The PartsWatch mobile application is an extension of the PartsWatch desktop POS application, which is used within the automotive aftermarket industry by part stores who buy and sell auto parts. PartsWatch mobile allows a store owner or manager to see their store sales from their iOS device. In addition, PartsWatch mobile enables store users to scan a Vehicle Identification Number (VIN) on a car or truck to transmit the year, make, model, and engine of the vehicle to the PartsWatch desktop application running in the store so that electronic catalog lookups can be performed to find parts for that vehicle (e.g. rear brakes).
