With SaaS, software is centrally provided as a service through the Internet. Users create individual accounts and accruing costs are billed monthly or annually. The applications do not run on their own computer, but are called up online. The provider is directly responsible for providing, maintaining, and updating the programs. Users only need to access the software through a web browser. This usually works with any Internet-enabled device; all you have to do is log into the tool with your login data.
The most popular SaaS programs include project management apps, content management systems (CMS), financial accounting, file management, e-commerce, customer relationship management (CRM), archive management, and personal planning. While companies have often had to install multiple programs in the past and purchase and manage licenses for them, the much more customer-friendly SaaS model is becoming increasingly popular as a replacement.
