Suppliers can manage their shipping times under the Edit Profile > Dropshipping tab.
We have added Shipping Times to provide retailers an understanding of when items will be delivered. You are required to fill in estimated delivery times based on the carriers you use. These times will be visible to all retailers so they should be as accurate as possible.
The tracking number you provide once a shipment has been sent will have the most accurate information, however estimates are meant to provide retailers with an understanding of times before an order is placed.
