Negative Invoice Amounts/Add Discounts to Invoices

Richiesta

When viewing a generated invoice, please make available the ability to add negative lines in to the invoice. EG. Description "Payment Method Discount" Value "-1.32" As this is a negative value item, it will be subtracted from the invoice total (or added as a negative) thus reducing the invoice total (before tax) by the amount specified. This is so important for showing clients discounts that are applied after invoice generation.
