# Available

> Your projected available (sellable) inventory at the start and end of each period

## What it tells you

Available is your projected **available (sellable) inventory** — the on-hand balance you expect to have that you can actually use to meet demand. It appears at the **start** and **end** of each period on the [Supply planning](/guide/supply-planning/overview) grid, so you can see how the balance moves as demand and supply play out.

By default it shows as a quantity. If you set **Display numbers in → Value**, it shows as currency instead.

## How to read it

For a sellable location, the cell color tells you how the projected balance sits against demand and your **safety stock** (the buffer you want to keep on hand):

| Color  | What it means                                        |
| ------ | ---------------------------------------------------- |
| Red    | Zero available while demand still exists that period |
| Orange | Positive but under safety stock                      |
| Gray   | Zero, with no demand that period                     |

You can expand an **Available - start** cell to see a **per-warehouse breakdown**, which groups your stock into buckets so you can see not just how much you have, but whether it can actually serve demand:

* **Sellable** — inventory that can meet demand
* **Supplier sites** — stock held at supplier locations
* **Pass through** — stock moving through on its way elsewhere
* **Stranded** — inventory that exists but is in the wrong place to serve demand
* **Irrelevant** — stock that does not count toward this product's availability

A yellow **"S"** marker flags **stranded stock**: inventory that physically exists but cannot serve demand because it is in the wrong location. Stranded stock usually calls for a transfer to move it where it is needed.

## What to do about it

* Watch where the projected balance dips toward or below safety stock (orange), and line up supply before it hits zero (red).
* When you see the yellow **"S"** marker, move that stranded stock to a location that can use it with a [transfer](/transfers).

## Example

A warehouse shows **Available - start** of 0 in red while demand for the period is positive — a projected stockout. Expanding the cell reveals plenty of stock sitting under **Stranded** at another site, marked with a yellow **"S"**. The fix is not a new order but a transfer to bring that stranded stock to where the demand is.

> **Tip:** Available is the inventory behind your coverage metrics — pair it with [DOS](/dos) to read coverage, use [Transfers](/transfers) to move stranded stock, and check [Shortage](/shortage) when a red cell signals unmet demand.
