An “inauthentic” complaint is one of the more alarming messages a seller can get — Amazon is effectively questioning whether your product is genuine, and it can deactivate the listing (or the account) fast. But these are appealable. The key is understanding what Amazon actually wants: proof of a legitimate supply chain.
What does “inauthentic” mean?
It doesn’t always mean counterfeit. Amazon uses “inauthentic” when a buyer or rights owner raises doubt about a product’s authenticity, or when it wants you to prove where your stock came from. Either way, the resolution is the same: show a valid, verifiable sourcing trail.
What Amazon wants in your appeal
The centrepiece is usually invoices — and they must meet Amazon’s criteria:
- Genuine invoices (not receipts) from a legitimate supplier or authorised distributor.
- Dated within Amazon’s required recent window and showing your business name and address.
- Quantities that reasonably match what you’ve sold.
- Supplier details Amazon can verify (name, address, phone, website).
- A letter of authorisation from the brand if you’re reselling a brand that requires it.
How to write the appeal
- Address the specific complaint — don’t send a generic apology.
- State your root cause honestly, and the corrective + preventive actions (this mirrors a Plan of Action).
- Attach compliant invoices and any authorisation letters.
- Keep it concise, factual and professional.
Mistakes that get appeals rejected
- Submitting receipts (retail purchases) instead of supplier invoices — a red flag to Amazon.
- Editing or altering invoices in any way — this can permanently harm your case.
- Invoices from sources Amazon can’t verify, or quantities that don’t match sales.
- Arguing instead of demonstrating a clean supply chain.
Prevent it happening
Source only from legitimate suppliers or authorised distributors, and keep every invoice from day one. If you ever get an inauthentic complaint, having compliant paperwork ready turns a crisis into a quick fix.

Frequently Asked Questions
What does an “inauthentic” complaint on Amazon mean?
It means a buyer or rights owner has questioned whether your product is genuine, or Amazon wants you to prove where your stock came from. It doesn’t always mean counterfeit — but you must demonstrate a legitimate supply chain to resolve it.
What invoices does Amazon accept for an inauthentic appeal?
Genuine invoices (not retail receipts) from a legitimate supplier or authorised distributor, dated within Amazon’s recent window, showing your business details, with verifiable supplier information and quantities that reasonably match your sales.
Can I use a retail receipt as proof of sourcing?
No. Retail receipts are a common reason appeals fail. Amazon expects supplier or distributor invoices that prove a genuine wholesale supply chain.
Should I edit my invoice to match Amazon’s format?
Never alter an invoice. Editing documents can permanently damage your case and your account standing. Submit genuine, unmodified invoices only.
