An A-to-z Guarantee claim is a buyer asking Amazon to step in and refund an order sold by a third-party seller. One number decides what it costs you: an A-to-z Guarantee claim that isn’t denied counts as a defect in your Order Defect Rate (ODR), and your ODR target is under 1% of orders over a 60-day period (Amazon, sell.amazon.com, checked 2026-07-27). That is why “just refund it” is sometimes cheap and sometimes expensive: a refund issued before a claim is filed costs you the order, while a claim granted against you costs the order and a defect.
This guide is a triage framework: identify which of the three claim types you have, check the buyer against Amazon’s published eligibility conditions, send the evidence that type requires, then close the process gap. Every rule below is sourced to an Amazon-published page with its check date — and where Amazon publishes no such rule outside a logged-in Seller Central account, this guide says so instead of guessing.
The Number Behind Every Decision: Order Defect Rate
Amazon defines an order defect as one that results in “negative customer feedback (reviews of less than three stars), an A-to-z Guarantee claim that isn’t denied, or a chargeback claim” (sell.amazon.com, checked 2026-07-27). The pivot in that wording is the word denied: the defect attaches to the claim outcome, so contesting a winnable claim is worth real money. Amazon’s public definition says nothing about who funds the refund, so do not assume an Amazon-funded grant is metric-free — check the claim’s status on your own Account Health page.
Amazon’s guidance is to “keep your ODR under 1% to avoid restrictions on your selling privileges” (sell.amazon.com, checked 2026-07-27). Its worked example sits on a different page: on 300 orders in 60 days, aim for “fewer than three” combined low ratings, A-to-z claims and chargebacks (sell.amazon.com, checked 2026-07-27).
| Orders in trailing 60 days | Defects before you cross 1% |
|---|---|
| 100 | 0 (one defect = 1.0%) |
| 300 | 2 |
| 1,000 | 9 |
| 5,000 | 49 |
That table is arithmetic on Amazon’s stated 1% target, not a separate policy. Low-volume and seasonal accounts have almost no margin, so one granted claim there is a metric event rather than an accounting event. If your account is already restricted, the recovery path is a different document — see the Amazon suspension appeal Plan of Action template.
Gate 1: Which of the Three A-to-z Guarantee Claim Types Is This?
“A-to-z claim” is one name for three processes with different evidence and different money at stake. Sort the notice before writing a word.
| Type | What the buyer claims | What decides it |
|---|---|---|
| A. Not received | The package never arrived | Delivery evidence: tracking, carrier scans, ship-on-time record |
| B. Not as described, damaged, or a return gone wrong | The item is wrong or broken, or the return was mishandled | Listing accuracy, return authorization record, refund timing |
| C. Property damage or personal injury | A defective product caused injury or damage | A separate Amazon claims process involving insurers, capped at $1M |
Type C is not a refund dispute and does not behave like one — it is handled below on its own terms.
Gate 2: Was the Buyer Eligible to File?
Amazon publishes the buyer-side conditions openly, which makes them your first diagnostic: a condition that was not met is a factual point for your response. Per the A-to-z Guarantee page (checked 2026-07-27), the order must be from a third-party seller, “the last possible delivery date of your order is 90 days or less,” and at least one of these must apply:
- Not received — “Three days have passed since the latest estimated delivery date OR the tracking shows a delivery confirmation (whichever is sooner) AND you have contacted the Seller more than 48 hours ago but they did not respond or resolve the issue.”
- Damaged, defective, or not as described — “you have requested a return more than 48 hours ago and the seller hasn’t authorized your return request.”
- Return mishandled — an international seller gave no US return address, prepaid label or refund-without-return; the return request was closed or unauthorized; or the label had an invalid tracking ID.
- Refund not received — “Seven days have passed since the return was delivered to the seller.”
- Extra charges (for example customs) the seller did not cover.
Note what conditions 1 and 2 share: your 48-hour silence is the trigger, so most claims of those types come from a missed message rather than the underlying problem. Amazon also tells buyers a decision “can take us up to one week” (Request an A-to-z Guarantee Refund, checked 2026-07-27) — the clock runs whether or not you have opened the notice. Outside the guarantee entirely: “digital items, services, stored value instruments, Spot Buys or automobiles,” and any buyer who already requested a refund or chargeback from their payment provider.
Type A — Not Received: Evidence and Response
Evidence checklist
- Tracking number with the carrier’s first-scan timestamp (proves ship-on-time)
- Full scan history including delivery confirmation and any address or GPS detail
- Whether the label was bought through Amazon Buy Shipping (see prevention below)
- Buyer-Seller Messaging thread showing a reply inside 48 hours
Response template
Order [ID], shipped [date] via [carrier], tracking [number]. [If bought through Buy Shipping:] The label was purchased through Amazon Buy Shipping and the carrier’s first scan was recorded [date/time], within the ship-by date of [date]. Tracking shows delivery on [date] to the address on the order. [If you replied inside the window:] We replied in Buyer-Seller Messaging on [date/time], within 48 hours of the buyer’s first message. We have offered [replacement / refund]. Full scan history is attached.
Keep it to verifiable facts with timestamps — reviewers match your statement against records Amazon already holds, so anything that cannot be checked against a scan or a message timestamp adds nothing.
Type B — Not as Described, Damaged, or a Return Gone Wrong
This family turns on listing accuracy and return handling, and Amazon’s published refund table is asymmetric: for an item “damaged, defective, or materially different from what you ordered” the buyer is owed product cost, original shipping and return shipping; for “any other reason” it is product cost only, and “restocking fees may be deducted” (A-to-z Guarantee, checked 2026-07-27). “The item is fine, this is buyer’s remorse” is therefore not rhetoric — it changes what the buyer is owed.
Evidence checklist
- Pre-ship photos of the exact unit or batch, dated
- The listing text and images as they stood on the order date
- Return request record: when it arrived, when you authorized it, what address or label you gave
- Proof the label tracking was valid and the address was in the US for US buyers
- Refund timing record and inspection photos if the return came back
Response template
Order [ID]. The return request was received [date/time] and authorized [date/time], with [prepaid label / US return address] and tracking [number]. The listing at the time of order stated [exact specification]; the unit shipped matches it, per the dated pre-ship photos attached. [If returned:] The return reached us [date] and a refund of [amount] was issued [date].
If the listing genuinely was inaccurate, refund immediately and fix the wording — the same copy produces the same claim next month. Listing-side prevention is covered in Amazon listing optimization.
Type C — Property Damage or Personal Injury
Different process, different clock. Per Amazon’s Property Damage and Personal Injury page and the A-to-z Claims Process Terms and Conditions (Amazon’s stated last update August 10, 2021; both checked 2026-07-27):
- The buyer must file “within 90 days after the incident occurs,” and claims “are usually resolved within 90 days.”
- It covers products “sold by Amazon or third-party sellers,” capped at the purchase price plus “up to $1 million for medical expenses, lost wages, and property damage.”
- Buyers must supply “evidence of your loss, like insurance records, photographs, repair bills, wage records, or medical bills.”
- Amazon “may involve the seller in our determination” and may share claim information with the seller, their insurer and Amazon’s own insurer.
Your side is documentary and fast: lot and supplier records, compliance certificates and test reports, your liability policy and broker contact, prior incident reports for the ASIN. Do not settle directly with the buyer without involving your insurer — most policies require notice, and Amazon’s terms make a buyer who “already received compensation from another source such as the seller or manufacturer” ineligible through this process.
The Deadline Map: What Amazon Publishes, and What It Doesn’t
Published openly by Amazon (all checked 2026-07-27):
| Rule | Value | Source |
|---|---|---|
| Buyer’s order-age limit | Last possible delivery date 90 days or less | A-to-z Guarantee |
| Seller silence that unlocks a claim | 48 hours after buyer contact or return request | Same page |
| Amazon’s review time | “Up to one week” | Request an A-to-z Refund |
| Buyer’s appeal window after denial | “Within 30 calendar days of the decision” | Appeal a Denied A-to-z Refund |
| Property damage / injury filing window | 90 days after the incident | Property Damage and Personal Injury |
| ODR target | Under 1% over 60 days | sell.amazon.com |
Not published on any public Amazon page: the marketplace seller’s deadline to respond to a filed claim, and the seller’s appeal window after an adverse decision. Those pages sit behind a Seller Central login, so this guide assigns them no number. Two Amazon sources are widely quoted as if they filled that gap, and both need labelling:
- Amazon Pay’s A-to-z Guarantee Policy for Sellers gives “5 business days to respond to Amazon’s notification” and “up to 30 calendar days to appeal that decision” (pay.amazon.com, checked 2026-07-27) — but it governs purchases on third-party sites using Amazon Payments, not marketplace orders.
- An Amazon Seller Forums post by an Amazon community manager (“Xander_Amazon,” moderator-updated roughly a year before this check) lists a 48-hour message window, a 5-day return-label window and 2-business-day refund processing, while telling sellers to “always check the help pages for the most up-to-date requirements” (Seller Forums, checked 2026-07-27) — Amazon-authored, but a forum post, not a policy page.
Either way: treat a claim notice as same-day work, and follow the deadline stated in the notice itself.
Should You Refund, or Contest?
- Is the buyer’s ground provably wrong? Tracking shows delivery in the window, the return was authorized inside 48 hours, the listing matches the item. Contest — a denied claim is not a defect.
- Is it Type C? Not a refund decision. Notify your insurer and respond through the claims process.
- Did you miss a window or ship the wrong item? Refund now, before it is granted. Once granted you pay the money and carry the defect.
- Ambiguous and low value? On a small account the ODR arithmetic above makes refunding cheaper than a coin flip; a high-volume account with a healthy ODR can afford a documented contest.
- Already made whole elsewhere? Amazon tells buyers: “If you request a refund or chargeback from your payment provider, you’re not eligible for a refund through A-to-z Guarantee.”
One underused fact: buyers can withdraw a claim, including after it is granted — Amazon’s help page states a customer may “cancel your request before we make a decision or reverse the refund if your A-to-z Guarantee Refund has been granted” (Cancel or Reverse an A-to-z Guarantee Refund, checked 2026-07-27). When you fixed the problem after filing, pointing the buyer to that path is the only route that does not depend on Amazon reversing its own decision; the seller-side appeal against an adverse decision is the other, and its window is one of the numbers Amazon publishes only behind a Seller Central login.
Prevention Checklist
Amazon publishes exactly one protection mechanism for delivery claims, with three conditions that must all hold: to be eligible for A-to-z claim protection you must “purchase the shipping label through Amazon Buy Shipping, ship on time (considered the moment of the carrier’s first scan), and respond to any customer inquiry in Buyer-Seller Messaging within 48 hours” (sell.amazon.com/tools/buy-shipping, checked 2026-07-27). Amazon states sellers meeting those conditions get “12x more Amazon-paid refunds for A-to-z claims” than on-time orders shipped without Buy Shipping — Amazon’s own comparison.
Fulfillment
- Buy Shipping labels on seller-fulfilled orders where the protection matters
- Ship-by dates tracked against the carrier’s first scan, not against when you packed
- Buyer-Seller Messaging answered inside 48 hours, even when the answer is “we are looking into it”
- Returns authorized promptly, with a valid US return address or a working prepaid label
- Refunds issued promptly once a return is delivered back to you
Listing and description
- Dimensions, quantity, colour and compatibility match the physical unit
- Images show what actually ships, including what is not included
- Variations do not mix materially different items under one parent
- Known limitations stated in the bullets, not left to be discovered
Under FBA, Amazon handles customer service and returns for those orders, changing both your exposure and your controls — the split is laid out in FBA vs FBM.
The Adjacent Money: What A-to-z Claims Are Not
A-to-z claims are money flowing out. A separate mechanism covers money owed to you: FBA reimbursements for inventory Amazon lost or damaged, and SAFE-T claims for seller-fulfilled orders Amazon refunded on your behalf. Different processes, different filing paths — resolving an A-to-z claim does nothing for them. Options and commission structures are compared in best Amazon FBA reimbursement services; to size the gap without paying commission, a flat-fee audit tool such as ReimburseOps runs on Seller Central CSV exports — $19/month with a free tier, four detection rules, flagging discrepancies rather than filing cases for you (data checked 2026-07-27).
Frequently Asked Questions
Does an A-to-z claim always hurt my Order Defect Rate?
No — only a claim that is not denied. Amazon defines a defect as an order resulting in “negative customer feedback (reviews of less than three stars), an A-to-z Guarantee claim that isn’t denied, or a chargeback claim” (sell.amazon.com, checked 2026-07-27). A claim you contest successfully does not count.
How long does a buyer have to file an A-to-z claim?
Amazon’s public eligibility page (checked 2026-07-27) requires “the last possible delivery date of your order is 90 days or less,” plus a qualifying condition — three days past the latest estimated delivery date, or a return request left unauthorized for more than 48 hours. Property damage and injury claims run on their own 90-days-after-the-incident clock.
How long do I have to respond to a filed claim?
Amazon does not publish the marketplace seller response window anywhere reachable without a Seller Central login, so this guide states no number — the deadline for your claim appears in the notice itself. The widely quoted “5 business days” comes from Amazon Pay’s policy for purchases on third-party sites, a different program.
Will refunding stop the buyer leaving negative feedback?
No — separate systems, and a one- or two-star rating is its own ODR defect. Refunding closes the claim path, not the feedback path.
Conclusion
An A-to-z claim is not one problem. Sort it into not-received, not-as-described, or property damage first — each is decided on different evidence, and only one is really a refund decision. Then check the buyer against Amazon’s published conditions: two of the three main triggers are your own 48-hour silence, which makes most claims process failures rather than product failures. Contest what is provably wrong, refund fast what is genuinely your miss, route injury claims to your insurer.
