+How to manage batch deposits of checks?
+=======================================
+
+When your company's collections group receives checks from customers
+they will often place this money into their bank account in batches. As
+this money has been received in a physical form, someone in your company
+must manually bring the checks to the bank.
+
+The bank will ask for a deposit ticket (also referred to as deposit
+slip) to be filled-in with the details of the checks or cash to be
+included in the transactions.
+
+The bank statement will reflect the total amount that was deposited and
+the reference to the deposit ticket, not the individual checks.
+
+Odoo assists you to prepare and print your deposit tickets, and later on
+reconcile them with your bank statement easily.
+
+Configuration
+=============
+
+Install the batch deposit feature
+---------------------------------
+
+In order to use the batch deposit feature, you need the module **Batch
+Deposit** to be installed.
+
+.. note::
+
+    Usually, this module is automatically
+    installed if checks are widely used in your country.
+
+To verify that the **Batch Deposit** feature is installed, go to the
+:menuselection:`Configuration --> Settings` menu of the accounting application.
+Check the feature: **Allow batch deposit**.

+
+Activate the feature on your bank accounts
+------------------------------------------
+
+Once you have installed this feature, Odoo automatically activate bank
+deposits on your main bank accounts.
+
+To control which bank account can do batch deposit and which can not, go
+to the journal that you defined to pay your checks, usually called
+'Checks' or 'Bank' (see :doc:`../../receivables/customer_payments/check`,
+in the Accounting apps, :menuselection:`Configuration --> Accounting --> Journals`.
+
+In **Advanced Settings** tab, in section **Miscellaneous**, set Debit Method to
+**Batch Deposit**.
+
+.. image:: media/batch02.png
+   :align: center
+
+If you check **Batch Deposit** in your debit method field, it means that
+payments created using this Journal (called Payment method when you want
+to make or receive a payment) will be applicable for the creation of
+Batch Deposits afterwards.
+
+From checks received to the bank
+================================
+
+Receive customer checks
+-----------------------
+
+Once your record checks received, record them on the bank account on
+which you plan to deposit them. Once you select the bank account (or
+check journal is you configured Odoo that way), Odoo proposes you to use
+a batch deposit. Select this option if you plan to deposit the check to
+your bank.
+
+.. image:: media/batch03.png

+
+In the memo field, you can set the reference of the check.
+
+.. note::
+
+    payments can be registered from the menu :menuselection:`Sales --> Payments`,
+    or directly on the related invoice, using the **Register Payment** button.
+
+Prepare a batch deposit
+-----------------------
+
+From the Accounting application, go to the menu :menuselection:`Sales --> Batch Deposit`,
+and create a new **Batch Deposit**.
+
+.. image:: media/batch04.png
+   :align: center
+
+Select the bank, then select the payments (checks) you want to add in
+this deposit. By default, Odoo proposes you all the checks that have not
+been deposit yet. That way, you can verify that you do not forget or
+lost a check.
+
+.. image:: media/batch05.png
+   :align: center
+
+You can then print the batch deposit, which will be very useful
+to prepare the deposit slip that the bank usually requires to complete.
+
+Reconciling the Deposit with the Bank Statement
+-----------------------------------------------
+
+When you process the bank statement reconciliation you will see the
+deposit ticket number referenced in the statement. When the reconciliation
+process is run, the user will be able to select the batch deposit that
+matches with the bank statement line.
+
+.. image:: media/batch06.png
+   :align: center
+
+If you select a batch deposit, Odoo will automatically fills all the
+checks contained in this deposit for the matching. (2 checks were in
+this batch deposit the example below)

+
+Troubleshooting
+===============
+
+I don't see the batch deposit link on bank statements?
+------------------------------------------------------
+
+If you don't have a batch deposit link in your bank statement, there
+could be two reasons:
+
+- After having installed the batch deposit features, you need to reload
+  the page so that the browser is aware of this new feature. Just
+  click the reload button of your browser.
+
+- You do not have a batch deposit created for this bank account.
+
+What happens if a check was refused?
+------------------------------------
+
+If you have a smaller amount in your bank statement than the actual
+amount in your batch deposit, it probably means that one of your check
+has been refused.
+
+In this case, click on the line related to this check to remove it from
+the bank statement matching.
