What You Can Do

You can upload historical sales data and inventory records to receive data-driven replenishment recommendations. Your analysis leverages demand pattern detection, lead time adjustment, and cost optimization to calculate optimal reorder points and safety stock levels that balance carrying costs against stockout risk. You'll get actionable strategies tailored to your business, including reorder frequencies, optimal order quantities, and alerts for unusual demand shifts.

Features

Demand Pattern Analysis

Identifies trends, seasonal cycles, and anomalies in your historical sales data to create accurate demand forecasts

Optimal Reorder Point Calculation

Computes the precise inventory level that triggers reordering based on lead time, consumption rate, and safety margins

Safety Stock Recommendations

Calculates minimum buffer stock needed to cover demand variability and prevent stockouts during supply disruptions

Economic Order Quantity (EOQ)

Balances ordering costs against holding costs to recommend the most cost-efficient order sizes

Lead Time Integration

Accounts for supplier lead times in reorder calculations to ensure stock arrives before depletion

Seasonal Adjustment

Detects seasonal demand patterns and adjusts strategies accordingly for holiday peaks or off-season troughs

Multi-SKU Coordination

Manages replenishment across multiple products simultaneously while respecting budget and storage constraints

Cost-Benefit Analysis

Evaluates inventory carrying costs, order costs, and stockout penalties to find the optimal balance for your business

Example Output

Reorder Analysis for SKU-4521:

Current Demand: 150 units/week (variance: 25 units) Lead Time: 2 weeks Recommended Reorder Point: 425 units Optimal Order Quantity: 800 units Safety Stock Buffer: 150 units Projected Inventory Turns: 6.2x annually Annual Carrying Cost: $2,100 (vs $3,400 current)

Recommendation: Shift from monthly to bi-weekly ordering. Expected savings: $1,300/year (38% reduction).


Seasonal Q4 Adjustment:

Nov-Dec demand spike detected (45% increase). Increase reorder point to 550 units starting Sept 15. Revert to 425 units Jan 2. Pre-position additional safety stock by early October.
