Hi there.  I also need to use the Sales Order option, which is not available, to track incoming orders and backorders.  I have just tried using the Estimate option (Changed the name to Estimate / Sales Order) and then invoicing from there. I now need to be able to print a report on these open quotes showing the backorders / items not yet invoiced and outstanding.  I cannot find / customise a report for this - perhaps you can assist?
