About the Company

Tailor

Headless ERP platform for omnichannel retail

Tailor provides a headless ERP platform for modern retail and e‑commerce brands. It runs as a composable, API‑first backend that handles inventory, supply chain, purchasing, production, accounting, and omnichannel orders, while the frontend is decoupled and can use Tailor’s modules or custom interfaces; it also integrates with 50+ tools via APIs/GraphQL. Unlike monolithic ERP systems, Tailor offers a lightweight, flexible headless architecture for DTC and B2B brands with light manufacturing, enabling rapid customization and easy tool connections. Its goal is to help fast-growing retailers automate operations and adapt quickly to market changes, with plans to expand in North America and continue product development including AI features.
