Invoices - Edit Installment Plan
Editing installment plans is only applicable with Invite Based Registrations for active invoices where at least one installment has been paid.
Note, the due date of remaining future installments can be changed. If there is more than one future installment, if an installment is deleted, the payment amount is equally distributed to the remaining future installments.
Past due installments can be edited even in the case of failed payments.
