The Big Idea

Most business owners and investors look at financial statements and see numbers. What they’re actually looking at is a story — and they’re reading it wrong. Every business runs on three documents: the Income Statement (are we profitable?), the Balance Sheet (what do we own and owe?), and the Cash Flow Statement (do we have cash to survive?). Thomas Ittelson’s core argument is that these three are not separate reports — they are one mathematically connected system. The moment you understand how they link, you stop confusing profit with health, and you start seeing what the numbers are actually saying.
