+German Chart of Accounts
+========================
+
+The chart of accounts SKR03 and SKR04 are both supported in Odoo. You can choose the
+one you want by going in :menuselection:`Accounting --> Configuration` then choose the
+package you want in the Fiscal Localization section.
+
+Be careful, you can only change the accounting package as long as you have not created any accounting entry. 
+
+.. tip::
+
+    When you create a new SaaS database, the SKR03 is installed by default. 
+
+German Accounting Reports
+=========================
+
+Here is the list of German-specific reports available on Odoo Enterprise:
+
+- Balance Sheet 
+- Profit & Loss
+- Tax Report (Umsatzsteuervoranmeldung)
+- Partner VAT Intra
+

+feature, the german accounting localization needs to be installed on your Odoo Enterprise database.
