• Software as a Service (SaaS) is a software licensing model that allows you to access software on a subscription basis using external servers.

  • SaaS allows each user to access programs over the Internet, instead of having to install the software on the user’s computer.
  • SaaS has many business applications including file sharing, email, calendars, customer retention management, and workforce management.
  • SaaS is easy to implement, easy to update and debug, and can be less expensive (or at least have lower upfront costs) because users pay for SaaS as they go rather than buying multiple software licenses for multiple computers.
  • Disadvantages of SaaS implementation are related to data security, speed of delivery and lack of control.
