EFEX is a Vietnam-born e‑commerce fulfillment and cross‑border shipping provider. Over the past decade, it’s grown from local 3PL services into an end‑to‑end operation—warehousing, pick/pack, delivery, returns, and customs—serving merchants across Southeast Asia with extensions into Japan and the U.S. Merchants manage orders, inventory, and tracking through EFEX’s cloud OMS and support desk.
