The Hidden Cost of Bad Inventory Management (And How to Fix It)

Inventory problems are quietly one of the biggest margin killers in e-commerce — and most businesses don't realize how much they're losing until they run the numbers.

Stockouts vs Overstock

Stockouts cost you the sale and hand your customer to a competitor. On Amazon, a stockout on a high-velocity ASIN can take weeks to recover from in organic rank. Overstock ties up cash, creates storage fees, and forces discounting that erodes your average selling price.

The Root Cause: Reactive Ordering

Most businesses order when stock gets low. A supplier delay or demand spike turns a low-stock situation into a stockout fast.

A Simple Forecasting System

Start with a 90-day rolling average of daily sales velocity per SKU. Multiply by supplier lead time to get your reorder point. Add 10–20% safety stock for variability.

The fix: Calculate your stockout rate for the last 90 days. Work backwards to understand why and build the reorder trigger that would have prevented it.
