# The part catalogue

> Spare parts and consumables across stores, with stock levels and shortage warnings.

Every part you hold, with what is on hand across all your stores.

## Stock across stores

The catalogue totals stock across warehouses. But **"at or below reorder point" is asked per
store**, not against the total — because one store being empty is the fact worth surfacing.
Totalling would hide a shortage at the plant behind stock sitting in another building.

So a part can show healthy total stock and still be flagged: the store that needs it has none.

## Columns

| Column            | Notes                                             |
| ----------------- | ------------------------------------------------- |
| **Part number**   | Your identifier — click to open                   |
| **Description**   | What it is                                        |
| **Category**      | From your [inventory settings](/config/inventory) |
| **On hand**       | Total across all stores                           |
| **Reserved**      | Held for jobs, not available                      |
| **Available**     | On hand minus reserved                            |
| **Reorder point** | The level that triggers a recommendation          |

## Reserved against available

Reserving a part for a job holds it so another job cannot take it. **Available** is what you can
actually promise to a new job — which is the number that matters when readiness asks whether a job
can proceed.

## Adding a part

## Where parts get used

* **On a job.** Parts are reserved as requirements and consumed when issued. See
  [the work order](/work/work-order-detail).
* **From a maintenance plan.** Every round of a plan carries the parts it consumes, which is what
  lets demand be forecast rather than discovered.
* **On an asset's BOM.** Which parts fit which machine, so "which filter does P-102 take" is
  answerable at the counter.
