Money, pricing & model

How should I manage cash flow so my startup doesn't run out of money?

The short answer

Take your profit (and taxes) off the top before you touch the rest, invoice fast, and collect faster, cash timing kills more startups than lack of profit. The Profit First method flips the math: pay yourself and profit first, then run the business on what's left. Keep a buffer; being right about the future doesn't help if you're insolvent this month.
