I am looking to determine the appropriate Net Working Capital target and unfortunately the Company is on a cash basis system. We've figured out how to deal with A/R relatively easily but A/P, Accrued Expenses and Prepaid Expenses seem fairly difficult. There are 150+ items and whether each is a prepayment, A/P, or Accrual and the terms for each is not tracked. Anyone have advice on how to calculate this and get something that is in the ballpark? Or alternative structures you've used?
