Another company that does chargeback has just been pointed out to me:
There is interesting quote on this company's web site:
"Accurate and transparent chargeback is a key requirement in this age of cloud computing. By 2015, we forecast more than 50% of the Global 2000 will charge back most IT costs using service-based pricing, up from less than 10% today. New integrated tools will be needed to implement IT service-based chargeback."
