+Bacs files
+==========
+
+:abbr:`Bacs (Bankers' Automated Clearing Services)` files are electronic files used in the UK to
+process payments and transfers between bank accounts.
+
+To enable the use of Bacs files, make sure the :ref:`UK BACS Payment Files <united-kingdom/modules>`
+module is installed, then:
+
+#. Configure your Bacs Service User Number:
+
+   #. Go to :menuselection:`Accounting --> Configuration --> Settings` and scroll down to the
+      :guilabel:`Customer Payments` section.
+   #. Enter your :guilabel:`Service User Number` under :guilabel:`BACS` and manually save.
+
+#. Configure your **bank** journal:
+
+   #. Go to :menuselection:`Accounting --> Configuration --> Journals` and select your **bank**
+      journal.
+   #. In the :guilabel:`Journal Entries` tab, configure the :guilabel:`Account Number` and
+      :guilabel:`Bank` fields.
+   #. In the :guilabel:`Incoming Payments` and :guilabel:`Outgoing Payments` tabs, make sure the
+      :guilabel:`BACS Direct Debit` payment method is enabled.
+
+#. Configure the contacts for whom you wish to use Bacs files: Access the contact form and, in
+   the :guilabel:`Accounting` tab, click :guilabel:`Add a line` and fill in the
+   :guilabel:`Account Number` and :guilabel:`Bank` fields.
+
+Bill payments
+-------------
+
+To generate Bacs files for bill payments, set the :guilabel:`Payment Method` to
+:guilabel:`BACS Direct Debit` when :ref:`registering vendor payments <batch-payments/register-payments>`.
+
+Then, create a vendor batch payment:
+
+#. Go to :menuselection:`Accounting --> Vendors --> Batch Payments`, and click :guilabel:`New`.
+#. Select the bank journal in the :guilabel:`Bank` field, set the :guilabel:`Payment Method` to
+   :guilabel:`BACS Direct Credit`, and select a :guilabel:`BACS Processing Date`.
+#. Optionally, you can also:
+
+   - select a :guilabel:`BACS Expiry Date`;
+   - enable :guilabel:`BACS Multi Mode` to process the payments on their individual date.
+
+#. Click :guilabel:`Add a line`, select the payments you want to include, click :guilabel:`Select`,
+   then :guilabel:`Validate`.
+
+Once validated, the Bacs file is available in the chatter. You can also :guilabel:`Re-generate
+Export File` if you need a new Bacs file for that batch payment.

+
+Invoice payments
+----------------
+
+Before generating Bacs files for invoice payments, you must first create a **BACS Direct Debit
+Instruction**: Go to :menuselection:`Accounting --> Customers --> BACS Direct Debit Instructions`
+and click :guilabel:`New`. Select a :guilabel:`Customer`, their :guilabel:`IBAN`, and the
+:guilabel:`Journal` you wish to use.
+
+To generate Bacs files for invoice payments, set the :guilabel:`Payment Method` to
+:guilabel:`BACS Direct Debit` when :ref:`registering invoice payments <batch-payments/register-payments>`.
+
+.. tip::
+   If you register the payment for an invoice linked to a subscription or via
+   :menuselection:`Accounting --> Customers --> Payments`, you can select the :guilabel:`BACS
+   Payment Type`:
+
+   - :guilabel:`Direct debit-first collection of a series`;
+   - :guilabel:`Direct debit single collection`;
+   - :guilabel:`Direct debit repeating collection in a series`;
+   - :guilabel:`Direct debit-final collection of a series`.
+
+Then, create a customer batch payment:
+
+#. Go to :menuselection:`Accounting --> Customers --> Batch Payments`, and click :guilabel:`New`.
+#. Select the bank journal in the :guilabel:`Bank` field, set the :guilabel:`Payment Method` to
+   :guilabel:`BACS Direct Credit`, and select a :guilabel:`BACS Processing Date`.
+#. Optionally, you can also:
+
+   - select a :guilabel:`BACS Expiry Date`;
+   - enable :guilabel:`BACS Multi Mode` to process the payments on their individual date.
+
+#. Click :guilabel:`Add a line`, select the payments you want to include, click :guilabel:`Select`,
+   then :guilabel:`Validate`.
+
+Once validated, the Bacs file is available in the chatter. You can also :guilabel:`Re-generate
+Export File` if you need a new Bacs file for that batch payment.
