- Start with the exact authenticity notification and affected ASINs; do not assume every complaint asks for the same documents.
- Amazon may request supplier invoices, supplier contact information, authorization or a Plan of Action depending on the case.
- Invoices should be genuine, complete, readable and capable of linking the supplier transaction to the affected product and quantities.
- Do not edit or fabricate sourcing documents. If evidence is weak, identify the real gap and improve future sourcing controls rather than manufacturing proof.
1. What a product-authenticity complaint means
A product-authenticity complaint means Amazon has a concern about whether goods offered or sold as a particular product are genuine. The concern may follow a customer complaint, an internal review, a rights-owner issue or another verification process.
The enforcement can be limited to one ASIN or can affect broader selling privileges depending on the notice and account history. The exact Performance Notification should determine the response.
2. Capture the exact scope before gathering documents
Record every affected ASIN, the notification date, the allegation, the period Amazon asks you to cover and each requested item. Some notices ask mainly for invoices; others also request supplier details, authorization, a Plan of Action or additional information.
If several ASINs are named, map each ASIN to its supplier and purchase records. Do not send one unrelated invoice and assume it covers the entire complaint.
3. What Amazon says invoices should demonstrate
Amazon’s guidance for authenticity complaints says it may ask sellers to provide supplier invoices or supplier contact information. Amazon forum guidance on invoice requirements says documents should be itemized, authentic and unaltered and should contain enough transaction and product information for verification.
In practice, the document should help establish who sold the goods to the seller, when the transaction occurred, what products were purchased and in what quantities. The product description or identifier should be specific enough to connect the invoice to the affected goods.
4. Invoice-readiness checklist
Before submission, check the seller/buyer legal name and address, supplier legal name, supplier contact information, invoice number and date, product descriptions or identifiers, quantities and any tax/business information that appears on the genuine document. Make sure every page is visible and readable.
Amazon’s invoice guidance commonly refers to invoices issued within the requested period and quantities sufficient to support the seller’s sales volume for the cited ASINs. The actual notification should control the exact date range and quantity requirement for the case.
5. Do not alter a genuine invoice to make it look stronger
Amazon states that documents must be authentic and unaltered, although some instructions may allow pricing information to be removed. Do not add product names, quantities, supplier websites, signatures or other details to an existing invoice after the fact.
If a genuine invoice is too vague to identify the product, use legitimate supporting records where allowed—such as purchase orders, payment proof, delivery records, supplier correspondence or manufacturer authorization—rather than editing the source invoice.
6. Supplier verification can be as important as the invoice
Amazon may verify the supplier. Keep current supplier contact information and records that show the business is genuine and the transaction occurred. If the supplier refuses to confirm a legitimate transaction or cannot be independently identified, the seller should recognise that this can weaken the evidence.
A professional-looking invoice is not enough if the underlying supplier or transaction cannot be substantiated. Build supplier due diligence into sourcing before products are listed.
7. Brand owner, manufacturer and private-label sellers
A manufacturer or private-label seller may not have a reseller-style invoice for finished goods because it produces the product itself. In that situation, the notice may require a different evidence set: manufacturing records, raw-material or packaging purchases, trademark/brand ownership, authorization, product photographs, regulatory documents or other proof relevant to the business model.
Do not invent a reseller supply chain if the actual business is manufacturing or private label. Explain the genuine route by which the product is produced and controlled.
8. If the complaint is wrong: build an evidence-based dispute
If the products are genuine and sourcing is traceable, organise the evidence so Amazon can verify it quickly. Use a concise cover explanation that maps each affected ASIN to the supplier, invoices and quantities. Point out any factual mismatch in the complaint without attacking the customer or reviewer.
Avoid unnecessary admissions. A seller should not say it sold counterfeit goods merely because Amazon used an authenticity complaint workflow when the genuine evidence shows otherwise.
9. If the sourcing process was weak: correct the real failure
If the seller purchased branded goods from a source that cannot be verified, mixed stock from multiple sources without traceability or failed to retain adequate invoices, the response should address that real control failure. Containment may include stopping purchases, quarantining affected inventory and removing unsupported offers where appropriate.
Preventive controls can include approved-supplier onboarding, invoice retention, quantity reconciliation, authorization checks, receiving inspections and periodic supplier verification.
10. Common reasons an authenticity submission becomes weak
Common problems include cropped or unreadable invoices, documents from the wrong time period, quantities that do not cover the relevant sales, generic descriptions that cannot be connected to the ASIN, inconsistent seller names/addresses, supplier details that cannot be verified and large bundles of unrelated invoices.
Another common mistake is deleting the ASIN and assuming the complaint has disappeared. If Amazon has requested evidence or account-level information, the notification still needs to be addressed through the indicated workflow.
Invoice and sourcing evidence checklist
- Match every affected ASIN to the correct supplier and genuine purchase document.
- Confirm invoice date and quantities satisfy the period/volume Amazon requested in the actual notice.
- Verify supplier legal name, contact details and transaction information are visible and genuine.
- Check the product description or identifier can reasonably be connected to the affected goods.
- Keep the complete document readable; do not add, rewrite or fabricate invoice information.
- Retain supporting purchase, payment, delivery and authorization records where relevant.
- If the business manufactures/private-labels the product, use evidence that reflects that real supply chain.
Frequently asked questions
Does every authenticity complaint require an invoice?
No. Amazon may request invoices, supplier contact information, authorization, a Plan of Action or another form of evidence. Follow the exact notification.
Can I edit an invoice so the ASIN or product name is clearer?
Do not alter the document. Amazon states that sourcing documents should be authentic and unaltered. Use legitimate supporting records if the original description is insufficient.
What if the invoice is genuine but the supplier has no website?
Do not invent a website. Provide the genuine supplier information available and any other evidence permitted by the notice. Supplier verifiability is important, but the response must remain factual.
What if I manufacture the product myself?
Use the evidence that fits the real business model. Manufacturer/private-label cases may rely on production, brand ownership, packaging, regulatory and supply-chain records rather than a reseller invoice for finished goods.
Is deleting the listing enough?
Not usually when Amazon has requested sourcing evidence or account-level information. Deletion may be a containment step, but it does not by itself answer the complaint.
