Our school is a fiscal year school. July 1 - June 30. Currently, families that has auto debit feautre on - the school cannot send a modified invoice for any additional charges after the 1st of the month due date. It is very important that we are able to send a modified invoices regardless of the families payment method for any "additional" charges. Right now, the ST parameter restricts us to invoices or notify the family that they have additional charge. Please work on this parameter restriction to enable us to send invoices or modified invoices to all families regardless of their payment method. Thank you
