🧮 Calculation Logic
📦 Inventory Accuracy Savings
Reduces inventory shrinkage through better tracking and serialization.
Formula:
Components:
- • Inventory Value at Cost = Inventory Count × Cost Price
 - • Cost Price = Average Selling Price × (1 - Gross Margin %)
 - • Shrinkage Reduction = 1.5% (configurable)
 
Business Impact:
- • Reduces inventory losses
 - • Improves stock accuracy
 - • Better demand forecasting
 
👷 Labor Cost Savings
Reduces manual processing time through automation and optimized workflows.
Formula:
Components:
- • Annual Orders = Daily Orders × 365
 - • Time Saved = 6 minutes per order (configurable)
 - • Labor Cost = ₹85/hour ÷ 60 = ₹1.42/minute
 
Business Impact:
- • Faster order processing
 - • Reduced labor costs
 - • Higher throughput capacity
