Direct Answer: When selling across multiple platforms like Amazon, Rakuten, and TikTok Shop, an Order Management System (OMS) is essential for unified operations. DONOMI utilizes modern tech stacks like Next.js and Cloudflare to build an OMS that centralizes orders, automates inventory synchronization, and optimizes shipping workflows. By integrating directly with platform and carrier APIs, this system overcomes platform-specific challenges and provides real-time visibility into sales and profits across all channels.
