What Is SaaS Software?

Definition of SaaS Software

SaaS (Software as a Service) is a cloud-based software delivery model where users access software over the internet instead of installing it on their local computers or servers.

In simple words:
👉 You use the software online, and the provider hosts, updates, and maintains it.

Simple Example of SaaS

Instead of installing accounting software on your office server:

  • You log in through a browser

  • The system runs in the cloud

  • You pay monthly or yearly subscription

✅ That is SaaS software.
