Strategic Inventory Management Framework for Big Billion Days 2025
1. Advanced Demand Forecasting
Modern demand forecasting goes beyond historical data analysis. AI-driven predictive analytics are becoming essential for accurate demand planning. Sellers should implement:
- Multi-Factor Analysis: Consider historical sales data, market trends, competitor analysis, and external factors like GST changes and festive timing.
- Category-Specific Forecasting: Fashion and beauty products are expected to capture nearly 50% of e-commerce festive spending, requiring different forecasting approaches than electronics or home appliances.
- Real-Time Adjustments: Use machine learning algorithms to continuously refine forecasts based on presale indicators, early access performance, and real-time market signals.
| Forecasting Method | Best For | Accuracy Level | Implementation Complexity |
| Historical Analysis | Established products | 70-80% | Low |
| AI-Driven Prediction | New/trending products | 85-95% | High |
| Collaborative Planning | Private label/exclusive | 75-85% | Medium |
| Market Intelligence | Competitive analysis | 80-90% | Medium-High |
2. Dynamic Safety Stock Management
The traditional safety stock formula requires enhancement for mega sales events. Consider implementing adaptive safety stock that adjusts based on:
- Lead Time Variability: Account for potential supplier delays during peak season logistics constraints.
- Demand Volatility: Use statistical models to calculate safety stock based on demand uncertainty during sales events.
- Service Level Targets: Balance investment in safety stock against target service levels and storage costs.
Enhanced Safety Stock Formula for Sales Events:
Safety Stock = √(Average Lead Time × Variance of Demand) + (Average Demand × Variance of Lead Time) × Z-score for desired service level × Sales Event Multiplier (1.5-2.5x)
3. Real-Time Inventory Intelligence
Modern inventory management systems must provide real-time synchronisation across all sales channels. Key features include:
- Dynamic Reservation Systems: Prevent overselling by reserving inventory during customer checkout processes.
- Multi-Channel Visibility: Ensure inventory updates instantly across Flipkart, your own website, and other marketplaces.
- Automated Threshold Alerts: Set up intelligent alerts that trigger reorder processes before stockouts occur.
4. SKU Optimisation and Prioritisation
Not all products deserve equal attention during Big Billion Days. Implement ABC analysis with sales velocity metrics:
- A-Category Items: High-value, fast-moving products that drive 80% of revenue. These require maximum stock availability and close monitoring.
- B-Category Items: Moderate performers that need balanced inventory investment.
- C-Category Items: Low-value items that can be bundled or offered as add-ons to increase average order value.
Performance-Based Ranking: Rank SKUs based on:
- Sales velocity during previous sales events
- Profit margins
- Supplier reliability
- Market growth trends
