[IMP] accounting: send and print workflow in electronic_invoicing

From saas-16.2, the choice of the format can be made from the partner
form view (for the formats present in `account_edi_ubl_cii` only). And
the attachment are generated during the Send & Print flow.

 Configuration
 =============
 
-Go to :menuselection:`Accounting --> Configuration --> Journals --> Customer Invoices --> Advanced
-Settings --> Electronic Invoicing` and enable the formats you need for this journal.
+By default, the format available in the :ref:`send window <e-invoicing/generation>` depends on your
+customer's country.
 
-.. image:: electronic_invoicing/formats.png
-   :align: center
-   :alt: Select the EDI format you need
+You can define a specific e-invoicing format for each customer. To do so, go to
+:menuselection:`Accounting --> Customers --> Customers`, open the customer form, go to the
+:guilabel:`Accounting` tab and select the appropriate format.
 
-Once an electronic invoicing format is enabled, XML documents are generated when clicking on
-:guilabel:`Confirm` in documents such as invoices, credit notes, etc. These documents are either
-visible in the attachment section, or embedded in the PDF.

+   :alt: Select an EDI format for a specific customer
 
-.. note::
-   - For E-FFF, the xml file only appears after having generated the PDF (:guilabel:`Print` or
-     :guilabel:`Send & Print` button), since the PDF needs to be embedded inside the xml.
-   - Every PDF generated from Odoo contains a :guilabel:`Factur-X` XML file (for interoperability purpose).
-     For German and French companies, the option :guilabel:`Factur-X (PDF/A-3)` in addition enables
-     validation checks on the invoice and generates a PDF/A-3 compliant file, required by plaftorms like Chorus Pro.
-   - The formats available depend on the country registered in your company's :guilabel:`General
-     Information`.
-   - Odoo supports the **Peppol BIS Billing 3.0** format that can be used via existing access
-     points.
+Peppol formats
+--------------
+
+Use the fields :guilabel:`Peppol e-address (EAS)` and :guilabel:`Peppol Endpoint` to identify the
+recipient in the Peppol Network.

+National electronic invoicing
+-----------------------------
+
+Depending on your company's country (e.g., :doc:`Italy <../../../fiscal_localizations/italy>`,
+:doc:`Spain <../../../fiscal_localizations/spain>`, :doc:`Mexico
+<../../../fiscal_localizations/mexico>`, etc.), you may be required to issue e-invoicing documents in
+a specific format for all your invoices. In this case, you can define a default e-invoicing format
+for your sales journal.
+
+To do so, go to :menuselection:`Accounting --> Configuration --> Journals`, open your sales journal,
+go to the :guilabel:`Advanced Settings` tab, and enable the formats you need for this journal.
