 An example of why dynamic discounting is beneficial to buyers is as follows.If a buyer receives a 2 per cent discount for early payment of an invoice—for example paying a 30-day-net invoice after 10 days.Therefore, instead of earning interest on the cash held in an account, it is “invested” for 20 days to get a 2 per cent return, This represents the equivalent of an over 36 per cent annual return on capital.
