+QRIS QR code on invoices
+========================
+
+`QRIS <https://qris.online/homepage/>`_ is a digital payment system that allows customers to make
+payments by scanning the QR code from their preferred e-wallet.
+
+.. important::
+    According to the `QRIS API documentation <https://qris.online/api-doc/create-invoice.php>`_,
+    QRIS expires after 30 minutes. Due to this restriction, the QR code is not included in reports
+    sent to customers and is only available on the customer portal.
+
+Activate QR codes
+-----------------
+
+Go to :menuselection:`Accounting --> Configuration --> Settings`. Under the :guilabel:`Customer
+Payments` section, activate the :guilabel:`QR Codes` feature.
+
+QRIS bank account configuration
+-------------------------------
+
+Go to :menuselection:`Contacts --> Configuration --> Bank Accounts` and select the bank account for
+which you want to activate QRIS. Set the :guilabel:`QRIS API Key` and :guilabel:`QRIS Merchant ID`
+based on the information provided by QRIS.
+
+.. important::
+   The account holder's country must be set to `Indonesia` on its contact form.
