Amazon’s A-to-Z Guarantee exists to protect buyers when an order does not go as expected — whether because a product was not delivered was not as described or arrived in a condition different from what was listed. For Amazon FBA wholesale sellers A-to-Z claims are a fact of business — even the most diligent seller will occasionally face a claim from a customer who is genuinely dissatisfied or from one who is attempting to obtain a refund for a product they actually received correctly. What matters most is not whether you receive claims — it is how quickly and professionally you handle them and whether you have the systems in place to prevent the same issue from generating multiple claims across multiple orders.

We are Brandhunterz Ltd — a UK registered wholesale sourcing company (Company No: 15342697) — and in this complete guide we explain exactly how Amazon’s A-to-Z Guarantee claim process works how claims affect your account health what happens when a claim is granted or denied how to respond to active claims and what systemic changes wholesale FBA sellers should make to prevent claims from accumulating and pushing their Order Defect Rate above Amazon’s threshold.

What Is an A-to-Z Guarantee Claim

The A-to-Z Guarantee is Amazon’s buyer protection programme that allows customers to escalate a dispute about an order directly to Amazon when they have not been able to resolve it with the seller. Buyers can file an A-to-Z claim when they have not received their order or when the item they received is materially different from what was described on the listing. The claim triggers a review by Amazon’s customer service team who then decide whether to grant a refund to the buyer at the seller’s expense or deny the claim.

Claim Reason	What It Means	Common for FBA Wholesale Sellers
Item not received	Buyer says the order was not delivered to them	Occasional — Amazon delivery issue
Item not as described	Product received does not match the listing — wrong variant wrong size wrong product	Most common — listing or ASIN mismatch
Item arrived damaged	Product packaging or product itself was damaged on arrival	Common — prep or product quality issue
Item materially different	Product is a different brand colour model or version from what was listed	Common — wrong ASIN or supplier error

How A-to-Z Claims Affect Your Account Health

The most important fact about A-to-Z claims for sellers to understand is that every claim counts as an Order Defect in your ODR calculation — regardless of whether Amazon grants or denies the claim. This is one of the most counterintuitive aspects of Amazon’s account health system and one that catches many sellers off guard. Even if you provide evidence that the item was delivered correctly and Amazon rules in your favour — the claim still counts as a defect in your ODR for the 60-day window in which it was filed.

Claim Outcome	Counts as ODR Defect	Refund Issued at Seller Expense
Claim granted — buyer refunded	Yes	Yes — seller bears cost
Claim denied — seller wins	Yes — still counts	No — seller not charged
Claim withdrawn by buyer	No — removed from ODR	No
Claim granted — funded by Amazon	No — removed from ODR	No — Amazon absorbs cost

How to Find and Monitor Active A-to-Z Claims in Seller Central

Active A-to-Z claims require a response within a specific timeframe — typically 48 to 72 hours from when the claim is filed. Missing the response window means Amazon will almost certainly grant the claim by default without reviewing your position. Here is exactly how to find and monitor your claims:

How to Respond to an Active A-to-Z Claim

Your response to an A-to-Z claim should be professional factual and supported by evidence. The response is read by Amazon’s customer service team who will use it alongside the buyer’s statement and the order data to make their decision. Here is how to structure your response based on the type of claim:

Responding to an Item Not Received Claim

For FBA orders Amazon’s tracking data is automatically linked to the claim — Amazon can see whether the order was delivered and when. Your response should confirm that you are an FBA seller and that fulfilment and delivery are Amazon’s responsibility for this order. Provide the tracking number and delivery confirmation if visible in your order details. If the tracking shows delivered and the buyer says they did not receive it Amazon typically investigates the delivery independently — your role is to confirm the FBA fulfilment method and provide all available order information.

Responding to an Item Not as Described Claim

This is the most common and most impactful claim type for wholesale FBA sellers. Your response must directly address the buyer’s specific complaint about how the product differs from the listing. If the product does match the listing your response should include specific evidence — a comparison between the listing description and the product specification confirmation of the EAN match and if possible a photograph of the product that demonstrates compliance with the listing. If the product genuinely does not match the listing acknowledge the issue remove your offer from that ASIN and offer a full refund to the buyer immediately.

✅ Strong Claim Response Elements	❌ Weak Claim Response Elements
Specific reference to the order ID and claim reason stated by buyer	Generic response that does not address the buyer’s specific complaint
Tracking confirmation showing delivery or shipment data	No supporting evidence — response based only on assertion
Confirmation that the product matches the listing with specific comparison	Disputing the buyer’s claim aggressively without evidence
Offer of resolution — refund return or replacement as appropriate	No offer of resolution — response focused only on denying the claim
Professional factual tone — no emotional language	Emotional or aggressive language — complaints about the buyer or Amazon’s process

Responding to a Damaged Item Claim

For a damaged item claim your response should confirm that the item was sent in new condition and provide any evidence of your prep process — photographs of packed boxes if available or a description of your packing standards. For FBA sellers if the damage occurred in Amazon’s warehouse or during Amazon’s delivery process Amazon will typically fund the refund and remove the claim from your ODR. If the damage appears to have originated with your supplier or in your prep process acknowledge this investigate and implement corrective action.

When to Offer a Refund Proactively — Before a Claim Is Filed

For FBA sellers one of the most effective strategies for reducing A-to-Z claim counts is proactively resolving customer issues before they escalate to a claim. A customer who receives a damaged product and contacts Amazon customer service before filing a claim can often be resolved at the returns stage — Amazon issues a replacement or refund and no A-to-Z claim is filed. While FBA sellers do not directly handle customer service messages in the same way merchant-fulfilled sellers do they can monitor their FBA returns and damaged unit reports in Seller Central to identify patterns of customer dissatisfaction before those patterns escalate into clusters of A-to-Z claims.

Appealing a Granted A-to-Z Claim

When Amazon grants a claim and issues a refund at your expense you have the right to appeal the decision. Not all granted claims are eligible for successful appeal — but claims where you have clear evidence that the product was delivered correctly and matches the listing have a reasonable chance of being overturned. Here is how to appeal a granted claim:

The Root Cause Prevention System — Eliminating Claim Sources

Responding well to claims is important — but the most powerful long-term strategy for wholesale FBA sellers is eliminating the conditions that cause claims in the first place. Here are the four systemic changes that prevent the most common claim types:

Claim Type Prevented	Systemic Prevention Action
Item not as described — wrong ASIN	Verify EAN to ASIN match in Amazon’s catalogue before every new listing — check title images description and product details against your physical product
Item arrived damaged — packaging failure	Implement and maintain full prep compliance — bubble wrap fragile products — correct box void fill — inspect all supplier deliveries before prepping
Item materially different — supplier error	Count and inspect every unit received from supplier before prepping — compare physical product against purchase order and ASIN listing before labelling
Repeated claims from same ASIN — product quality issue	Remove the ASIN if it generates two or more claims in a 60-day period — investigate whether the product itself generates consistent dissatisfaction regardless of listing accuracy or prep quality

Conclusion — Respond Fast and Fix the Source

A-to-Z claims are unavoidable in any meaningful volume of FBA selling — what separates sellers who manage them well from those who see their ODR and account health deteriorate is the combination of a fast professional response to every individual claim and a systematic approach to eliminating the root causes that generate clusters of claims from the same product. Respond to every claim within 48 hours — provide evidence rather than assertions — and for any ASIN generating multiple claims remove it investigate the cause and fix the issue before relisting. The claim itself always counts as a defect but a handled claim with no further claims from the same source is the best outcome you can achieve once one has been filed.
