+Spanish Chart of Accounts
+=========================
+
+In Odoo, there are several Spanish Chart of Accounts that are available by default:
+
+- PGCE PYMEs 2008
+- PGCE Completo 2008
+- PGCE Entitades 
+
+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 PGCE PYMEs 2008 is installed by default. 
+
+Spanish Accounting Reports
+==========================
+
+If the Spanish Accounting Localization is installed, you will have access to accounting reports specific to Spain:
+
+- Balance Sheet 
+- Tax Report (Modelo 111)
+- Tax Report (Modelo 115)
+- Tax Report (Modelo 303)
