We want to put in a specific discounted value, and have Sage work out the discount percentage. At the moment we can only input a percentage value and Sage generates the discounted value. We are having to calculate the percentage in Excel at the moment. Being able to put in a simple value you want the product to be when discounted, rather than trying to figure out a random percentage number would save lots of time.
Pretty sure this feature already exisits. Try Settings >> Invoice & Order Defaults >> Discounts. Then select the tickbox at the bottom Show Discounts on Main Invoice/Order Screen. This should add an extra column on your Sales Order or invoice for Discount £
