Pre-shipment Sampling Customer Approval process

Hi All,

I have one requirement as-

When we send pre-shipment sample to Customer, at the time of delivery system creates Inspection lot & we record the results against that delivery. We print the Certificate, sample and certificate are send to customer.

Customer check the same sample in there Quality lab. Customer then approve the sample & their testing results send to factory.

I have to Capture their results in System.
