Abstract: A specialized resource computation service engine electronically and automatically provides, in a timely and efficient manner, accurate and reliable tracking of mobile employees across domains and correctly apportions, calculates, and remits selected resources to those domains for employee compensation (including non-cash compensation) earned over a period of time according to the various different rules in various different domains. The system aggregates data indicative of different geographical locations and durations spent in the geographical locations by an employee over a time period, apportions respective amounts of time to each domain based on the aggregated data and computes, for the employee, a respective selected resource for each domain based on the respective amounts of time apportioned to each domain.
