The acronym SaaS stands for Software as a Service. It refers to a cloud computing model that delivers software applications over the internet. Rather than installing and maintaining software on individual devices, users can access SaaS applications through a browser. This model often includes features such as automatic updates, scalability, and reduced costs related to hardware and IT support. SaaS is commonly used for numerous business applications, including customer relationship management (CRM), collaboration tools, and enterprise resource planning (ERP), making it a flexible solution for organizations of all sizes.
