When you purchase a SaaS solution, the only thing you get is functionality. And that is also the only thing you need. Why would you want your own server farm and your own management and maintenance department? You’d need to invest in this and would need IT specialists, and these are becoming increasingly scarce.
With a SaaS solution, whatever functionality you want is available immediately. Sometimes the application first needs to be configured. Sometimes you first need to import your own data or make a data exchange link with your other applications. But that’s all. After that, you can just start.
