+Point of Sale electronic invoicing
+----------------------------------
+
+Make sure the *Ecuadorian module for Point of Sale* (`l10n_ec_edi_pos`) is :ref:`installed
+<l10n_ec/module-installation>` to enable the following features and configurations:
+
+- Choose the SRI payment method in each payment method configuration.
+- Manually input the customer's identification type and identification number when creating a
+  new contact on *POS*.
+- Automatically generate a valid electronic invoice for Ecuador at the end of the checkout process.
+
+Payment method configuration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To :doc:`create a payment method for a point of sale <../../sales/point_of_sale/payment_methods>`,
+go to :menuselection:`Point of Sale --> Configuration --> Payment Methods`. Then, set the
+:guilabel:`SRI Payment Method` in the payment method form.

+
+Identification type and number
+******************************
+
+The POS cashier can :ref:`create a new contact for a customer <pos/customers>` who requests an
+invoice from an open POS session.
+
+The *Ecuadorian Module for Point of Sale* adds two new fields to the contact creation form:
+:guilabel:`Identification Type` and :guilabel:`Tax ID`.
+
+.. note::
+   As the identification number length differs depending on the identification type, Odoo
+   automatically checks the :guilabel:`Tax ID` field upon saving the contact form. To manually
+   ensure the length is correct, know that the :guilabel:`RUC` and :guilabel:`Citizenship` types
+   require 13 and 10 digits, respectively.
+
+Electronic invoice: anonymous end consumer
+******************************************
+
+When clients do not request an electronic invoice for their purchase, Odoo automatically sets the
+customer as :guilabel:`Consumidor Final` and generates an electronic invoice anyway.
+
+.. note::
+   If the client requests a credit note due to a return of this type of purchase, the credit note
+   should be made using the client's real contact information. Credit notes cannot be created to
+   *Consumidor Final* and can be managed :ref:`directly from the POS session <pos/refund>`.
+
+Electronic invoice: specific customer
+*************************************
+
+If a customer requests an invoice for their purchase, it is possible to select or create a contact
+with their fiscal information. This ensures the invoice is generated with accurate customer details.
+
+.. note::
+   If the client requests a credit note due to a return of this type of purchase, the credit note
+   and return process can be managed :ref:`directly from the POS session <pos/refund>`.
