+Reports
+=======
+
+GST report
+----------
+
+The **Goods and Services Tax (GST) report** is a critical tax reporting requirement for businesses
+registered for GST in New Zealand. The GST Return is used to report and remit GST to the
+**Inland Revenue Department (IRD)**.
+
+.. image:: new_zealand/GST_report.png
+   :alt: GST Report.
+
+The base and tax amounts are collected from the **GST**, which is pre-configured in Odoo to align
+with New Zealand's GST Return requirements (Boxes 1-15). The **GST** can also be manually
+configured for special use cases, such as specific GST treatments (e.g., zero-rating for exported
+agricultural goods). Once the **GST** setup for each account is complete, Odoo automatically
+categorises journal items into the appropriate boxes. This ensures the **GST** Return is
+accurate and fully reflects the business's financial activities.
+
+.. image:: new_zealand/GST_report_journal_items.png
+   :alt: GST Reprot Journal items.
+
+Closing the GST report
+~~~~~~~~~~~~~~~~~~~~~~
+
+When it is time to file the tax return with the **IRD**, click Closing entry. The tax return
+period can be configured in :menuselection:`Configuration --> Settings --> Tax Return Periodicity`.
+The start date of the tax return period can also be defined on the report itself through the
+**period button** (marked by a calendar icon :icon:`fa-calendar`).
+
+.. seealso::
+   - :doc:`../../../applications/finance/accounting/reporting/year_end`
+
+Before closing the entry for the first time, the default **GST Payable Account** and **GST
+Receivable Account** need to be set. A notification will prompt the user to configure the tax
+groups.
+
+ .. image:: new_zealand/GST_report_tax_groups.png
+   :alt: GST Reprot Tax Goups.
+
+ Once the **GST Payable** and **GST Receivable** accounts are set up, the **Tax Return** report
+ generates an accurate journal closing entry automatically, balancing the GST balance with the GST
+ clearing account.
+
+ The balance between **GST Receivable** and **Payable** is set against the tax clearing account
+ defined on the tax group. The amount to be paid to or received from **IRD** can then be reconciled
+ with a bank statement.
+
+  .. image:: new_zealand/GST_report_tax_journal_items.png
+   :alt: GST Reprot Tax Journal Items.
+
+ .. important::
+   The **GST** Report is not submitted directly to the **IRD** through Odoo. Instead, Odoo
+   automatically calculates the required values for each section, providing options to audit
+   and review the data for a clearer understanding of its history. Businesses can then
+   manually transfer these values to the `IRD portal <https://myir.ird.govt.nz/_/>`_.
+
+
+Remittance advice
+-----------------
+
+A remittance advice is a document used as proof of payment to a business. In Odoo, it can be
+accessed through :menuselection:`Accounting --> Vendors --> Payments`, selecting the payment(s),
+and clicking :menuselection:`Print -->Payment Receipt`.
+
+.. image:: new_zealand/remitance_advice.png
+   :alt: Remittance Advice.
+
+E-Invoicing
+===========
+
+PEPPOL
+------
+
+Odoo is compliant with Australia's and New Zealand's `PEPPOL requirements <https://peppol.org/learn-more/country-profiles/new-zealand/>`_.
+You can find and set up **electronic invoicing** settings per partner under
+:menuselection:`Accounting -->Customers` or :menuselection:`Accounting -->Vendors`, select a
+partner, and click the Accounting tab.
+
+.. image:: new_zealand/peppol_contact.png
+   :alt: Peppol Contact.
 
 .. important::
-   To :ref:`configure the Employment Hero API <employment_hero/configuration>` for **New Zealand**,
-   use the following value as :guilabel:`Payroll URL`: `https://api.nzpayroll.co.nz/`.
+   Validating an invoice or credit note for a partner on the PEPPOL network will download a
+   compliant XML file that can be manually uploaded to the PEPPOL network. Odoo is currently in the
+   process of becoming an access point for the ANZ region.
+
+EFT Batch Payments
+==================
+
+Introduction
+------------
+
+An EFT (electronic fund transfer) Batch file is a digital format used in New Zealand to facilitate
+bulk payment processing for businesses. It allows companies to consolidate multiple inbound and
+outbound payments into a single electronic file. This process is commonly used by businesses
+handling multiple payments at once, such as payroll or payments to multiple suppliers.
+
+Configuration
+-------------
+
+Settings
+~~~~~~~~
+
+ #. :ref:`Activate <general/install>` the EFT Batch Payment module (`l10n_nz_eft`).
+
+ .. image:: new_zealand/eft_batch_payment.png
+   :alt: EFT Batch Payment.
+
+#. Go to :menuselection:`Accounting --> Configuration --> Settings --> Customer Payments` to enable
+   **Batch Payments**.
+
+.. seealso::
+   - :doc:`../../../applications/finance/accounting/payments/batch`
+
+Bank journal
+~~~~~~~~~~~~
+
+Then, go to :menuselection:`Accounting --> Configuration --> Journals` to configure the Bank
+Account. In the :guilabel:`Journal Entries` tab, enter the :guilabel:`Account Number` and click
+:guilabel:`Create and Edit`. In the pop-up window, fill in the following fields:
+
+- :guilabel:`Bank`
+- :guilabel:`Account Number`
+
+ .. image:: new_zealand/bank_journal.png
+   :alt: Bank Journal.
+
+.. image:: new_zealand/create_account_number.png
+   :alt: Create Account Number.
+
+.. important::
+   Send Money defines the bank account as trusted, which is essential for EFT files and must be
+   enabled if it is to be used.
+
+.. note::
+   The Currency field is optional.
+
+Partners' bank accounts
+~~~~~~~~~~~~~~~~~~~~~~~
+
+To add banking information for a partner, navigate to
+:menuselection:`Accounting --> Customers --> Customers`,
+:menuselection:`Accounting --> Vendors --> Vendors`, or access the partner directly through the
+**Contacts** module. Select the relevant partner, then open the **Accounting** tab. Under the
+**Bank Accounts** section, click "**Add a line**" to enter the required details.
+
+- :guilabel:`Account Number`
+- :guilabel:`Bank`
+- :guilabel:`Account Holder` (it will automatically be selected for that partner)
+- The Send Money field must be **enabled**.
+
+.. image:: new_zealand/eft_partner_bank_account.png
+   :alt: EFT Partner Bank Account.
+
+Generate an EFT file
+--------------------
+
+Go to :menuselection:`Accounting --> Customers --> Invoices`
+or :menuselection:`Accounting --> Vendors --> Bills`, Select the Invoices/Bills you want to pay
+from the list. Once selected, click :guilabel:`Pay` and under Payment Method select
+**New Zealand EFT** and :guilabel:`Create Payment`.
+
+.. note::
+   The **Group Payment** checkbox is optional. This option appears only if there are multiple
+   invoices or bills from the same contact.
+
+.. image:: new_zealand/eft_file.png
+   :alt: EFT File
+
+Odoo will now open the Payments window. The same payment information can be found under
+:menuselection:`Accounting --> Customers --> Payments` or
+:menuselection:`Accounting --> Vendors --> Payments`. The required EFT information for each
+payment, such as **Particulars** and **Analysis Code**, can be entered as needed.
+
+.. image:: new_zealand/eft_payments.png
+   :alt: EFT Payments.
+
+After completing all required fields, return to the **Payments** list view, select the payments
+needing to batch, and click :menuselection:`Actions --> Create Batch Payment`.
+
+.. image:: new_zealand/eft_create_batch_payment.png
+   :alt: EFT Create Batch Payment.
+
+In the **Batch Payment** view, fill in the following fields:
+
+- :guilabel:`EFT File Format`
+- :guilabel:`Payment Reference`
+- :guilabel:`Payment Particulars`
+
+Once all information is completed, click :guilabel:`Validate`. Odoo will generate the EFT file in
+the chatter. Click on the file to preview or download it directly to your computer.
+
+.. important::
+   Each bank in New Zealand has its specific format requirements for EFT Batch Payments. Make sure
+   to choose the correct EFT file format. Some banks may also require you to fill in additional
+   fields, such as Direct Debit Information and Dishonour Account.
+
+.. image:: new_zealand/eft_file_in_chatter.png

+Industry-specific features
+==========================
+
+Starshipit Shipping
+-------------------
+
+Starshipit is a shipping service operator that facilitates the integration of Australasian
+shipping couriers with Odoo. See our dedicated documentation page.
+
+.. seealso::
+   - :doc:`../../../applications/inventory_and_mrp/inventory/shipping_receiving/setup_configuration/starshipit_shipping`
+   - `Starshipit Webinar <https://www.youtube.com/watch?v=TcDWnoYLXWg>`_
+
+Buy Now, Pay Later solutions
+----------------------------
+
+**Buy Now, Pay Later** solutions are popular payment methods for e-shops in New Zealand. Some of
+these solutions are available via the `Stripe <https://stripe.com/au/payments/payment-methods>`_
+and `AsiaPay payment <https://www.asiapay.com.au/payment.html#option>`_ providers.
+
+.. seealso::
+   - :doc:`AsiaPay Payment Provider <../../../applications/finance/payment_providers/asiapay>`
+   - :doc:`Stripe Payment Provider <../../../applications/finance/payment_providers/stripe>`
+
+POS terminals for New Zealand
+-----------------------------
+
+If you wish to have a direct connection between Odoo and your PoS terminal in New Zealand, you must
+have a **Stripe** terminal. Odoo supports the **EFTPOS** payment solution in New Zealand.
+
+.. note::
+   You do not need a Stripe payment terminal to use Odoo as your main PoS system. The only drawback
+   of not using Stripe is that cashiers must manually enter the final payment amount on the
+   terminal.
+
+.. seealso::

+
+Employment Hero Integration
+===========================
+
+If your business is already up and running with `Employment Hero <https://employmenthero.com/>`_,
+you can use our connector as an alternative payroll solution.
+
+The Employment Hero module synchronises payslip accounting entries (e.g., expenses, social charges,
+liabilities, taxes) automatically from **Employment Hero** to Odoo. Payroll administration is still
+done in **Employment Hero**. We only record the **journal entries** in Odoo.
+
+Configuration
+-------------
+
+#. :ref:`Activate <general/install>` the Employmen Hero Payroll module (`l10n_employment_hero`).
+#. Configure the **Employment Hero API** by going to
+   :menuselection:`Accounting --> Configuration --> Settings`. More fields become visible after
+   clicking on :guilabel:`Enable Employment Hero Integration`.
+
+   .. image:: new_zealand/enable_employment_hero_integration.png
+      :alt: Enable Employment Hero Integration.
+
+   - You can find the API Key in the My Account section of the Employment Hero platform.
+
+   .. image:: new_zealand/API_key_employment_hero.png
+      :alt: API Key Employment Hero.
+
+   - The Payroll URL is pre-filled with `Employment Hero Payroll <https://employmenthero.nzpayroll.co.nz/>`_
+
+   .. warning::
+       Do not modify the **pre-filled Payroll URL**.
+
+   - You can find the **Business ID** in the Employment Hero URL.(i.e., `189241`)
+
+   .. image:: new_zealand/employment_hero_business_ID_189241.png
+      :alt: Employment Hero Business ID.
+
+   - You can choose any Odoo journal to post the payslip entries.
+
+#. Configure the tax by going to :menuselection:`Accounting--> Configuration --> Taxes`. Create the
+   necessary taxes for the Employment Hero payslip entries. Fill in the tax code from **Employment
+   Hero** in the Matching Employment Hero Tax field.
+
+How does the API work?
+----------------------
+
+The API syncs the journal entries from **Employment Hero** to Odoo and leaves them in draft mode.
+The reference includes the Employment Hero payslip entry ID in brackets for the user to easily
+retrieve the same record in Employment Hero and Odoo.
+
+.. image:: new_zealand/employment_hero_odoo_journal_entries_API_sync.png
+   :alt: Employment Hero Odoo Journal Entries API Sync.
+
+By default, the synchronisation happens once per week. You can fetch the records manually through
+:menuselection:`Accounting --> Configuration --> Settings` and, in the
+:guilabel:`Enable Employment Hero Integration` option, click on :guilabel:`Fetch Payruns Manually`.
+
+Employment Hero payslip entries also work based on double-entry bookkeeping.
+
+The accounts used by Employment Hero are defined in the section Payroll settings.
+
+.. image:: new_zealand/employment_hero_settings.png
+   :alt: Employment Hero Settings.
+
+For the API to work, you need to create the same accounts as the default accounts of your
+Employment Hero business (**same name and same code**) in Odoo. You also need to choose the correct
+account types in Odoo to generate accurate financial reports.
