+E-invoicing via mojeRačun
+=========================
+
+Odoo can connect to the national eRačun platform via third-party provider `mojeRačun
+<https://moj-eracun.hr>`_ to send and receive e-invoices.
+
+To make use of this integration, an account and `invoice package
+<https://portal.moj-eracun.hr/podrska/cjenik/>`_ from mojeRačun are needed. The rest of this
+documentation assumes that one has already been obtained.

+Go to :menuselection:`Accounting --> Configuration --> Settings` and scroll down to
+:guilabel:`MojEracun E-invoicing`. Fill the :guilabel:`Username` and :guilabel:`Password` fields
+with the credentials provided by mojeRačun.
+
+Ensure that the :guilabel:`Company ID (OIB or GIN)` and :guilabel:`Company Business Unit (PJ)`
+fields are correctly filled in.
