LTS RELEASE 4.8

1. The Dual-Engine Hybrid Architecture

The fundamental flaw in traditional POS software is reliance on either a fragile local desktop database or a 100% cloud connection that halts whenever internet fluctuates. RestoAppX pioneers the True Dual-Engine Architecture: combining local client-side IndexedDB speed with cloud background replication.

Engine A: Local Client Database (IndexedDB)

Every terminal maintains an active, fully indexed local database inside the browser or native runtime environment.

0.00ms Network Latency: Invoices, menu lookups, and KOT generation execute purely in-memory on the device.
Full Offline Autonomy: Internet outages of 5 minutes or 5 days will never stop your cash counter from billing.
Local Hardware Printing: ESC/POS thermal printers print instantly via USB, LAN, or Bluetooth without cloud hops.

Engine B: Bi-Directional Delta Cloud Sync

An intelligent background sync worker monitors network availability and securely batches transactions to the cloud.

Automatic Delta Queue: Offline transactions are cryptographically sequenced with local UUIDs.
Conflict-Free Replication: Built-in resolution logic prevents duplicate bill numbering or stock over-deductions.
Live Management Sync: Owners receive live updates on mobile dashboards the second connectivity resumes.

6. Smart Recipe Management & Raw Material Depletion

Food cost control makes or breaks restaurant profitability. RestoAppX features an industrial Bill of Materials (BOM) engine that links every menu dish to its raw ingredients and automatically depletes inventory in real-time as bills are settled.

Bill of Materials (BOM) Recipe Formulation

Specify exact raw material consumption for each dish and portion variant:

Example BOM: Paneer Butter Masala (Full Portion)

• Fresh Paneer: 200 grams

• Amul Butter: 30 grams

• Cooking Cream: 25 ml

• Makhani Gravy Base: 180 ml

• Cashew Paste: 15 grams

• Garam Masala & Spices: 10 grams

✓ When 1 order of Paneer Butter Masala is billed, all 6 ingredients deduct instantaneously from store stock!

Complete Store & Procurement Lifecycle

Minimum Threshold Alerts: System alerts store manager when Paneer drops below 5kg or Cooking Oil drops below 10L.
Purchase Orders (PO) & GRN: Generate vendor POs and verify deliveries against Goods Received Notes with invoice price logging.
Supplier Master Ledger: Track payment histories, vendor outstanding balances, and credit terms in one dashboard.
Wastage & Spoilage Logging: Separate accounting for prep waste, burned food, returned dishes, and staff meals.

Inventory Control & Cost Control Features

Module Feature	Technical Specification	Business Outcome
Multi-Location Stores	Main Central Store + Kitchen Prep Store + Bar Dispense Store with internal transfer slips	Pinpoints pilferage to exact location
Live Food Cost %	Dynamic calculation of Recipe Cost vs Selling Price (Real-time Menu Margin)	Eliminates loss-making menu items
Physical Stock Variance	Weekly physical stock audit compared against theoretical system consumption	Catches raw material theft immediately
Batch & Expiry Control	FIFO (First-In, First-Out) tracking for perishables (dairy, meats, seafood)	Prevents spoilage and health code violations
Sub-Recipe Nesting	Master gravies, sauces, and dough batches mapped as ingredients for final curries	Accurate prep-station accounting
