📋 Overview
Order Defect Rate (ODR) is the metric most likely to put an otherwise healthy account at risk, and it usually climbs before a seller notices, because the events that feed it arrive days or weeks after the order ships. This article explains exactly which events Amazon counts as defects, how the percentage is built, and which lever moves each component. It applies to both FBA and FBM sellers — ODR is one of the few customer-service metrics that follows you across fulfillment methods.
🧮 What Amazon Counts as a Defect
ODR is built from three event types. An order counts as defective if it picks up one or more of them, so a single order that generates both a negative feedback and a claim still counts once.
Negative seller feedback
Seller feedback rated 1 or 2 stars counts as a defect. This is seller feedback, not a product review — reviews on the detail page have no effect on ODR, no matter how harsh. Buyers routinely confuse the two and leave product complaints in the feedback field, which is one of the most common removal grounds.
A-to-z Guarantee claims
A claim filed against an order is the heaviest single defect because it is also the one with a response clock attached. Amazon has stated that claims resolved in your favor are not counted against ODR, and that claims on orders shipped on time with Buy Shipping can be covered by Amazon rather than charged to you. Until a claim is closed, treat it as a defect in waiting.
Credit card chargebacks
When a buyer disputes a charge with their card issuer instead of contacting you or Amazon, that order can count as a defect. This is the component sellers monitor least, because there is no inbox notification pattern the way there is with messages and claims. Service-related chargebacks — item not received, item not as described — are the ones your own process can prevent.
What does not count
- Returns and refunds on their own. Refunding a buyer is not a defect; it is often the action that prevents one.
- Low product star ratings and written product reviews.
- Late shipments and pre-fulfillment cancellations. Those feed Late Shipment Rate and Pre-fulfillment Cancellation Rate, which are separate metrics with their own thresholds.
- Buyer messages, even angry ones, unless they escalate into feedback, a claim, or a chargeback.
That last distinction matters operationally: a buyer complaint is not yet a defect. Everything you do between the complaint and the escalation is what keeps ODR flat.
📐 How the Percentage Is Built
ODR is defective orders divided by total orders in the measurement window, calculated over a rolling 60 days from the order date. Amazon’s published target is below 1%. You can read your current figure, and the underlying orders, on the Account Health page in Seller Central.
Two consequences follow from the way that fraction is built, and they explain most of the confusion sellers have about this metric.
Order volume sets how much a single defect costs you
The denominator is orders, not units or revenue. At 200 orders in the window, a single defect puts you at 0.5%; a second one puts you over the threshold. At 2,000 orders, that same defect is 0.05%. Low-volume sellers, seasonal sellers in their off-season, and anyone who just went out of stock are all sitting on a small denominator, which is when ODR spikes hardest.
The window is anchored to the order date, not the complaint date
A defect is attached to the order it came from, so a claim filed seven weeks after purchase lands on an order that is already most of the way through its 60-day window. Meanwhile, the feedback window runs 90 days from the order date and the A-to-z claim window also runs 90 days, which means defects can keep arriving for orders you stopped thinking about. Your ODR today reflects fulfillment decisions you made two months ago.
💡 Pro Tip: When you are actively repairing ODR, stop grading yourself on the headline percentage. It only falls as defective orders age past the 60-day mark, so it lags your fix by weeks. Track new defects per week instead — that number responds immediately and tells you whether the fix worked.
🔧 The Levers That Move Each Component
Work these in order. The first two reduce the defects you have already earned; the rest reduce the ones you are about to earn.
1. Audit existing feedback for removal eligibility
Open Feedback Manager and read every 1- and 2-star entry against Amazon’s feedback removal criteria. The recurring eligible categories are feedback that is purely a product review, feedback that concerns fulfillment or customer service Amazon handled on an FBA order, feedback containing obscene language, and feedback containing personally identifiable information. Removed feedback stops counting. This is a request against published criteria, not an appeal to a buyer, and it is the fastest legitimate reduction available.
2. Respond to every A-to-z claim inside the response window
Amazon gives you 48 hours to respond to a claim. A non-response is effectively a concession, and a conceded claim is a defect you chose. Pull the tracking, the delivery scan, and any buyer messages into a single factual response. If the buyer is right, refunding before the claim is granted is usually the cheaper outcome.
3. Close the gap between buyer complaint and buyer escalation
Most defects pass through your message inbox first. Amazon expects a response to buyer messages within 24 hours, including weekends and holidays. Resolve the issue in that first reply where you can — a refund or replacement offered on day one prevents a claim on day ten. Keep messages inside Buyer-Seller Messaging and within Amazon’s permitted content rules; never ask a buyer to remove or change feedback in exchange for a refund, which is a policy violation on its own.
4. Fix the delivery signals that generate claims and chargebacks
For FBM orders, the two most common roots of “item not received” are a shipment that was late and a shipment with no usable tracking. Keep Valid Tracking Rate above 95%, Late Shipment Rate below 4%, and Pre-fulfillment Cancellation Rate below 2.5%. These are not ODR components, but they are leading indicators of it: when they drift, claims follow within a few weeks. Using Buy Shipping and shipping on or before the expected ship date also brings the claim-protection path into play.
5. Treat recurring defect causes as a listing problem
Group your last 60 days of defects by cause: wrong item, damaged, didn’t match the description, never arrived, sizing. If one cause dominates, the fix is upstream of customer service. “Didn’t match the description” means the detail page is overpromising or the images are ambiguous. “Damaged” on an FBA line usually means packaging that does not survive the conveyor. Fixing the cause is the only change that holds after the current defects age out.
6. Protect the denominator
Pausing sales while you clean up feels prudent and does the opposite. Shrinking the denominator while the numerator stays fixed pushes the percentage up. If the account is healthy enough to keep selling, keep selling the ASINs that do not generate defects, and suppress only the specific ASIN or fulfillment path that is producing them.
⚠️ Mistakes That Keep ODR High
Chasing product reviews instead of seller feedback
Sellers see a 1-star rating on the detail page, assume it hit their ODR, and spend a week on it. It did not. Check Feedback Manager before you react to anything on the detail page — the two systems are entirely separate, and only one of them affects account health.
Letting a claim run out the clock while negotiating with the buyer
Once a claim is open, the 48-hour response clock runs independently of your conversation with the buyer. Respond to Amazon within the window even if you are mid-discussion, then update if the buyer withdraws.
Ignoring chargebacks because nothing alerts you
Chargebacks arrive quietly and can be contested with the same evidence you would use for a claim — order confirmation, tracking, delivery scan, message history. Build a habit of checking for disputes on the same schedule you check claims, rather than discovering them when ODR has already moved.
❓ FAQs
Does refunding a buyer count against my ODR?
No. A refund by itself is not a defect. It is usually the action that stops a defect from forming, which is why refunding early on a disputed order is often cheaper than defending it.
Does ODR apply to FBA orders?
Yes. ODR follows the seller account, not the fulfillment method. The difference is that negative feedback on an FBA order relating to fulfillment or customer service that Amazon handled can be eligible for removal, so audit those entries first.
How fast can ODR actually come down?
Existing defects drop out as their orders pass 60 days from the order date, so the floor on recovery is set by the calendar, not by how hard you work. What you control is whether new defects replace the old ones and how quickly your order volume rebuilds the denominator.
Can I remove negative feedback by asking the buyer to take it down?
You may contact a buyer through Buyer-Seller Messaging to resolve their underlying problem, and a buyer can choose to remove feedback on their own. You cannot offer a refund, a replacement, a gift card, or any other incentive in exchange for removing or changing feedback — that is review and feedback manipulation, and it carries a heavier enforcement risk than the defect you were trying to erase.
