charge late fee
It would be great to be able to charge a late fee automatically to invoices that are past due (and have this be an option on each invoice). For example, we charge a $15.00 late fee for all tuition not paid by the 15th of that month. It would be nice to set our recurring tuition invoices to generate a $15.00 late fee when the invoice is not "paid" by that date (so by the 16th or whatever).
This is still something that is planned, but there is a high degree of complexity around the fine details on how this should function.
