PAIN 01
PI says one thing, CI says another
The proforma invoice has 12 SKUs at one price. The commercial invoice arrives with 11 SKUs, two with different unit prices, and a packing list that doesn't match either. Your customs broker calls. The container is already on the water.
→ FIX: Trade Doc Engine reconciles PI, CI, packing list, and origin certificate against the PO before shipping and flags every mismatch.
