+- PostgreSQL databases per service with proper migrations
+- RabbitMQ message queuing for inter-service communication
+- Monitoring with Prometheus and Grafana
+- Comprehensive error handling and logging
+
+### ❌ **Critical Missing Features for MVP Launch**
+
+## 1. **INVENTORY MANAGEMENT SYSTEM** 🚨 **HIGHEST PRIORITY**
+
+### **Problem Identified**: 
+According to the bakery research, manual inventory tracking is described as "too cumbersome," "time-consuming," and highly susceptible to "mistakes." This leads to:
+- 1.5% to 20% losses due to spoilage and waste
+- Production delays during peak hours 
+- Quality inconsistencies
+- Lost sales opportunities
+
+### **Missing Components**:
+- **Ingredient tracking**: Real-time stock levels for flour, yeast, dairy products
+- **Automatic reordering**: FIFO/FEFO expiration date management
+- **Spoilage monitoring**: Track and predict ingredient expiration
+- **Stock alerts**: Low stock warnings integrated with production planning
+- **Barcode/QR scanning**: Easy inventory updates without manual entry
+- **Supplier integration**: Automated ordering from suppliers like Harinas Castellana
+
+### **Required Implementation**:
+```
+Backend Services Needed:
+- Inventory Service (new microservice)
+- Supplier Service (new microservice) 
+- Integration with existing Forecasting Service
+
+Frontend Components Needed:
+- Real-time inventory dashboard
+- Mobile-friendly inventory scanning
+- Automated reorder interface
+- Expiration date tracking
+```
+
+## 2. **RECIPE & PRODUCTION MANAGEMENT** 🚨 **HIGH PRIORITY**
+
+### **Problem Identified**:
+Individual bakeries struggle with production planning complexity due to:
+- Wide variety of products with different preparation times
+- Manual calculation of ingredient quantities
+- Lack of standardized recipes affecting quality consistency
+
+### **Missing Components**:
+- **Digital recipe management**: Store recipes with exact measurements
+- **Bill of Materials (BOM)**: Automatic ingredient calculation based on production volume
+- **Yield tracking**: Compare actual vs. expected production output
+- **Cost calculation**: Real-time cost per product based on current ingredient prices
+- **Production workflow**: Step-by-step production guidance
+- **Quality control**: Track temperature, humidity, timing parameters
+
+## 3. **SUPPLIER & PROCUREMENT SYSTEM** 🚨 **HIGH PRIORITY**
+
+### **Problem Identified**:
+Research shows small bakeries face "low buyer power" and struggle with:
+- Manual ordering processes via phone/WhatsApp
+- Difficulty tracking supplier performance
+- Limited negotiation power with suppliers
+
+### **Missing Components**:
+- **Supplier database**: Contact information, lead times, reliability ratings
+- **Purchase order system**: Digital ordering with approval workflows  
+- **Price comparison**: Compare prices across multiple suppliers
+- **Delivery tracking**: Monitor order status and delivery reliability
+- **Payment terms**: Track payment schedules and supplier agreements
+- **Performance analytics**: Supplier reliability and cost analysis
+
+## 4. **SALES DATA INTEGRATION** 🚨 **HIGH PRIORITY**
+
+### **Problem Identified**:
+Current forecasting relies on manual data entry. Research shows bakeries need:
+- Integration with POS systems
+- Historical sales pattern analysis
+- External factor correlation (weather, events, holidays)
+
+### **Missing Components**:
+- **POS Integration**: Automatic sales data import from common Spanish POS systems
+- **Manual sales entry**: Simple interface for bakeries without POS
+- **Product categorization**: Organize sales by bread types, pastries, seasonal items
+- **Customer analytics**: Track popular products and buying patterns
+- **Seasonal adjustments**: Account for holidays, local events, weather impacts
+
+## 5. **WASTE TRACKING & REDUCTION** 🚨 **MEDIUM PRIORITY**
+
+### **Problem Identified**:
+Research indicates waste reduction potential of 20-40% through AI optimization:
+- Unsold products (1.5% of production)
+- Ingredient spoilage
+- Production errors
+
+### **Missing Components**:
+- **Daily waste logging**: Track unsold products, spoiled ingredients
+- **Waste analytics**: Identify patterns in waste generation
+- **Dynamic pricing**: Reduce prices on items approaching expiration
+- **Donation tracking**: Manage food donations to reduce total waste
+- **Cost impact analysis**: Calculate financial impact of waste reduction
+
+## 6. **MOBILE-FIRST INTERFACE** 🚨 **MEDIUM PRIORITY**
+
+### **Problem Identified**:
+Research emphasizes bakery owners work demanding schedules starting at 4:30 AM and need "mobile accessibility" for on-the-go management.
+
+### **Missing Components**:
+- **Mobile-responsive design**: Current frontend is not optimized for mobile
+- **Offline capabilities**: Work without internet connection
+- **Quick actions**: Fast inventory checks, order placement
+- **Voice input**: Hands-free operation in production environment
+- **QR code scanning**: For inventory and product management
+
+## 7. **FINANCIAL MANAGEMENT** 🚨 **LOW PRIORITY**
+
+### **Problem Identified**:
+With 75-85% of revenue consumed by operating costs and 4-9% profit margins, bakeries need precise cost control.
+
+### **Missing Components**:
+- **Cost tracking**: Monitor food costs (25-35% of sales) and labor costs (24-40% of sales)
+- **Profit analysis**: Real-time profit margins per product
+- **Budget planning**: Monthly expense forecasting
+- **Tax preparation**: VAT calculations, expense categorization
+- **Financial reporting**: P&L statements, cash flow analysis
+
+## Implementation Priority Matrix
+
+| Feature | Business Impact | Technical Complexity | Implementation Time | Priority |
+|---------|----------------|---------------------|-------------------|----------|
+| Inventory Management | Very High | Medium | 6-8 weeks | 1 |
+| Recipe & BOM System | Very High | Medium | 4-6 weeks | 2 |
+| Supplier Management | High | Low-Medium | 4-5 weeks | 3 |
+| Sales Data Integration | High | Medium | 3-4 weeks | 4 |
+| Waste Tracking | Medium | Low | 2-3 weeks | 5 |
+| Mobile Optimization | Medium | Medium | 4-6 weeks | 6 |
+| Financial Management | Low | High | 8-10 weeks | 7 |
+
+## Technical Architecture Requirements
+
+### New Microservices Needed:
+1. **Inventory Service** - Real-time stock management, expiration tracking
+2. **Recipe Service** - Digital recipes, BOM calculations, cost management  
+3. **Supplier Service** - Supplier database, purchase orders, performance tracking
+4. **Integration Service** - POS system connectors, external data feeds
+
+### Database Schema Extensions:
+- Products table with recipes and ingredient relationships
+- Inventory transactions with batch/lot tracking
+- Supplier master data with performance metrics
+- Purchase orders with approval workflows
+
+### Frontend Components Required:
+- Mobile-responsive inventory management interface
+- Recipe editor with drag-drop ingredient addition
+- Supplier portal for order placement and tracking
+- Real-time dashboard with critical alerts
+
+## MVP Launch Recommendations
+
+### Phase 1 (8-10 weeks): Core Operations
+- Implement Inventory Management System
+- Build Recipe & BOM functionality  
+- Create Supplier Management portal
+- Mobile UI optimization
+
+### Phase 2 (4-6 weeks): Data Integration
+- POS system integrations
+- Enhanced sales data processing
+- Waste tracking implementation
+
+### Phase 3 (6-8 weeks): Advanced Features
+- Financial management tools
+- Advanced analytics and reporting
+- Performance optimization
+
+## Conclusion
+
+The current platform has excellent technical foundations but lacks the core operational features that small Madrid bakeries desperately need. The research clearly shows that **inventory management inefficiencies are the #1 pain point**, causing 1.5-20% losses and significant operational stress.
+
+**Without implementing inventory management, recipe management, and supplier systems, the platform cannot deliver the value proposition of waste reduction and cost savings that bakeries require for survival.**
+
+The recommended approach is to focus on the top 4 priority features for MVP launch, which will provide immediate tangible value to bakery owners and justify the platform subscription costs.
