I currently run a Windows-based restaurant and bar billing application that handles everyday operations but is showing its age. I need it rebuilt from scratch, preserving every mission-critical function while giving me full ownership of the new source code and database. Core scope My existing system already includes restaurant billing, bar billing, inventory control, KOT printing, and state-wise excise reporting. I also rely on integrated user management, daily sales reports, a searchable customer database, and detailed excise summaries. All of these must carry over exactly as they work today. Deliverables • A Windows desktop application (preferably .NET or similar) that mirrors the current workflow for restaurant and bar billing, inventory, and KOT. • State-wise excise reports generated in the formats required by authorities. • User management module, daily sales reporting, and customer database functionality recreated with equal or better performance. • Well-structured source code, schema scripts, and documentation handed over on each milestone so I have complete ownership at project close. Milestones & hand-off We will break the build into logical milestones—core billing engine, inventory/KOT, excise reporting, and final polish—with payment released upon delivery of working code and documentation for each stage. Experience required Please respond only if you have previously delivered restaurant, bar, or similar POS systems on Windows. Familiarity with KOT flows and excise compliance will be a strong plus; I will ask for a demo or screenshots of past work before we start. If your background matches and you are comfortable providing source and database ownership, let’s discuss timelines and get started.
