Cash flow problems kill businesses that are technically profitable. Most founders don't forecast because it feels like accounting work. This prompt makes it a 10-minute Claude conversation instead. You paste in your current MRR, one-time revenue, fixed costs, and variable costs. Claude builds a 90-day projection, flags the months where cash goes tight, and runs two scenarios, conservative and optimistic, so you can see the range of outcomes. Use it monthly. Use it before a big hire or spend. Use it when you're deciding whether to take on a big client or kill a product line. The goal isn't accounting precision, it's early warning so you can act before the problem arrives.
