🧠 1. APPLICATION OVERVIEW ✅ Purpose A centralized, real-time restaurant management system that streamlines: Order processing (POS + online) Inventory tracking Staff coordination Reservations Analytics & reporting 👥 Target Users & Personas Restaurant Owner Needs insights, reports, cost control Manager Oversees staff, inventory, daily ops Cashier Handles POS orders Kitchen Staff Tracks and prepares orders Waiter Manages tables and orders Admin System configuration ❗ Core Problems Solved Disconnected systems (POS, inventory, reservations) Manual stock tracking → errors Poor kitchen communication Lack of real-time visibility Inefficient staff coordination 🚀 Unique Value Proposition Real-time sync via WebSockets (Pusher) Fully integrated modules (POS + Inventory + Staff) Mobile-first responsive design Live kitchen tracking + alerts Data-driven decision making ⚙️ 2. FEATURE BREAKDOWN 🔹 Core Features (Must-Have) 🧾 POS Module Order creation (dine-in, takeaway) Split bills Payment processing (cash, QR, card) Receipt printing 🍽️ Table Management Table layout visualization Reservation system Table status (available, occupied, reserved) 👨‍🍳 Kitchen Display System (KDS) Real-time order feed Status updates (pending → cooking → ready) Priority tagging 📦 Inventory Management Stock tracking Auto deduction on order Low-stock alerts 👥 Staff Management Roles & permissions Shift scheduling Activity logs 📊 Analytics Dashboard Sales reports Popular menu items Staff performance 🔸 Advanced Features (Scalable) AI demand forecasting Multi-branch support Supplier management Loyalty system QR menu ordering Offline mode sync Voice order input (future AI) 🧩 Modules Auth & User Management POS & Orders Tables & Reservations Kitchen System Inventory Staff Reports & Analytics Notifications (real-time) 🔄 3. USER FLOW (STEP-BY-STEP) 🟢 Onboarding Admin registers restaurant Setup: Menu items Tables Staff accounts System ready 🟡 Daily Operation Flow A. Order Creation (Cashier/Waiter) Select table or takeaway Add menu items Submit order → triggers: Kitchen display Inventory deduction B. Kitchen Flow Order appears (real-time) Staff updates status: Pending → Cooking → Ready Waiter notified C. Payment Flow Cashier opens order Select payment method Generate receipt Close order D. Inventory Flow Stock auto-reduced If below threshold → alert triggered E. Reservation Flow Customer reserves table System blocks slot Waiter prepares table 🔴 Edge Cases Out-of-stock → prevent ordering Network failure → fallback queue Payment failure → retry flow Order modification → sync updates 🔀 4. SYSTEM FLOWCHART (TEXT DIAGRAM) [User Login] ↓ [Dashboard] ↓ [Create Order] → [Select Table?] → Yes → Assign Table ↓ No [Takeaway Order] ↓ [Submit Order] ↓ [API: POST /orders] ↓ [Broadcast via Pusher] ↓ [Kitchen Receives Order] ↓ [Update Status] ↓ [API: PATCH /orders/{id}] ↓ [Notify Waiter] ↓ [Payment Process] ↓ [Update Inventory] ↓ [Generate Report Data] 🗄️ 5. DATABASE DESIGN 🔹 Core Tables users id (PK) name (VARCHAR) email (UNIQUE) password role_id (FK) created_at roles id name (admin, cashier, etc.) menu_items id name price category_id stock_quantity is_available orders id table_id (nullable) user_id status (pending, cooking, ready, paid) total_price created_at order_items id order_id menu_item_id quantity price tables id name status capacity reservations id table_id customer_name time_start time_end inventory_logs id menu_item_id change_type (in/out) quantity timestamp staff_shifts id user_id shift_start shift_end 🔗 Relationships users → roles (N:1) orders → users (N:1) orders → order_items (1:N) menu_items → order_items (1:N) tables → orders (1:N) tables → reservations (1:N) ⚡ Indexing orders.status menu_items.name reservations.time_start users.email (unique) 🔌 6. API DESIGN 🔐 Auth POST /api/auth/login POST /api/auth/register GET /api/user 🧾 Orders GET /api/orders POST /api/orders PATCH /api/orders/{id} DELETE /api/orders/{id} Example Request POST /api/orders { "table_id": 1, "items": [ { "menu_item_id": 2, "quantity": 2 } ] } 📦 Inventory GET /api/inventory PATCH /api/inventory/{id} 📊 Reports GET /api/reports/sales GET /api/reports/top-items 🔐 Auth Flow Laravel Sanctum / JWT Token-based authentication Role-based access middleware 🏗️ 7. TECH ARCHITECTURE 🖥️ Frontend (Vue.js) Vue 3 + Composition API Vue Router Pinia (state management) Axios (API) Pusher JS Structure: /components /pages /store /services /layouts ⚙️ Backend (Laravel) MVC architecture REST API Laravel Events + Broadcasting (Pusher) Queues (Redis optional) 🗄️ Database MySQL (normalized schema) Use migrations + seeders 🔗 Integrations Pusher → real-time updates Payment gateway (Midtrans / Stripe) Docker for containerization 🎨 8. UI/UX STRUCTURE 🧭 Page Hierarchy Login Dashboard POS Screen Kitchen Display Inventory Staff Management Reports 🧩 Components Order Card Table Grid Inventory Alert Badge Real-time Notification Toast Charts (sales) 🎯 Design Principles Light theme (white + soft blue) High readability Minimal clicks (≤3 per action) Real-time widgets (live updates) Mobile responsive (tablet-first for POS) 🔐 9. SECURITY & PERFORMANCE 🔒 Security HTTPS (SSL) JWT/Sanctum auth Role-based access control Input validation (Laravel FormRequest) SQL injection protection (Eloquent ORM) ⚡ Performance API caching (Redis) Lazy loading components WebSocket instead of polling DB indexing CDN for assets 🚀 10. DEPLOYMENT PLAN ☁️ Hosting DigitalOcean Droplets Docker containers: app db nginx 🔄 CI/CD GitHub Actions: Build Docker image Run tests Deploy to server ⚙️ Environment .env configs: DB credentials Pusher keys API keys 📈 11. FUTURE SCALABILITY 🔮 Feature Expansion Multi-branch system Franchise management AI analytics (predict demand) Customer mobile app 📊 Scaling Strategy Horizontal scaling (load balancer) Microservices split: Orders service Inventory service Queue workers for async tasks Read replicas for DB ✅ FINAL NOTE This blueprint is: Fully modular Real-time ready Production-scalable Directly implementable in Vibe Coding workflows If you want, I can convert this into: ✅ Database migration files (Laravel) ✅ Starter repo structure ✅ UI wireframes ✅ Full API implementation code Just tell me 👍
