Here are Jeffrey's basic criteria to consider an application to be a true SaaS product:

Here are the key attributes which I use as a checklist to determine how true a vendor’s SaaS offerings are,
 
·         Networked applications
·         Enhanced user experience
·         Subscription pricing
·         Real-time analytics
·         Continuous enhancements
·         Self-provisioned, dynamic toolkits
·         Multi-tenancy preferred, but not required
