## Odoo Integration Points

### Customer Management
- **Create Customer:** `OdooService::createCustomer()`
- **Sync Customer Data:** `OdooService::syncCustomerData()`
- **Get Customer Info:** `OdooService::getCustomerById()`

### Quotation Management
- **Create Quotation:** `OdooService::createQuotation()`
- **Convert to Sales Order:** `OdooService::convertQuotationToSaleOrder()`

## Testing Results

### Simple Workflow Test ✅
```
✅ Customer registration (with Odoo sync)
✅ Feasibility check performed
✅ Package selection based on feasibility
✅ Quotation created (with Odoo sync)
✅ Quotation accepted and converted to sales order
✅ Payment processed and order completed
✅ All data properly stored and linked
```

### API Endpoints Test ✅
```
✅ Registration API - Creates customer and syncs with Odoo
✅ Dashboard API - Shows customer stats and activity
✅ Feasibility Check API - Validates service address
✅ Quotation Request API - Creates quotation in Portal and Odoo
