A free supply chain tools platform built for Amazon sellers and e-commerce professionals
Stow Stream stems from a deep understanding of e-commerce operations. As an e-commerce operations manager achieving $560,000 USD in monthly revenue, I know firsthand the challenges every seller faces in supply chain management: complex freight calculations, inventory management difficulties, and unclear profit margins.
In 2025, I decided to transform a decade of operational experience into practical technical tools. We began building solutions that could truly solve sellers' daily pain points, from simple calculators to complete supply chain optimization systems.
Today, we proudly offer a suite of free tools that help sellers optimize supply chains, reduce costs, and grow their businesses. Every feature embodies practical experience, and every design originates from real needs.
