Direct answer
What is Stockout?
A stockout occurs when available inventory for a SKU reaches zero while demand still exists. Stockouts cost revenue and can damage paid media efficiency, marketplace ranking, and repeat purchases. Prediction before the event matters more than an alert at zero.
Practical example
Stock lasts nine more days, but the next confirmed delivery arrives in 16 days. The system predicts seven stockout days.
