+In "Point of Sale" configuration "Product Quantity" section activate "Display Product Quantity" feature:

+
+By default quantity is displayed for the warehouse that is used in the POS stock operation type.
+
+You can add additional warehouses to show quantity in by adding them into "Additional Warehouses" field.
+
+In this case the following information will be displayed on product tiles:
+
+- Total quantity = quantity in the default warehouse + quantity in the additional warehouses
+
+- Quantity in the default warehouse
+
+- Quantity in the additional warehouses.

+This module allows to display product quantities in selected locations in real time. Quantities are displayed directly on product tiles:
+  .. image:: ../static/img/pos_quantity.png
+
+Once a product quantity is changed it will be simultaneously updated in all active POS.
+
+This module depends on stock_available module which is available in https://github.com/OCA/stock-logistics-availability repo.

+This module requires connection to update quantities and doesn't support offline mode.
+Warehouses must belong to the same company as POS.
