[1] The procurement department or an external expeditor controls the progress of manufacturing at the supplier concerning quality, packing, conformity with standards and set timelines.
These are experts from companies specializing in this field who keep track of the deadlines, supervise progress on site and check whether the components are properly packed.
In this way, the supplier secures his liquidity as he is paid immediately when the components leave his factory (letter of credit) and the customer/bank knows that the goods will be delivered correctly.
Field expediting provides clients with a comprehensive review of the precise standing of their order and any on site action to rectify any potential problem areas.
