Walmart UK Seller Summit 2025: WhatSales Recap

The Walmart UK Seller Summit 2025 in London brought together hundreds of sellers, partners, and innovators. The event created opportunities for collaboration, learning, and growth across the ecommerce landscape.

WhatSales was proud to be the only profitability and performance provider for Walmart sellers at the summit. Our stand quickly became one of the busiest, with sellers eager to learn how our platform brings clarity and transparency to online selling.

Attendees were particularly interested in WhatSales’ ability to tackle critical challenges such as inventory management, stockouts, refunds, and loss forecasting. By showing sellers exactly how much issues like refunds and stockouts cost them each month, we helped highlight where action is needed to protect revenue and improve margins.

By factoring in refunds, replacements, ad spend, and seasonal trends, WhatSales automates inventory rules and reduces the risk of going out of stock. Sellers can protect revenue and maintain growth with smarter forecasting.
