It is known by calculating average collection period that in what period an organisation recover the amount of borrow sale from debtors. This period should not be more than generally (1+1/3 of that). If average collection period is more than 4/3, than it is consider that there is more kindness in borrow conditions, carelessness and non-efficiency in managing credit collection. If recover period is less than 4/3, management efficiency, activeness and borrow conditions of business are satisfactory. Delay in recovery of credit is a sign of possibilities of debt accounts.
