# Inventory Aging

> See how long your current stock has been on hand, grouped into age buckets by FIFO cost layer, with values that tie to Inventory Valuation.

<Note>
  Use **Operations > Inventory > Aging** to find stock that has been sitting too long: before a clearance or markdown review, before a write-down decision, or when cash is tied up in slow inventory. The report is read-only.
</Note>

## Before You Start

* **Permission**: you need the **reports view** permission to open the screen and run the report.
* **Location filter**: the **Location** list appears only when your company has more than one location, and it needs settings view access to load. Without that access the report still runs for all locations.
* **How age is measured**: each FIFO cost layer is aged from the day it was received. A product received on three different days has three layers, and each lands in its own bucket.

Other ways in: search for **Aging** in the command palette.

## Run the Report

1. Open **Operations > Inventory > Aging**. The report runs for today as soon as the page opens.
2. Choose the **As of date** if you want to age stock to an earlier day. Future dates are not allowed.
3. If you have more than one location, choose one in **Location**, or leave **All locations**.
4. Select **Run Report**. The button reads **Running...** while the report loads.
5. Select **Today** to return to today's aging snapshot. It is disabled while the date is already today.

<Note>
  An earlier **As of date** is not a full historical snapshot. It shows the stock you hold today from layers received on or before that date, aged to that date. For the value of inventory on a past date, use Inventory Valuation, which rewinds each layer.
</Note>

## Read the Results

**Bucket cards:** one card per age bucket, **0-30**, **31-60**, **61-90**, **91-180** and **180+ days**, each with its value and share of the total. The **180+ days** card is highlighted in red.

**Grand total inventory value:** the value of every layer in the report. Its note reads **Ties to Inventory Valuation as of (date)**: for today, the total matches the live total on the Valuation screen.

**Table columns:**

| Column               | What it shows                                                         |
| -------------------- | --------------------------------------------------------------------- |
| **Product / SKU**    | The product name and SKU.                                             |
| **Age bucket**       | The bucket the layer falls in.                                        |
| **Age range (days)** | The youngest and oldest layer age inside that bucket for the product. |
| **Qty**              | Units still remaining in those layers.                                |
| **Value**            | Remaining units times their layer cost.                               |
| **% of total**       | The row's share of the grand total.                                   |

## Common Scenarios

* **Clearance review**: run for today and focus on the **91-180** and **180+ days** buckets.
* **Write-down decision**: compare the old buckets with Dead Stock to see whether old stock is also not moving.
* **One warehouse**: choose the location to see only the stock aging there.

## What This Report Does Not Change

Running the report is read-only. It posts nothing to the ledger, moves no stock, and sends no notifications.
