+===================
+Cash reconciliation
+===================
+
+By default in Odoo, payments registered in the **cash journal** are automatically reconciled with an
+**outstanding account** and their related invoices or bills marked as *In Payment* until they are
+reconciled with a bank statement. It is possible to :ref:`bypass <cash-reconciliation-bypass>` the
+*In Payment* status for cash transactions, therefore removing the need to reconcile with a bank
+statement.

+
+Cash logs
+=========
+
+At the start of each day, create a **cash log**. To do so, go to your :guilabel:`Accounting
+Dashboard` and click :guilabel:`New Transaction` in the :guilabel:`Cash` journal.
+
+.. image:: cash_transactions/new-transaction.png
+   :align: center
+   :alt: Create a new cash log.
+
+Enter the :guilabel:`Starting Balance` of your cash float and save, but do *not* post the entry yet.
+Create your invoice by going to :menuselection:`Accounting dashboard --> Customers --> Invoices` and
+confirm it. Click :guilabel:`Register Payment` and select the cash :guilabel:`Journal`. Repeat the
+process for each invoice.
+
+.. image:: cash_transactions/cash-payment-journal.png
+   :align: center
+   :alt: Select Cash journal upon payment registration.
+
+Go back to your :guilabel:`Accounting Dashboard`, and click again on :guilabel:`New transactions`.
+Click on the :guilabel:`Add a line` button in the :guilabel:`Transactions` tab, and enter the total
+of cash earned during the day. Add a label name according to your needs. Input the amount displayed
+under :guilabel:`Computed Balance` in the :guilabel:`Ending Balance` field, and make sure it matches
+your end cash float.
+
+Once certain the **computed balance** is correct, click :guilabel:`Save`, :guilabel:`Post`, and
+then :guilabel:`Reconcile`. This will take you to the **bank reconciliation** page.
+
+Cash payments reconciliation
+============================
+
+On the **bank reconciliation** page, search through the list for the **cash log** transaction you
+created earlier. To be able to match all cash payments, make sure no **partner** is selected in the
+:guilabel:`Select Partner` field. If a **partner** is selected, click in the field and delete the
+partner. Then, pair (or match) each cash payment with your cash log by clicking on the payment in
+the :guilabel:`Customer/Vendor Matching`, and :guilabel:`validate`.
+
+.. image:: cash_transactions/cash-payment-reconciliation.png
+   :align: center
+   :alt: Cash payments reconciliation.
+
+.. note::
+   If your ending cash balance is **over** or **under** the computed balance, add another
+   :guilabel:`Transaction` line corresponding to the **over** or **under** amount in order to match
+   it later during reconciliation.
+
+Cash reconciliation bypass
+==========================
+
+.. _cash-reconciliation-bypass:
+
+.. important::
+   Bypassing the cash journal is recommended **only for organizations** that do not need a
+   cash report or do not wish to reconcile cash.
+
+To bypass the *In Payment* status, go to :menuselection:`Accounting app --> Configuration -->
+Accounting: Journals` and select the :guilabel:`Cash` journal. Click on the :guilabel:`Payments
+Configuration` tab and set a `Cash` account in both the :guilabel:`Outstanding Receipts Account` and
+:guilabel:`Outstanding Payments Account` fields, then save. Payments registered in the **cash**
+journal now bypass the *In Payment* status.
+
+.. image:: cash_transactions/cash-payments-config.png
+   :align: center
+   :alt: Configuration tab of the cash journal.
+
+.. tip::
+   In case you use cash to pay expenses, advance employees, are required to keep records of cash
+   flows, or use anything resembling a cash box, you can benefit from creating a second **cash
+   journal** that *does* use the **outstanding accounts**. This way, you can both generate *and*
+   reconcile bank statements when closing your POS session or your books at the end of the day.
