Active Inventory - USAE-commerceSaaS Application2 Resources4 months + enhancements

## What business challenges did we solve?

-   •
    
    **Amazon Data Complexity:** Sales, inventory, and shipment data needed to be synced for real-time AI recommendations.
    
-   •
    
    **Inventory Volatility:** Rapid changes in FBA stock levels and delays in Amazon reporting required predictive buffer strategies.
    
-   •
    
    **Demand Forecasting Accuracy:** Seasonality and product lifecycle trends needed to be accounted for to avoid overstock or stockouts.
    
-   •
    
    **Procurement Logic:** Mapping forecasted demand to vendor-specific purchase rules and MOQ constraints was non-trivial.
    
-   •
    
    **Scalability:** The system had to support thousands of SKUs across multiple Amazon marketplaces without performance degradation.
