Software as a Service (SaaS) is a great business model. Wikipedia defines SaaS as: software that is deployed over the internet and/or is made to run behind a firewall in your local area network or personal computer. With SaaS, a provider licenses an application to customers as a service on demand, through a subscription or a “pay-as-you-go” model. Saas is also called “software on demand.” SaaS was initially widely deployed for sales force automation and Customer Relationship Management (CRM). Now, it has become commonplace for many businesses tasks, including computerized billing, invoicing, human resource management, and service desk management.
