Patent ID: 8571907

Claim:
A non-transitory computer-readable medium storing computer program instructions for causing a computer device to implement a method for auditing invoiced weather-dependent work at a first location, the method comprising: locating a first weather information source providing weather information relating to a second location, the second location being estimated to have weather similar to weather occurring at the first location; determining a correlation between the weather information relating to the second location and a need for weather-dependent work at the first location by comparing weather history data relating to the second location from the first weather information source to work history data for weather-dependent work at the first location; and evaluating an invoice for weather-dependent work invoiced as being performed at the first location in light of weather data regarding the second location near the time of invoiced performance of the weather-related work at the first location to determine a likelihood that the weather-related work was necessary, based on occurrence of a trigger weather event or condition indicative of a need to perform weather-dependent work, and actually performed.
