Calculate interest on a series of debits and credits rather than a single amount, eg:
DATE DESCRIPTION AMOUNT BALANCE
18/09/2005 Invoice No. 16 $7,570.31 $7,570.31
28/09/2005 Payment -$6,973.91 $596.40
08/10/2005 Invoice No. 17 $7,990.37 $8,586.77
28/10/2005 Invoice No. 18 $8,694.09 $17,280.86
27/11/2005 Payment -$7,479.75 $9,801.11
This mode allows you to control whether interest is applicable to each item or not.
