OneCart Multichannel Ecommerce Management

OneCart is a multichannel management system for online sellers operated by Lachmann Technologies Pte. Ltd. in Singapore. It addresses the overselling, manual order handling and scattered listings that brands face when selling across Shopee, Lazada, TikTok Shop, Amazon and their own web stores.

The platform combines an inventory management system with real-time stock sync, an order management system for consolidated picking, packing and pickup booking, and catalogue management for one-click cross-listing. An AI Agent for Ecommerce and an Ecommerce Health Check sit on top. It connects to more than 20 marketplaces across Southeast Asia, Australia, the UK, Europe and North America, as well as Shopify, WooCommerce, Magento and ERPs such as NetSuite, SAP Business One, Dynamics 365 and Odoo.

• Inventory sync: Updates stock across all connected channels in near real time.
• Order management: Consolidates orders with picking lists, packing lists, printing and pickup booking.
• Listing management: Cross-posts products to several marketplaces in one click.
• Price segmentation: Sets different prices for the same SKU on different channels.
• Analytics and reports: Provides sales dashboards and reports-only plans for high order volumes.
• AI Agent and API: Adds an AI agent tier and a standard API for ERP integration.

A cosmetics distributor selling on Shopee, Lazada and TikTok Shop Vietnam can sync stock from one warehouse to avoid overselling on mega sale days. A fashion brand can push new collections to several marketplaces at once with channel-specific prices. A consumer goods company can feed marketplace orders into its SAP Business One or Odoo ERP.

Stock levels update across channels, with a claimed sync time of about five seconds, which reduces overselling during sale campaigns. Orders from every marketplace are processed in one queue with batch printing and courier pickup. OneCart says users save 15 to 40 hours per week. Per-channel pricing for the same SKU and a full audit trail of price and quantity changes give better control.

Sellers in Southeast Asia now split sales across Shopee, Lazada, TikTok Shop and their own stores, and peak events such as 11.11 multiply order volumes in a few hours. This drives demand for central inventory and order tools. In Vietnam, where TikTok Shop has grown quickly alongside Shopee and Lazada, brands and distributors need multichannel software that connects to ERP and accounting systems.
