🎯 Product Vision

• For: Cafe owners, Tea shops, and small-to-medium F&B chains.
• Who: Are seeking a comprehensive synchronized solution: Ensuring maximum operational efficiency at the Point of Sale (POS), while providing an in-depth management system for cash flow, Cost of Goods Sold (COGS), and staff productivity in real-time.
• OmniPos is: A unified F&B management platform.
• That: Optimizes sales workflows (Ordering/Payment) and automates complex managerial accounting tasks.

🚀 Key Features

1. Smart POS Operations

• Optimized Service Speed: Streamlined touch interface designed to handle peak hour traffic, allowing cashiers to complete orders in seconds with minimal taps.
• Real-time Floor Management: A dynamic dashboard providing instant visibility of table occupancy and order fulfillment status (Waiting/Served), ensuring seamless staff coordination without manual checks.

2. Inventory & Recipe Engine

• Precise Cost Control: Advanced Bill of Materials (BOM) management allows defining complex recipes (e.g., 1 Coffee = 20g Beans + 30ml Milk), enabling accurate Cost of Goods Sold (COGS) tracking.
• Automated Stock Deduction: Inventory is automatically calculated and deducted immediately upon transaction completion, maintaining strict consistency between Cash Flow and Physical Stock.

3. Security & Staff Efficiency

• Seamless Access: Rapid passwordless login via QR Code scanning on the POS device, integrated with automated time-attendance tracking.
• Strict Access Control: Comprehensive Role-Based Access Control (RBAC) ensures sensitive data (like Purchase Prices) is visible only to authorized personnel (Admin), preventing internal data leaks.
