Software-as-a-Service (SaaS) eliminates the need to install applications on the customer hardware. SaaS applications are typically accessed from a web browser and a single instance of the application often serves all the customers. Since the same application instance needs to fulfill different needs for different customers and there may be no option of creating a custom build for each customer, customizability of SaaS applications becomes an important aspect for delivering personalized software to the users. Customizability enables easy integration of the SaaS application with the customers existing systems and also empowers partners and resellers to easily configure the solution according to their and their customer’s requirements.
