Building a SaaS is harder than you think

Most SaaS projects fail not because of the idea, but because of poor execution. Agencies without SaaS experience underestimate the complexity of multi-tenancy, subscription billing, usage tracking, and onboarding flows. You end up with a prototype that can't scale.

Real-time metrics on MRR, churn, active users, and feature adoption. Export data, manage customers, and monitor system health from one place.
