# Category management

Category management is running a group of related products as one business, with one owner accountable for its range, pricing, promotions and suppliers.

Also called: catman

- **Is:** Running a group of related products as one business, with one accountable owner.
- **Decides:** Range, price, promotion and supplier terms together, judged on the category total.
- **Watch for:** A line that wins on its own numbers while the category loses.

## What it means for retail and category teams

For a retail or category team, the unit of decision is the whole category. A category manager weighs a price move, a new listing or a promotion by what it does to the whole shelf: which lines lose sales to it, how it shifts the margin mix, and which supplier terms it affects.

## Why it matters

When every line is judged on its own numbers, the category ends up in a shape nobody planned. A promotion that lifts one brand can cost more margin across its neighbours than it earns, and a delisting that looks tidy on a sales report can strand the shoppers who came for it. Managing the category as a whole makes those trade-offs visible before they are made.

## Illustrative example

The business and figures are illustrative. None of it is customer data.

A laundry care category manager is offered supplier funding to sell a leading 2 L liquid at half price for two weeks. In a normal fortnight it sells 400 units at $6 gross profit each; on promotion the forecast is 1,600 units at $2 each after funding, so the line earns $3,200 instead of $2,400. Over the same fortnight the own-label liquid is expected to fall from 500 to 200 units at $5 each, and powders from 300 to 200 at $4. Category units rise from 1,200 to 2,000, and category gross profit falls from $6,100 to $5,000.

**Laundry care gross profit over two weeks**

| | Normal fortnight | Half-price promotion | Result |
| --- | --- | --- | --- |
| Leading liquid, 2 L (promoted) | $2,400 | $3,200 | +$800 |
| Own-label liquid, 2 L | $2,500 | $1,000 | −$1,500 |
| Powders | $1,200 | $800 | −$400 |
| Category total | $6,100 | $5,000 | −$1,100 |

The promoted line earns $800 more. The category earns $1,100 less.
