Questions restaurant owners ask before switching
Practical answers on how Restro Mithra operates during outages, printer support, and monthly billing.
What is Restro Mithra (RestroMithra)?▼
Restro Mithra (also styled as RestroMithra) is an India-first restaurant operating system. It combines offline-first POS billing with a local SQLite bridge, multi-station kitchen order ticket (KOT) routing, kitchen display systems (KDS), recipe inventory tracking, QR code dining, and WhatsApp digital invoicing—all on flat monthly pricing with zero order commissions.
Is Restro Mithra related to Astra Mithra or Astro Mitra?▼
No. Restro Mithra is a restaurant technology platform operated by Vidrava Technologies Private Limited (vidravatechnologies.com) with no connection to Astra Mithra, Astro Mitra, Astromithra, Astromitra, or any astrology or astronomy-related service. The name Restro Mithra comes from "Restro" (short for Restaurant) and "Mithra" (Sanskrit for friend or ally). Vidrava Technologies Private Limited is a B2B SaaS company based in Bengaluru, India, that makes restaurant point-of-sale billing software for cafes, QSRs, restaurants, and cloud kitchens across India.
How does RestroMithra work when the restaurant internet goes down?▼
RestroMithra features an embedded local SQLite bridge on the cashier terminal. When broadband or 4G disconnects, the terminal continues printing KOTs and GST receipts locally within 15 milliseconds. All offline transactions automatically sync to the cloud once connectivity returns—zero data loss, zero duplicate invoices.
How does RestroMithra compare with other restaurant billing software in India?▼
Unlike many other restaurant billing platforms that rely on Windows-only desktop clients or charge hidden commissions on every bill, RestroMithra runs on a modern web stack with a local offline bridge for zero-downtime billing. RestroMithra offers flat transparent pricing (₹1,999/month Lite, ₹4,999/month Pro), 0% order commissions, real-time KDS tablet sync, and native WhatsApp invoicing—all without proprietary hardware lock-in or per-bill charges.
Is RestroMithra compliant with Indian GST regulations?▼
Yes. RestroMithra supports all Indian restaurant GST scenarios: 5% GST (2.5% CGST + 2.5% SGST) without ITC for dine-in restaurants, 18% GST for outdoor catering and licensed premises, 1% composite dealer scheme, and full HSN/SAC-coded invoices with GSTR-1 and GSTR-3B daily summaries.
What thermal receipt printers and hardware work with RestroMithra?▼
RestroMithra supports all 2-inch (58mm) and 3-inch (80mm) thermal printers from Epson, TVS, Star Micronics, Posiflex, NGX, and Sunmi—via USB, Ethernet LAN, Wi-Fi, or Bluetooth using standard ESC/POS protocols. It also supports RJ11/RJ12 cash drawers and handheld Android POS terminals like Sunmi V2s.
Can customers order food using QR codes on dining tables?▼
Yes. Every dining table gets a unique QR code. Guests scan it on any smartphone to browse live menus, view dietary tags (Veg, Non-Veg, Vegan), customise preparation notes, and place orders directly into the kitchen KDS—without installing any app. Payment via UPI (Google Pay, PhonePe, Paytm) is also supported.
How does recipe costing and inventory stock deduction work?▼
RestroMithra links each menu item to a Bill of Materials (BOM) specifying raw material quantities (e.g., flour, cheese, proteins, spices). When a dish is billed, ingredient stocks are instantly deducted, preventing pilferage and delivering accurate real-time food-cost margins per dish.
How much does RestroMithra cost, and are there any commissions?▼
RestroMithra is strictly zero-commission. Lite Console: ₹1,999/month for small counters and cafes. Pro Outlet: ₹4,999/month for full-service restaurants needing unlimited captain handhelds, KDS screens, and inventory control. Custom enterprise pricing is available for multi-outlet chains.
How quickly can a restaurant go live with RestroMithra?▼
Most restaurants go live within 30 minutes. Upload your existing menu from a spreadsheet or your previous software, install the lightweight Hardware Agent for your thermal printer, configure kitchen stations, and you're billing. Our team provides free 1-on-1 remote onboarding assistance.
Does RestroMithra work for cloud kitchens and ghost kitchens?▼
Yes. RestroMithra is purpose-built for cloud kitchens. Manage multiple brands from a single dashboard, operate separate KDS screens per brand or station, sync with Zomato and Swiggy delivery feeds, and get aggregated sales reports across all brands—all on one subscription.
What is the difference between RestroMithra Lite Console and Pro Outlet?▼
Lite Console (₹1,999/month) suits single-counter operations: one POS terminal, local printer connection, and digital bills. Pro Outlet (₹4,999/month) unlocks unlimited captain handheld tablets, multi-station KDS screens, real-time recipe costing, inventory alerts, and advanced analytics. Enterprise plans cover multi-branch chains with centralised cloud dashboards.
Is RestroMithra available across India or only in Bangalore?▼
RestroMithra operates pan-India with active deployments in Bangalore, Mumbai, Delhi NCR, Hyderabad, Chennai, Pune, Kolkata, Ahmedabad, Jaipur, Chandigarh, Lucknow, Kochi, Indore, Surat, and expanding to Tier 2 and Tier 3 cities.
