Overview

Amazon's On-Time Delivery Rate (OTDR) defect report is a Seller Central tool that identifies orders delivered after their promised delivery date without an approved promise extension. This metric is a key component of Amazon's account health framework, and sellers who consistently miss delivery windows risk account-level consequences. Understanding how to read and act on this report is essential for maintaining good standing and protecting Buy Box eligibility.

Key Points / What Sellers Need to Know

• What the report tracks — The OTDR defect report flags individual orders where the actual delivery date exceeded the estimated delivery date shown to the customer at checkout, excluding cases where Amazon granted a promise extension.
• Where to find it — Sellers can access their on-time delivery rate and the associated defect report through the Account Health dashboard in Seller Central, under the Shipping Performance section.
• Promise extensions matter — Orders that received a promise extension from Amazon (due to weather, carrier delays, or other qualifying events) are excluded from defect calculations, so the report focuses only on delays within the seller's control.
• Metric threshold — Amazon expects sellers to maintain an on-time delivery rate of 97% or higher. Falling below this target can trigger warnings and, if sustained, may lead to shipping privilege restrictions.
• Seller-fulfilled orders only — This metric applies exclusively to orders fulfilled by the seller (MFN/FBM). Orders fulfilled through FBA are managed by Amazon's logistics network and are not counted against the seller's OTDR.

How the Defect Report Works

The OTDR defect report provides a detailed, order-level breakdown of shipments that missed their delivery promise. Each entry in the report typically includes the order ID, the promised delivery date, the actual delivery date, and the shipping carrier used. Sellers can filter and sort the report to identify patterns — for example, whether late deliveries cluster around specific carriers, regions, or product types. By reviewing the report regularly, sellers can pinpoint operational bottlenecks before they become systemic problems. The report is updated on a rolling basis, typically reflecting performance over the past 30 days, though Amazon may evaluate longer windows for account health decisions.
