Not to be too trite, but the reason there’s not much is because there’s not much to say. If you’re using college math you’re making it too complicated. Cash flow is king. P&L tells you if you can survive for the first 1-5 years. Balance sheet tells you if it’s worth surviving for the next 5. For SAAS it’s the basic LTV, churn rate etc.... the guy who started salesforce has a nice pdf/book floating around that I’m trying to find. For solo consulting it’s lower your costs to bare minimum and then charge an hourly rate you can live on that assumes you work 40%-50% of the year. If you can’t find work at that rate you don’t have a business. Patrick Mckensie’s blog has nice info on raising rates once you’re started. But in general it’s all about cash flow when you’re bootstrapping. The best small business book I know of is Traction.
