Inauthentic Complaint on Amazon: Which Invoices Actually Work

The invoices that pass an Amazon authenticity appeal are wholesale invoices from a manufacturer or authorized distributor that Amazon can verify, dated within the last 365 days, in your exact business name, with quantities that cover what you sold. Retail receipts, handwritten invoices, documents older than a year and invoices that cover only part of your sales volume are the usual reasons appeals fail.

That is the checklist. The harder part is what to do when your invoices look right and still get rejected, or when the supplier on them cannot be reached. Both are covered below.

Why does Amazon keep rejecting my invoices?

When a seller on the European forums asked why invoices from long-standing suppliers were suddenly rejected, the Amazon moderator listed the likely reasons: the quantity does not cover the total sales volume in the last 365 days, or there is a problem with document quality, validation, or whether the supplier can be verified.

Those three reasons explain most rejections we see:

1. Quantity. As a hypothetical: if you sold 1,400 units of an ASIN in the last year and your invoices show 600, Amazon has 800 units with no documented source. That reads as a gap, not an oversight.
2. Document quality. Blurry scans, cropped pages, missing headers, or a file that looks edited.
3. Verifiability. Amazon cannot confirm the supplier exists and sold to you. A supplier with no website, no working phone number, or an address that does not match their business is a common cause.

Notice what is not on the list: “the invoice was from a supplier we accepted before.” In that same thread, invoices from suppliers that had passed earlier reviews were rejected later. Past acceptance is not a guarantee.

What does a passing invoice contain?

Amazon Sellers Lawyer’s January 2026 guide lists the elements. Use it as a checklist before you upload anything.

1. Supplier name, physical address, phone number and website.
2. Your business name, matching your Amazon seller account exactly.
3. A purchase date within the last 365 days.
4. Clear product descriptions with UPC codes or item numbers you can match to the ASIN.
5. Quantities.
6. Variations (size, color) listed separately, not lumped together.

And what gets rejected, from the same guide: handwritten entries, invoices older than a year, missing contact information, missing UPC codes, and internal documents that are not real purchase records.

A practical point from that guide: submit two versions of each invoice. One completely clean, exactly as received. One with the relevant products circled or highlighted. Reviewers move fast, and making the match obvious helps. Never alter the clean copy.

Is a receipt the same as an invoice?

No, and this is where many resellers get stuck. In a second forum thread, a seller selling Nike products was told Amazon was “unable to verify the supplier”. Experienced sellers in the replies pointed out that the documents were most likely retail receipts, which often carry language prohibiting resale.

The Amazon Sellers Lawyer guide says the same: retail receipts from stores such as Walmart or Target are generally rejected because Amazon wants wholesale invoices that show a verifiable supply chain.

Here is how the document types compare:

In the Nike thread, Amazon’s guidance was that the seller needed invoices from verifiable suppliers, or supply chain documents and letters of authorization from the supplier’s own supplier. For a brand that restricts marketplace sales, that documentation may simply not exist. The replies concluded reinstatement was not realistic. That is a hard answer, but it is better to hear it before spending a month on appeals.

What if my supplier can't be reached?

Amazon verifies suppliers, and an unreachable supplier is one of the reasons the moderator listed. Neither source we checked sets out a formal process for a supplier that has closed. Here is how we handle it, in order:

• Fix what you control on the supplier side. If the supplier is active but hard to reach, ask them to make sure the phone number and email on the invoice are answered, and that their website lists the business. Tell them Amazon may contact them.
• Go up the chain. If your distributor is gone, ask the brand or manufacturer whether they can confirm the distributor was authorized, or issue a letter of authorization. A forum reply in the first thread suggested a brand LOA even where Amazon had not asked for one, and the Amazon Sellers Lawyer guide lists brand authorization letters as useful support.
• Add newer invoices. If you still buy the product, a fresh invoice from a verifiable source covering current volume is often stronger than arguing about an old one.
• Accept the limit. If you cannot document the chain and you cannot get new stock from a verifiable source, consider removing the offer. Unresolved authenticity issues are a serious account-level risk, and forum replies in the Nike thread said so plainly.

How do I build the appeal?

Here is the outline we use for an authenticity appeal. Keep it short and factual.

1. Summary (two or three sentences). The ASIN, the complaint, and that you are attaching supply chain documentation.

2. Supply chain. Who you buy from, how long, and whether they are the manufacturer or an authorized distributor. One sentence per supplier.

3. Documents attached. List each invoice: supplier, date, units, matching ASIN. Then a line with total invoiced units against total units sold in the last 365 days.

4. What caused the complaint. If a buyer received a damaged, mislabeled or returned unit, say so and say how it happened. If you do not know, say what you checked.

5. What you changed. Concrete steps with dates: inbound inspection, return handling, supplier vetting, stopping purchases from a source.

Do not attack the buyer or Amazon, and do not send the same documents again after a rejection without changing anything. If you are on a second or third rejection, our post on what to do when Amazon rejects your plan of action again covers the escalation side.

What we'd do this week

• Pull 12 months of sales by ASIN from your reports and set them next to invoiced units. Close the gap before you appeal, not after.
• Call every supplier on the invoices and confirm their phone, email and website work. Ask whether they will confirm the sale if Amazon contacts them.
• Prepare clean and highlighted copies of each invoice as PDFs, full pages, readable.
• Check whether the brand allows marketplace resale. If not, decide now whether this product is worth the account risk.
• Review the rest of the catalog for products sourced the same way. The complaint on one ASIN usually signals exposure on others.

Brands with resellers on their listings face the reverse problem, and we cover that in someone is already selling your brand on Amazon. If you are a seller with repeat authenticity flags, our account suspension and reinstatement team can review the documents before you submit. Rules change, so as of October 2026, confirm the exact documentation request in your notice in Seller Central before you send anything.
