reason most small business owners avoid writing one is not lack of knowledge about their business — it is not knowing how a business plan is supposed to be structured, what language it should use, and what lenders or investors specifically want to see in each section.

That is exactly what ChatGPT handles. You bring the knowledge. ChatGPT provides the structure and the professional language. The five prompts below walk through every major section in order.

⚠️ One important rule before you start
ChatGPT drafts the structure and language. You are responsible for the accuracy of every figure, projection, and factual claim. Before submitting any business plan to a lender or investor, have your accountant review the financial sections. A well-structured plan with inaccurate figures will damage your credibility. A well-structured plan with accurate, realistic figures will build it.

Prompt 1 — The Executive Summary

The executive summary is always written last in practice but read first by every lender. It is a concise, compelling overview of the entire business that answers three questions: what does this business do, why will it succeed, and what does it need from us?

Most business owners struggle with the executive summary because it requires stepping back from the detail they know well and presenting the big picture confidently and concisely. This is exactly what ChatGPT does best.

📋 CRAFT Prompt 1 of 5 — Executive Summary
You are a professional business plan writer helping a small business owner write an executive summary for a business plan.
 
My business details:
- Business name: [Name]
- Business type: [e.g. "a sole trader plumbing business" / "a limited company hair salon" / "a start-up online retail business"]
- Location: [Town/city and area served]
- What the business does: [2-3 sentences describing your product or service in plain English]
- Who the customers are: [Brief description of target customer]
- What makes us different from competitors: [Your key competitive advantage — e.g. "10 years' experience, 5-star rated, specialising in gas safety work that others won't touch"]
- Current stage: [e.g. "pre-launch seeking startup funding" / "trading for 2 years, seeking expansion funding" / "established business seeking working capital"]
- Funding required (if any): £[X] / $[X] for [brief purpose]
 
Write a professional executive summary of 200-250 words. It should:
- Open with a compelling one-sentence description of the business and its opportunity
- Cover what the business does, who it serves, and why there is a genuine market for it
- State the competitive advantage clearly and specifically
- If funding is being sought: state the amount and purpose clearly in the final paragraph
- Use confident, professional language — the tone of someone who knows their business and believes in it
 
Do not use buzzwords like "innovative," "disruptive," or "game-changing." State facts and specifics.

Prompt 2 — The Market Analysis

Lenders want to know that you understand the market you are entering — that there is genuine demand for what you offer, that you know who your ideal customer is, and that you have a realistic view of your competition. The market analysis section demonstrates this.

You do not need to commission expensive market research. You need to describe what you already know from running or planning your business, and ChatGPT will structure it in the format lenders expect.

📋 CRAFT Prompt 2 of 5 — Market Analysis
You are a professional business plan writer helping a small business owner write a market analysis section.
 
My business: [Business name], a [brief description] based in [location].
 
My target customers:
- Who they are: [e.g. "homeowners aged 35-65 in South Yorkshire with properties over 10 years old"]
- What problem I solve for them: [e.g. "they need a reliable, qualified plumber they can trust for ongoing maintenance and emergencies"]
- Why they choose me over competitors: [e.g. "local reputation, Gas Safe certified, 24-hour emergency response"]
 
My competitors:
- Main competitors: [List 2-3 — e.g. "national companies like British Gas HomeServices, local sole traders, and larger regional plumbing firms"]
- My competitive advantage over them: [e.g. "more personal service than nationals, more qualified than many sole traders, faster response than larger firms"]
 
Market context:
- [Any relevant facts about the size or growth of your market you know — e.g. "the UK has 3.5 million domestic boilers requiring annual servicing" / "demand for beauty services has grown by X% since 2023" — or leave blank and ask ChatGPT to describe the general market context for your sector]
 
Write a professional market analysis section of 300-350 words covering: market overview, target customer profile, competitive landscape, and our competitive positioning. Use confident, specific language. Avoid vague claims without factual grounding.

Prompt 3 — The Operations Plan

The operations plan answers a question lenders care about deeply: can this business actually execute what it is promising? It covers staffing, premises, equipment, suppliers, and the day-to-day processes that make the business function. For many small business owners, this is the section they feel most confident about — because they know their operations instinctively — but struggle to articulate in the formal language a business plan requires.

📋 CRAFT Prompt 3 of 5 — Operations Plan
You are a professional business plan writer helping a small business owner write an operations plan section.
 
My business: [Business name], a [brief description] based in [location].
 
Operational details:
- Staffing: [e.g. "currently sole trader with plans to hire one apprentice within 12 months" / "3 full-time staff plus 2 part-time" / "owner-operated with no employees"]
- Premises: [e.g. "home-based with no customer-facing premises" / "leased salon premises at [location]" / "mobile business operating from a van"]
- Equipment / tools: [Key equipment — e.g. "fully equipped van, all tools owned outright" / "salon chair and equipment, purchased" / "laptop, phone, software subscriptions"]
- Key suppliers: [e.g. "materials from [supplier], consumables from [supplier]" — or leave blank]
- Typical working week: [Describe roughly — e.g. "Monday to Friday, 3-4 jobs per day, evenings for quotes and admin" / "Tuesday to Saturday, 8 client appointments per day plus 1 day admin"]
- Qualifications and certifications: [e.g. "Gas Safe registered, public liability insurance, NVQ Level 3" / "NVQ Level 3 Hairdressing, fully insured"]
- Systems and processes: [e.g. "job management via [software], invoicing via [software]" — or leave blank]
 
Write a professional operations plan section of 250-300 words. It should demonstrate that this business has the infrastructure, skills, and processes in place to deliver on its promises. Use clear, confident language that shows operational competence.

Prompt 4 — Financial Projections

This is the section most small business owners find most daunting — and the one lenders scrutinise most carefully. The good news is that ChatGPT does not invent financial figures for you. What it does is take the figures you provide and structure them into a coherent financial narrative with realistic commentary that lenders expect to see alongside the numbers.

🔒 Accuracy is everything in this section
Only include figures you genuinely believe are achievable. Lenders have seen thousands of business plans and immediately spot projections that are unrealistically optimistic. A conservative, well-justified projection is significantly more credible than an ambitious one with no supporting rationale. Have your accountant review this section before submission.
📋 CRAFT Prompt 4 of 5 — Financial Projections
You are a professional business plan writer helping a small business owner write a financial projections narrative section.
 
My business: [Business name], a [brief description].
 
My financial estimates for year 1 (be as specific as possible):
- Projected monthly revenue (average): £[X] / $[X]
- Peak months and why: [e.g. "December and August for seasonal demand"]
- Quieter months: [e.g. "January and February typically 20% below average"]
- Main costs:
  * Materials/stock: £[X]/month
  * Staff (if any): £[X]/month
  * Premises/rent: £[X]/month
  * Insurance: £[X]/year
  * Vehicle/equipment: £[X]/month
  * Other: [describe]
- Break-even point (rough estimate): [e.g. "I need to achieve £[X] per month to cover all costs"]
- Existing revenue (if already trading): £[X] per month average over last [X] months
 
Write a financial projections narrative section of 250-300 words. It should:
- Summarise the projected revenue and cost structure for year 1
- Explain any seasonal patterns and the assumptions behind them
- State the break-even point and when you expect to reach consistent profitability
- Acknowledge key financial risks and how they will be managed
- Use confident but realistic language — lenders respect honest projections
 
Note: I will attach a detailed spreadsheet of monthly figures separately. This section is the written narrative that accompanies those figures.

Prompt 5 — The Funding Ask

The funding requirements section is where the business plan converts. After reading four sections that establish credibility and viability, the lender or investor reaches this section and makes their decision. It must be specific, credible, and clearly show how the funding will be used and how it will be repaid.

📋 CRAFT Prompt 5 of 5 — Funding Requirements
You are a professional business plan writer helping a small business owner write a funding requirements section.
 
My business: [Business name], a [brief description].
 
Funding details:
- Amount requested: £[X] / $[X]
- Type of funding: [e.g. "Start Up Loan (UK)" / "SBA loan (US)" / "bank business loan" / "private investment" / "grant application"]
- What the funding will be used for:
  * [Item 1 and cost — e.g. "Equipment purchase: £4,000"]
  * [Item 2 and cost — e.g. "Initial stock: £2,000"]
  * [Item 3 and cost — e.g. "Working capital for first 3 months: £6,000"]
  * [Total should match amount requested]
- How the loan will be repaid: [e.g. "from projected trading revenue, with monthly repayments of approximately £[X] over [X] years"]
- Any existing investment or owner contribution: [e.g. "I am contributing £[X] of my own funds" — shows lender commitment]
 
Write a professional funding requirements section of 200-250 words that:
- States the amount and type clearly upfront
- Provides an itemised breakdown of exactly how the funds will be used
- Explains the repayment plan credibly
- References how this funding connects to the financial projections in Section 4
- Ends with a confident statement of the expected return on this investment (for the business, not the lender)
 
Keep language precise and professional. Avoid vague statements like "various expenses." Every figure should have a clear purpose.

UK and US specific considerations

🇬🇧
UK — Start Up Loans and British Business Bank
The UK Government’s Start Up Loan scheme (delivered via the British Business Bank) offers loans of £500 to £25,000 at a fixed 6% interest rate. They require a full business plan including all five sections above, plus a personal survival budget and a cash flow forecast for 12 months. Use the prompts above, then add the cash flow spreadsheet separately. Your Start Up Loan application also includes free mentoring support.
🇺🇸
US — SBA Loans and SCORE Mentoring
SBA 7(a) loans are the most common funding route for US small businesses. SBA lenders require a business plan covering all five sections above, plus a personal financial statement and 3 years of financial projections (or a detailed first-year plan for startups). SCORE (score.org) offers free mentoring from retired executives who can review your plan before submission — strongly recommended.

After the first draft — what to do next

Once you have run all five prompts and assembled the sections into a single document, do three things before submitting anywhere:

  • Read it aloud. The single most effective editing technique. Anything that sounds unnatural or doesn’t sound like something you’d actually say about your business needs adjusting.
  • Check every figure. Every number in the financial sections must be one you believe is accurate and achievable. Change anything ChatGPT estimated that does not reflect your actual situation.
  • Have your accountant review it. For any application that involves a lender or investor, professional sign-off on the financial sections is essential. This is not optional. It protects you and it significantly improves your credibility.
✅ The real value of writing a business plan
Even if you never show your business plan to a lender, the process of writing it is valuable. It forces you to think clearly about your market, your costs, your break-even point, and your competitive position. Most small business owners who write a proper plan — even using AI to help structure it — report that they make significantly better decisions in the months that follow. The plan is not the output. The clarity it creates is.

Frequently asked questions

Yes. AI is well-suited to business plan writing because a business plan follows a predictable structure that ChatGPT can produce reliably given the right context. What AI cannot do is invent the knowledge only you have: your realistic financial projections, your genuine competitive advantage, and your specific market knowledge. The prompts in this guide ask you to provide that knowledge and use ChatGPT to structure it professionally.
Banks assess the quality and credibility of the content, not the method used to write it. An AI-assisted business plan with accurate, well-structured, credible financial projections will be evaluated favourably. The key is to provide ChatGPT with accurate information and verify all figures with your accountant before submitting. The AI handles the structure and language; you are responsible for the accuracy.
Using the five prompts in this guide, most small business owners can produce a complete first draft of all five major sections in a single afternoon — typically 2 to 4 hours. Most of the time is spent gathering your own information (financial figures, market knowledge, operational details) rather than on the writing itself. ChatGPT handles each section in under 2 minutes. Allow additional time for review and accountant sign-off.
No. A business plan is a comprehensive document covering all aspects of a business — its model, market, operations, finances, and strategy — typically used for securing funding or strategic direction. A business proposal is a shorter, targeted document used to pitch for a specific contract or project. This guide covers the business plan. For business proposals, see our ChatGPT for Business Proposals guide.
