In the fast-paced world of Software as a Service (SaaS), measuring performance is not optional—it’s critical. SaaS businesses rely on recurring revenue models, and understanding key performance indicators (KPIs) is essential for growth, retention, and profitability. In this guide, we’ll explore everything you need to know about SaaS KPIs, how to calculate them, and why they matter for your business.
