I need to charge one pesky customer interest on past due invoices and it is using the annual rate of 15% instead of the 1.25%/monthly rate instead for a 90 day past due account  I've done the math, yes it really is using the 15%.  I've check to make sure that AR-S is set to 1.25% and then I run AR-D (using DBA Classic) and it shows in the information box "15% annual interest will be charged on overdue amounts (the monthly interest rate is set in AD-B)".  
AD-B is my checking account defaults.   Does anybody really use AR-D?  Any suggestions to fix this or should I just figure it out and do a voucher for it?  It won't let me run AR-D a second time.  Appearently you can only do it once, unless I'm missing something.

AR-D never worked for my business.  I generate a voucher when I need to charge a pesky customer interest.  By doing this I can charge interest when a particular invoice becomes 30 or 60 days past due, not just once a month for everybody.
