+This module extends the functionality of the e-commerce platform to
+support country-specific tax identifiers and to allow users to see
+localized labels for the VAT field during the checkout process.
+
+By default, Odoo uses a generic "VAT" label in the billing and shipping
+address forms, regardless of the customer's country. This module
+overrides that behavior by dynamically checking if the selected country
+has a custom VAT label defined in its backend configuration (such as
+"RUT", "CPF", "NIF", or "EIN") and displays it directly to the customer
+on the website.
+
+This enhancement significantly improves the user experience during
+registration and checkout, reducing confusion for international
+customers and ensuring higher data accuracy for B2B transactions by
+matching official local terminology.

+
+Use Cases / Context
+===================
+
+Business Need
+~~~~~~~~~~~~~
+
+In many countries, the term "VAT" (Value Added Tax) is not commonly used
+or recognized by local citizens and businesses. For instance, companies
+and customers in Chile look for "RUT", in Brazil for "CPF/CNPJ", in
+Spain for "NIF/CIF", and in the United States for "EIN".
+
+When an international or localized e-commerce website forces users to
+fill out a field labeled generically as "VAT", it creates friction and
+confusion during the checkout process. Users are often unsure whether
+they should enter their personal ID, corporate tax number, or if the
+field even applies to them. This module resolves this issue by
+automatically adapting the form terminology to match local expectations
+based on the selected country, thereby reducing cart abandonment and
+improving data quality at registration.
+
+Approach
+~~~~~~~~
+
+This module extends the standard Odoo website address rendering
+controller. It intercepts the dictionary of values sent to the frontend
+address form template (``_prepare_address_form_values``) and dynamically
+replaces the static 'VAT' string label. It fetches the ``vat_label``
+field configured on the selected country's backend record
+(``res.country``). If a specific label is defined for that country, it
+is displayed; otherwise, it seamlessly falls back to the standard "VAT"
+term.
+
+Useful Information
+~~~~~~~~~~~~~~~~~~
+
+- **Dependencies:** This module directly extends ``website_sale`` (the
+  core Odoo eCommerce module) and relies on the base ``res.country``
+  model features.
+- **Recommended Setups:**
+
+  - **Multi-website:** Highly recommended for businesses running
+    multiple localized websites targeting different regions or countries
+    from a single Odoo database.
+  - **B2B Portals:** Essential for companies with a heavy B2B focus
+    where accurate tax identification is mandatory for automated
+    invoicing.
+
+- **Complementary Modules:** This module pairs perfectly with OCA
+  localization modules (such as ``l10n_br_website_sale`` or equivalent
+  local modules) that enforce specific tax validation rules, ensuring
+  that the field not only looks right but also validates correctly
+  according to local laws.
+
+Usage
+=====
+
+To use this module, you need to:
+
+1. **Configure the Country VAT Label (Backend):**
+
+   - Go to **Contacts** > **Configuration** > **Countries**.
+   - Search for and select the country you want to configure (e.g.,
+     *Brazil* or *Chile*).
+   - In the form view, locate the **VAT Label** field and enter the
+     local terminology (e.g., *CPF/CNPJ* or *RUT*).
+   - Click **Save**.
+
+   |Configure Country VAT Label in Backend|
+
+2. **Check the Website Checkout/Address Form (Frontend):**
+
+   - Go to your **Website** shop.
+   - Add any product to the cart and proceed to the **Checkout**.
+   - On the **Billing/Shipping Address** form, select the country you
+     configured in step 1.
+   - You will notice that the standard generic **"VAT"** input field
+     label dynamically changes to match the localized label you defined
+     (e.g., *RUT* or *CPF/CNPJ*).
