+Perform inventory adjustments and stock counts directly from the Barcode
+scanner app.
+
+The operator picks an internal location, scans the products found there
+(with ``barcode_gs1`` installed, a GS1 label also brings its lot/serial
+and quantity), types the counted quantity, and applies. Each adjustment
+is recorded as a
+`stock_inventory <https://github.com/OCA/stock-logistics-warehouse>`__
+adjustment group — draft → in progress → done — so every barcode count
+leaves a traceable, auditable record with its own move lines, using
+Odoo's native on-hand adjustment mechanism (``stock.quant``).
+
+This is a feature module on top of ``barcode_scanner``: it registers its
+own screens, scan handling and home-screen tile into the scanner core
+without patching it, so you install only what you need.

+
+Usage
+=====
+
+From the Barcode app home screen, tap **Inventory Adjustment**.
+
+Count a location
+----------------
+
+1. **Pick or scan the location** to count. Scanning a location barcode
+   jumps straight into the count; otherwise choose one from the
+   searchable list of internal locations.
+2. The count screen shows the stock the location holds, one line per
+   product and lot. **Count by scanning** each product: a plain barcode
+   adds one unit. With ``barcode_gs1`` installed, a GS1 label also
+   brings its **lot/serial** and its **quantity**; without it, the
+   scanner reads plain EAN-13 barcodes only. You can also type the
+   counted quantity in each line, decimals included, which then shows
+   how far it is from the stock.
+3. To count something not shown, tap **"+"** and scan or search the
+   product. A freshly scanned or added product jumps to the top of the
+   list and is highlighted, so you always see what the scan just
+   changed. Only storable products can be counted: services and
+   non-storable consumables are not offered, and scanning one says why
+   it is refused.
+4. Tap **Apply Adjustment** to record the count. If the stock of a
+   counted product changed while you counted — goods came in or went out
+   — nothing is applied yet: the lines show the stock as it is now, and
+   you choose whether to apply your count anyway or to count again.
+
+Lots and serial numbers
+-----------------------
+
+A lot/serial-tracked product needs its lot/serial before it can be
+applied — read from a GS1 label, or typed into the line (the lots a
+count at that location can use are suggested; a new name is created on
+the server). The name is matched exactly first, as lots differing only
+in case are different lots; in another case it is only taken when it
+names a single lot. The same product can appear on **several lines**,
+one per lot or serial number, so it stays available in the **"+"**
+picker even after it already has a line.
+
+A serial number counts one unit: reading it again warns instead of
+counting it twice.
+
+What it records
+---------------
+
+Each adjustment is applied as a
+`stock_inventory <https://github.com/OCA/stock-logistics-warehouse>`__
+adjustment group (draft → in progress → done), scoped to exactly the
+counted products at the counted location, using Odoo's native on-hand
+adjustment. Every barcode count therefore leaves one traceable,
+auditable record with its own move lines. Lots are created in the
+counted location's company.
+
+A count covers the stock at the location itself, outside packages and
+not owned by a partner: its sublocations are counted on their own, and
+stock in a package or owned by someone else is neither shown nor
+changed.
+
+As in the back office, applying a count requires **Inventory
+Administrator** rights. Other users are told so when they open
+**Inventory Adjustment**.
