Software as a Service (SaaS) is a business model where software applications are delivered over the internet on a subscription basis. Instead of purchasing and installing software on local computers or servers, users can access the software and its features through a web browser from anywhere with an internet connection.

Distributors are moving towards SaaS-based models of business for several reasons, including:

1. Lower upfront costs: SaaS-based models allow customers to access software applications without the need for expensive hardware or software installations, which can be a significant financial burden for businesses.
2. Scalability: SaaS-based models are highly scalable and can easily adapt to the changing needs of a business, whether that be an increase in users or the addition of new features.
3. Access from anywhere: SaaS-based models allow users to access software applications from anywhere with an internet connection, making it easier for businesses to collaborate and work remotely.
4. Automatic updates: SaaS-based models provide automatic updates to the software, which ensures that the software is always up-to-date and that users have access to the latest features and functionality.
5. Improved security: SaaS-based models typically have better security than traditional software models, as data is stored in the cloud and can be protected through encryption, access controls, and other security measures.

Overall, SaaS-based models offer a more cost-effective, scalable, and flexible approach to software delivery, which makes them an attractive option for distributors and other businesses.
