+==============================================
+
+Minimum Stock rules and Make to Order have similar consequences but
+different rules. They should be used depending on your manufacturing and
+delivery strategies.
+
+Terminology
+===========
+
+Minimum stock rule 
+-------------------
+
+Minimum Stock rules are used to ensure that you always have the minimum
+amount of a product in stock in order to manufacture your products
+and/or answer to your customer needs. When the stock level of a product
+reaches its minimum the system will automatically generate a procurement
+order with the quantity needed to reach the maximum stock level.
+
+Make to Order
+-------------
+
+The Make to Order function will trigger a Purchase Order of the amount
+of the Sales Order related to the product. The system will **not** check
+the current stock. This means that a draft purchase order will be
+generated regardless of the quantity on hand of the product.
+
+Configuration
+=============
+
+Minimum stock rules
+-------------------
+
+The Minimum Stock Rules configuration is available through your
+Inventory module. In the Inventory Control menu select "Reordering Rule"
+in the drop down menu. There, click on "Create" to set minimum and
+maximum stock values for a given product.

+    Show tooltips for "minimum quantity", "maximum quantity" and "quantity multiple"
+    fields
+
+Then, click on your product to access the related product form and, on
+the "Inventory submenu", do not forget to select a supplier.

+
+.. tip::
+    Don't forget to select the right product type. A consumable
+    can not be stocked and will thus not be accounted for in the stock valuation.
+
+Make to Order 
+--------------
+
+The Make to Order configuration is available on your product form
+through your :menuselection:`Inventory --> Inventory control --> Products` (or any
+other module where products are available).
+
+On the product form, under Inventory, click on "Make To Order".

+
+Choice between the two options
+------------------------------
+
+The choice between the two options is thus dependent of your inventory
+strategy. If you prefer to have a buffer and always have at least a
+minimum amount, the minimum stock rule should be used. If you want to
+reorder your stocks only if your sale is confirmed it is better to use
+the Make to Order.
