## Business Logic

### MSA Requirement Rules

#### MEDIUM Feasibility
- ✅ Always requires MSA
- Reason: Needs installation/extension work

#### HIGH Feasibility
- ✅ Requires MSA if:
  - First time installation (no completed installations)
  - Physical work required (installations, services, fixes)
- ✅ NOT required for:
  - Simple resubscription (already installed, just renewing)

#### LOW Feasibility
- ✅ Requires MSA when accepting alternative products

---

## Integration Flow

### Quotation Acceptance Flow
```
1. Customer clicks "Accept Quotation"
   ↓
2. System checks: Is MSA required?
   - Call: GET /api/msa/quotation/{id}/check
   ↓
3. If MSA required:
   - Show MSA signing modal
   - Customer completes 3 steps
   - System creates draft MSA
   ↓
4. Customer fills information
   - Pre-filled from profile
   - Validates all fields
   - Saves to backend
   ↓
5. Customer signs
   - Draws signature on canvas
   - Converts to image
   - Uploads to backend
   ↓
6. System completes signing
   - Generates PDF
   - Uploads to Odoo
   - Sends confirmation email
   - Links to quotation/order
   ↓
7. Quotation accepted
   - Order created
   - Customer notified
```

## Next Steps

### 1. Integration with Quotation Page
**File to update**: `afinet-portal/src/app/(portal)/quotations/[id]/page.js`

**Add**:
```javascript
import MsaSigningModal from '@/components/modals/msa-signing-modal';

// State
const [showMsaModal, setShowMsaModal] = useState(false);
const [msaRequired, setMsaRequired] = useState(false);

// Check if MSA required
const checkMsaRequired = async () => {
  const response = await fetch(`/api/msa/quotation/${quotationId}/check`);
  const data = await response.json();
  setMsaRequired(data.required);
  return data.required;
};

// On Accept Quotation
const handleAcceptQuotation = async () => {
  const required = await checkMsaRequired();
  
  if (required) {
    setShowMsaModal(true);
  } else {
    // Proceed with normal acceptance
    acceptQuotation();
  }
};

// MSA Complete Handler
const handleMsaComplete = (msa) => {
  // MSA signed, now accept quotation
  acceptQuotation();
};

// Render
<MsaSigningModal
  isOpen={showMsaModal}
  onClose={() => setShowMsaModal(false)}
  quotationId={quotationId}
  onComplete={handleMsaComplete}
/>
```

### 2. Install PDF Library
```bash
cd afinet-portal-backend
composer require barryvdh/laravel-dompdf
```

### 3. Configure PDF Library
**File**: `config/app.php`
```php
'providers' => [
    // ...
    Barryvdh\DomPDF\ServiceProvider::class,
],

'aliases' => [
    // ...
    'PDF' => Barryvdh\DomPDF\Facade\Pdf::class,
],
```

### 4. Test the Flow
1. Create a quotation with MEDIUM feasibility
2. Click "Accept Quotation"
3. MSA modal should open
4. Complete all 3 steps
5. Sign the agreement
6. Check database for MSA record
7. Check storage for PDF file
8. Check Odoo for attachment

## API Testing

### Test MSA Requirement Check

```

### Test Signature Upload
