+================
+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_accounts>` 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.

+
+Debt tracking
+=============
+
+Tracking a customer due amount differs depending on the pos config
+
+Option 1: only pos is installed
+Mandatory: generate an invoice
+how to track:
+customer, custo statement,
+
+what happens if no invoice generated:
+Not part of the customer statement,
+when click on POS order smart button: the order is considered paid but to invoice.
+
+Accounting installed:
+Customer accounting always available as long as there's
+
+
+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 by a customer from an open session, access the customer list by
+clicking :guilabel:`Customer` and search for the desired customer; the amount due is displayed next
+to their name.
+
+.. seealso::
+   :doc:`../../../finance/accounting/payments/follow_up`
+
+.. note::
+   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_accounts:
+
+Due account settlement
+======================
+
+To settle a customer's due amount, :ref:`register the payment from the invoice

+#. Click :guilabel:`Customer` and search for the desired customer in the list.
