Shortage claims are one of the most frustrating issues Amazon vendors face. You fulfill a purchase order in full, yet Amazon records show fewer units received. The result is a deduction from your invoice and a loss that directly impacts your margins.
The problem often becomes worse when reconciliation is slow or incomplete. If invoices, shipment records, and delivery confirmations are not matched regularly, vendors risk missing deadlines, submitting weak evidence, or even overlooking claims altogether.
The good news is that a closed claim doesn’t always mean the end of the process. In Vendor Central, shortage deductions can be redisputed when you have the right documentation and strategy in place.
In this guide, we’ll teach you how to redispute Amazon shortage claims step by step so you can recover payments.
How to Redispute Amazon Shortage Claims: Step-by-Step
1. Gather proper evidence
The first and most important step in redisputing shortage claims is collecting the right evidence. Without documentation, Amazon will not reverse a deduction. Before you start a redispute, make sure you have:
- Proof of Delivery (POD).
- Bill of Lading (BOL).
- Packing slips and Invoices.
- Carrier tracking data.
Organize these documents by invoice and purchase order. Clear, complete, and legible evidence significantly increases the chances of a successful redispute.
2. Understand Amazon compliance requirements
Amazon has strict rules around redisputes. If you do not meet them, your claim will be rejected before it is even reviewed. Always confirm:
- You are referencing the original dispute ID correctly.
- The ASINs and quantities in the redispute exactly match what was shipped.
- The redispute is submitted within Amazon’s dispute window. Late submissions are not accepted.
- All uploaded documents are in an accepted format and easy to read.
Taking time to understand and follow these requirements ensures that your redispute is considered on its merits rather than dismissed for technical reasons.
3. Use the redispute process in Vendor Central
Once you have prepared your evidence and confirmed compliance, follow these steps in Vendor Central:
- Log in to Vendor Central.
- Select the Payments.
- Click on Create a redispute.
- Enter the dispute IDs you want to redispute and click Next.
- Enter the details and hit continue.
- Add justification and upload your supporting documents.

- Review and Submit.
4. Write a clear justification
Your justification statement matters. Amazon reviewers need a concise and professional explanation supported by evidence. A strong justification should include:
- A short description of the shipment, including PO number, carrier, and delivery date.
- Direct reference to attached documents, such as PODs and BOLs.
- A factual explanation of why the deduction is incorrect, for example, a signed POD confirming full delivery.
Avoid long or emotional explanations. Keep it simple and fact-based so the reviewer can quickly connect your evidence to the claim.
5. Monitor the status of redisputes
Submitting a redispute is not the end of the process. Vendors must actively track their redisputes in Vendor Central to ensure they are being processed.
- Review the status of each redispute regularly.
- Follow up if a case is unresolved for longer than expected.
