+==================================
+Sale Order Invoicing Finished Task
+==================================
+
+The requirement of this module is to give the possibility in the task to indicate if a task is available to invoice or not. This means by default even the task is not finished you could set it as invoiceable.
+
+As an option you can relate to a Proyect Stage ( ``project.task.type`` ) this control. For example if you want to assign Invoiceable to stage ``Done`` always
+
+Usage
+=====
+
+To use this module, you need to:
+
+1. Go to Sales -> Product and create a service product
+
+2. In the product go to Invoicing tab and select (1) An invocing policy (2) Track
+   service must be create a task and tack hours (3) Set Invoicing finished task
+   checkbox and save
+
+
+   .. image:: static/description/product_view_invoicefinishedtask.png
+
+
+3. Go to Sales -> Sale orders -> Create a new one. Add a customer y the product
+   you have created
+4. Confirm the sales order, it will create you a proyect and a task
+5. Go to the task and you will find a smartbutton called Not invoiceable, when
+   you press the button you will indicate that the task can be invoiced
+
+   .. image:: static/description/task_view_invoicefinishedtask.png
+
+6. Optional: if you want to use project stages to control this Go To Proyect -> Settings -> Stage -> You have to set true the field Invoiceable in the stages that you consider are invoiceable. Event to use stages for this functionality you can also set it manually in the task whenever you want.
