## 🎯 Commission System Flow (One Example)

```
1. Admin creates Connector
   ↓
2. Connector configures commission (e.g., 10% of service price)
   ↓
3. Connector brings a client
   ↓
4. Client purchases service for ₹5000
   ↓
5. Order created & assigned to connector
   ↓
6. Order marked as complete
   ↓
7. AUTOMATIC: Backend calculates
   Commission = 5000 * 10% = ₹500
   ↓
8. Commission record created with status 'pending'
   ↓
9. Connector sees in dashboard:
   - Total Earnings: ₹500
   - Pending: ₹500
   ↓
10. Admin reviews & marks as 'paid'
    ↓
11. Connector sees:
    - Paid: ₹500
    - Pending: ₹0
```
