Companies typically pay for more software than they need. They pay for products that are never or rarely used, they pay for premium editions when standard editions would have been sufficient and they pay for features that are not required.
LicenseMetrics makes it easy to compare what products are licensed, what products are installed and what products are actually used. LicenseMetrics shows how many users of premium edition products can be downgraded to standard editions by identifying Application Underutilization & Feature Underutilization.
