# Profit / COGS

> Profit and cost of goods sold by product and location

The **Profit / COGS** report breaks down revenue, cost of goods sold, and gross profit for the period, so you can see which products and locations actually make money.

**Key columns**: product, variant, SKU, location, units sold, total revenue, total COGS, gross profit, and profit margin.

**When to use it**: to find your most and least profitable lines - high revenue doesn't always mean high profit once cost of goods is accounted for.

<Tip>
  Accurate profit depends on unit costs. Use the [Health Check](/user-guide/health-check) to find products missing a cost.
