 Deferred revenues: how to automate them?
 ========================================
+
+Deferred/unearned revenue is an advance payment recorded on the
+recipient's balance sheet as a liability account until either the
+services have been rendered or the products have been delivered.
+Deferred revenue is a liability account because it refers to revenue
+that has not yet been earned, but represents products or services that
+are owed to the customer. As the products or services are delivered over
+time, the revenue is recognized and posted on the income statement.
+
+For example: let's say you sell a 2 year support contract for $24,000
+that begins next month for a period of 24 months. Once you validate the
+customer invoice, the $24.000 should be posted into a deferred revenues
+account. This is because the $24,000 you received has not yet been
+earned.
+
+Over the next 24 months, you will be reducing the deferred revenues
+account by $1,000 ($24,000/24) on a monthly basis and recognizing that
+amount as revenue.
+
+Configuration
+=============
+
+Module installation
+-------------------
+
+In order to automate deferred revenues, go to the settings menu under the application
+:menuselection:`Accounting --> Configuration` and activate the
+**Assets management & revenue recognition** option. This will install the
+**Revenue Recognition Management** module.
+
+.. note::
+
+	In some version of Odoo 9, besides checking this option, you need to install
+	the "Revenue Recognition Management" module. If you are using Odoo 9, you
+	might check if the module is correctly installed.
+
+Define deferred revenue types
+-----------------------------
+
+Once the module is installed, you need to create deferred revenue types.
+From the Accounting application, go to the menu :menuselection:`Configuration --> Deferred
+Revenues Types`.

+
+  Example: 12 months maintenance contract
+
+Some example of deferred revenues types:
+
+-  1 year service contract
+-  3 years service contracts
+
+Set deferred revenues on products
+---------------------------------
+
+Once deferred revenues types are defined, you can set them on the
+related products. On the product form, in the Accounting tab, you can
+set a deferred revenue type.
+
+Here are some examples of products and their related deferred revenue
+types:
+
++---------------------------------+-----------------------------+
+| Product                         | Deferred Revenue Type       |
++=================================+=============================+
+| Support Contract: 3 years       | 3 years service contracts   |
++---------------------------------+-----------------------------+
+| Netflix subscription: 3 years   | 3 years service contracts   |
++---------------------------------+-----------------------------+
+| Flowers every month             | 1 year product contract     |
++---------------------------------+-----------------------------+
+
+Sell and invoice products
+=========================
+
+Once the products are configured, you can create a customer invoice
+using this product. Once the customer invoice is validated, Odoo will
+automatically create a deferred revenue for you, and the related journal
+entry.
+
++----------------------------+----------+----------+
+| **Account**                | **Dr**   | **Cr**   |
++============================+==========+==========+
+| Accounts receivable        | 24000    |          |
++----------------------------+----------+----------+
+| Deferred revenue account   |          | 24000    |
++----------------------------+----------+----------+
+
+Then, every month, Odoo will post a journal entry for the revenue
+recognition.
+
++----------------------------+----------+----------+
+| **Account**                | **Dr**   | **Cr**   |
++============================+==========+==========+
+| Deferred revenue account   | 1000     |          |
++----------------------------+----------+----------+
+| Service revenue account    |          | 1000     |
++----------------------------+----------+----------+
+
+Reporting
+=========
+
+To analyze all your current contracts having a deferred revenue, you can
+use the menu Reporting > Deferred Revenue Analysis.
