Apply inventory adjustments with barcodes
=========================================

In a warehouse, the recorded inventory counts in the database might not always match the actual,
real inventory counts. In such cases, inventory adjustments can be made to reconcile the
differences, and ensure that the recorded counts in the database match the actual counts in the
warehouse. In Odoo, the *Barcode* app can be used to make these adjustments.

These adjustments can be done in real time using an Odoo-compatible barcode scanner or the Odoo
mobile app.

.. note::
   For a list of Odoo-compatible barcode mobile scanners, and other hardware for the *Inventory* and
   *Barcode* apps, refer to the `Odoo Inventory • Hardware page
   <https://www.odoo.com/app/inventory-hardware>`_.

Enable Barcode app
==================

To use the *Barcode* app to create and apply inventory adjustments, it **must** be installed by
enabling the feature from the settings of the *Inventory* app.

To do so, go to the :menuselection:`Inventory app --> Configuration --> Settings`. Then, scroll down
to the :guilabel:`Barcode` section, and click the checkbox next to the :guilabel:`Barcode Scanner`
option.

Once the checkbox is ticked, click :guilabel:`Save` at the top of the page to save changes.

After saving, a new drop-down menu appears under the :guilabel:`Barcode Scanner` option, labeled
:guilabel:`Barcode Nomenclature`, where either :guilabel:`Default Nomenclature` or
:guilabel:`Default GS1 Nomenclature` can be selected. Each nomenclature option determines how
scanners interpret barcodes in Odoo.

There is also a :guilabel:`Configure Product Barcodes` internal link arrow, along with a set of
:guilabel:`Print` buttons for printing barcode commands and a barcode demo sheet.

   <../setup/software>` docs.

Perform an inventory adjustment
===============================

Begin by navigating to the :menuselection:`Barcode app --> Barcode Scanning` dashboard, where
different options will be displayed, including :guilabel:`Operations`, :guilabel:`Inventory
Adjustments`, and :guilabel:`Batch Transfers`.

To create and apply inventory adjustments, click on the :guilabel:`Inventory Adjustments` button at
the bottom of the screen.

Doing so navigates to the *Barcode Inventory Client Action* page, labeled as :guilabel:`Inventory
Adjustment` in the top header section.

.. image:: adjustments/adjustments-barcode-scanner.png

   :alt: Barcode app start screen with scanner.

To begin the adjustment, first scan the *source location*, which is the current location in the
warehouse of the product whose count should be adjusted. Then, scan the product barcode(s).

The barcode of a specific product can be scanned multiple times to increase the quantity of that
product in the adjustment.

.. tip::
   If the warehouse *multi-location* feature is **not** enabled in the database, a source location
   does not need to be scanned. Instead, simply scan the product barcode to start the inventory
   adjustment.

Alternatively, the quantity can be changed by clicking the :guilabel:`✏️ (pencil)` icon on the far
right of the product line.

Doing so opens a separate window with a keypad. Edit the number in the :guilabel:`Quantity` line to
change the quantity. Additionally, the :guilabel:`+1` and :guilabel:`-1` buttons can be clicked to
add or subtract quantity of the product, and the number keys can be used to add quantity, as well.

.. example::
   In the below inventory adjustment, the source location `WH/Stock/Shelf/2` was scanned, assigning
   the location. Then, the barcode for the product `[FURN_7888] Desk Stand with Screen` was scanned
   3 times, increasing the units in the adjustment. Additional products can be added to this
   adjustment by scanning the barcodes for those specific products.

To complete the inventory adjustment, click the green :guilabel:`✅ Apply` button with the check mark
at the bottom of the page.

Once applied, Odoo navigates back to the :guilabel:`Barcode Scanning` screen. A small green banner
appears in the top right corner, confirming validation of the adjustment.

.. admonition:: Did you know?

   Odoo's *Barcode* application provides demo data with barcodes to explore the features of the app.
   These can be used for testing purposes, and can be printed from the home screen of the app.

   To access this demo data, navigate to the :menuselection:`Barcode app` and click :guilabel:`stock
   barcodes sheet` and :guilabel:`commands for Inventory` (bolded and highlighted in blue) in the
   information pop-up window above the scanner.

Manually add products to inventory adjustment
=============================================

When the barcodes for the location or product are not available, Odoo *Barcode* can still be used to
perform inventory adjustments.

To do this, navigate to the :menuselection:`Barcode app --> Barcode Scanning --> Inventory
Adjustments`.

Doing so navigates to the *Barcode Inventory Client Action* page, labeled as :guilabel:`Inventory
Adjustment` in the top header section.

To manually add products to this adjustment, click the white :guilabel:`➕ Add Product` button at the
bottom of the screen.

This navigates to a new, blank page where the desired product, quantity, and source location must be
chosen.

   .. image:: adjustments/adjustments-keypad.png
      :align: center
      :alt: Keypad to add products on Barcode Inventory Client Action page.

First, click the :guilabel:`Product` line, and choose the product whose stock count should be
adjusted. Then, manually enter the quantity of that product, either by changing the `1` in the
:guilabel:`Quantity` line, or by clicking the :guilabel:`+1` and :guilabel:`-1` buttons to add or
subtract quantity of the product. The number pad can be used to add quantity, as well.

Below the number pad is the :guilabel:`location` line, which should read `WH/Stock` by default.
Click this line to reveal a drop-down menu of locations to choose from, and choose the
:guilabel:`source location` for this inventory adjustment.

Once ready, click :guilabel:`Confirm` to confirm the changes.

To apply the inventory adjustment, click the green :guilabel:`✅ Apply` button with the check mark,
at the bottom of the page.

Once applied, Odoo navigates back to the :guilabel:`Barcode Scanning` screen. A small green banner
appears in the top right corner, confirming validation of the adjustment.
