I have a fairly complicated joomla site and a WHMCS site, each with different ip's, but JWHMCS runs this flawlessly. I had the installation service ordered and paid for, and that alone was worth all the money. Because I wanted to post some specific parts made me think that this would cost extra, but the guys at GoghiherIS placed these extra parts without charge.
I’m very satisfied with this product and service, many other companies can learn from this.
They just give you that bit extra..
