+================
+Customer account
+================
+
+The **Customer account** feature allows customers to use their account to make purchases. On the one
+hand, they can deposit money for future purchases or, on the other hand, select their account as
+:doc:`payment method <../payment_methods>` to purchase items on credit and :ref:`settle the debt
+later <pos/settle_debt>` through a point-of-sale transaction or via an issued invoice.
+
+.. _pos/payment_method/configuration:
+
+Configuration
+=============
+
+To allow customers to pay using their customer account, :doc:`create a payment method
+<../payment_methods>` and configure it as follows:
+
+#. Tick the :guilabel:`Identify Customer` checkbox.
+#. Keep the :guilabel:`Journal` field blank to use the customer's receivable account.
+#. Once configured, navigate to the :ref:`POS settings <configuration/settings>`.
+#. Add the payment method to the :guilabel:`Payment Methods` field.
+
+.. note::
+   - Set a maximum sales credit to prevent customers from exceeding a defined credit limit. Once the
+     maximum credit amount is reached, the selected customer button turns orange and a
+     :icon:`fa-warning` (:guilabel:`warning sign`) icon appears next to the customer’s name as a
+     warning. However, this warning does **not** prevent a sale from proceeding.
+   - A payment method for the customer account, named :guilabel:`Customer Account` is created and
+     configured by default when creating a point of sale.

+
+Payment process
+===============
+
+Deposit money
+-------------
+
+To deposit money to the customer account from the POS interface:
+
+#. Click :guilabel:`Customer` to open the list of customers.
+#. Locate the desired customer and click the :icon:`fa-bars` (:guilabel:`hamburger menu`) icon to
+   open the dropdown menu.
+#. Click :guilabel:`Deposit money`.
+#. Choose the payment method.
+#. When redirected to the payment screen, enter the amount to deposit using the keypad.
+#. :guilabel:`Validate` the transaction.
+#. Click :guilabel:`Yes` on the popup window to confirm.
+
+Pay using the customer account
+------------------------------
+
+To use the customer account to pay for a purchase from the POS payment screen:
+
+#. Select the payment method :ref:`created for the customer account
+   <pos/payment_method/configuration>`.
+#. Click :icon:`fa-user` :guilabel:`Customer` to open the customer list and select a customer.
+#. Tick the :guilabel:`Invoice` button.
+#. :guilabel:`Validate` the purchase.
+
+.. important::
+   To effectively monitor and manage the customer’s unpaid debt, either :doc:`create an invoice
+   <../receipts_invoices>` for the order or activate the :doc:`Accounting application
+   <../../../finance/accounting>`.
+
+To ensure due balance follow-up, generate an invoice or download the accounting application.
+
+Debt tracking
+=============
+
+When a customer pays using their customer account, they make purchases on credit; meaning the
+purchase amount is considered a debt until the customer pays it off. To keep track of a customer’s
+debt, consult their customer statement in the backend or their profile in an open session.
+
+To access the :guilabel:`Customer Statement` report, go to :menuselection:`Point of Sale --> Orders
+--> Customers`, select a customer to open their form, and click the :guilabel:`Customer Statements`
+smart button.
+
+To overview the total amount due or deposited by a customer from an open session, access the
+customer list by clicking :guilabel:`Customer` and search for the desired customer; the amount due
+or deposited is displayed next to their name.

+   When a customer is related to a company, the customer statement report might be related to the
+   company itself, and not the customer.
+
+.. _pos/settle_debt:
+
+Due amount settlement
+=====================
