Let us begin by looking at the potential pros and cons of software as a service. "The truth is, there are pros and cons of service software models. Weighed against the options of building or buying, renting software services might be a good decision. But before making the decision, ensure you're ready to exploit the pros and deal with the risks associated with the potential issues and cons."
"Potential Pros of Saas:
1. Automatic updates. You will always be getting the latest version of the software, with no work required. But these features are only valuable if you can leverage them to create value. Does your organization have the agility to improve processes and services, train users, and really get some value out of the upgrades?
2. Fewer compatibility issues. You'll have less to worry about in terms of compatibility issues. As long as you run a standard web browser, it's likely you'll be able to use the service.
3. No installs. You won't have to worry about installing the software on multiple machines or automating this with installation packages.
4. Small upfront costs. You'll be able to space payments out over time (regular monthly fees) and minimize the large upfront capital investments.
