CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is Lag financing cost = earned unbilled revenue × annual funding rate × lag days ÷ 365, evaluated from Average earned unbilled revenue, Average billing lag days, Annual working-capital rate (%), Billing cycles per year to produce Annual financing cost of billing lag. This isolates submission delay; customer approval and payment delay should be analysed as additional collection stages. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.
The decision this tool supports
