Instead of buying software and then installing it, SaaS users subscribe to the software on a monthly or an annual basis. The relevant applications are used online through files saved in the cloud.

Since SaaS systems are cloud-based, they are easily scalable and can be quickly integrated with other similar systems. So telecom users don’t need to buy additional software or servers — only a new SaaS offering has to be enabled. Also, the SaaS provider effectively makes the server capacity available to the user.

SaaS apps can be accessed through the Internet and a number of mobile devices. The quality and consistency of user interfaces have also greatly improved in the past few years, and the adoptability learning curve is low.

The monthly or annual subscription fees paid by companies for using SaaS apps are much easier to budget for. SaaS systems often come with the flexibility to change or cancel the subscription.

Since SaaS-based data is hosted on the cloud and backed up by the provider, it is typically more secure than traditional systems. If there is a security emergency that hits the company server or an employee’s computer, most data remains secure on the servers and database of the SaaS provider.

Rather than purchasing software to install, or additional hardware to support it, customers subscribe to a SaaS offering. Generally, they pay for this service on a monthly basis using a pay-as-you-go model.
