Overcoming the FBA 'Investigation Completed' Wall

An “Investigation completed” result is a decision to examine with evidence, not proof that an automated system ignored your shipment. Escalate a specific discrepancy through the applicable support route.

Editorial review: October 23, 2026

Removed advice to bypass case routing, unsupported rejection percentages, and claims that shipment weight proves Amazon lost particular units.

Understand the Shipment Status

Amazon’s reconciliation guidance says an investigation-completed status means units were physically counted at receipt. Compare that result with your dispatch records, later receipts, and reimbursements. A delivery signature confirms delivery of a consignment; it does not prove the contents of each carton.

Build a Reconciliation That Can Be Checked

  1. List planned and received quantities by SKU/FNSKU and carton.
  2. Match carton labels and tracking references to the shipping plan.
  3. Attach the required ownership documents and carrier evidence.
  4. Explain differences between actual, declared, and palletized shipment weights.
  5. Subtract any units later received or already reimbursed.

Request Review Through the Correct Channel

Use the shipment’s reconciliation process or the relevant Seller Support category. Reference the shipment and original case. Ask which evidence remains insufficient and provide a direct response; do not select unrelated support categories just to evade an eligibility decision.

The linked US inbound policy ties claims to investigation eligibility and verified delivery. Check its current claim window and preserve the filing date. A case reopening is not a guarantee that expired claims become eligible.

Use a Factual Case Summary

Suggested structure

Shipment ID; verified delivery date; affected SKU/FNSKU; quantity dispatched; quantity received; later receipts/credits; quantity still disputed; supporting documents; and the exact review requested.

Seller Scale recommends keeping this summary consistent across follow-ups. Remove accusations that the evidence cannot establish. Reimbursement remains subject to Amazon’s investigation and policy.

Sources and Scope

The linked sources support the documented points above. Recommendations and hypothetical calculations are editorial guidance, not Amazon rules or promised results. Check the current requirements for your marketplace and account before acting.
