CafeFlow Product Documentation & Technical Manual
The definitive reference for configuring, operating, and scaling CafeFlow across your cafe or restaurant. Covers cloud POS billing, contactless QR ordering, kitchen display workflows, recipe inventory, and thermal hardware integration.
1. System Overview & Architecture
CafeFlow is an integrated cafe and restaurant operating platform built to remove technological friction from hospitality counters. Traditional POS systems lock operators into bulky proprietary terminals and expensive multi-year contracts. CafeFlow runs entirely within modern web standards, executing as a high-performance progressive web app (PWA) on top of Cloudflare's global edge network.
- Browser-Native Execution: Works across Google Chrome, Apple Safari, Microsoft Edge, and Mozilla Firefox on Windows, macOS, iOS, and Android.
- Unified Real-Time Sync: An order placed via guest QR, waiter tablet, or front counter reflects simultaneously on kitchen display screens (KDS) and counter registers.
- Zero Local Server Overhead: Cloud-native distributed database architecture eliminates expensive local POS servers, on-site maintenance contracts, and manual nightly backups.
- Offline Resilience: If internet connectivity drops, cashier registers cache current orders locally and continue driving ESC/POS receipt printing, syncing automatically when connectivity resumes.
2. Cloud POS & Counter Billing
The front-counter register is engineered for high-velocity checkout. Designed specifically for coffee shops, bakeries, quick-service eateries (QSR), and full-service dining rooms, cashiers can enter complex ticket orders in seconds.
Modifier & Variant Groups
Attach flexible item options such as milk alternatives (Oat, Almond, Soy), espresso shot counts, sugar levels, flavor syrups, and kitchen preparation notes without cluttered menu clutter.
Multi-Tender Bill Splitting
Settle tickets across multiple payment tenders: Split an invoice across Cash, UPI QR code, Credit/Debit Cards, and customer store wallet credits in a single transaction.
Floor Plan & Table Matrix
Real-time color-coded table maps show active occupied tables, vacant seating, pending kitchen tickets, and unsettled bills with dynamic timers.
Instant KOT Dispatch
Fire orders instantly to the kitchen display screen or print physical Kitchen Order Tickets (KOT) with automated station separation (e.g. Barista vs Hot Line).
3. Contactless QR Table Ordering & Geolocation Verification
Every table in your cafe can be assigned a durable, high-contrast QR code linking to your cafe's digital ordering portal (e.g., https://app.cafeflow.fun/order/[cafeId]?table=04).
my_locationGeolocation Geofence Fraud Protection
A major security vulnerability of generic QR ordering systems is prank orders placed by individuals outside the venue who snap photos of QR stickers. CafeFlow eliminates this risk through client-side browser geolocation.
• If the device falls outside your configured radius (e.g. 50 meters), the order submission is rejected.
5. Kitchen Display System (KDS) & Station Routing
CafeFlow replaces paper kitchen tickets and loud dot-matrix impact printers with responsive digital touchscreen KDS displays. The KDS runs on standard Android tablets, iPads, or wall-mounted touch monitors.
- Color-Coded Timers: Tickets dynamically change color from Green (<5 mins) to Yellow (5–12 mins) to Urgent Red (>12 mins) to highlight delayed tickets.
- Station Separation: Multi-station routing directs drink items to the espresso bar and food items to the hot line.
- One-Tap Bump Bar: Chefs tap a ticket to mark it ready, instantly notifying the front register and triggering order pickup notifications.
6. Handheld Waiter & Staff App
Floor staff can log in using their secure 4-digit staff PIN on any mobile phone or handheld Android terminal. Waiters take orders directly at the guest's table, modify ingredients, check real-time item availability, and dispatch KOT tickets directly to the kitchen without walking back to the counter register.
7. Recipe & Stock Inventory Control
Track raw ingredient consumption automatically down to the gram, milliliter, or unit.
Recipe Mapping: Link menu items to constituent raw materials (e.g., A Large Cappuccino maps to 18g espresso beans + 240ml whole milk + 1 paper cup + 1 lid).
Automatic Batch Decrementing: When a transaction completes at the counter or via QR, CafeFlow automatically decrements each ingredient from the master stock inventory.
Low-Stock Telemetry: Receive automated threshold alerts when critical items (syrups, cups, beans) dip below your safety stock level.
8. Customer Loyalty & Digital Wallets
Drive customer return frequency without clunky paper punch cards.
Digital Stamp Cards
Automated digital stamps credited to the customer's phone number per visit or qualifying spend.
Scratch & Win Cards
Surprise rewards upon bill payment to gamify repeat visits and delight diners.
Store Credit Wallet
Prepaid customer account balances allowing regular patrons to pay with 1-tap checkout.
9. Thermal Printers & ESC/POS Setup
CafeFlow interfaces directly with industry-standard thermal receipt and KOT printers using standard ESC/POS protocol commands.
- Paper Width: 58mm (2-inch) and 80mm (3-inch) thermal paper rolls.
- Connection Interfaces: USB direct connection, Bluetooth paired printers, or Ethernet / Wi-Fi LAN network printers (TCP/IP port 9100).
- Supported Brands: Epson, TVS, Star Micronics, Posiflex, NGX, Everycom, and generic ESC/POS compliant thermal printers.
- Web Print Bridge: Direct silent printing supported without triggering browser print dialogues on desktop and Android.
