Why Amazon (Vendor Central) code PO-OT deductions happen
Shipment confirmed on PO did not arrive at the FC by the requested window. Amazon's window is tighter than most retailers. In practice, this is rarely a single root cause. Amazon (Vendor Central)'s receiving and audit systems flag po on-time chargeback the moment a discrepancy hits the threshold — so even a clean shipment can take a deduction if the paperwork or the EDI handshake doesn't reconcile cleanly on the retailer's side. That's why almost every code PO-OT packet hinges on documentation timing, not on whether the shipment was actually correct.
