Frequently asked questions
How accurate is this stockout cost estimate?
This is a conservative estimate based on industry research. The actual cost is often higher when you factor in long-term customer churn (9% of customers never return after one stockout), ranking drops on Amazon and Google Shopping, and wasted ad spend driving traffic to unavailable products.
What percentage of shoppers leave when an item is out of stock?
Research consistently shows 69% of online shoppers will go to a competitor when an item is out of stock. Only 9% will wait for the item to come back in stock. The remaining 22% will substitute with another product on your site.
How do I reduce stockouts?
The key steps are: (1) Set reorder points for each SKU based on lead time and daily sales, (2) Monitor inventory daily, (3) Place orders before you hit the reorder point — not after. Reorderly automates all three steps.
Are stockout costs tax deductible?
No — stockout costs are opportunity costs (revenue you didn't earn), not an expense. They don't appear on your P&L, which is why many merchants underestimate them.
