Amazon continuously refines its seller performance metrics to improve customer experience and marketplace reliability.One of the latest operational changes involves the Amazon On-Time Delivery Rate (OTDR) update, which directly affects sellers using seller-fulfilled shipping models.Previously, poor delivery performance could result in broad penalties affecting multiple listings across a seller’s catalog. With this update, Amazon now focuses on listing-level enforcement, meaning that only the products contributing to late deliveries may be deactivated.While this change introduces more targeted enforcement, it also increases the importance of closely monitoring shipping performance metrics.For Amazon sellers, especially those using Fulfilled by Merchant (FBM) or Seller Fulfilled Prime, shipping reliability is now a critical operational metric that directly affects listing visibility and revenue.We explore how the Amazon OTDR update affects sellers, why shipping performance is becoming a strategic advantage, and how businesses can optimize their fulfillment processes to remain competitive.
The Amazon On-Time Delivery Rate (OTDR) measures the percentage of seller-fulfilled shipments delivered on or before the estimated delivery date promised to customers.The metric applies specifically to tracked seller-fulfilled shipments, making accurate tracking and carrier performance essential.OTDR is calculated using the following formula:Packages delivered by estimated date ÷ total tracked shipmentsKey requirements include:
Maintaining strong OTDR performance helps ensure that delivery promises match actual customer experiences.
Amazon’s marketplace relies heavily on customer trust and delivery reliability.Shipping delays can lead to:

However, sellers must still maintain an OTDR above 90% to avoid enforcement actions.
The OTDR update introduces several operational considerations for sellers managing fulfillment processes.
Shipping reliability is becoming increasingly tied to product performance.Listings with repeated delivery delays may lose visibility if Amazon deactivates them due to poor OTDR.
Sellers must regularly review carrier performance to ensure delivery timelines remain accurate.Reliable carriers and accurate transit times help maintain strong OTDR performance.
Incorrect handling time settings can lead to unrealistic delivery estimates, increasing the risk of late shipments.Sellers should adjust handling times based on actual fulfillment capacity.
