What is Long tail SKUs?

Long tail SKUs matter because they are easy to mismanage. A small store owner can spend as much time reordering a slow scent that sells twice a month as a bestseller that sells fifty times a month, but the payoff is much smaller. Left unchecked, the long tail quietly ties up cash in stock that barely moves.

The fix is not to delete every slow seller. It is to order long tail SKUs in smaller, less frequent batches and watch them for signs they should be discontinued. Reviewing sales by SKU every few months helps separate long tail products worth keeping from ones that are becoming dead stock.

Example

A candle store has 60 SKUs. Its top 5 scents sell 400 units a month combined. The other 55 scents each sell 1 to 4 units a month, totaling 120 units. Those 55 slow sellers are the long tail. They add variety but each one is hard to forecast and easy to overstock or run out of at the wrong time.

Common mistakes

• Ordering long tail SKUs in the same large case packs as bestsellers, leading to years of stock for a slow seller.
• Ignoring long tail SKUs in forecasting and treating all products as equally predictable.
• Letting a long tail grow without review, so dead stock piles up across dozens of low-selling variants.
