Cash Flow vs. Profit: What's the Difference?
HBS Online · Harvard Business School Online (YouTube) Free Beginner
If the difference between revenue and cash in the bank still feels fuzzy, a short visual walkthrough makes it click faster than any spreadsheet. This one keeps it plain for founders without a finance background: revenue is what you have earned on paper, cash flow is what has actually moved through your account. That single distinction is what stops the confusion in the question.
- Revenue is booked when you deliver, not when the customer pays, so a profitable month can still leave your account empty.
- Cash flow tracks the timing of money in and money out, which is what really keeps the lights on.
- A business can be profitable and still run out of cash if payments arrive late.
