Inbound Shortage
When Amazon receives fewer units than you shipped to FBA — eligible for reimbursement, with a manual claim window of 60 days from delivery under Amazon's current US policy.
An Inbound Shortage occurs when the quantity of units Amazon records as received from your inbound shipment is less than the quantity you actually shipped. This is one of the most common reimbursement opportunities, and one of the most under-claimed because it requires reconciling each shipment line by line.
Common causes: units lost during the unloading/check-in process, miscounts at receiving, units that fall behind conveyors, units redirected to the wrong fulfillment center. Amazon used to be very lenient about reconciling inbound shortages automatically; their auto-reimbursement coverage has tightened in recent years, putting more burden on sellers to file manually.
Filing deadline: 60 days from the shipment delivery date — Amazon shortened this from the former 9-month (270-day) window, so reconcile shipments promptly. Required evidence: the original shipment plan with declared quantities, carrier proof of delivery, and any photos or pack lists you have. SellerVault's reimbursement engine cross-references every inbound shipment line against received quantities and surfaces shortages with the evidence packet pre-attached.
