+==========================
+Configure model of entries
+==========================
+
+Overview
+========
+
+In Odoo you have the possibility to pre-fill some accounting entries in
+order to easily reconcile recurrent entries such as bank fees.
+
+We will take the following example to illustrate the concept : Every
+month my company receives a bank fee cost, which depends of our bank
+account current balance. This fee is thus variable.
+
+Create Reconciliation Models
+============================
+
+First, we need to configure two model reconciliation entries. To do so,
+go to the accounting application dashboard. On your bank journal, click
+on :menuselection:`More --> Reconciliation Models`.
+
+.. image:: media/configure01.png
+   :align: center
+
+We want to be able to book our bank fees easily. Our bank deducts fees
+depending on our balance, meaning that it can vary every month.
+
+We create a button Label called Bank fees, select the correct account to
+book those fees. Moreover we also need to specify that the amount type
+is "Percentage of balance" with an Amount of 100%. This parameter will
+tell Odoo to take the entire fee into account.

+
+Save your changes when you are done.
+
+.. note::
+
+	If the amount of your bank fee is fixed, you can as well select **Fixed**
+	under amount type and specify the amount in the amount tap.
+
+.. seealso::
+
+	You can also use this functionality to handle discounts. Please refer to
+	:doc:`../../receivables/customer_invoices/cash_discounts`
+
+Register your payments based on a reconciliation model
+======================================================
+
+Register your payment by importing your bank statements that will be
+impacted by the payment of the bank fee.
+
+When doing the reconciliation, you can select an open balance and click
+the **Reconciliation Model** button (in this case, **Bank Fees**) to get all
+the relevant data instantly.
