Overview

Amazon provides sellers with a structured system for monitoring and improving how they prepare and ship inventory to fulfillment centers. Through performance alerts, feedback reports, and notifications, sellers receive visibility into problems with their inbound shipments — and guidance on how to prevent those issues from recurring.

For FBA sellers who regularly send inventory to Amazon's warehouses, understanding this feedback system is essential to avoiding costly fees and shipment delays.

Key Points / What Sellers Need to Know

• Three feedback channels — Amazon communicates shipment problems through performance alerts, performance feedback within the shipping workflow, and performance notifications sent directly to your account.
• Actionable feedback — Each alert is tied to a specific problem group, allowing sellers to identify exactly what went wrong and how to fix it for future shipments.
• Per-unit fees may apply — When Amazon has to resolve shipment issues on your behalf (such as relabeling, repackaging, or reboxing), you may be charged per-unit fees for those corrective services.
• Performance summary available — Sellers can view an aggregated performance summary that tracks their inbound shipment compliance over time.
• Problem group tables — Amazon organizes shipment issues into defined problem groups, each with its own set of requirements and corrective actions.

How the Alert System Works

Amazon's inbound performance system monitors every shipment you send to a fulfillment center and evaluates it against a set of preparation, labeling, and packaging requirements. When your shipment doesn't meet these standards, Amazon generates an alert tied to a specific problem group. These problem groups categorize issues such as missing barcodes, incorrect box contents, oversized items, insufficient packaging, and more. Each problem group has a corresponding reference table in Seller Central that explains the issue, the correct preparation standard, and how to avoid the problem on future shipments. Sellers can access these details through the Shipping Queue and the Inbound Performance dashboard.
