Key features include order management capabilities such as shipping, canceling, and processing refunds, all accessible from anywhere at any time. Users can also preview their listings and adjust prices before publication, ensuring their offerings are competitive and appealing to customers.

Additionally, the app provides essential communication tools, including push notifications for updates and the ability to interact with customers. Sellers can track their sales performance through a Sales Tracker, gaining insights into revenue growth. The app also supports management of Walmart Fulfillment Services (WFS) orders, allowing users to monitor their inventory and shipments effectively.
