Proof Before You Start a Business is a practical guide for anyone thinking about starting a small business with their own savings, family money, or limited capital.

Instead of focusing on motivational success stories, this book asks the questions that matter before you spend your money: How much will the business really cost? How many sales do you need every day? How long can you survive without making a profit? And when will your money actually run out?

The book takes you through demand testing, break-even calculations, cash flow, location, franchises, startup costs, family funding, getting paid, bookkeeping, taxes, hiring, and knowing when to stop. It is built around simple calculations and practical exercises that can be completed with real numbers.

The central idea is simple: prove the business before you commit everything to it.

Whether you are planning a shop, restaurant, service business, manufacturing unit, online business, or another small venture, this book helps you replace assumptions with evidence and enthusiasm with a clear financial picture.
You may discover that your idea needs to change. You may discover that you need more capital. Or you may discover that the numbers actually work.

Either way, you will know before you have spent everything.

The book's approach is deliberately practical: test demand, understand the economics, know your runway, and make the decision based on evidence.
