A Business Book for People Who'd Rather Not Read One
This isn’t accounting theory. And it’s not a how-to guide for spreadsheets. It’s the book every business owner wishes they had before they started making financial decisions in the dark.
Through the lens of a fictional donut shop, this book walks readers through five years of growth—from concept to operations to financial turning points—without ever getting buried in jargon, debits, or textbook math.
Each chapter introduces a real business challenge and the accounting logic behind how to solve it. It’s not about doing the accounting. It’s about understanding how it works—so decisions get better, not just bigger.
If you’re an entrepreneur, founder, or just someone who wants to learn what the numbers actually mean, this book was written for you.
