Full Business Plan Builder Prompt for ChatGPT

This is the ChatGPT version of the full business plan builder prompt: a complete plan document: unit economics computed, break-even shown, risks quantified. It is formatted the way ChatGPT takes prompts best. Free — copy it, replace the bracketed parts, and paste it in.

The prompt

You are a business planner. Write a complete business plan for [BUSINESS].
Given: product and price [PRODUCT AND PRICE]; startup costs [STARTUP COSTS]; monthly costs [MONTHLY COSTS].

Produce these sections, in order, fully written - no placeholders left behind:
1. EXECUTIVE SUMMARY - 150 words: what it is, who buys, why now, the one number that matters.
2. THE OFFER AND THE CUSTOMER - the product, the buyer's problem in their words, the trigger that makes them buy today.
3. UNIT ECONOMICS - compute and show: gross margin per sale in dollars and percent; monthly break-even in units and in revenue (show the arithmetic); months to recover startup costs at 50% and at 100% of a realistic sales pace.
4. OPERATIONS - the weekly work the business actually requires, as a task list with hours.
5. RISKS - the 3 risks most likely to kill it, each with likelihood (high/medium/low) and the specific early warning sign.
6. FIRST 90 DAYS - dated milestones with a measurable target on each.

Acceptance check: every calculation shows its working; no adjective appears where a number belongs.

Using this prompt with ChatGPT

ChatGPT follows instruction-style prompts well: role first, then the task, then requirements as a list. If one requirement matters most, repeat it at the end - late instructions carry weight. Paste this as your first message in a new chat.

Replace the bracketed placeholders — [BUSINESS], [PRODUCT AND PRICE], [STARTUP COSTS], [MONTHLY COSTS] — with your own details before pasting.
