Turning an Idea into a Viable Business Model

Most businesses don’t fail because the idea was bad — they fail because the business model was never tested.

Turning an Idea into a Viable Business Model is the second book in the How to Start a Business: From Idea to Sustainable Income series by Douw Steyn.

This book takes you beyond inspiration and into disciplined thinking. You’ll learn how to:

• Tell the difference between a good idea and a viable business

• Define real paying customers (not just interested ones)

• Craft a value proposition that customers actually buy

• Choose and test the right revenue model

• Price for survival and growth (without underpricing)

• Understand costs, cash flow, and break-even clearly

• Prove viability with real-world signals before going all in

Written in plain language and grounded in South African business realities, this book is designed to reduce avoidable failure and help you make informed, confident decisions.

This is not a hype book.
It’s a thinking book — for people serious about building something that lasts.
