VSys Web Advanced allows your volunteers to register themselves online through a web portal, as well as view their job assignments, mandates and hours credited. You can also allow them to enter hours they worked off site and submit them to you for approval.
We host that site for you, in our dedicated datacenter, separate your VSys One database (whether that running in your own datacenter or ours).
VSys Web is entirely optional: you only use it if you want to provide access by volunteers to the system. All of the rest of VSys One's functionality and tools work great without VSys Web!
