Optimized seller-set transit

What is the optimized seller-set transit feature?

The optimized seller-set transit (OST) feature helps provide faster and more accurate delivery times to customers for seller-fulfilled standard shipping orders with just a single click. This feature uses historical carrier shipping data to dynamically adjust your transit times based on your default warehouse location and the customer location. This allows you to provide more accurate estimated delivery times to customers, while using your carrier of choice.

Note: Currently, the optimized seller-set transit feature is available to Sellers on an invitation-only basis.
Note: The optimized seller-set transit feature uses your default shipping warehouse location (default shipping address) and customer location to estimate transit times. Please ensure that your default shipping address is up to date (see below for more details).

How can I enable the optimized seller-set transit feature?

To enable the optimized seller-set transit feature, please follow the below steps:

  1. From the Settings drop-down menu on the top right of Seller Central, click Shipping Settings.
  2. On the Shipping Settings page, navigate to Shipping templates.
  3. To enable the optimized seller-set transit feature for an existing shipping template, click Edit template and scroll down to Optimized seller-set transit and turn on the toggle button.
  4. To enable the optimized seller-set transit feature for a new template, click Create a new shipping template and scroll down to Optimized seller-set transit and turn on the toggle button.
  5. Click Save to apply your changes to the shipping template.
Note: The optimized seller-set transit feature is limited to seller-fulfilled standard shipping settings only.

What is the benefit of enabling the optimized seller-set transit feature?

Customers love faster deliveries and are more likely to purchase products that have shorter estimated delivery times. Products with shorter estimated delivery times are also more likely to be the featured offers on product detail pages. By enabling the optimized seller-set transit feature in your shipping templates, you will have an opportunity to provide faster and more accurate delivery times to customers.

How do I edit my default shipping address?

You can edit your default shipping address by performing the following steps:

  1. Click Settings > Shipping Settings > General Shipping Settings
  2. Click Edit in the top-right corner of the Default shipping address section
  3. Select the address that you want to set as the new default shipping address, or click Add a new address to add a new ship-from address
  4. Click save

Do I need to re-enable the optimized seller-set transit feature on my shipping templates every time I update my default shipping address?

No. It is not necessary to opt in to the optimized seller-set transit feature on shipping templates where you have SSA enabled.

How can I opt out of the optimized seller-set transit feature?
