BigSeller Multichannel Sales Management

BigSeller is a multichannel e-commerce management platform launched in 2019 for Southeast Asian online sellers by the team behind the cross-border ERP dianxiaomi, under the Shenzhen-based group Meiyunji. It tackles the work of running stores on several marketplaces at once, where listings, orders and stock quickly drift out of sync.

Sellers connect stores from more than 20 platforms, including Shopee, Lazada, TikTok Shop, Tiki and Sendo in Vietnam, then manage products, orders, inventory and purchasing in one interface. Modules cover product copying between stores, marketing tools, distribution management, warehouse operations, a POS for physical shops, live selling, data reports and a mobile app. The platform targets individual sellers, brands and e-commerce teams and has local offices in Vietnam, Indonesia, Thailand, Malaysia and the Philippines.

• Order management: Processes orders from all connected marketplaces in one queue.
• Inventory sync: Updates stock across stores and warehouses automatically.
• Product copying: Copies listings from one store or platform to another in bulk.
• Warehouse and purchasing: Manages inbound stock, picking and purchase orders.
• BigSeller POS: Brings offline shop sales into the same stock and order data.
• Data reports: Tracks sales, profit and store performance across channels.

A cosmetics distributor can manage stores on Shopee, Lazada and TikTok Shop with one shared stock pool. A fashion brand can copy new collections to all its marketplace stores in bulk. A household goods seller can link its offline shop through BigSeller POS to avoid selling items already sold in store.

Sellers can start with a free sign-up and upgrade to paid plans as volume grows. One dashboard replaces logging into each marketplace separately, and stock syncs across stores to reduce overselling. BigSeller reports more than 1,100,000 sellers and over 300 million orders processed per month, which indicates stability under high peak volumes. Local offices in Hanoi and Ho Chi Minh City provide Vietnamese support and training.

E-commerce in Vietnam and Southeast Asia is spread across Shopee, Lazada, TikTok Shop and local platforms, and sellers increasingly run several stores plus a physical shop. Rising order volumes, platform fee changes and live commerce push sellers toward ERP-style tools that keep catalog, stock and orders consistent.
