What does received short mean on an Amazon FBA shipment?

Amazon's fulfillment center counted fewer units of a SKU than the quantity you declared on the shipping plan. The difference shows as a negative number in the Discrepancy column of the shipment's Reconcile tab once the shipment is closed.

When can I file a claim for units received short?

Only after the shipment status is Closed and the Reconcile tab shows the shortage as eligible for investigation. Amazon keeps counting for a while after delivery, so an open shipment can still catch up. Once eligible, the current policy gives you a limited window — typically 60 days at the time of writing, confirm your marketplace's policy in Seller Central — so reconcile every shipment the week it closes.

What documents does Amazon ask for?

Two things: proof of ownership, usually the supplier invoice showing the SKU, quantity and your business name, and proof of delivery, the carrier's delivery confirmation or a signed bill of lading with carton count. Claims without both are routinely denied.

How much will Amazon reimburse for a short-received unit?

Since March 31, 2025, losses before a customer order are reimbursed at your manufacturing or sourcing cost, not the sale price. Enter your cost per SKU under Manage Your Sourcing Cost so Amazon uses your figure instead of its own estimate.

Inbound Shipment Received Short? How Amazon FBA Reimbursement Works (2026)

Last updated: September 2026

TL;DR: A shipment is "received short" when Amazon checks in fewer units than you sent. It is the loss type sellers reconcile least, because it hides inside a shipment that otherwise looks fine. The fix is procedural: open the Reconcile tab the week each shipment closes, keep the supplier invoice and the carrier's delivery proof for every shipment, and file within Amazon's window. Below is the exact path.

What received short actually means

Your shipping plan declared 120 units of a SKU. The fulfillment center's receive scan counted 112. Amazon's inventory now shows 112 sellable, and the shipment page shows a discrepancy of minus 8. Three things cause it:

A miscount at receive. Cartons scanned by weight or sampled rather than counted unit by unit. Amazon often finds the units later and the discrepancy closes on its own.
Damage or loss in transit that the carrier did not log. The carton arrives, the units inside are not all there.
A packing error on your side. This is why Amazon asks for proof of ownership: it wants to see that the units existed before it will pay for them.

Where to see it: the Reconcile tab

Seller Central, Inventory, Shipments (the shipping queue). Open the shipment.
Wait until the status is Closed. While it is Receiving or Checked-in, Amazon is still counting and the numbers move.
Open the Reconcile tab. Each SKU shows Shipped, Received and Discrepancy. A negative discrepancy is a shortage; a positive one is an overage.
For each shortage Amazon shows one of three states: investigation pending (Amazon is still looking, wait), eligible for investigation (you can file now), or closed with a reason.

The trap is timing. Reconciliation opens only after the shipment closes, and the window to file is limited. Since Amazon's 2024 and 2025 policy changes it is short — typically 60 days at the time of writing, confirm your marketplace's policy in Seller Central — so a shipment you forget for a quarter may no longer be claimable.

The two documents, and how to have them ready

Proof of ownership. The supplier invoice for the exact SKU and quantity, dated before the shipment, showing your business name. A pro-forma or a screenshot of a marketplace order page is often rejected. Keep a PDF per purchase order in a folder named by shipment ID.
Proof of delivery. For small parcel: the carrier's tracking page showing delivered, with the carton count. For LTL or FTL: the signed bill of lading with carton count and weight. Download it the day the shipment delivers; carrier pages expire.

If you cannot produce both, do not file. A denied claim with weak documents is harder to reopen than a claim filed once, properly.

Filing the claim

On the Reconcile tab, select the SKUs marked eligible and choose the reason that matches: Units were shipped but not received for a shortage.
Enter the quantity you are disputing. Claim the exact difference, not the whole line.
Attach both documents. Add one sentence: shipment ID, SKU, shipped versus received, and where the carton count appears on the proof of delivery.
Submit. Amazon replies in the case log, usually within days. Reimbursement posts to the Reimbursements report with reason Shipment to Amazon style codes.

Why these claims get denied

Filed too early. Shipment not closed, Amazon still receiving.
Filed too late. Past the claim window (typically 60 days — confirm your marketplace's policy in Seller Central).
Invoice does not match. Different quantity, different product name, no business name, or dated after the shipment.
Carton count mismatch. The carrier proof shows fewer cartons delivered than you declared; Amazon treats the loss as the carrier's and points you to a carrier claim.
Prep or labeling issue. Units received but unscannable are logged as problem inventory, not as short. Check the shipment's Problems section before assuming a loss.

What you get back

Since March 31, 2025 Amazon reimburses inventory lost before a customer order at your manufacturing or sourcing cost, excluding freight and duties. If you have not entered a cost per SKU under Manage Your Sourcing Cost in the Inventory Defect and Reimbursement portal, Amazon estimates it, and the estimate tends to be lower than a real invoice. Enter it once; it applies to every future claim.

Catching it without opening every shipment

The manual routine is: a weekly pass over every shipment that changed to Closed, the Reconcile tab, and a folder of invoices and delivery proofs. It is 15 minutes a week and it works. Limonene (limonene.app), an AI store manager for Amazon sellers, does the first half of that for you: it watches your inbound shipments and inventory ledger through the official SP-API, flags each shortage the moment it becomes eligible, and drafts the case text with the shipment ID, SKU and quantities filled in. Filing and the documents stay with you inside Seller Central. It works on Amazon.com, Amazon.co.uk, Amazon.de and 17 more marketplaces; the reimbursement totals it shows publicly today come from its first connected stores on Amazon.eg.
