From 73dfeecbaaf792b493c071d86026fa50764fce61 Mon Sep 17 00:00:00 2001 From: Dries Peeters Date: Sun, 23 Nov 2025 18:39:22 +0100 Subject: [PATCH] feat: Complete inventory management system implementation Add comprehensive inventory management system with full feature set including stock tracking, warehouse management, supplier management, purchase orders, transfers, adjustments, and reporting. Core Features: - Stock Items: Full CRUD operations with categories, SKU, barcodes, pricing - Warehouse Management: Multi-warehouse support with stock level tracking - Supplier Management: Multi-supplier support with supplier-specific pricing - Purchase Orders: Complete PO lifecycle (draft, sent, received, cancelled) - Stock Transfers: Transfer stock between warehouses with audit trail - Stock Adjustments: Dedicated interface for stock corrections - Stock Reservations: Reserve stock for quotes/invoices/projects - Movement History: Complete audit trail for all stock movements - Low Stock Alerts: Automated alerts when items fall below reorder point Reports & Analytics: - Inventory Dashboard: Overview with key metrics and statistics - Stock Valuation: Calculate total inventory value by warehouse/category - Movement History Report: Detailed movement log with filters - Turnover Analysis: Inventory turnover rates and sales analysis - Low Stock Report: Comprehensive low stock items listing Integration: - Quote Integration: Stock reservation when quotes are created - Invoice Integration: Automatic stock reduction on invoice payment - Project Integration: Stock allocation for project requirements - API Endpoints: RESTful API for suppliers, purchase orders, and inventory Technical Implementation: - 9 new database models with proper relationships - 3 Alembic migrations for schema changes - 60+ new routes for inventory management - 20+ templates for all inventory features - Comprehensive permission system integration - CSRF protection on all forms - Full menu navigation integration Testing: - Unit tests for inventory models - Route tests for inventory endpoints - Integration tests for quote/invoice stock integration Documentation: - Implementation plan document - Missing features analysis - Implementation status tracking --- app/__init__.py | 2 + app/models/__init__.py | 19 + app/models/extra_good.py | 10 +- app/models/invoice.py | 17 +-
