Restaurant POS System v2 | Offline POS, Inventory & Profit Software

A complete, offline-first restaurant management system — built to replace five separate spreadsheets and a notebook with one screen.

Most restaurant “POS” software is really just a billing till with a menu attached. It tells an owner what was sold, and nothing about what it cost, what’s left in stock, or whether the shift’s cash actually adds up. Restaurant POS v2 was built to close that gap — a single system covering the entire operating cycle of a restaurant, from order to profit.

The Problem

Restaurant owners running two shifts across a day, often without being physically on-site, need real-time visibility — not end-of-week guesswork. They need to know sales as they happen, catch low stock before it stalls an order, reconcile shift cash without a manual count-and-argue routine, and see which menu items are actually profitable versus which are quietly losing money.

The Solution

  • Sales Management — Dine-in, Takeaway & Delivery order entry, automatic bill generation, shift-wise and daily/weekly/monthly sales reports
  • Inventory Management — raw-material and finished-goods stock tracked separately, auto-deducted on every sale via per-item recipes, low-stock alerts, waste/spoilage logging
  • Purchase Management — supplier records, invoice entry that automatically updates stock and ingredient cost, full purchase history
  • Costing & Profit Analysis — recipe-based cost-per-item, live profit margin, daily/monthly Profit & Loss with shift-wise breakdown
  • Shift Management — Day/Night shift start/end built into the login flow itself, opening/closing cash with automatic variance calculation
  • Multi-Branch Ready — every transaction tagged by branch, with a per-device branch selector, ready to scale to a second location
  • Real-Time Remote Dashboard — live sales, inventory and shift status, accessible from any phone, tablet or desktop, anywhere
  • Offline-First — takes and stores orders with zero internet connection, auto-syncs the moment it reconnects
  • Role-Based Access, PDF & Excel Reporting — Admin/Cashier permission levels; every report exports to PDF or Excel

Tech Stack

React · Supabase (PostgreSQL + real-time + auth) · IndexedDB (offline storage) · Progressive Web App (installable, no app-store dependency) · PDF/Excel export via client-side generation.

Result

An owner who’s never on-site can still see today’s sales, catch a stock shortage before it costs an order, close out a shift with confidence the cash is right, and know — not guess — which dishes are actually making money.
