Reorder Point

What is Reorder Point?

A reorder point is the inventory level at which you should place a new purchase order to replenish stock before it runs out. It's calculated based on your average sales velocity and the lead time required to receive new inventory from your supplier. This threshold ensures you maintain adequate stock to fulfill customer orders while minimizing excess inventory.

Why it matters for Shopify brands

For ecommerce businesses, stockouts are costly—they result in lost sales, disappointed customers, and potential damage to your brand reputation. Conversely, overstocking ties up capital and increases storage costs. A well-defined reorder point strikes the perfect balance, ensuring consistent product availability without unnecessary inventory buildup. This is especially critical for brands managing multiple SKUs across fast-moving consumer goods, where timing directly impacts profitability.

Key facts about Reorder Point

• Formula basics: The standard reorder point formula is (Average Daily Sales × Lead Time in Days) + Safety Stock. This accounts for both predictable demand and unexpected fluctuations.
• Lead time is critical: The longer your supplier's lead time, the higher your reorder point must be. A 30-day lead time requires a significantly larger safety buffer than a 5-day lead time.
• Seasonality affects calculations: Reorder points should be adjusted seasonally. Peak sales periods require higher thresholds, while slow seasons allow for lower safety stock levels.
• Safety stock varies by risk tolerance: Brands prioritizing service levels maintain higher safety stock, while cost-conscious operations may accept occasional stockouts to reduce carrying costs.

Common mistakes to avoid

• Using static reorder points: Setting one reorder point and never adjusting it ignores seasonal trends, supplier changes, and shifts in customer demand patterns. Review and update your thresholds quarterly.
• Ignoring lead time variability: Suppliers don't always deliver on schedule. Failing to account for potential delays—especially with international suppliers—leaves you vulnerable to stockouts.
• Neglecting safety stock: Some brands calculate the minimum reorder point but skip safety stock entirely. This single-point calculation offers no buffer for demand spikes or supply delays, increasing stockout risk significantly.
