What is SaaS?
Definition
SaaS (Software as a Service) is cloud-based software delivered over the internet on a subscription basis with no local installation.
How Does the SaaS Model Work?
In SaaS, software is not installed locally; it's accessed via browser or mobile app. The provider is responsible for infrastructure, updates, and security.
- Subscription pricing — monthly or annual, no upfront capital
- Automatic updates — new features available immediately
- Flexibility — user count and plan adjust to your needs
- Accessibility — work from anywhere with internet
Unlike on-premise software, SaaS is a spend model rather than a capital investment; in accounting, it's booked as OPEX.
