# Out of Stock

> Items currently out of stock and the revenue they're costing you

The **Out of Stock** report lists items that have hit zero available, with an estimate of the sales you're missing while they're unavailable.

**Key columns**: product, variant, SKU, location, days out of stock, last in-stock date, average daily sales, and estimated lost revenue.

**Estimated lost revenue** is based on the item's recent sales rate multiplied by how long it's been out and its typical price - a way to prioritise which stockouts to fix first.

**When to use it**: to triage restocks by impact rather than alphabetically - the items at the top are the ones quietly costing you the most.
