+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 this is already the case.
+
+.. _croatia/configuration:
+
+Configuration
+-------------
+
+Follow these steps to set up e-invoicing via mojeRačun in Odoo.
+
+.. _croatia/configuration/company:
+
+Company configuration
+~~~~~~~~~~~~~~~~~~~~~
+
+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.
+
+Optionally, specify the :guilabel:`Incoming E-Invoices Journal` where invoices received via MER
+should be created. If unset, the default purchase journal will be used.
+
+Set the :guilabel:`MojEracun Operating Mode` to :guilabel:`Production` to send and receive invoices
+on the production network.
+
+Then click :guilabel:`Activate` to activate the connection with mojeRačun.
+
+.. _croatia/configuration/journal:
+
+Journal configuration
+~~~~~~~~~~~~~~~~~~~~~
+
+Go to :menuselection:`Accounting --> Configuration --> Journal` and click the :guilabel:`Customer
+Invoices` journal to open its configuration.
+
+In the :guilabel:`Fiscalization (HR)` section, fill the :guilabel:`Business premises label`,
+:guilabel:`Issuing device label`, :guilabel:`Business premises label (refund approval)`, and
+:guilabel:`Issuing device label (refund approval)` fields.
+
+These fields are used to generate the :ref:`invoice name <croatia/sending/invoice-name>` in
+accordance with the Croatian standard. The :guilabel:`refund approval` fields are used for credit
+notes.
+
+.. _croatia/sending:
+
+Sending an e-invoice
+--------------------
+
+When creating an invoice, the following configuration is needed to correctly send the invoice
+via mojeRačun.
+
+.. _croatia/sending/invoice-name:
+
+Invoice name
+~~~~~~~~~~~~
+
+The invoice name must be in the form `{Journal code}-{Year}-{Sequence}/{Business premises label}/
+{Issuing device label}`. This format is suggested by default when creating the first invoice in
+a Sales journal where the :ref:`journal configuration <croatia/configuration/journal>` was performed
+as explained above.
+
+If invoices in an existing journal must be sent via mojeRačun, the invoices of that journal must be
+resequenced to follow the correct format.
+
+Product configuration
+~~~~~~~~~~~~~~~~~~~~~
+
+The :guilabel:`KPD category` must be set on the product.
+
+Fetching status updates
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Once an invoice has been sent, Odoo will periodically check for any updates to the invoice's status
+(e.g. rejection by MER, the eRačun system, or by the recipient). To manually check for updates,
+click the :guilabel:`MER: Fetch status` button.
+
+Reporting a payment
+~~~~~~~~~~~~~~~~~~~
+
+The Croatian government expects to be notified once payment has been received for an invoice. To
+send this notification, click the :guilabel:`MER: Report payments` button.
+
+.. _croatia/receiving:
+
+Receiving e-invoices
+--------------------
+
+Odoo periodically checks for new invoices received via mojeRačun. New invoices received via
+mojeRačun appear in the :guilabel:`Incoming E-Invoices Journal` specified in the
+:ref:`croatia/configuration/company <settings>`.
+
+Rejecting an invoice
+~~~~~~~~~~~~~~~~~~~~
+
+To reject an incoming invoice, click the :guilabel:`MER: Reject eRacun` button. This notifies the
+eRačun system and the sender that the invoice is not accepted.
