+# Purchase Custom Form Visibility
+
+Custom Odoo 19 module to dynamically manage the visibility of buttons and financial fields on the Purchase Order form on a per-user basis.
+
+## Features
+1. **Per-User Restricting Options**: Toggle restriction flags directly on individual user accounts.
+2. **Hide RFQ & Confirmation Buttons**: Hide "Confirm Order" and "Send RFQ" buttons from the purchase order header for restricted users.
+3. **Hide Financial Fields**: Hide unit price, subtotal, and totals on purchase lists, forms, line kanbans, and footer groups for restricted users.
+4. **Flexible and Stateless**: Instant dynamically computed restrictions without storing redundant data in the database.
+
+## Installation
+1. Move the `purchase_custom_visibility` directory to Odoo's custom addons path.
+2. Upgrade/Update Odoo addons list.
+3. Install the module.
+
+## Configuration (Per-User)
+1. Go to **Settings** -> **Users & Companies** -> **Users**.
+2. Select a User record and click **Edit**.
+3. Open the **Purchase Restrictions** tab.
+4. Check the desired restrictions:
+   - **Hide Confirm Order & Send RFQ**
+   - **Hide Price, Subtotal & Total**
+5. Save the user record.
