SaaS (Software as a Service)

Software sold by subscription.

SaaS (Software as a Service) is a software distribution model where the application is hosted in the cloud and accessible via internet. Customers pay a subscription (monthly or annual) rather than a perpetual license. This model generates predictable recurring revenue (MRR/ARR) and enables continuous product updates.

Concrete Example

Examples of SaaS: Salesforce, Slack, Zoom, Notion, CharliA.

Customers pay a monthly or annual subscription to access the service.

Tips
