+=========
+Packaging
+=========
+
+In Odoo *Inventory*, *packaging* refers to disposable containers holding multiple units of a
+specific product. Each specific packaging **must** be defined on the individual product form.
+
+For example, different packages for cans of soda, such as a 6-pack, a 12-pack, or a case of 36, need
+to be configured on the individual product form. This is because packagings are product specific —
+**not** generic.
+
+Configuration
+=============
+
+To use packagings, navigate to :menuselection:`Inventory app --> Configuration --> Settings`. Then,
+under the :guilabel:`Products` heading, enable the :guilabel:`Product Packagings` feature, and click
+:guilabel:`Save`.

+
+Create packaging
+================
+
+Packagings can be created directly on the product form, or from the :guilabel:`Product Packagings`
+page.
+
+From product form
+-----------------
+
+Create packagings on a product form by going to :menuselection:`Inventory app --> Products -->
+Products`, and select the desired product.
+
+Under the :guilabel:`Inventory` tab, scroll down to the :guilabel:`Packaging` section, and click
+:guilabel:`Add a line`. In the table, fill out the following fields:
+
+- :guilabel:`Packaging` (required): name of packaging that appears on sales/purchase orders as a
+  packaging option for the product.
+- :guilabel:`Contained quantity` (required): amount of product in the packaging.
+- :guilabel:`Unit of Measure` (required): measurement unit for quantifying the product.
+- :guilabel:`Sales`: check this option for packagings intended for use on sales orders.
+- :guilabel:`Purchase`: check this option for packagings intended for use on purchase orders.
+
+.. note::
+   Access additional fields in the :guilabel:`Packaging` table below by clicking the
+   :guilabel:`(sliders)` icon to the far-right of the column titles in the :guilabel:`Packaging`
+   section, and selecting the desired options from the drop-down menu that appears.
+
+   .. image:: packaging/slide.png
+      :align: center
+      :alt: Show the additional options menu's icon: sliders.
+
+- :guilabel:`Barcode`: identifier for tracing packaging in stock moves or pickings, using the
+  :ref:`Barcode app <barcode/operations/intro>`. Leave blank if not in use.
+- :guilabel:`Company`: indicates the packaging is only available at the selected company. Leave
+  blank to make the packaging available across all companies.
+
+.. example::
+   To create a packaging type for six units of the product, `Grape Soda`, begin by clicking
+   :guilabel:`Add a line`. In the line, name the :guilabel:`Packaging` `6-pack`, and set the
+   :guilabel:`Contained quantity` to `6`. Repeat this process for additional packagings.
+
+   .. image:: packaging/create-product-packaging.png
+      :align: center
+      :alt: Create 6-pack case for product.
+
+From product packagings page
+----------------------------
+
+To view all packagings that have been created, go to :menuselection:`Inventory app --> Configuration
+--> Product Packagings`. Doing so reveals the :guilabel:`Product Packagings` page with a complete
+list of all packagings that have been created for all products. Create new packagings by clicking
+:guilabel:`New`.
+
+.. example::
+   Two soda products, `Grape Soda` and `Diet Coke`, have three types of packagings configured. On
+   the :guilabel:`Product Packagings` page, each product can be sold as a `6-Pack` that contains 6
+   products, as a `12-Pack` of 12 products, or as a `Case` of 32 products.
+

+
+Apply packagings
+================
+
+When creating a sales order in the :menuselection:`Sales` app, specify the packagings that should be
+used for the product. The chosen packaging is displayed on the :abbr:`SO (Sales Order)` under the
+:guilabel:`Packaging` field.
+
+.. example::
+   18 cans of the product, `Grape Soda`, is packed using three 6-pack packagings.
+
+   .. image:: packaging/packagings-sales-order.png

+
+.. tip::
+   Packaging can be used in conjunction with Odoo :ref:`Barcode <inventory/barcode/software>`. When
+   receiving products from suppliers, scanning the packaging barcode automatically adds the number
+   of units in the packaging to the internal count of the product.
