How to Create a Business Plan With ChatGPT

Updated 7 October 2026 · ModernExpert.AI editorial team

Quick answer

To create a business plan with ChatGPT, set up one project or long conversation with your business context, then work section by section: ideas, customers, competitors, model, marketing, sales, operations and financials. Ask it to mark facts that need sources, and verify them before using the plan.

Set up the context once

Start with a context message describing your business, location, budget, goals and audience for the plan. In ChatGPT, using a Project or custom instructions keeps this context available across conversations, so you don't repeat yourself.

Ask ChatGPT to interview you first: 'Ask me 15 questions before we start.' Your answers make every later section more specific.

Work section by section

Draft one section per conversation turn and review it before moving on. For research-heavy sections, use ChatGPT's web search so it can cite sources, and open each link to check it says what ChatGPT claims.

Use file uploads

Upload documents you already have — interview notes, competitor price lists, supplier quotes — and ask ChatGPT to use only those for a section. This is more reliable than relying on its general knowledge.

Financials with data analysis

ChatGPT can create spreadsheets and run calculations. Give it your assumptions and ask for a downloadable forecast with formulas. Open it in your own spreadsheet software and check every formula.

Privacy

Check your data settings and avoid pasting sensitive personal data or confidential financial information unless your plan's terms allow it. Business and team plans typically offer stronger data controls.
