No / A central element in developing credit management policy involves design choices on the extent to which credit activities are best managed internally or through specialist market intermediaries. This paper draws on the findings of a survey on the credit management practices and policies of large UK companies to: (1) Examine the type of firm most likely to enter into specialist external credit management structural arrangements; and (2) Identify contextual and credit policy choices influencing the credit period taken and late payment of debts. The study found that specialist intermediaries are not particularly common in large firms. The paper also identifies a number of contextual and policy variables that help explain variation in debtor days and late payment by customers.
