There is no definitive answer to this question since it can mean different things to different people, but in general, SaaS or HCM refers to software as a service, which is a type of subscription software that allows users to access and use the software from a remote location. This can be done via the internet or a private network.
There are many benefits of using SaaS or HCM, including the fact that it is generally much more affordable than traditional software since you only pay for what you use, it is easy to scale up or down as your needs change, and it can be accessed from anywhere with an internet connection.
