### Where KYC is Checked:

#### A. Checkout Page (`afinet-portal/src/app/(portal)/checkout/page.js`)
**Line 226-241:**
```javascript
// Check KYC status before proceeding
if (!kycStatus?.data?.completed) {
  setShowKYCModal(true);
  
  // Build a user-friendly message about missing documents
  const missing = [];
  if (!kycStatus?.data?.has_id) missing.push('ID document');
  if (!kycStatus?.data?.has_proof_of_residence) missing.push('proof of residence');
  if (!kycStatus?.data?.has_business_registration && kycStatus?.data?.requires_business_docs) {
    missing.push('business registration');
  }
  
  const missingDocs = missing.length > 0 
    ? `Missing: ${missing.join(', ')}` 
    : 'Please upload required documents';
  
  toast.error(`KYC verification required. ${missingDocs}`);
  return;
}
```

**Flow:**
1. Customer fills checkout form
2. Clicks "Proceed to Payment"
3. System checks KYC status
4. If incomplete → Shows KYC upload modal
5. Customer uploads missing documents
6. After upload → Can proceed to payment

#### B. Quotation Acceptance (`afinet-portal/src/app/(portal)/quotations/[id]/page.js`)
**Line 48-51:**
```javascript
// Check KYC status first
if (!kycStatus?.completed) {
  toast.success('KYC verification simulated - proceeding to check MSA requirement');
}
```

**Flow:**
1. Customer views quotation
2. Clicks "Accept Quotation"
3. System checks KYC status
4. If incomplete → Shows KYC upload modal
5. Customer uploads missing documents
6. After upload → Can accept quotation

### KYC Upload Modal

## Backend Implementation

### KYC Status Check (`Customer.php` - Line 291-320)
```php
public function getKYCStatus()
{
    $requiredDocs = ['id', 'proof_of_residence'];
    if ($this->type === 'wholesale') {
        $requiredDocs[] = 'business_registration';
    }

    $verifiedTypes = $this->verifiedDocuments()
        ->pluck('document_type')
        ->toArray();

    $hasId = count(array_intersect(['national_id', 'passport', 'drivers_license'], $verifiedTypes)) > 0;
    $hasProof = in_array('proof_of_residence', $verifiedTypes);
    $hasBusiness = $this->type !== 'wholesale' || in_array('business_registration', $verifiedTypes);

    $completed = $hasId && $hasProof && $hasBusiness;

    return [
        'completed' => $completed,
        'has_id' => $hasId,
        'has_proof_of_residence' => $hasProof,
        'has_business_registration' => $hasBusiness,
        'pending_documents' => $this->documents()->where('status', 'pending')->count(),
        'verified_documents' => $this->verifiedDocuments()->count(),
    ];
}
```

### API Endpoints:

## Customer Type Determination

### How System Identifies Customer Type:
The `type` field in `customers` table determines the customer type:
- `'wholesale'` - Wholesale/B2B partners
- `'business'` - Business customers
- `'retail'` - Individual/retail customers

### KYC Requirements by Type:
| Customer Type | ID Document | Proof of Residence | Business Registration |
|--------------|-------------|-------------------|----------------------|
| Wholesale    | ✅ (at registration) | ✅ (at registration) | ✅ (at registration) |
| Business     | ✅ (before purchase) | ✅ (before purchase) | ✅ (before purchase) |
| Retail       | ✅ (before purchase) | ✅ (before purchase) | ❌ Not required |
