A2Z (A-to-Z Guarantee)

Amazon & D2C glossary · Harpy Media

The A-to-Z Guarantee (A2Z) is Amazon’s buyer-protection program covering orders from third-party sellers. If an item shows up late, arrives broken, never arrives, or doesn’t match what the listing promised, the buyer can file a claim — and if it’s granted, Amazon refunds them directly from your balance.

What is A2Z?

The A-to-Z Guarantee (A2Z) is Amazon’s buyer-protection program covering orders from third-party sellers. If an item shows up late, arrives broken, never arrives, or doesn’t match what the listing promised, the buyer can file a claim — and if it’s granted, Amazon refunds them directly from your balance.

For FBM sellers especially, A2Z claims are the sharp end of buyer protection. The refund is the smaller hit: a granted claim also counts as an order defect, landing on your Order Defect Rate. Cross Amazon’s ODR threshold and you lose Buy Box eligibility first and your account second. Two failures, one click.

How the claim process actually runs

The buyer must contact you first and wait 48 hours before filing. After that they typically have up to 90 days from the latest estimated delivery date. Claims are ruled on evidence: tracking scans, delivery confirmation, listing accuracy. Win the evidence war and the claim is denied; lose it and the refund debits your account, with roughly 30 days to appeal if you can prove delivery or listing accuracy.

How A2Z connects to your Order Defect Rate

ODR aggregates three defect types — negative feedback, A-to-Z claims granted, and credit card chargebacks — as a percentage of orders, and Amazon watches it against a 1% ceiling. What makes A2Z claims uniquely dangerous is that they’re often triggered by things you can fix quietly: vague listings, slow dispatch, weak packaging. Every claim granted is a customer telling you exactly where the operation leaked.

FBA sellers get an easier ride — for a reason

For FBA orders, Amazon fulfilled the promise itself, so logistics-driven claims are Amazon’s problem, not your ODR. That’s not charity — you paid for it in fulfilment fees. FBM sellers carry the full risk and therefore owe themselves tighter controls: same-day dispatch, tracked shipping on everything, packaging rated for the journey, and listings that promise only what’s in the box.

In practice

An FBM seller ships a ceramic pour-over set with tracked courier but packs it in a single layer of bubble wrap. It arrives shattered; the buyer files A2Z after the 48-hour contact window. Claim granted: refund debited, defect recorded. The fix was a $0.40 box insert — the cheapest insurance the seller never bought.

How Harpy Media helps

We audit FBM operations for exactly this failure pattern — listing accuracy, packaging economics, dispatch metrics — because defect-rate math is unforgiving and reversible only before the threshold, not after.

A2Z FAQ

What is an Amazon A-to-Z Guarantee claim?

A formal buyer dispute over a third-party order — non-delivery, damage, or an item materially different from the listing.

How does an A2Z claim affect my account?

A granted claim debits the refund from your balance and adds a defect to your Order Defect Rate. Above 1% ODR, Buy Box eligibility and then the account itself are at risk.

How long does a buyer have to file a claim?

They contact you first and wait 48 hours; after that, typically up to 90 days from the latest estimated delivery date.

How do I appeal a granted A2Z claim?

Within about 30 days, through Seller Central, with objective evidence — tracking scans proving delivery, carrier correspondence, or the listing as it appeared at purchase time.
