What is Reorder Point (ROP)?
Understanding Reorder Point (ROP) in E-commerce
Quick Definition
Reorder Point (ROP) is an inventory management metric that determines the minimum stock level at which a new order should be placed to prevent stockouts. It considers lead time, average daily sales, and safety stock to ensure continuous product availability without overstocking. ROP helps businesses maintain optimal inventory levels and minimize holding costs while preventing lost sales opportunities.
Understanding Reorder Point (ROP)
ROP Calculation Formula
ROP = (Average Daily Sales × Lead Time) + Safety Stock
Example Calculation:
- Average Daily Sales: 20 units
- Lead Time: 14 days
- Safety Stock: 50 units
- ROP = (20 × 14) + 50 = 330 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
- •Enhances Customer Satisfaction: Maintains consistent product availability
Key Components of ROP
