Multi-Tenant Restaurant SaaS
A scalable multi-tenant SaaS platform focused on staff-side operations rather than customer websites. Enables restaurants to manage QR-based table ordering, table-claim and handoff flows between waiters, and real-time order tracking across multiple locations, all with isolated tenant data. Designed as a lightweight, staff-first tool with basic QR menus (no public website layer) for fast adoption in busy dining environments.
Problem
Restaurant owners and SaaS providers faced challenges building scalable multi-tenant systems with proper data isolation, managing waiter-table assignments, tracking orders across multiple locations, and coordinating staff handoffs during shift changes, while traditional paper menus were costly to update and environmentally unfriendly.
- Need for complete data isolation between different restaurant tenants in a shared infrastructure
- Manual table assignment and waiter coordination led to service gaps during shift changes
- Lack of table claiming system caused confusion about table ownership and responsibility
- Manual order tracking led to errors and delayed service
- Inefficient event booking process caused scheduling conflicts
- High recurring costs for printing updated menus
- Lack of real-time analytics made service optimization difficult
Solution
A full-stack multi-tenant SaaS platform with Django backend and Next.js frontend featuring complete tenant isolation, waiter table claiming workflow, real-time order tracking, QR-based digital menus, event booking system, and comprehensive analytics with role-based access control.
- Implemented multi-tenant architecture with row-level security and complete data isolation per restaurant
- Built waiter table claiming system allowing staff to claim tables, manage orders, and transfer ownership to other waiters
- Developed real-time order management dashboard with Pusher for instant updates across all staff devices
- Created QR code generation system linked to table-specific ordering with tenant-aware routing
- Implemented calendar-based event booking system with conflict detection per tenant
- Built comprehensive analytics dashboard with tenant-scoped data for sales, inventory, and staff performance
- Designed role-based access control system for restaurant owners, managers, and waiters
Outcome
The multi-tenant platform successfully onboarded multiple restaurants with complete data isolation, streamlined waiter workflows with table claiming, reduced order processing time, increased event bookings, and improved customer satisfaction. The digital menu system eliminated printing costs and enabled instant updates.
- Successfully deployed multi-tenant architecture serving multiple independent restaurants
- Eliminated table assignment confusion with waiter claiming and transfer system
- Seamless shift handoffs with table transfer functionality between waiters
- Substantial reduction in order processing times with real-time updates
- Increased event bookings and associated revenue
- Eliminated menu printing and update costs
- Improved customer satisfaction ratings across all tenant restaurants
- Centralized restaurant ordering into a single QR-based system with real-time order flow from table to kitchen
Challenges
Implementing multi-tenant data isolation, real-time table claiming synchronization, and ensuring optimal performance across various devices while maintaining security boundaries required careful architecture planning.
- Designing row-level security and complete data isolation between restaurant tenants
- Implementing real-time table claiming with conflict resolution when multiple waiters claim same table
- Building secure table transfer workflow with proper authorization and audit trails
- Ensuring database consistency with high-volume concurrent transactions across multiple tenants
- Optimizing real-time updates for table status changes across all connected devices
- Designing intuitive interfaces for waiter table management and customer-facing ordering
