Using AI to write a business plan: a real example
Want to start a small business but the business plan scares you? It happens to everyone. The blank page freezes you. You don't know where to start, so you keep putting it off. Here I show you a real case, step by step. We follow Mark and his small café. You will see how using AI to write a business plan works from start to finish. No theory: just what to type and what to do.
The starting idea
Mark wants to open a small bistro in the suburbs. He has a $30,000 budget. He has no idea where to begin. First thing: he tells the AI who he is and what he wants to do. The more details you give, the better the answer. If you write little, the AI guesses. If you write a lot, it builds a plan that fits you.
His first message is simple and clear:
- "I'm Mark, I want to open a bistro in the suburbs of my city."
- "I have $30,000. Target: local families and workers."
- "Help me build the business plan step by step."
Step 1: the project summary
Mark asks the AI to write the executive summary. It's the short part that opens the document. In ten lines it explains the idea, the target and the goal. It's the part the bank reads first.
The AI gives him a clear text. Mark reads it and fixes two things: the name of the place and the opening hours. It takes two minutes. Before, it would have taken him an hour. A useful prompt: "Rewrite the summary in simpler words, no jargon."
Step 2: the market analysis
Now he needs to understand the competition. Mark asks: "What are the weak points of the cafés in my area? How can I stand out?"
The AI suggests concrete ideas: a fixed lunch menu, local products, a kids' corner. Mark doesn't have to accept everything. He keeps the ideas he likes and drops the rest. The AI proposes, he decides. Then he refines: "Give me three things a small café can do that a chain can't."
Step 3: the numbers and costs
This is the part that scares people the most. Mark gives the AI his real data: $1,300 rent per month, two employees, suppliers. Then he asks it to build a monthly cost table. Important: he uses real numbers, not made-up ones.
- Fixed costs: rent, salaries, utilities.
- Variable costs: raw materials, supplies.
- Expected revenue: covers per day times average ticket.
Careful: the AI numbers are only a draft. Mark checks every figure with his accountant. The AI builds the structure, it does not replace an expert. A handy prompt: "Give me three scenarios: bad, normal, great."
Step 4: the break-even point
Mark wants to know how much he must earn to avoid losing money. He asks the AI: "With these costs, how many customers a day do I need to break even?"
The AI does the math and explains the reasoning. Mark learns he needs about 60 covers a day. Now he has a clear goal. This number helps him decide if the idea holds up. If 60 covers feel like too many, he changes the menu or the price before he opens.
Step 5: putting it all together
In the end Mark asks the AI to join all the pieces into one clean document. Summary, market, costs, revenue, break-even. The AI gives him a tidy text to bring to the bank for a loan.
Total time: one afternoon. Without AI it would have taken weeks. And most of all: now he understands every part of his plan, because he built it himself with the AI's help. When the bank asks questions, he can answer. That matters more than a perfect document.
Mistakes to avoid
Three common traps when you use AI. First: don't paste the numbers without checking them. Second: don't trust made-up market data, look it up yourself. Third: don't ask for everything in one message. Go step by step. One block at a time. That way the plan stays clear and you really understand each part.
