## 🔧 Technical Implementation

### Frontend Changes (`resources/js/pages/pos/POS.vue`)

**New State Variables:**
```javascript
const customerSearch = ref('');          // Search input value
const filteredCustomers = ref([]);       // Filtered results
const showCustomerDropdown = ref(false); // Show/hide dropdown
const customerInfo = ref({               // Customer info fields
  name: '',
  phone: ''
});
```

**New Functions:**

1. **filterCustomers()** - Filters customers based on search query
   ```javascript
   // Searches name and phone, shows top 10 matches
   ```

2. **selectCustomer(customer)** - Selects customer from dropdown
   ```javascript
   // Sets selected customer and prefills info fields
   ```

3. **clearCustomerSelection()** - Clears customer selection
   ```javascript
   // Resets all customer-related fields
   ```

4. **createCustomerIfNeeded()** - Auto-creates customer if needed
   ```javascript
   // Creates customer if name provided but not selected
   // Called before completing sale
   ```

### Backend Changes

**`app/Http/Controllers/Api/CustomerController.php`:**
- Updated `store()` method to allow salespeople to create customers
- Maintains proper authorization for customer management pages
- Allows customer creation during POS transactions
