We pair warehouse operations and technology with firsthand eCommerce experience.
Founded on January 1, 2026, in Ontario, California, Harmony Global USA was created to make fulfillment, inventory management, and shipping easier for eCommerce businesses.
In addition to providing fulfillment services, we operate our own online stores across major marketplaces including TikTok Shop and Temu. That means our warehouse processes are continuously informed by real seller needs.
Our goal is simple: help business owners focus on products, sales, and customers while we manage the fulfillment operation behind the scenes.
Growing businesses use our warehouse infrastructure and WMS-supported workflows without building an operation from scratch.
Our marketplace stores give us direct exposure to inventory, order processing, shipping cost, returns, and customer expectations.
We experience the same operational pressures that matter to sellers.
Daily order, inventory, shipping, and returns work reveals what needs attention.
Insights are translated into clearer warehouse workflows and customer solutions.
Whether a business is processing its first few hundred orders or preparing to scale to thousands per month, we aim to provide the infrastructure, technology, and operational support needed to grow efficiently.
Let’s build one connected fulfillment solution.
