Cash Flow Lessons I Wish Someone Had Taught Me at 30

Profit is an opinion. Cash flow is a fact. I spent the first decade of my career confusing the two, and I watched dozens of profitable businesses fail because their owners made the same mistake.

Small business owners are often surprised to learn that a business can be profitable on paper and still run out of money. It happens when revenue is recognized before cash is collected, when inventory builds up faster than it sells, or when growth outpaces the working capital available to fund it.

The three cash flow concepts every entrepreneur needs to understand are: operating cash flow (the cash generated by the core business), investing cash flow (cash spent on assets and equipment), and financing cash flow (cash from loans or equity). Most small business owners only look at their bank balance. That's not enough.

When I mentor entrepreneurs on finance, I start with a simple exercise: map out every dollar that comes in and every dollar that goes out over the next 13 weeks. Not revenue — cash. Not expenses — payments. The exercise is humbling for most people. It's also clarifying.

The goal isn't to make entrepreneurs into accountants. It's to give them enough financial literacy to ask the right questions of their accountants — and to recognize when the answers don't add up.
