VM2 UPS plugin:

Note:
In the past VM had these as free, the new VM2 still has the core as free but allow 3rd party plugins that are free and commercial this is still an on-going process and takes a little time to evolve.
With open source there is also the option to custom develop them.
Please note that for any commercial or free extensions, the vendor will support any internal issues.
I try to provide recommendations solutions, some solutions are a combination of free and commercial, but some of those solutions are new and/or untested.
