So many features... It will take some time to decide which and how I'll deploy to fully customize VPS billing, but things went well during the trial.
Gotta be able to allow customers to manage DNS directly, so this module appears to be an effective solution. Will be great to outsource DNS Hosting to CloudFlare or other.
I'll be making use of this module to auto-issue Plesk licenses on Virtuozzo VPS, thus using that module as well. Things went well during the 7 day trial!
There was a bit of a learning curve in comparison to the system we used previously, but this module integrates well with Virtuozzo VPS and Plesk modules that we are also using, so it is an effective solution to our need for dynamic IP Address management.
Switching over from OBAS to WHMCS with Virtuozzo VPS module was successful and when used along with the IP Manager module, it appears to be an effective solution, allowing me to continue using Virtuozzo.
This module made things MUCH easier for me in showing a retail price with strike-through, and then the discounted price beside, as well as, temp adjustment of price for multiple products at once. Works great!
