The phrase “inauthentic” is broad. Amazon may be worried about a supplier chain, about whether the invoices match the ASIN, about packaging inconsistency, or about repeated complaints that now affect the account.
Read the notice for scope first
- Is the notice limited to one ASIN or category, or does it mention account health more broadly?
- Does Amazon ask for invoices, authorization, or a plan of action?
- Are the document dates, quantities, or entity names likely to be an issue before you upload anything?
If the seller misreads the scope, the document pack often answers the wrong question. That is why good invoices still fail in practice.
Check whether the documents actually fit the claim
Amazon is not impressed by volume. It wants a believable chain from supplier to product to account. If the invoices are incomplete, unverifiable, or outside the relevant time window, more pages will not help.
Weak evidence can become the story
Once Amazon sees an inconsistent document set, the case may shift from a product complaint to a credibility problem.
A better first step is often to review what the notice implies, remove weak documents, and only then prepare the next submission.
