Fully agree. I'd add that great Product Managers should also have a deep financial intelligence.

Especially if you do not work for a big corporation, from the very beginning you must take care of your cash flow. Some Customers may have a standard payment period of even 90 days. Others will far exceed agreed deadlines. It’s common and expected.

Great Product Managers can mitigate these risks by, for example, agreeing monthly invoicing, advance payments or diversifying sources of income. They understand that companies need cash to survive, not its promise.
