A practical, section-by-section guide — with real prompts — for anyone who's been putting off writing their business plan because they don't know where to start.
Most business owners who need a business plan either pay a consultant thousands of dollars or stare at a blank page for weeks. There's a third option: spend a weekend with AI and walk away with a real first draft.
This guide walks through every section of a standard business plan — what goes in it, why it matters, and the exact prompts you give an AI to help you write it. No business school required. No consultant fees.
You'll still need to provide the facts (your numbers, your market, your idea). The AI handles the writing, the structure, and the "how do I even say this" part. Think of it as a very fast, very patient business writing partner.
What you need: A free ChatGPT or Claude account. About 4–6 hours spread across a weekend. A basic understanding of your own business. That's it.
The executive summary is a 1–2 page overview of everything in your business plan. It's written last but placed first — it's what a bank or investor reads to decide if they want to keep reading.
What it covers: What your business does, who your customers are, what makes you different, how you make money, and what you're asking for (if anything — a loan, investment, etc.).
Your job first: Answer these in plain sentences before using the prompt below:
"Write a 2-paragraph executive summary for my business plan. Here's the information: [paste your 5 answers]. Make it sound professional and direct, like something I'd give a bank. Don't use buzzwords or hype — just clear facts."
After AI writes it: Read it out loud. Change anything that doesn't sound like you. The AI version is a starting point, not the final word.
This section explains what your business is, what industry you're in, what you sell, and how you're structured (sole proprietorship, LLC, etc.). It's the "just the facts" section.
What it covers: Your business name, location, legal structure, when you started (or plan to start), what products or services you offer, and your mission in 1–2 sentences.
"Write a business description section for my business plan using this information: [paste your facts]. Include: what the business does, what we sell, our legal structure, and a mission statement. Keep it factual and easy to read — no filler."
This section shouldn't be long. Half a page is usually plenty. If AI makes it longer, ask it to cut it down: "Shorten this to the essential facts only."
This is the section most people skip — which is exactly why it makes your plan stand out when you include it. It shows you understand your industry, your competition, and your customers.
What it covers: How big is your market? Who are your competitors? Who exactly are your customers and what do they care about?
"Write a market analysis section for my business plan. My business is [describe it]. My main competitors are [list them and what you know about each]. My target customer is [describe them]. The market I'm in is [describe it]. Help me structure this into a clear market analysis with a competitor overview and customer profile."
Then ask: "What questions should I be answering in a market analysis that I haven't addressed yet?" AI will point out gaps you can fill in.
This section is where you explain what you're actually selling in more detail — and why customers would choose you over the alternatives.
What it covers: What you sell, how it's priced, what makes it different from what's already out there, and how you deliver it.
"Write a products and services section for my business plan. Here's what I offer: [list your offerings with prices and descriptions]. My competitive advantage is [explain it]. Make it clear and compelling — no exaggeration, just explain why it's good and who it's for."
Avoid AI hype in this section. If the output says things like "industry-leading" or "revolutionary," ask AI to remove the superlatives: "Rewrite this without any sales hype or exaggerated claims."
This section answers: How do people find out about you, and how do you turn them into paying customers? Banks and investors want to know you have a plan to actually get customers — not just that you've built something.
What it covers: Where you'll market (channels), how you'll attract leads, how you'll convert them to customers, and roughly what you'll spend.
"Write a marketing and sales strategy section for my business plan. My main marketing channels are [list them]. A typical new customer finds me by [explain the path from discovery to purchase]. My rough marketing budget is [amount or 'mostly organic for now']. Include a short section on customer retention. Keep it realistic and specific — no vague plans."
Be honest here. "We will use social media, SEO, and word of mouth" is more credible than "We will run aggressive multi-channel campaigns." Specific and honest beats ambitious and vague.
This section explains how your business actually runs day to day. It's less exciting than the vision stuff — but it proves you've thought through the practical side.
What it covers: Where you operate, who does what, key suppliers or partners, and how you deliver your product or service.
"Write an operations plan section for my business plan. My business operates from [location]. The team is [describe people and roles]. My key tools and suppliers are [list them]. Here's how we deliver our service from start to finish: [describe the process]. Keep it practical and clear."
This is the section most people dread. The good news: AI won't do the math for you — that's your job — but it will structure your numbers into a professional format and help you think through what you might be missing.
What it covers: Revenue projections (how much you expect to make), startup or operating costs, and when you expect to break even.
"Help me write the financial projections section of my business plan. Here are my numbers: [paste your revenue estimates, costs, and break-even calculation]. Turn these into a clear financial narrative — a paragraph explaining the numbers, then a simple table summarizing Year 1 projections. Assume I'm showing this to a bank."
AI is also great for sanity-checking: "Here are my projected costs and revenue — do these numbers look realistic for a [type of business]? What am I probably forgetting?"
Once you have all seven sections drafted, your plan needs to read as a single cohesive document — not seven separate prompts stapled together.
"Here is my complete business plan: [paste it]. Please review it for: (1) inconsistencies between sections, (2) vague claims without supporting detail, (3) anything that sounds like filler rather than real content. Give me specific suggestions, not general feedback."
AI is a writing partner — it helps you structure, phrase, and polish. It cannot invent real numbers, verify your market assumptions, or guarantee your plan will get approved for a loan.
The facts have to come from you. If you put in vague or made-up information, you'll get back a polished-sounding plan built on sand. Banks and investors are good at spotting that.
Use AI to move faster and write better. Do the actual thinking yourself — that's the part nobody can do for you.
