Software as a Service (SaaS) is a software delivery model that provides customers with access to applications and data on demand. With SaaS, customers don’t need to install and run applications on individual computers or servers, instead they can access the software applications and data from any device with an internet connection. SaaS offers businesses a cost-effective and flexible way to access software applications and data, with benefits such as reduced costs, flexibility, scalability, and security. Popular SaaS services include email and collaboration tools, CRM, ERP, project management tools, and analytics and reporting solutions.
