A growing e-commerce seller operated across Tokopedia, Shopee, Lazada, TikTok Shop, and a Shopify storefront with 4,000+ SKUs. Inventory drift was constant: oversells, stockouts on listed-as-available items, and 6+ hours per day spent manually syncing stock across platforms.
We built a central inventory and order hub that talks to each marketplace via their official APIs. Stock is reconciled every 2 minutes, orders flow into a single fulfillment queue, and the warehouse team scans a barcode to mark items shipped, which updates every marketplace simultaneously. A dashboard shows real-time channel performance, fast-movers, and dead stock by warehouse.
Oversells dropped from around 30 per month to under 3. The 6 daily hours of inventory syncing became 15 minutes of exception review. The seller scaled SKUs by 60% in 6 months without adding warehouse headcount.
