Start with the idea prompts, especially the one where the AI interviews you, then work through market, operations, and financials. Paste each prompt into ChatGPT, Claude, or Gemini and replace every [BRACKET] with your real details. The AI can organize your thinking and write clean sections, but it does not know your local market or your costs. It will also produce convincing market statistics that may be wrong, so these prompts tell it to mark gaps with [NEEDS SOURCE] instead. Fill those with real research and supplier quotes. Have an accountant review your financials, and keep sensitive figures such as personal financial details out of public chatbots.
Shaping the idea
Stress test a business idea
Before you spend money or write the full plan.
Act as a skeptical small business advisor. My idea: [DESCRIBE BUSINESS IDEA]. Target customers: [CUSTOMERS]. Location or market: [MARKET]. List the 10 biggest risks or weak assumptions, rank them by how likely they are to sink the business, and for each suggest a cheap way to test it in the next 30 days.
Interview me to build the plan
When you know your business but not how to put it on paper.
I want to write a business plan for [BUSINESS IDEA]. Interview me one question at a time to gather what a plan needs: the problem, customers, offer, pricing, competition, marketing, operations, team, startup costs, and goals. After each answer, ask a sharper follow up if my answer is vague. When done, summarize everything in a structured outline.
Write a one page plan
For a quick plan you can share or build on.
Write a one page business plan for [BUSINESS NAME], a [BUSINESS TYPE] in [LOCATION]. Use these notes: [PASTE NOTES]. Sections: problem, solution, target customer, competition, how we make money, marketing, key milestones, startup costs, and what we need. Keep it tight, plain, and under 500 words.
Define the problem and solution
For the opening section of the plan.
Here is my business idea: [IDEA]. Write a clear problem statement explaining who has the problem, how they deal with it today, and what that costs them. Then write a solution statement explaining what we offer and why it is better. Keep each under 120 words and avoid hype words.
Write a mission and vision statement
When the plan needs a short statement of purpose.
Write five mission statements and five vision statements for [BUSINESS NAME], which [WHAT THE BUSINESS DOES] for [CUSTOMERS]. Our values are [VALUES]. Keep missions under 25 words and visions under 20 words, specific to us rather than generic, and explain which pair you would choose.
Choose a business model
When you are unsure how to price and package the offer.
I want to sell [PRODUCT OR SERVICE] to [CUSTOMERS]. Compare four ways I could make money, such as one time sales, subscription, packages, retainers, or commission. For each, explain cash flow, customer appeal, workload, and risks for a small business like mine. Recommend one to start with and explain why.
Write a lean canvas
For a quick one page view of the whole business.
Fill in a lean canvas for [BUSINESS IDEA] using these notes: [NOTES]. Sections: problem, customer segments, unique value proposition, solution, channels, revenue streams, cost structure, key metrics, and unfair advantage. Mark any box where my notes are too thin and tell me what to find out.
Market and competition
Plan market research
Before writing the market section.
I am starting [BUSINESS TYPE] in [LOCATION] for [TARGET CUSTOMERS]. List the questions my market research needs to answer, where to find free data for each (government statistics, industry groups, local records, competitor websites, customer interviews), and how to estimate the number of potential customers in my area. Do not invent figures.
Write a market analysis section
When you have research and need it written up properly.
Write the market analysis section of a business plan for [BUSINESS NAME] using only this research: [PASTE RESEARCH AND SOURCES]. Cover the target market, its size, trends, and customer needs.

Write customer personas
To make the customer section concrete.
Based on these notes about my likely customers: [NOTES OR INTERVIEW SUMMARIES], write three customer personas for [BUSINESS NAME]. For each, give a name, situation, goals, frustrations, how they choose a provider, and what would make them buy from us. Keep them grounded in my notes rather than stereotypes.
Write customer interview questions
Before you trust your assumptions.
I want to validate [BUSINESS IDEA] by talking to [NUMBER] potential customers. Write 12 interview questions that uncover real behavior and spending, not polite opinions. Avoid leading questions like Would you buy this. Include a short intro script and tips for running the conversation.
Write a SWOT analysis
A common section lenders and partners expect.
Write a SWOT analysis for [BUSINESS NAME] using these notes: [NOTES ON THE BUSINESS, MARKET, AND COMPETITORS]. Keep each point specific to us, not generic. Then add three strategies that use a strength to grab an opportunity or reduce a threat.

Write the team section
For the people section lenders read closely.
Write the management and team section for my business plan. Team members and backgrounds: [NAMES, ROLES, EXPERIENCE]. Advisors or partners: [ADVISORS]. Roles we will hire in year one: [PLANNED HIRES]. Show why this team can run this business and how we will cover skill gaps.
Plan milestones
To turn the plan into a schedule.
Create a 12 month milestone plan for launching [BUSINESS NAME]. Include key steps such as registration, funding, location, hiring, launch, and first customers, with target months, owners, and how we will know each milestone is done. Start from where I am now: [CURRENT STATUS].
Write a risk section
When investors or lenders ask what could go wrong.
List the main risks for [BUSINESS NAME], a [BUSINESS TYPE] in [LOCATION], across market, financial, operational, legal, and people risks. For each, rate likelihood and impact as low, medium, or high, and give a practical way to reduce it. Base it on these details: [DETAILS].

Financials and funding
List startup costs
Before building your budget.
List the typical startup costs for a [BUSINESS TYPE] in [LOCATION] in a table with categories such as equipment, deposits, licenses, inventory, fit out, marketing, software, and working capital. Do not fill in amounts; leave a column for my quotes and a column for notes on what to ask suppliers.
Build a simple financial forecast
When you need numbers but do not know where to start.
Help me build a 12 month financial forecast in a spreadsheet. Inputs: price [PRICE], expected customers per month [CUSTOMERS PER MONTH], cost per sale [COST PER SALE], monthly fixed costs [FIXED COSTS], and startup costs [STARTUP COSTS]. Give me the sheet layout, each formula, and the break even calculation. Tell me which assumptions are most worth testing.
Explain my numbers in plain words
To turn a spreadsheet into readable text.
Here are my forecast numbers: [PASTE FORECAST OR KEY FIGURES]. Write the financial summary section of the business plan in plain English: expected revenue, costs, margins, break even point, and cash needs. Note the key assumptions behind the numbers and flag anything that looks unrealistic.
Write a funding request
For lenders, grant programs, or investors.
Write the funding request section for [BUSINESS NAME]. We are asking for [AMOUNT] as [LOAN OR INVESTMENT]. The money will be used for [USE OF FUNDS].

After the rest of the plan is done.
Using this full business plan: [PASTE PLAN], write an executive summary under 400 words. Cover the business, the problem and solution, target market, competitive advantage, team, financial highlights, and the funding ask. Write it last, but make it strong enough that someone who reads only this page understands the business.
Review my plan like a lender
Before you send the plan to anyone with money.
Read my business plan as a bank loan officer would: [PASTE PLAN]. List the questions you would ask, the weak spots in my assumptions, missing information, and anything that would make you say no. Then give me a prioritized list of fixes before I submit it.
Questions people ask
Can ChatGPT write a business plan?
ChatGPT, Claude, and Gemini can structure and write every section of a business plan, but only from the information you give them. They do not know your local market, real costs, or customers, and they may invent market figures that look official. Use AI to interview you, organize ideas, and draft text, then fill in real research and real quotes yourself.
What is the best AI prompt for a business plan?
The most useful first prompt is one that asks the AI to interview you, one question at a time, about your problem, customers, pricing, competition, and costs. That gives it the raw material to write a plan that is actually about your business. The 'Interview me to build the plan' prompt above does exactly that.
Will a bank accept an AI written business plan?
Lenders care about whether the plan is accurate, realistic, and backed by numbers, not who typed it. A plan with invented statistics or vague forecasts will hurt you either way. Check every figure, cite your sources, make sure the forecast matches your real costs, and be ready to explain every number in your own words.
