Short for Software-as-a-Service, SaaS is a web-based method of delivering software applications and functionality over the internet through a browser. Customers of SaaS have the advantage of not needing to install and maintain local software, as they use the software rather than own it. Because it is web-based, SaaS can be available 24/7 from any station that has access to the internet.

The ePortal site on the eBridge web site function as an SaaS model that allows for the remote access and tracking of business transactions.
