The invention is directed to a budget planning system that improves the accuracy and predictability of budget planning within large organizations by enabling organizations to reconcile corporate financial models and organizational targets with detailed spending forecasts. A fitting has a tubular body with a connector portion adapted to sealingly connect the fitting to a device. The substrate has a reflective surface which blocks light leaving the light source from reaching the photodetector unless the light is reflected by an object external to the transceiver. The reports, and associated raw data, may be used as legal documents.
