避免延迟发货
在预计配送时间之前确认订单发货十分重要，这样能使买家在线查看他们的已发货订单的状态。如果在预计配送时间之后确认，则订单会被视为延迟发货。
如果延迟发货影响了您的整体卖家绩效，您可采取以下几个步骤来帮助您准时配送并改善您的迟发率：
仅发布您能够在预计配送时间当天或之前发货的商品。
在订单详情中提供的预计配送时间前配送订单并向亚马逊确认。
及时确认发货，以便让亚马逊和买家知道订单已发货。延迟确认发货的时间越久，忘记确认的风险便越大。未确认发货的订单将被取消，而且即使您配送了订单，也不会收到付款。了解如何确认发货。
检查您的订单配送流程，找出并解决可能导致发货延迟的任何不足之处。
在必要时调整您的处理时间，以便为买家提供切实可行的配送时间。了解更多关于处理和配送时间的信息。
使用亚马逊的配送和标签服务购买配送服务并打印装箱标签。
为关键销售期的订单量增长（如节假日期间的销量激增）做好准备。了解更多关于管理订单的信息。
如果您认为您的商品有资格获取购买按钮，请确保您有足够的库存量，以满足潜在的订单量增长。

Avoid late shipments
It’s important to confirm the shipment of your orders by the expected ship date so that buyers can see the status of their shipped orders online. An order is considered to have been shipped late when confirmation occurs after the expected ship date.
If late shipments are affecting your overall seller performance, here are some steps you can take to help you ship on time and improve your Late Shipment Rate:
List only those items you will be able to ship by or before the expected ship date.
Ship orders and confirm with Amazon by the expected ship date provided in the order details.
Confirm a shipment promptly to notify Amazon and the buyer of the shipment. The longer you delay confirming shipment, the greater the risk that you'll forget. Unconfirmed shipments will be cancelled, and even if you did ship the order, you will not be paid. Learn how to confirm shipments.
Review your order fulfillment processes to identify and resolve any deficiencies that can result in late shipments.
Adjust your handling times when necessary to provide buyers with realistic delivery times. Learn more about handling and delivery times.
Use Amazon's shipping and label services to buy shipping and print packing labels.
Be prepared for an increase in order volume during key sales periods, such as the run-up to the holiday season. Learn more about managing orders.
If you think your listing may be eligible for the Buy Box, make sure you have enough stock on hand to meet potential increases in order volumes.
