# ABC Analysis

> Classify products into A, B, and C tiers by revenue contribution

The **ABC Analysis** report ranks your products by revenue and groups them into tiers, so you can see which items truly drive the business (and which barely move the needle).

**Key columns**: product, variant, SKU, ABC class, revenue, revenue percentage, and cumulative percentage.

* **A** items are your top revenue drivers (roughly the first 80% of cumulative revenue)
* **B** items are the next tier
* **C** items contribute the least

**When to use it**: to focus your attention - tighter stock control and service levels on A items, less effort on C items.
