Hello @DELWIS_HUB,

Virgil here to assist.

Based on my observations from your post, I want to provide you with a sense of direction moving forward.

The late shipment rate (LSR) represents orders that have been confirmed after the expected ship date as a percentage of total orders over both a 10-day or a 30-day period. LSR only applies to seller-fulfilled orders.

It is important to confirm the shipment of orders by the expected ship date so that Customers can see the status of their shipped orders online. Orders that are confirmed late can negatively affect the Customer experience and lead to increased Claims, negative feedback and Customer contacts.

For orders shipped through Amazon Easy Ship, ship confirmation happens automatically when Amazon picks up the orders.

Sellers are recommended to keep the Late Shipment Rate under 2% to enable a good Customer experience and maintain good Seller performance metrics. To avoid impacting these metrics, we recommend that you ship out your orders by the expected ship date.

Consistent poor performance can result in a poor Customer experience and could lead to enforcement action including loss of selling privileges on Amazon.

For more details, please visit Late Shipment Rate.

Furthermore, we would recommend you to modify your handling time to accommodate for off days and national holidays.

For detailed information, kindly check Change Handling time.

Thank you for your post. I hope my response is beneficial towards your business.

Best Regards
Virgil.
