# Router Options & Value-Added Services Fix

## Issue
Router rental fees and value-added services were not being included in the checkout pricing calculations, causing inconsistency between cart and checkout pages.

## What Was Fixed

### Checkout Page (`afinet-portal/src/app/(portal)/checkout/page.js`)

#### 1. Updated `calculateTotals` Function
Added calculations for:
- **Router Monthly Fees**: $5/month when router option is 'rent'
- **Value-Added Services**: Sum of all selected service prices
- **Package Monthly**: Base package subscription price

```javascript
// Before: Only calculated package monthly
const recurringCharge = items.reduce((acc, item) => {
  const monthlyPrice = parseFloat(item.monthly_price) || 0;
  return acc + monthlyPrice;
}, 0);

// After: Includes router rental + services
const packageMonthly = items.reduce(...);
const routerMonthly = items.reduce((acc, item) => {
  return acc + (item.routerOption === 'rent' ? 5 : 0);
}, 0);
const servicesMonthly = items.reduce((acc, item) => {
  const services = item.valueAddedServices || [];
  return acc + services.reduce((sum, s) => sum + s.price, 0);
}, 0);
const recurringCharge = packageMonthly + routerMonthly + servicesMonthly;
```

#### 2. Updated Order Summary Display
Now shows detailed breakdown:
- Package Monthly
- Router Rental (if applicable)
- Value-Added Services (if applicable)
- Total Recurring Monthly (sum of above)
- Initial One-Time Charges
- VAT (16%)
- Total Due Today

### Cart Page (`afinet-portal/src/app/(portal)/cart/page.js`)
Already had correct logic - no changes needed.

## How It Works Now

### Router Options:
- **Rent**: $5/month added to recurring charges, $0 one-time
- **Purchase**: $150 one-time added to initial charges, $0/month

### Value-Added Services:
Each selected service adds its monthly price to recurring charges:
- Static IP Address: +$10/month
- Premium Support: +$15/month
- Advanced Security: +$20/month

## Example Calculation

### Scenario: Starlink + Router Rental + Static IP
- Package Monthly: $120.00
- Router Rental: $5.00
- Static IP: $10.00
- **Total Recurring Monthly: $135.00**

- Installation Fee: $150.00
- Router Purchase: $0.00 (renting)
- Extension Cost: $0.00
- **Initial One-Time: $150.00**

- VAT (16% on initial): $24.00
- **Total Due Today: $174.00**

### Scenario: Starlink + Router Purchase + Premium Support + Advanced Security
- Package Monthly: $120.00
- Router Rental: $0.00 (purchased)
- Premium Support: $15.00
- Advanced Security: $20.00
- **Total Recurring Monthly: $155.00**

- Installation Fee: $150.00
- Router Purchase: $150.00
- Extension Cost: $0.00
- **Initial One-Time: $300.00**

- VAT (16% on initial): $48.00
- **Total Due Today: $348.00**

## Testing Instructions

1. **Clear cart**: 
   ```javascript
   localStorage.removeItem('cart-storage')
   ```

2. **Add a package** (e.g., Starlink) to cart

3. **In cart page**:
   - Select "Rent Router" option
   - Check "Static IP Address" service
   - Verify totals show:
     - Package Monthly: $120
     - Router Rental: $5
     - Value-Added Services: $10
     - Total Monthly: $135

4. **Go to checkout**:
   - Verify same breakdown appears
   - Verify "Total Recurring Monthly" = $135
   - Verify consistency with cart page

5. **Change to "Purchase Router"**:
   - Go back to cart
   - Select "Purchase Router"
   - Verify Initial One-Time increases by $150
   - Verify Router Rental line disappears from monthly

6. **Add more services**:
   - Check "Premium Support" and "Advanced Security"
   - Verify each adds to monthly total
   - Verify checkout matches cart

## Files Modified
- ✅ `afinet-portal/src/app/(portal)/checkout/page.js` - Updated calculateTotals and order summary display

## Files Already Correct
- ✅ `afinet-portal/src/app/(portal)/cart/page.js` - Already had correct logic

## Status
✅ **COMPLETE** - Router options and value-added services now properly included in checkout pricing
✅ **Cart and Checkout Consistent** - Both pages show identical calculations
⚠️ **Action Required** - Clear cart and re-add items to test the fix
