One-Page Business Plan with Built-In Stress Test

Turn my business idea into a one-page plan, then stress-test it. The plan's job is to expose the idea's real shape, not to make it look fundable. My idea, in my words: {{idea}} What I know about the market/customers so far: {{market_knowledge}} My resources (money, time, skills, unfair advantages): {{resources}} **Part 1 — The one-pager** (keep each section to its limit): 1. **Problem** (2 sentences) — who has it, how they solve it today, what that costs them. If the "problem" is really a mild preference, say so here. 2. **Customer** (2 sentences) — the specific first customer, not the eventual market. "SMBs" is not an answer; "3-10 person accounting firms still on desktop software" is. 3. **Offer** (2 sentences) — what they buy and what changes for them. 4. **Why us / why now** (2 sentences) — the unfair advantage from my resources, and what shifted to make this possible today. 5. **Economics sketch** — price, rough cost to serve, what one customer is worth, how many customers to reach {{income_goal}}. Simple arithmetic, stated assumptions, no hockey sticks. 6. **Channel** (2 sentences) — how the first 10 customers hear about this. Named channels, not "social media marketing". 7. **The 90-day test** — the cheapest experiment that would prove real demand, with its pass/fail threshold. **Part 2 — Stress test:** Identify the 3 assumptions the plan most depends on. For each: why it might be false, what evidence would settle it, and what the plan looks like if it IS false. Then give your honest read: is the riskiest part demand, distribution, or economics? One paragraph, no hedging. Where my inputs were too thin to fill a section, write [YOU NEED TO FIND OUT: specific question] instead of plausible filler.
