OOS

Out of Stock

Terms, metrics, and workflows around Amazon Seller, Vendor, and Marketplace operations.

What it means

OOS (Out of Stock) means a product is currently unavailable. Frequent OOS periods damage sales rank, reduce visibility, and frustrate customers who turn to competitors. Amazon displays an 'Currently unavailable' label during prolonged OOS periods. Sellers should strategically time reorders to minimize stockouts and ensure continuous availability.
