+
+Configuration
+~~~~~~~~~~~~~
+
+To issue electronic documents, ensure your company is configured as explained in the
+:ref:`electronic invoice <l10n_ec/configure-your-company>` section.
+
+In the :abbr:`ATS (Anexo Transaccional Simplificado)`, every document generated in Odoo (invoices,
+vendor bills, sales and purchases withholdings, credit notes, and debit notes) will be included.
+
+Vendor bills
+************
+
+When generating a vendor bill, it is necessary to register the authorization number from the
+invoice that the vendor generated for the purchase. To do so, go to :menuselection:`Accounting
+--> Vendors --> Bills` and select the bill. Then, enter the number from the vendor's invoice in the
+:guilabel:`Authorization Number` field.
+
+Credit and debit notes
+**********************
+
+When generating a credit note or debit note manually or through importation, it is necessary to link
+this note to the sales invoice that is being modified by it.
+
+.. note::
+   Remember to add all required information to the documents before downloading the :abbr:`ATS
+   (Anexo Transaccional Simplificado)` file. For example, add the *Authorization Number* and the
+   *SRI Payment Method* on documents, when needed.
+
+XML generation
+~~~~~~~~~~~~~~
+
+To generate the :abbr:`ATS (Anexo Transaccional Simplificado)` report, go to
+:menuselection:`Accounting --> Reports --> Tax Report` and choose a time period for the desired
+:abbr:`ATS (Anexo Transaccional Simplificado)` report, then click :guilabel:`ATS`.
+
+The downloaded XML file is ready to be uploaded to *DIMM Formularios*.

+.. note::
+   When downloading the :abbr:`ATS (Anexo Transaccional Simplificado)` report, Odoo generates a
+   warning pop-up alerting the user if a document(s) has missing or incorrect data. Nevertheless,
+   the user can still download the XML file.
