Why Amazon FBA Shipments Go Missing, and Why It Matters
Imagine shipping 13 pallets across the country, watching your carrier deliver them with a signed proof of delivery from an Amazon fulfillment center, and then logging into Seller Central to find the shipment marked CLOSED with zero units received. No receiving error. No discrepancy flag. Just silence.
This is exactly the situation thousands of FBA sellers face every year. Amazon's fulfillment network processes millions of inbound pallets weekly, and the sheer scale means units do get lost, miscounted, or stranded between receiving docks and inventory systems. According to Amazon's FBA lost and damaged inventory policy, Amazon is liable for items lost or damaged within its fulfillment network, but only if you follow the correct reconciliation and claim process within the required timeframes.
For the seller in this story, the stakes were high: 2,327 units worth more than $80,000, shipped as an LTL freight load, confirmed delivered, but not a single unit reflected in inventory. The shipment was closed. The support case sat untouched for ten days. Every hour without a resolution meant real carrying costs, lost sales velocity, and a growing risk that the reimbursement window would expire.
Understanding exactly how to fight back is not optional. It is the difference between recovering your inventory value and absorbing a loss that could cripple a seasonal business.

How Amazon's Shipment Reconciliation Process Actually Works
Before you can demand reimbursement, you need to understand the sequence Amazon uses to process inbound shipments, because knowing where the breakdown occurred shapes every document you submit.
When a carrier delivers an LTL shipment to an Amazon fulfillment center, the receiving team is supposed to scan each box or pallet label upon intake. Those scans generate receiving events that feed into your Shipping Queue inside Seller Central. If no boxes were scanned at all, the system shows zero received and, critically, marks the shipment as having no reconcilable discrepancy, because from Amazon's perspective, nothing arrived to create one.
This is the trap. A shipment that was physically delivered but never scanned into the system shows a clean status rather than an error status. The seller sees "no problems found" while their entire shipment is invisible to inventory systems. Reconciling through the standard workflow is blocked because there are no scanned boxes to measure against.

This is a known failure mode, and it requires a different escalation path than a standard short-shipment dispute. You need to push the case through a manual investigation tied to your proof of delivery documentation rather than waiting for the automated reconciliation workflow to surface the problem on its own. The general framework for FBA reimbursement claims covers how Amazon categorizes these losses internally.
The Paper Trail That Wins Reimbursement Claims
FBA reimbursement cases live or die on documentation. Amazon's investigative teams are evaluating one core question: did the seller's inventory enter Amazon's custody? Every document you provide should answer that question directly.
Here is the evidence set that typically resolves cases at this scale:
- Bill of Lading (BOL) — showing the shipment origin, Amazon destination FC, and unit/pallet count
- Carrier Proof of Delivery — signed by the Amazon FC receiving dock, with timestamp and employee signature
- Packing List — itemizing every FNSKU, unit count, and box weight for the shipment
- Shipping labels and box content files — uploaded to the original shipment in Seller Central before the shipment was created
- Carrier tracking history — showing continuous transit from your warehouse to the Amazon FC
- Freight invoice — confirming the LTL booking details and delivery confirmation
- Photos from the FC shift supervisor — if you can obtain them through your account representative, attach them to the case as direct FC-side confirmation of physical receipt

For the seller in this story, the photos and internal confirmation from the FC shift supervisor were potentially the strongest piece of evidence in the file. That documentation proves the pallets were physically present at the facility, which directly contradicts any claim that the shipment was never received. It narrows the dispute to an internal scanning or routing failure, which falls squarely within Amazon's liability under its own policy.
The FTC's guidance on commercial documentation supports a broader principle: when you have contemporaneous records establishing delivery and custody transfer, the burden of proof shifts to the party claiming non-receipt.
How to Write a Reimbursement Demand Letter Amazon Cannot Ignore
A support case number alone will not move a reimbursement claim at this scale. You need a formal, policy-referenced demand letter submitted to the case that forces Amazon's investigation team to engage with your evidence rather than issue generic replies.
This is where many sellers lose ground. They follow up with messages like "any update?" or "please help" instead of structured demands that cite specific policy obligations and attach indexed evidence. An effective reimbursement demand letter does several things at once: it establishes the timeline of your shipment, cites Amazon's own liability policy, references each piece of supporting documentation by name, and requests a specific outcome with a specific deadline.
The Appeal Letter Generator inside AppealsPro.ai is built for exactly this kind of escalation. When you paste your shipment details and the text of Amazon's case responses, it generates a policy-specific demand letter that maps your evidence to Amazon's stated reimbursement obligations under their FBA lost inventory guidelines. The output reads as a professional, structured demand rather than a support plea, which is the register that gets routed to senior investigation teams instead of front-line agents.

For a case involving $80,000 in inventory and 2,327 units, the difference between a well-structured letter and a vague follow-up message is not a minor detail. It is often the entire case.
"At the scale of a five-figure inventory loss, sellers are no longer dealing with routine support workflows. They are effectively in a commercial dispute resolution process, and their written communications need to reflect that reality. Precision in language, specificity in evidence citation, and firm but professional tone are what move cases from limbo to resolution." — Marlena Voss, Senior E-Commerce Claims Strategist, Hightower Commerce Advisory
How to File an FBA Reimbursement Claim Step by Step
The following procedure covers an LTL shipment where zero units were received and the shipment has been closed.
- Gather all carrier documents before opening or escalating any case: bill of lading, signed proof of delivery, packing list, and box content upload confirmation from Seller Central. Organize these into a single numbered document set you can reference by exhibit number in your letter.
- Log into Seller Central and navigate to the shipment in your Shipping Queue. Take a screenshot of the shipment summary showing the CLOSED status, zero units received, and the "no problems found" status line. This screenshot is your baseline evidence that the reconciliation tool is blocking normal dispute resolution.
- Open a new case under the FBA category for lost shipments, or escalate your existing case by submitting a formal written demand as a case reply rather than a conversational follow-up. Attach all documents in the order you reference them in your letter.
- Draft your demand letter using the structure: (a) shipment identification and timeline, (b) Amazon policy citations establishing liability, (c) evidence index with exhibit references, (d) specific reimbursement amount calculated at Amazon's standard replacement value formula, and (e) a response deadline of seven business days.
- Use the reply analysis workflow in AppealsPro.ai after any reply arrives from Amazon. Paste the response text and the tool will identify whether Amazon has acknowledged liability, requested additional documentation, or issued a denial, and it will recommend the precise next-step language to move the case forward.
- If the case does not advance within the seven-day deadline you set, escalate through Amazon's Seller Performance contact channel and reference your case ID, the evidence on file, and the elapsed timeline. Mention the signed FC proof of delivery explicitly, as this is the single most compelling data point for routing the case to a senior team.
- If escalation through standard channels fails, consider filing a reimbursement request via the FBA inventory reimbursement form and, if applicable, submitting a claim under your cargo insurance policy in parallel so your timeline for insurance recovery is not delayed by Amazon's investigation.
Why Cases Like This Stall: The Silent Queue Problem
One reason reimbursement cases at this scale sit untouched for ten or more days is that Amazon's support routing relies heavily on automated triage. Cases that lack standard discrepancy flags, such as a shipment that shows no receiving events at all, often fall outside the automated escalation criteria and land in a queue that requires manual review routing.
Sellers cannot fix this from the outside. What they can do is force a routing change by making the case file dense enough with documentation and clear enough in its legal framing that a human reviewer recognizes it as a priority dispute rather than a routine inquiry.
If you have gotten this far into a stalled case, you already know how much a week of silence costs when your Q4 inventory is sitting in a fulfillment center that has no record of receiving it.
For a seasonal seller who shipped 2,327 units in anticipation of Q4 demand, every additional day the case sits unresolved is a compounding loss: the inventory is unavailable to sell, the reimbursement is not in the account, and the peak selling window is closing. Professional-grade documentation is not just helpful in that situation. It is necessary.
