Yes this would be a great feature, a discount sub-total at the grand total base of the invoice if applicable. Having a discount column on the invoice when only a small group of customers actually receive any discount is not beneficial to show zero to the others.
i totally support this request. can this be implemented please?
Quote/invoice/order/credit notes templates can be modified to include Discount amount. See fields below
QuoteTotalDiscount - Total Discount amount applied to Quote
SOTotalDiscount - Total Discount amount applied to Order
