" reports missing"; } ``` ### Example 4: Inventory Alert ```php // Get low stock warnings $alerts = $inventoryHealthService->getLowStockAlerts(7); // < 7 days foreach ($alerts as $alert) { if ($alert['alert_level'] === 'critical') { // Trigger immediate restock order } } ``` --- ## 🎯 Key Features Implemented | Feature | Service | Endpoints | Status | |---------|---------|-----------|--------| | Monthly Performance | PerformanceScorecardService | 1 | ✅ | | Yearly Performance | PerformanceScorecardService | 1 | ✅ | | Performance Dashboard | PerformanceScorecardService | 1 | ✅ | | Target Projection | TargetProjectionService | 3 | ✅ | | Compliance Tracking | ComplianceTrackingService | 4 | ✅ | | Weekly Reports | ComplianceTrackingService | 1 | ✅ | | Product Performance | ProductAnalyticsService | 5 | ✅ | | Deadstock Detection | ProductAnalyticsService | 1 | ✅ | | Return Simulation | ReturnSimulationService | 3 | ✅ | | Inventory Health | InventoryHealthService | 5 | ✅ | **Total: 25 API Endpoints** --- ## 🔐 Authorization - **Public**: Auth endpoints - **Partner**: Can view own performance, compliance, projections, returns - **Admin**: Can view all partner data + dashboards + product analytics Routes are protected with `auth:sanctum` middleware. Admin routes require additional `admin` middleware. --- ## 📈 Calculation Methodology ### Target Achievement Percentage ``` achievement_percent = (sales_to_date / target) × 100 ``` ### Projection Formula ``` daily_average = sales_so_far / days_elapsed projected_total = sales_so_far + (daily_average × days_remaining) ``` ### Return Calculation ``` If achievement_percent >= 85: return = sales × tier_return_percentage Else: return = (sales × tier_return_percentage) × (achievement_percent / 85) ``` ### Compliance Percentage ``` compliance_percent = (submitted_weeks / 52) × 100 ``` ### Days of Stock Remaining ``` days_remaining = current_inventory / daily_average_consumption ``` --- ## 🚀 Usage Examples ### Frontend Integration (React) ```javascript // Get partner performance const response = await fetch( `/api/analytics/performance/yearly/1/2026`, { headers: { Authorization: `Bearer ${token}` } } ); const { data: scorecard } = await response.json(); // Show metrics ``` ### Testing Services ```php // In test $partner = Partner::factory()->create(); $service = new PerformanceScorecardService(); $scorecard = $service->getMonthlyScorecard($partner, now()); $this->assertIsArray($scorecard); $this->assertArrayHasKey('current_month_sales', $scorecard); ``` --- ## 📝 Future Enhancements 1. **Caching**: Cache expensive dashboard queries 2. **Export**: CSV/PDF export for reports 3. **Alerts**: Email/SMS notifications for compliance & projections 4. **Forecasting**: ML-based sales forecasting 5. **Benchmarking**: Compare partner performance vs peer group 6. **Incentives**: Automatic bonus calculations based on tier --- ## ✨ Architecture Highlights ✅ **Separation of Concerns**: Services handle all business logic ✅ **Reusable**: Services used by controllers and other parts of app ✅ **Testable**: Each service method is independently testable ✅ **Scalable**: Easy to add new analytics features ✅ **Type-Safe**: Strong typing with PHP 8.1+ ✅ **Well-Documented**: Every method has docstrings ✅ **RESTful**: Standard REST API conventions --- This completes the architecture implementation from the ChatGPT design document. All 6 major features are fully implemented with comprehensive service layer, controllers, and API endpoints.
