Amazon A-to-z Claims: What Triggers Them, How to Respond and Appeal, and How to Stop Them Hitting Your ODR

Last verified September 2026. An Amazon A-to-z Guarantee claim is a buyer's request for Amazon to step in and refund an order after a seller has not resolved the issue directly. Two things matter for a seller: responding inside the 7-calendar-day deadline with real evidence, and keeping the number of claims granted against you under the 1% Order Defect Rate threshold. This guide covers what buyers can claim, how to respond and appeal, how to prevent claims before they are filed, and how to run this at volume.

What buyers can claim and when

Claims fall into three types: the item never arrived (Item Not Received), the item arrived damaged, defective or materially different from the listing (Item Not As Described), and an unauthorised purchase. A return or refund the seller agreed to but did not honour is treated under the second type. Each type needs different evidence, covered below.

There is a sequence to it. A buyer has to contact the seller first and give them 48 hours to respond before they can file. For a non-delivery, the buyer also has to wait until three days past the latest estimated delivery date. After that, they have up to 90 days from the expected arrival date to file. That 48-hour wait is the single most important number in this guide, because an order-problem message that goes unanswered for 48 hours is, on its own, enough to make the buyer eligible to claim.

FBA orders are largely handled through Amazon's own returns process, and where an FBA delivery fails, Amazon usually absorbs the claim without counting it as a seller defect. FBA does not protect a seller from claims that the item was misdescribed, which are the seller's responsibility whatever the fulfilment method. A-to-z applies in full to seller-fulfilled orders (FBM, including Seller Fulfilled Prime), where the seller owns delivery and carries the evidence burden.

How a claim hits your account

A claim granted against you, where Amazon finds the seller at fault, counts as a defect toward Order Defect Rate, alongside negative feedback and chargebacks, over a rolling 60-day window. A claim that is denied or withdrawn does not count. Amazon's threshold is ODR under 1%; exceeding it risks listing restrictions or account suspension. On an account doing 100 orders a month, one granted claim can be a 1% ODR on its own, so every claim matters regardless of the order value.

Our guide to Amazon performance metrics covers ODR and the other Account Health numbers; our guide to the Amazon 24-hour response rule covers the messaging deadline that keeps you well inside the 48-hour claim window.

Responding to a claim: the window and what to send

You have 7 calendar days from the date the claim was opened, not from the date you saw the notification. Miss it and Amazon decides in the buyer's favour automatically, with the ODR entry that follows.

1. Read the notification and confirm exactly what is being claimed: non-delivery, item condition, or an unhonoured refund. Open the claim on the A-to-z Guarantee Claims page under Performance in Seller Central. The claim type decides what evidence you need.

2. Note the deadline and treat it as fixed. Set Seller Central performance alerts so a new claim reaches you the moment it opens, and route claim notifications to the top of your support queue.

3. Assemble evidence by claim type. For non-delivery: the tracking number, the carrier, the dispatch date and the delivery scan, signature or photo if there is one. For item condition or description: screenshots of the listing with condition notes and photographs, your own photos of the item, and an explanation of exactly where the claim differs from what was listed. For refund disputes: the return record and refund confirmation. In every case, include the Buyer-Seller Messaging thread showing you tried to resolve the issue before the buyer escalated.

4. Submit the response through the A-to-z Claims section of Seller Central, not by replying to the buyer.

5. Keep it factual and specific. Cite the evidence rather than arguing with the buyer's account of events, and include a concrete proposed resolution (full refund, replacement or partial refund); Amazon looks more favourably on a response with a path forward than on one that only contests the claim.

Amazon's reviewers assess a response against a checklist, not on general fairness. What works against you whatever the claim type: missing the window, a vague reply that describes your business rather than the specific order, hostile or emotional language, and wording that admits fault in a way that can be used to escalate further. Once you submit, a decision usually follows within 1 to 7 days.

Preventing the claim before it is filed

Answer every order-problem message within 48 hours, even with a holding reply. The silence itself is the trigger; a buyer who would have accepted "your replacement is on the way" files a claim because they were given nothing else to do. Nights and weekends are where this bites, because the clock does not pause for either.

Refund or replace a clear-cut damaged or wrong-item case before the buyer escalates. A $15 argument that becomes a granted claim costs the $15 anyway, plus an ODR defect, plus the time spent defending it.

For FBM sellers, three shipping habits do most of the work. Ship with valid tracking on every order; delivery proof is the single most useful piece of evidence you can have and the hardest gap to fill afterwards. Set handling and transit times you can beat every time; a missed estimate is a late-delivery claim you manufactured yourself. Buy labels through Amazon Buy Shipping and ship on time (the carrier's first scan counts): with those two conditions met and buyer messages answered within 48 hours, Amazon covers eligible delivery-related claims rather than your ODR.

Route every A-to-z notification, and any message that reads like a pre-claim escalation, to one queue with a single owner rather than mixing it into general support. A high-stakes notice buried under routine tickets is how deadlines get missed.

Appealing a granted claim

If a claim is granted against you and you have evidence that was not considered, or evidence that surfaced afterwards, you can appeal through Seller Central within 30 calendar days of the decision. A successful appeal removes the defect from your ODR and returns the claim amount to your account.

The appeal has to bring something new: tracking that updated to show delivery after your first response, a carrier confirmation that was not yet available, or a message thread showing the buyer confirmed the issue was resolved before escalating. Restating the original points without new evidence rarely changes the outcome, so weigh the effort against the amount at stake. One quirk: the appeal box does not accept attachments, so send any documents to the buyer through Buyer-Seller Messaging and reference them in the appeal text.

Appeals are a safety net, not a strategy. A claim you never receive is always better than one you win.

Refunds, cancellations and address edits from your own tools

A helpdesk connected to Amazon's Selling Partner API can process a refund, cancel an order, or edit permitted order details directly from the ticket, without a separate Seller Central login. Doing this the moment a clear-cut issue comes in, before a claim is filed, is the most effective prevention step there is: the resolution often lands before the buyer has any reason to escalate.

Running claims at volume

Tag every claim notification and pre-claim message so it routes automatically, and treat the 7-day response deadline as its own SLA, separate from and tighter than your general response target. Keep an evidence template ready per claim type so nothing gets assembled from scratch under time pressure.

Check the monthly claim count against ODR, not just the win-or-loss rate on individual claims. A rising number of claims filed, even ones you go on to win, is worth noticing before it shows up as an account health problem.

Handling A-to-z claims from the support inbox

A claim notification arriving as a ticket with the order, tracking and full message thread already attached means nothing needs to be reassembled from Seller Central, your shipping platform and your email under deadline pressure; a response that took an hour to put together by hand takes minutes. A visible countdown against the actual 7-day deadline, not a generic SLA, keeps a claim from getting lost in a general queue, and a countdown on every ordinary Amazon message keeps order problems from ageing past the 48-hour point where they become claims.

Refunds and cancellations that would prevent escalation altogether happen from the same screen, before a claim ever needs defending. An ODR view showing the claim trend against the 1% threshold surfaces a slipping pattern before Amazon's own dashboard would make it obvious. Our Amazon helpdesk software page has the full setup across marketplaces.

Frequently asked questions

What is an Amazon A-to-z claim?

A request a buyer makes directly to Amazon for a refund after a seller has not resolved a problem, non-delivery, a significantly different item, or an unhonoured return, within the 48-hour waiting period after contacting the seller.

How long do sellers have to respond to an A-to-z claim?

7 calendar days from the date the claim was opened. Missing the window results in Amazon deciding automatically in the buyer's favour and an Order Defect Rate entry.

Does an A-to-z claim affect my seller account?

A claim granted in the buyer's favour counts as a defect toward your Order Defect Rate, which Amazon expects to stay under 1%. A claim that is denied or withdrawn does not.

Can I appeal an A-to-z claim decision?

Yes, within 30 days of the decision, if you have evidence or an argument that was not in your original response. A successful appeal removes the defect from your ODR.

How do I prevent A-to-z claims on FBM orders?

Ship with valid tracking through Amazon Buy Shipping, answer every order-problem message within 48 hours, set delivery estimates you can beat, and refund or replace clear-cut issues before they escalate. A helpdesk connected to Amazon's API can process that refund from the ticket immediately, often cutting off the claim before it is filed.
