USL has had a long-standing relationship with Peter Baker Transport (PBT) which has allowed us to develop and implement a number of processes to ensure that both USL and PBT meet required service levels.
We measure the achieved service level on a daily basis. The measure is taken from the time an order is released into our warehouse management system to the time it is dispatched.
PBT service level is measured from the time the shipment is ready to be dispatched to the time the end user acknowledges receipt of delivery.
The table below indicates USL/PBT service level targets for USL’s current business requirements:
