+===========================
+Deliver Products from Stock
+===========================
+
+Create Storable/Consumable Products
+===================================
+
+The first step to use the inventory application is to create products in
+your database via the menu *Master Data > Products*. Click the Create
+button and enter the name of your product.

+
+In case you set the product as *storable*, you will track the stock
+for this product and know how many units are in stock and what is the
+forecasted number of units. If you want to include a product on
+receipts/deliveries but don’t need to track its stock, you can set it as
+*consumable*.

+Deliver Products from Stock
+===========================
+
+Once you have existing products, you can decide to create a delivery to
+deliver products to your customers. The process in order to do so is
+described in the following print screens.

+
+On the delivery order, you can specify to whom the products will be
+delivered along with the different products and their respective
+quantities. When the delivery is complete you can hit *Validate* and
+the products will go out of your stock.

+
+In case you have a delivery that is planned but shouldn’t be immediately
+validated, you can create a *planned delivery* with a scheduled date
+in the future. You can indicate the initial demand for each product,
+corresponding to what has been ordered by your customer. Once the
+document is filled in, you can hit “Mark as to do” in order to consider
+it in your product forecasts.

+
+Deliver Products from Stock from a Sale Order
+=============================================
+
+If you have the *Sales* application installed, delivery can be
+directly created by *validating a quotation*. You will be able to find
+the corresponding delivery directly on the *sale order*.
