Definition: SaaS, or Software as a Service, is a cloud-based software delivery model where users access applications via the internet, typically through a subscription. Instead of purchasing and installing software on individual devices, customers pay for ongoing access to centrally hosted platforms—usually maintained and updated by the provider.
SaaS solutions are used across every industry, offering flexibility, lower upfront costs, automatic updates, and scalable access to software tools.
Use It In a Sentence: Our startup switched to a SaaS CRM platform to streamline client communications and reduce IT overhead.
