I need a full-featured Android app (phone and tablet) that lets my small restaurant handle everything from menu edits to final payment, then prints a clean bill in seconds. Menu management comes first: the app must let me create, edit, or disable items in three core categories—Beverages, Main Course, and Desserts—with real-time availability toggles. For the floor staff I want smooth order handling strictly for Dine-in (table-wise KOT routing) and Takeaway tickets. Delivery logic can sit dormant for now but the architecture should make it easy to add later. Billing has to be flawless. Cash, Card, and UPI are non-negotiable payment modes, with GST automatically calculated and shown on the invoice. The moment an order is closed the system should push a KOT to the kitchen and a final bill to a 58 mm or 80 mm POS printer. Daily and monthly sales snapshots, best-selling items, and staff-wise performance must be available in visually clear reports. I also need the customer database to retain contact info and full order history to support loyalty plans down the road. Data lives locally in SQLite for speed; a toggleable cloud sync layer is welcome so I can pull reports off-site. All data must be exportable and protected by secure logins. Deliverables I expect: • Signed APK plus Play Store-ready bundle • Clean, well-commented source code with setup documentation • Basic user guide and one-hour remote onboarding for my team • Up to a year of post-launch support/bug fixes as part of the agreement Integrating a UPI/payment-gateway SDK, configuring the POS printer, and demonstrating the workflow on video similar to the reference clip (https://youtu.be/WEx2vh_sFoY?si=hWA2DZuG41v2VCDS) will form part of the acceptance test. When you send your proposal, break down the development charge, any licence or third-party fees, and what you would bill annually for ongoing maintenance so I can compare options clearly.
