Optimized seller-set transit

What is Optimized seller-set transit feature?

Optimized seller-set transit (OST) can help provide faster and more accurate delivery times for seller-fulfilled standard shipping orders. This feature uses historical carrier shipping data to dynamically adjust the transit times between your default warehouse location and the customer location. Enabling this option on your standard shipping template can help you provide more accurate estimated delivery promise to customers, while using your carrier of choice.

Currently, the OST feature is available to sellers on an invitation-only basis.

Important: Ensure your default shipping address is up to date, as OST uses your default shipping warehouse location (default shipping address) and customer location to estimate transit times. You can refer to the FAQ section on this page to learn more on how to update your default ship-from address.

How to enable the OST feature

To enable the OST feature, follow the steps below:

  1. Under Settings on Seller Central, click Shipping settings.
  2. On the Shipping Settings page, navigate to Shipping templates.
  3. To enable the OST 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 OST 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: OST feature is limited to seller-fulfilled standard shipping settings only.

Optimized seller-set transit FAQ

What is the benefit of enabling OST?

Customers like faster deliveries and are more likely to purchase products that have faster estimated delivery times. Products with faster estimated delivery times are also more likely to be the featured offers on product detail pages. By enabling the OST feature in your shipping templates, you will have an opportunity to provide more accurate (and as a result, faster) delivery times to customers.

Do I need to re-enable OST on my shipping templates every time I update my default shipping address?

No. Once you have enabled optimized seller-set transit on your shipping templates, Amazon will automatically use your latest default shipping address to estimate delivery times for the customers. You do not need to re-enable it on your shipping templates after you have changed your default shipping address.

How do I edit my default shipping address?

You can edit your default shipping address by following these steps:

  1. Click Settings drop-down menu on the top right of Seller Central.
  2. Click Shipping settings. On the Shipping settings page, navigate to General shipping settings.
  3. Click Edit on the top right corner of the Default shipping address section.
  4. 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.
  5. Click Save.

Can I opt-in to OST in a standard shipping template where I have also enabled Shipping settings automation (SSA)?

No. It is not necessary to opt in to OST feature on shipping templates where you have SSA enabled.

How can I opt out of OST feature?

You can opt out anytime by turning off the Optimized seller-set transit toggle button on your shipping templates.

If I have opted out, can I opt back in?

Yes. You can opt back in anytime by turning on the Optimized seller-set transit toggle button on your shipping templates.
