Small Software, Real Money: How to Run a Profitable Micro-SaaS for Hundreds of Customers

You do not need a million users. You need enough of the right customers at a price that covers every obligation your software creates. A working product is only the beginning. Small Software, Real Money shows how to turn a narrow software tool into a controlled, durable business designed for hundreds of customers rather than millions. Work backward from the income you need. Set a customer ceiling. Calculate contribution by plan. Price support, hosting, payment fees, AI usage, refunds, and failure months before they erase the margin. Decide which features earn their cost, which customers create concentration risk, and which growth channels can actually reach your finite market. You will build practical systems for scope control, onboarding, support, backups, recovery, retention, churn analysis, acquisition, and monthly operating decisions. Worksheets and decision cards help you choose when to maintain, raise prices, pause growth, hire, sell, or close. This book is for solo founders and small teams who want recurring revenue without building a venture-backed company around it. Build software that pays well, stays understandable, and does not become a larger job than the one it was meant to replace.
