Why become a Software as a Service Provider ?
A Software-as-a-Service provider is anyone that provides software services, via Internet, Intranet or Extranet, to software users. Becoming a SaaS provider can benefit a business that has dependent entities—such as franchisees or resellers—with which it has a strong business relationship, but poor IT process automation and information transfer.
A better IT relationship between the central business and its franchisees could raise the quality of services by improving information transfer and enabling certain processes to be automated.
By becoming a SaaS provider, the central business can host specialized applications for its franchisees, for business functions such as inventory control, accounting, promotions, loyalty programs, and so on—applications that franchisees around the world can access using only an ordinary personal computer and broadband connection.
This arrangement benefits all the parties in the relationship. Similarly, through the usage of these applications by the franchisees, the franchiser receives enhanced feedback and data that contribute to more accurate and valuable business intelligence. An enterprise might also consider becoming a SaaS provider if it has developed a valuable IT asset that could be monetized by providing it to other businesses.
