 =============================================
 Use cases in the bank reconciliation process?
 =============================================
+
+Overview
+========
+
+Linking your bank statements with your accounting can be a lot of work.
+You need to find invoices back, relate payments and that amount of
+administration can cast a lot of time. Luckily, with Odoo you can very
+easily link your invoices or any other payment with your bank
+statements.
+
+Two reconciliation processes exist in Odoo.
+
+1. We can directly register a payment on the invoices
+2. We can reconcile open invoices with bank statements
+
+Configuration
+=============
+
+No special configuration is necessary to register invoices. All we need
+to do is install the accounting app.

+User cases
+==========
+
+Case 1: Payments registration
+-----------------------------
+
+We received the payment proof for our invoice of 2100 euros issued to
+Smith & Co.
+
+We start at our issued Invoice of 2100 euros for Smith & Co. Because the
+sold product is a service we demand an immediate payment. Our accountant
+only handles the bank statements at the end of week, so we have to mark
+the invoice as paid so we can remember we can start the service with our
+customer.
+
+Our customer send us a payment confirmation. We can thus register a
+payment and mark the invoice as paid.
+
+.. image:: media/use02.png
+   :align: center
+
+By clicking on **register payment,** we are telling Odoo that our
+customer paid the Invoice. We thus have to specify the amount and the
+payment method
+
+.. image:: media/use03.png
+   :align: center
+
+We can always find the payment back from the Invoice by clicking on the
+:menuselection:`Info --> Open Payment`.
+
+.. image:: media/use04.png
+   :align: center
+
+The invoice has been paid and **the reconciliation has been done
+automatically.**
+
+Case 2: Bank statements reconciliations
+---------------------------------------
+
+We start at our issued Invoice of 3000 euros for Smith & Co. Let's also
+assume that other Invoices are open for different customers.
+
+.. image:: media/use05.png
+   :align: center
+
+We receive our bank statement and not only the invoice of Smith & Co has
+been paid, the one of Buzz of 92 euros as well.
+
+**Import** or **Create** the bank statements. Please refer to the
+documents from the Bank Feeds section.
+

+
+On the dashboard, click on **Reconcile # Items**
+
+.. image:: media/use07.png
+   :align: center
+
+If everything was right (correct partner name, right amount) odoo will
+do the reconciliations **automatically**.
+
+.. image:: media/use08.png
+   :align: center
+
+If some issues are found, you will need to take **manual actions**.
+
+For example, if the partner is missing from your bank statement, just
+fill it in :

+
+If the payment is done with a down payment, just check if it is all
+right and validate all related payments :

+.. tip::
+
+	Hit CTRL-Enter to reconcile all the balanced items in the sheet.
