Add Interest Charge on an Invoice

Q:  I need to charge a client interest for past due amount.  How would I do this?  As a Time/Fee?  But I don’t want it to include tax.

A:  if you enter the charge as an “Expense”, you can make the Expense “Exempt” from tax.  You can then put the charge to an income GL when it is paid.
