-This modules helps to get Invoicing Policy on Sale Order Level without
-breaking behaviour (as it is defined from >= v10 on product level).
+This module adds an invoicing policy on sale order level in order to
+apply that invoicing policy on the whole sale order.
+
+That invoicing policy can take three values:
+
+- Products Invoicing Policy: The sale order will follow the standard
+  behavior and apply the policy depending on products configurations.
+- Ordered Quantities: The sale order will invoice the ordered quantities.
+- Delivered Quantities: The sale order will invoice the delivered quantities.
+
+Following the chosen policy, the quantity to invoice and the
+amount to invoice on each line will be computed accordingly.
+
+You will be able also to define a default invoicing policy
+(globally per company)
+that can be different than the default invoicing policy for new products.

+Use Cases / Context
+===================
+
+In Odoo, products have their own invoicing policy that can be:
+
+- Invoicing on ordered quantities
+- Invoicing on ordered quantities
+
+Following that configuration, when trying to create invoices from
+sale orders, each line of product will apply its invoicing policy.
+
+In some cases, user needs to apply an invoicing policy on a whole
+sale order.
+
+The solution proposed here is to add an invoicing policy on
+sale order level.
+
+Configuration
+=============
+
+* Go to Sale > Configuration > Settings > Sale Invoice Policy
+* Choose the one that fits your needs.
+
 Usage
 =====
 
 * Create Sale Order
-* Select Invoicing Policy on Sale Order or let it void
-* Either the policy selected on Sale Order would be used, either if not
-  filled in, the policy would be chosen from product configuration
+* Select Invoicing Policy on Sale Order or let it on Products Invoicing Policy
+* The created invoices will use the configuration on sale order.
