Designed for Modern Kitchens
Row Level Security (RLS)
Isolated multi-tenancy at the database level. Each restaurant organization only reads and mutates its own scoped relational tables.
WebSocket KOT Dispatch
Instant order sync between waiter tablets and kitchen displays with sub-50ms latency using Supabase Realtime listeners.
Real-Time Inventory Deduction
Atomic PostgreSQL database functions deduct raw ingredient stock upon order billing to eliminate warehouse discrepancies.
Role-Based Access Control
Granular administrative permissions separating waiters, chefs, floor managers, and financial accountants.
Offline Resilience Queue
Local IndexedDB caching ensures POS terminals continue taking orders during internet dropouts and sync cleanly on reconnect.
Dynamic Menu & Modifiers
Real-time updates to menu availability, seasonal pricing, and dish customizations across all POS nodes instantly.
System Design
SaaS Architecture Topology
An elegant, high-throughput distributed layout synchronizing state across nodes with row-level isolated relational storage.
