Why Was My Authenticity Complaint Rejected Even Though I Have an Invoice from the Past 365 Days?

When most sellers face an authenticity complaint for the first time, they focus on “Do I have an invoice?” But Amazon’s actual review process goes far beyond simply checking whether you have one.

The Bottom Line

1. A 365-day invoice is just the minimum threshold, not a guaranteed pass.
2. Amazon doesn’t only check whether the document “looks like an invoice” — they also verify whether the supplier “can be validated.”
3. Quantity coverage, transaction completion status, and supply chain traceability can all determine the outcome.

So the real question isn’t “Do I have an invoice?” — it’s:

Can the documents I submit allow Amazon to independently verify that this inventory was genuinely purchased from a trustworthy supply chain?

Separating “Invoice Compliance” from “Supplier Verifiability”

• Invoice Compliance: Does this document meet the basic requirements?
• Supplier Verifiability: Can Amazon trust that the source behind this document actually exists and is credible?

What Amazon Actually Looks for in Your Invoice

• Whether the invoice date falls within the past 365 days
• Whether the invoice quantity covers sales volume over the past 365 days
• Whether the document is clear, legible, and complete
• Whether the supplier, buyer, date, product description, and quantities are all visible
• In some cases, whether supplementary payment records or upstream supply chain documentation can be provided

5 Most Common Mistakes New Sellers Make

1. Having a 365-day invoice but not checking whether the quantity covers actual sales volume
2. The invoice looks like a purchase order, but the transaction status isn’t sufficiently complete
3. Supplier information is present, but Amazon can’t easily verify it
4. Treating a Letter of Authorization (LOA) as a universal fix
5. Only arguing “My products are genuine” without clearly laying out the supply chain

Conclusion

This isn’t a single-point question of “Do I have an invoice?” — it’s a multi-faceted challenge of “Can you prove your supply chain is authentic using verifiable purchasing documentation?”
