Inventory Tracking

Overview

Real-time inventory tracking prevents overselling by reserving stock when customers add items to their cart and decrementing it on order fulfillment. Every major e-commerce platform has this built in. Platform-native inventory tracking is almost always the right starting point — only build custom inventory logic if you have requirements that platforms cannot meet (complex multi-warehouse routing, custom reservation windows, or external WMS integration).

When to Use This Skill

• When overselling is occurring and orders are being placed for out-of-stock items
• When implementing multi-warehouse inventory with per-location stock levels
• When building backorder or pre-order functionality for out-of-stock products
• When a flash sale or product launch will create high-concurrency checkout attempts for limited-stock items
