Just-in-Time Inventory Replenishment by Product Variant

Overview

This report provides detailed insights into your inventory, focusing on Just-in-Time (JIT) replenishment for each product variant. It helps in optimizing inventory levels, reducing carrying costs, and ensuring product availability.


Key Terms

  • SKU: Stock Keeping Unit, a unique identifier for your product variants.
  • Vendor Lead Time: Time taken by the supplier to deliver products after an order is placed.
  • Safety Stock Days: The buffer stock to prevent stockouts.
  • Units Sold in Historical Period: Total sales of a product variant in a specified period.
  • Avg Units Sold per Day: Daily average sales for each product variant.
  • Quantity On-hand: Current stock levels of each product.
  • Incoming Inventory: Ordered stock that is yet to be received.
  • Days of Inventory Remaining: Estimated time until the current stock runs out.
  • Reorder Point: The stock level at which a new order should be placed.
  • Reorder Quantity: Suggested quantity to order at the reorder point.
  • Unit Cost: Cost per individual unit.
  • Reorder Cost: Total cost for reordering the suggested quantity.


Formulas for Reorder Point and Reorder Quantity

  • Reorder Point: Calculated as [Average Units Sold per day] x ([Vendor Lead Time] + [Safety Stock Days]). This is the inventory level at which you should trigger a new order.
  • Reorder Quantity: When the 'Quantity On-hand' falls below the Reorder Point, the reorder quantity is equal to the Reorder Point. If the on-hand quantity is higher than the Reorder Point, no replenishment is suggested.


Using the Report

  1. Monitor Stock Levels: Check the 'Quantity On-hand' and 'Days of Inventory Remaining' to understand current stock status.
  2. Identify Replenishment Needs: Use the Reorder Point formula to determine when to reorder and the Reorder Quantity to know how much to order.
  3. Plan Purchases: Use 'Reorder Quantity' and 'Reorder Cost' to plan your inventory purchases both in terms of quantity and budget.
  4. Evaluate Sales Performance: 'Units Sold in Historical Period' and 'Avg Units Sold per Day' provide insights into the sales performance of each product variant.
  5. Manage Supplier Relations: 'Vendor Lead Time' helps in planning orders considering the time it takes for products to be delivered.


Tips for Effective Management

  • Regularly review the report to stay ahead of inventory needs.
  • Coordinate with suppliers for products with high sales velocity or long lead times.
  • Adjust safety stock levels based on sales trends and seasonality.
  • Use the data to negotiate better terms with suppliers, like reduced lead times or bulk purchase discounts.


Conclusion

This report is a powerful tool for maintaining optimal inventory levels, avoiding overstocking or stockouts, and ensuring customer satisfaction through product availability.
