The Blanket Sales Orders & Releases system enables the easy capture or import of a new release and provides the necessary tools to manipulate the release and advise the customer of what has been accepted or changed, and why. It enables updating of existing scheduled orders automatically, and provides an audit trail of deliveries so that disputes over quantities supplied to date can be resolved. It also enables the various tasks to be subdivided so that the appropriate level of staff can be employed for each function.
