+## Stocktake Exporter Plugin
+
+The **Stocktake Exporter Plugin** provides custom "stocktake" export functionality for [Part](../../part/index.md) data.
+
+It utilizes the [ExporterMixin](../mixins/export.md) mixin to provide a custom export format for stocktake data.
+
+This exporter plugin can be used to export a comprehensive list of current stock levels for selected parts.
+
+### Activation
+
+This plugin is an *optional* plugin, and must be enabled in the InvenTree settings.
+
+### Plugin Settings
+
+There are no configurable settings for this plugin.
+
+## Usage
+
+This plugin is used in the same way as the [InvenTree Exporter Plugin](./inventree_exporter.md), but provides a custom export format for stocktake data.
+
+### Export Options
+
+When exporting part data, the *Stocktake Exporter* plugin is available for selection in the export dialog. When selected, the plugin provides some additional export options to control the data export process.

+| Option | Description |
+|--------|-------------|
+| `Pricing Data` | Include pricing data in the export. This will add columns for the cost of "stock on hand". |

+| `Include Variant Items` | Include variant items in the export. This will add columns for the variant items associated with each part, and include the variant quantities in the total stock count and valuation. |
