In one embodiment, a system for license management includes logic adapted for arranging entitlement slots under a plurality of licenses, each entitlement slot being configured for affording entitlement to use of an instance of a software application during a particular time frame, logic adapted for determining a license use signature from recorded license attribution information, logic adapted for receiving a notification of an instance not attributed to a license, and logic adapted for attributing the non-attributed instance to one of the plurality of licenses as a function of the license use signature, wherein each license has an entitlement value defining a maximum number of entitlement slots that may be attributed to that license during the time frame and any given instance of the software application may consume any number of the entitlement slots including zero entitlement slots.
