+======================
+User default warehouse
+======================
+
+Setting up a **default warehouse** can be useful for field technicians who keep a supply in their
+van or those who always resupply from the same warehouse.
+
+Products in sales orders created during field interventions are always pulled from the same
+warehouse, keeping the inventory accurate with the default warehouse feature.

+
+Configuration
+=============
+
+To set up a user default warehouse, the :doc:`storage locations
+<../../inventory_and_mrp/inventory/management/warehouses/warehouses_locations>` and :ref:`multi-step
+routes <use-routes/routes-rules>` features need to be activated. It is also necessary to have more
+than one warehouse in your database.

+
+User account
+------------
+
+To set up a default warehouse for a specific user, go to :menuselection:`Settings --> Users -->
+Manage users`, open a user, then go to the :guilabel:`Preferences` tab, scroll down to
+:guilabel:`Inventory`, and select the default warehouse from the drop-down menu.

+
+Default warehouse in field service tasks
+========================================
+
+Once a default warehouse has been configured for a user, the materials used for a sales order linked
+to a Field Service task are pulled from that specific warehouse. In the sales order, go to the
+:guilabel:`Other Info` tab, then scroll down to :guilabel:`Delivery`. The default warehouse is
+applied correctly.
