+# VAT Settings + RFQ Per-Item Vatable Checkbox — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add a global VAT rate setting and per-item vatable checkboxes on the supplier RFQ portal, with live VAT breakdown in totals.
+
+**Architecture:** Global VAT rate stored in existing `settings` key/value table. Per-item `is_vatable` flag added to `supplier_quote_items`. RFQ portal view updated with checkbox column and three-row footer (subtotal / VAT / grand total). New `VatSettingController` + `settings/vat` page added under the Admin-only System sidebar section.
+
+**Tech Stack:** Laravel 12, PHP 8.2, SQLite, Blade, Alpine-free vanilla JS, Tailwind (inline styles per project convention)
+
+---
+
+### Task 1: Migration — add `is_vatable` to `supplier_quote_items`
+
+**Files:**
+- Modify: `database/migrations/2026_06_01_090734_add_is_vatable_to_supplier_quote_items.php`
+- Modify: `app/Models/SupplierQuoteItem.php`
+
+- [ ] **Step 1: Write the migration**
+
+Replace the generated migration body with:
+
+```php
+<?php
+
+use Illuminate\Database\Migrations\Migration;
+use Illuminate\Database\Schema\Blueprint;
+use Illuminate\Support\Facades\Schema;
+
+return new class extends Migration
+{
+    public function up(): void
+    {
+        Schema::table('supplier_quote_items', function (Blueprint $table) {
+            $table->boolean('is_vatable')->default(false)->after('total_price');
+        });
+    }
+
+    public function down(): void
+    {
+        Schema::table('supplier_quote_items', function (Blueprint $table) {
+            $table->dropColumn('is_vatable');
+        });
+    }
+};
+```
+
+- [ ] **Step 2: Run migration**
+
+```bash
+php artisan migrate
+```
+
+Expected: `Migrating: 2026_06_01_090734_add_is_vatable_to_supplier_quote_items` then `Migrated`.
+
+- [ ] **Step 3: Update SupplierQuoteItem model**
+
+In `app/Models/SupplierQuoteItem.php`, update `$fillable`:
+
+```php
+protected $fillable = [
+    'supplier_quote_id', 'description', 'unit', 'quantity', 'unit_price', 'total_price', 'is_vatable',
+];
+
+protected $casts = [
+    'is_vatable' => 'boolean',
+];
+```
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add database/migrations/2026_06_01_090734_add_is_vatable_to_supplier_quote_items.php app/Models/SupplierQuoteItem.php
+git commit -m "feat: add is_vatable column to supplier_quote_items"
+```
+
+---
+
+### Task 2: VatSettingController + route + view
+
+**Files:**
+- Create: `app/Http/Controllers/Settings/VatSettingController.php`
+- Create: `resources/views/settings/vat.blade.php`
+- Modify: `routes/web.php`
+
+- [ ] **Step 1: Create VatSettingController**
+
+Create `app/Http/Controllers/Settings/VatSettingController.php`:
+
+```php
+<?php
+
+namespace App\Http\Controllers\Settings;
+
+use App\Http\Controllers\Controller;
+use App\Models\Setting;
+use Illuminate\Http\Request;
+
+class VatSettingController extends Controller

+    {
+        $vatRate = Setting::get('vat_rate', '0');
+        return view('settings.vat', compact('vatRate'));
+    }
+
+    public function update(Request $request)
+    {
+        $validated = $request->validate([
+            'vat_rate' => ['required', 'numeric', 'min:0', 'max:100'],
+        ]);
+
+        Setting::set('vat_rate', (string) $validated['vat_rate']);
+
+        return response()->json(['message' => 'VAT rate saved.', 'vat_rate' => $validated['vat_rate']]);
+    }
+}
+```
+
+- [ ] **Step 2: Add routes**
+
+In `routes/web.php`, after the integrations routes (around line 148), add:
+
+```php
+// VAT settings
+Route::get('settings/vat',  [VatSettingController::class, 'index'])->name('settings.vat');
+Route::post('settings/vat', [VatSettingController::class, 'update'])->name('settings.vat.update');
+```
+
+Also add the import at the top of the file with the other Settings controllers:
+```php
+use App\Http\Controllers\Settings\VatSettingController;
+```
+
+- [ ] **Step 3: Create the VAT settings view**
+
+Create `resources/views/settings/vat.blade.php`:
+
+```blade

+### Task 4: Update RfqPortalController — load VAT rate and store is_vatable
+
+**Files:**
+- Modify: `app/Http/Controllers/Purchase/RfqPortalController.php`
+
+- [ ] **Step 1: Update show() to pass VAT rate**
+
+Add `use App\Models\Setting;` at the top of the file.
+
+Update the `show()` method — add before the `return view(...)` line:
+
+```php
+$vatRate = (float) Setting::get('vat_rate', 0);
+```
+
+Update the return to:
+
+```php
+return view('rfq.show', compact('invitation', 'purchaseRequest', 'items', 'confirmCode', 'vatRate'));
+```
+
+- [ ] **Step 2: Update submit() to store is_vatable and calculate VAT-inclusive total**
+
+Add `'items.*.is_vatable' => ['nullable', 'boolean']` to the validation rules array.
+
+Replace the items loop and total calculation:
+
+```php
+$subtotal = 0;
+$vatAmount = 0;
+$vatRate = (float) Setting::get('vat_rate', 0);
+
+foreach ($purchaseItems as $i => $item) {
+    $unitPrice  = (float)($validated['items'][$i]['unit_price'] ?? 0);

+    $subtotal  += $totalPrice;
+
+    if ($isVatable && $vatRate > 0) {

+
+$grand = round($subtotal + $vatAmount, 3);

+
+```bash

+
+### Task 5: Update rfq/show.blade.php — checkbox column + VAT footer + JS
+
+**Files:**
+- Modify: `resources/views/rfq/show.blade.php`
+
+- [ ] **Step 1: Add VAT rate JS variable**
+
+At the start of the `<script>` block, add:
+
+```javascript
+var _vatRate = {{ $vatRate }};
+```
+
+- [ ] **Step 2: Replace calcRow() and add recalcTotals()**
+
+Replace the entire `calcRow` function and grand total logic with:
+
+```javascript
+var _totals    = {};
+var _vatable   = {};
+
+function calcRow(i, qty) {
+    var inp = document.querySelector('input[name="items[' + i + '][unit_price]"]');
+    var cb  = document.querySelector('input[name="items[' + i + '][is_vatable]"]');

+    _totals[i]  = tot;
+    _vatable[i] = cb ? cb.checked : false;
+    var el = document.getElementById('tot-' + i);
+    if (el) el.textContent = tot > 0 ? 'BD ' + tot.toFixed(3) : '—';

+
+    var elSub = document.getElementById('subtotal-row');

+    }
+    if (elGrand) elGrand.textContent = 'BD ' + grand.toFixed(3);
+}
+```
+
+- [ ] **Step 3: Update table header**
+
+Replace the `<thead>` block:
+
+```html
+<thead>
+    <tr>
+        <th>#</th>
+        <th>Description</th>
+        <th>Qty</th>
+        <th>Unit</th>

+        <th style="text-align:right;">Total (BD)</th>
+    </tr>
+</thead>
+```
+
+- [ ] **Step 4: Update each item row**
+
+Replace the `@foreach` tbody rows:
+
+```blade
+@foreach($items as $i => $item)
+<tr>
+    <td style="color:#94a3b8;font-size:12px;">{{ $i + 1 }}</td>
