+PromptPay QR code on invoices
+=============================
+
+The **PromptPay QR code** is a QR code that can be added to invoices to allow customers to pay their
+bills using the PromptPay-supported bank mobile application. The QR code is generated based on the
+**invoice amount** and one of the following **merchant information**:
+
+- Ewallet ID
+- Merchant Tax ID
+- Mobile Number
+
+Activate QR codes
+-----------------
+
+Go to :menuselection:`Accounting --> Configuration --> Settings`. Under the :guilabel:`Customer
+Payments` section, activate the :guilabel:`QR Codes` feature.
+
+PromptPay QR bank account configuration
+---------------------------------------
+
+Go to :menuselection:`Contacts --> Configuration --> Bank Accounts` and select the bank account for
+which you want to activate PromptPay QR. Set the :guilabel:`Proxy Type` and fill in the
+:guilabel:`Proxy Value` field depending on the chosen type.
+
+.. important::
+   - The :guilabel:`Include Reference` checkbox doesn't work for PromptPay QR codes.
