An A-to-z claim is the only customer issue that can actually cost you your account. Every approved claim has a direct effect on your Order Defect Rate, which is the metric that Amazon watches most closely. And as an FBM seller, you own that exposure outright. There’s no Amazon fulfilment team absorbing the delivery problems for you.
But most A-to-z claims are preventable, and the triggers are almost entirely things you control: how fast you reply, how good your tracking is, and whether you hit the delivery on time.
This guide shows you the triggers, gives you a way to stop them, and provides you a short, honest guide on how to fight claims that get through.
The TL;DR
An Amazon A-to-z Guarantee claim lets a buyer ask Amazon for a refund when an order doesn’t arrive, arrives late or damaged, or doesn’t match the listing. If the claim is granted, the money is taken out of your account and added to your Order Defect Rate, which must stay below 1%.
For FBM sellers, the biggest preventable triggers are unanswered messages (a buyer can file if you don’t respond within 48 hours), weak tracking, and missed delivery estimates. You can prevent claims by replying in time, buying labels through Amazon Buy Shipping, and refunding real problems early. If you think a claim is granted unfairly, you have 30 days to appeal with evidence.
What is an A-to-z claim and when can buyers file one?
An A-to-z Guarantee claim is Amazon’s buyer protection for orders sold and fulfilled by third-party sellers, which lets a buyer ask Amazon directly for a refund when something goes wrong with delivery or item condition.
A buyer can file when an item never arrives, shows up after the latest estimated delivery date, arrives damaged or not as described, or when a return or refund isn’t handled properly.
There’s a sequence to it, and the timing is everything. Per Amazon’s A-to-z Guarantee terms, a buyer is generally expected to contact you first and give you 48 hours to respond before they can escalate. For a non-delivery, they also have to wait until three days past the latest estimated delivery date. After that, you have up to 90 days from the most likely arrival date to file.
Why FBM sellers should care more than most: when you use Fulfilled by Merchant, you can make promises about delivery. In FBA, Amazon takes care of a lot of that, but if you fill your own orders, a “item not received” claim goes straight to you and your Order Defect Rate. That ODR combines granted A-to-z claims, negative feedback, and chargebacks, and Amazon expects it under 1%. One bad week of ignored messages can put real pressure on that number.
How do unanswered messages turn into claims?
Unanswered messages turn into claims because of one specific rule: if a buyer with an order problem contacts you and doesn’t get a response within 48 hours, they become eligible to file an A-to-z claim. That’s it. The silence itself is the trigger. A buyer who would have happily accepted “your replacement is on the way” instead clicks the claim button, because you gave them nothing else to do.
This is the single most preventable trigger on the list. A claim that hits your ODR, costs you the order value, and takes all afternoon to appeal often began as a simple question you missed. Nights and weekends are where this bites hardest, since the 48-hour clock doesn’t pause for either. (Amazon’s wider 24-hour response rule is the habit that keeps you well ahead of the 48-hour claim window.)
So the first rule of claim prevention isn’t really about claims at all. It’s about never letting an order-problem message sit unanswered. Answer fast, even with a holding reply, and most claims die before they’re born.
Which shipping practices invite claims?
The shipping practices that invite claims are weak or missing tracking, optimistic delivery estimates you can’t hit, and not buying your labels through Amazon’s own system. Each one either causes a problem or strips away the protection you’d otherwise have.
Break it down and the fixes are obvious:
- No valid tracking. If a buyer says “it never arrived” and you can’t show where the parcel is, you lose. Valid tracking from an Amazon-integrated carrier is your single best defence against “item not received” claims, and it kills most of those messages before they’re sent.
- Delivery estimates you miss. Promise two-day handling, ship in four, and you’ve manufactured a late-delivery claim out of thin air. Set handling and transit times you can actually hit every time. Under-promise.
- Skipping Amazon Buy Shipping. This is the big one. When you buy the label through Amazon Buy Shipping, ship on time (the carrier’s first scan counts), and respond to buyer messages within 48 hours, Amazon protects you against eligible delivery-related A-to-z claims. They take the hit, not your ODR. Skipping it means carrying risk you didn’t need to.
There is a clear connection between good shipping hygiene and the 48-hour response habit. They both work to stop problems, but they do so from different points. Tracking tells you “where is it” before you even ask. If something does go wrong, Buy Shipping will cover you.
How do you prevent claims before they’re filed?
You prevent A-to-z claims by resolving the buyer’s problem before they ever reach the claim button, which means answering fast, shipping with valid tracking through Amazon Buy Shipping, and refunding genuine issues early rather than fighting them. Prevention is cheaper than appeals every single time, and it protects the metric that actually matters.
Here are the main triggers and the fix for each:
|
Claim trigger |
Why it happens |
How to prevent it |
|---|---|---|
| Unanswered message | Buyer gets no reply in 48 hours | Answer every order-problem message fast, even a holding reply |
| Item not received | No proof of delivery | Valid tracking on every order via Amazon Buy Shipping |
| Late delivery | Missed the estimated date | Set realistic handling and transit times, then beat them |
| Not as described | Listing oversold the item | Accurate titles, photos, and condition notes |
| Refund not honoured | Return request stalled | Process returns and refunds promptly |
There are two habits that do most of the work. First, treat every message about an order problem as important, since the 48-hour clock is also the clock for when claims can be made. Second, on a low-value dispute, just refund. A $15 argument that becomes a granted claim costs you the $15 anyway, plus an ODR defect, plus your time. Refunding first isn’t surrender …it’s protecting your most valuable asset, which is your account.
The practical challenge is simply seeing everything in time. eDesk puts every Amazon message on one screen with the order and tracking attached, and runs an SLA timer that counts down on each one, so an order problem can’t quietly age past 48 hours while you’re packing boxes. For the routine questions, an AI agent answers the predictable “where is my order” messages instantly, day or night, which is exactly the category that turns into non-receipt claims when ignored. eDesk’s AI Agent handles up to 65% of incoming support across channels.
Most A-to-z claims start as a message nobody answered in time. Book a Free Demo and we’ll show you how eDesk makes sure none of them go unanswered, with a countdown on every Amazon message and AI replying around the clock.
eDesk pricing runs from $39 (Essential) to $89 (Growth) to $119 (Professional) per agent per month, with the AI Agent included on every plan and automated resolutions billed at $0.99 each. There’s a 14-day free trial with no card required, so you can connect Seller Central and see your own message queue before deciding anything.
Customer story (a data point, not a promise): Sauder improved its support efficiency by 66% with eDesk while keeping customer satisfaction high across a heavy ticket load. That’s an established seller with serious volume, so a smaller FBM store wouldn’t see the same numbers overnight. But the mechanism is the same one that prevents claims: handle more messages, faster, without anything slipping through.
Can you appeal an A-to-z claim and win?
Yes, you can appeal an A-to-z claim and win, and you have 30 calendar days from Amazon’s decision to do it. A successful appeal removes the defect from your Order Defect Rate, so it’s worth fighting any claim you believe was decided unfairly, especially if you have evidence Amazon didn’t see the first time.
The appeals primer, kept short:
- Respond inside the window first. When a claim is filed, Amazon notifies you by email and on the A-to-z Guarantee Claims page under the Performance tab. Respond before the deadline with your evidence, because if you don’t respond at all, Amazon almost always decides for the buyer by default.
- Lead with proof. Tracking showing delivery, photos, and your message history are what win appeals. Carrier scans that show on-time shipment and delivery are the strongest evidence for delivery claims.
- Know the quirk. In the appeal text box you can’t attach files, so if you need to send documents, use Buyer-Seller Messages to get them to the buyer and reference that in your appeal notes.
- Remember what counts. A claim granted in the buyer’s favour hits your ODR and is funded from your account. A claim that’s denied or withdrawn does not. So even a withdrawal you negotiate directly with the buyer is a genuine result.
For the full internal playbook on routing and documenting these the moment they land, the guide to the A-to-z claim workflow goes deeper than we can here. And if you’re new to owning all of this, the wider Amazon FBM customer service picture sets the context.
Still, the honest truth runs through the whole appeals process: winning one is good, but never receiving it is better. Appeals are a safety net, not a strategy.
Key takeaways and your action plan
A-to-z claims are mostly a prevention game, and the levers are all in your hands. Here’s where to start today.
- Answer order-problem messages fast. The 48-hour silence is the trigger. Close that gap and most claims vanish.
- Put valid tracking on every order. It’s your defence against “item not received.”
- Buy labels through Amazon Buy Shipping. Ship on time and you earn claim protection on delivery issues.
- Set delivery estimates you can beat. Under-promise on handling and transit times.
- Refund genuine low-value problems early. Cheaper than a granted claim and an ODR hit.
- Appeal unfair claims within 30 days. Lead with tracking, photos, and message history.

FAQs
How do I reduce A-to-z claims as an FBM seller?
You reduce A-to-z claims by removing the triggers you control: respond to every order-problem message within 48 hours, ship every order with valid tracking through Amazon Buy Shipping, set delivery estimates you can actually meet, and refund genuine problems before the buyer escalates. Most claims start as an unanswered message or a delivery a buyer couldn’t track, so fast replies and solid tracking prevent the majority before they’re ever filed.
What triggers an Amazon A-to-z Guarantee claim?
An A-to-z Guarantee claim is triggered when a buyer has an order problem (item not received, arrived late or damaged, not as described, or a return/refund not honoured) and either can’t resolve it with you or doesn’t hear back within 48 hours of contacting you. For non-delivery, the buyer also has to wait until three days past the latest estimated delivery date before filing. The unanswered-message route is the most common and the most preventable.
Can I appeal an Amazon A-to-z claim and win?
Yes. You have 30 calendar days from Amazon’s decision to appeal a granted A-to-z claim, and a successful appeal removes the defect from your Order Defect Rate. Appeals are won on evidence: tracking that shows on-time delivery, photos, and your buyer-seller message history. Note that you can’t attach files in the appeal text box, so send any documents through Buyer-Seller Messages and reference them in your appeal.
How do unanswered messages turn into A-to-z claims?
If a buyer contacts you about an order problem and you don’t respond within 48 hours, they become eligible to file an A-to-z claim. The lack of a reply is itself the trigger, so a simple question you missed overnight can escalate into a claim that hits your Order Defect Rate. Answering quickly, even with a brief holding response, keeps a routine query from ever becoming a claim.
Does an A-to-z claim always hurt my Order Defect Rate?
No. Only claims granted in the buyer’s favour count against your Order Defect Rate and are funded from your account. Claims that are denied or withdrawn don’t affect your ODR, which is why responding with evidence (or resolving directly with the buyer so they withdraw) matters so much. Resolving the issue before a claim is filed avoids any impact at all.
