+Egyptian e-invoicing
+====================
+
+Odoo is compliant with the **Egyptian Tax Authority (ETA) e-invoicing** requirements.

+   </administration/upgrade>` your database.

+
+.. _egypt/e-invoicing-eta-portal:
+
+Register Odoo on your ETA portal
+--------------------------------
+
+You must register your Odoo ERP system on your ETA portal to get your API credentials. You need
+these codes to :ref:`configure your Odoo Accounting app <egypt/e-invoicing-configuration>`.
+
+Access your company profile on the ETA portal by clicking on :guilabel:`View Taxpayer Profile`.

+
+Once successfully registered, the website displays your API credentials:

+- Client ID
+- Client Secret 1
+- Client Secret 2
+
+.. note::
+   - ETA should give you a username and a password to access their online portal.
+   - Ask ETA to provide you with preproduction portal access as well.
+   - These codes are confidential and should be stored safely.
+
+.. _egypt/e-invoicing-configuration:
+
+Configuration on Odoo
+---------------------
+
+To connect your Odoo database to your ETA portal account, go to :menuselection:`Accounting -->
+Configuration --> Settings --> ETA E-Invoicing Settings`, and set the :guilabel:`ETA Client ID` and
+:guilabel:`ETA Secret` that you retrieved when you :ref:`registered Odoo on your ETA portal
+<egypt/e-invoicing-eta-portal>`. Set an invoicing threshold if needed.

+
+.. important::
+   - **Test on your preproduction portal** before starting to issue real invoices on the production
+     ETA portal.
+   - **Credentials** for preproduction and production environments are different. Make sure to
+     update them on Odoo when you move from one environment to another.
+   - If not done yet, fill out your company details with your company's full address, country, and
+     Tax ID.
+
+.. _egypt/e-invoicing-eta-codes:
+
+ETA codes
+~~~~~~~~~
+
+E-invoicing works with a set of codes provided by the ETA. You can use the `ETA documentation
+<https://sdk.preprod.invoicing.eta.gov.eg/codes/>`_ to code your business attributes.
+
+Most of these codes are handled automatically by Odoo, provided that your :ref:`branches
+<egypt/e-invoicing-branches>`, :ref:`customers <egypt/e-invoicing-customers>`, and :ref:`products
+<egypt/e-invoicing-products>` are correctly configured.
+
+- Company Information:
+
+  - Company Tax ID
+  - | Branch ID
+    | If you have only one branch, use ``0`` as the branch code.
+  - Activity type Code
+
+- Other Information:
+
+  - | Product Codes
+    | Your company's products should be coded and matched with their **GS1** or **EGS** codes.
+  - | Tax Codes
+    | Most of the taxes codes are already configured on Odoo in the :guilabel:`ETA Code (Egypt)`
+      field. We advise you to make sure these codes match your company's taxes.
+
+.. seealso::
+   - `Egyptian eInvoicing & eReceipt SDK - Code Tables

+
+.. _egypt/e-invoicing-branches:
+
+Branches
+~~~~~~~~
+

+:guilabel:`Create`.
+
+Name the journal according to your company's branch and set the :guilabel:`Type` as
+:guilabel:`Sales`. Next, open the :menuselection:`Advanced Settings` tab and fill out the

+
+.. note::
+   You can contact the :abbr:`ETA (Egyptian Tax Authority)` or `Egypt Trust
+   <https://www.egypttrust.com/>`_ to get these USB keys.
