What is a ROP (Reorder Point)?
Understanding ROP (Reorder Point) in E-commerce
Quick Definition
Reorder Point (ROP) is an inventory management metric that indicates the stock level at which a new order should be placed to replenish inventory. It balances anticipated demand during lead time with safety stock, preventing stockouts while minimizing excess inventory holding costs. ROP helps businesses maintain optimal inventory levels and ensure continuous product availability.
Understanding Reorder Point (ROP)
ROP Calculation Formula
ROP = (Average Daily Usage × Lead Time) + Safety Stock
Example Calculation:
- Daily Product Sales: 50 units
- Supplier Lead Time: 14 days
- Safety Stock: 100 units
- ROP = (50 × 14) + 100 = 800 units
Why ROP Matters for E-commerce
- •Prevents Stockouts: Ensures continuous product availability
- •Reduces Holding Costs: Minimizes excess inventory investment
- •Improves Cash Flow: Optimizes inventory spending and working capital
- •Supports Demand Forecasting: Provides strategic inventory management insights
