I see you need an Android billing app tailored for a quick-service restaurant with inventory management, sales reporting, and dual user roles, plus seamless kitchen order ticket printing. Your focus on a lightweight, reliable app that works offline and syncs later is clear and important. Your requirement for automatic KOT ticket printing directly from the app to a receipt printer, without extra steps for staff, stands out. Also, having a detailed setup guide and user manuals for both cashier and manager roles shows you want a complete, user-friendly solution. I’ve built Android apps with offline-first architecture that manage inventory and handle billing smoothly, integrating directly with Bluetooth receipt printers for instant KOT printing. I delivered APKs with full source code and documentation, ensuring easy installation and setup, which aligns well with your deliverables. I can complete this project within 3 weeks, providing you with the APK, source code, setup guide, and manuals. Let’s discuss your printer model and any other specifics to get started.

@ajittkumark

Hi i have 6+ years of experinece in C#. This fits well as an Android first billing system because restaurant flow depends more on speed and reliability than on heavy interface complexity. The important part is keeping billing, inventory deduction, and KOT printing tightly linked so staff can complete an order in one smooth step without duplicate actions. My approach: • Build the app in .NET MAUI or native Android depending on preferred long term maintenance • Keep billing flow optimized for quick item selection and instant order confirmation • Separate cashier and manager permissions clearly • Deduct inventory immediately after confirmed billing • Generate KOT automatically for kitchen printing Core modules: • Product and inventory management • Billing with item wise order handling • Role based login for cashier and manager • Sales reports by day, item, and period • KOT printer integration through Bluetooth or USB compatible receipt printer Technical details: • C# with .NET for maintainable shared logic • SQLite for local offline storage • Sync ready structure if online reporting is added later • Printer communication layer for standard thermal printers Important implementation detail: KOT printing should happen as a dedicated print queue step so failed printer communication does not block billing completion. Deliverables will include APK, source code, setup guide, printer pairing steps, and short user documentation. Looking forward to work in this project.

@tejbirbhatia

Hi there! I noticed your need for a lightweight Android billing application tailored for a quick-service restaurant with a focus on inventory management, sales reporting, and smooth billing flow for different user roles. The automatic generation of printed KOT tickets is crucial, so seamless integration with a compatible receipt printer is a key feature. An offline-first approach with the ability to sync data when a connection is available is also a priority. In a similar project, I developed a custom billing app for a cafe that required real-time inventory tracking and user-friendly interface for staff. The app streamlined the billing process and improved efficiency in managing orders and inventory. I have a question regarding the specific models of receipt printers you plan to use for the KOT printouts. Could you please provide more information on this? Looking forward to the opportunity to discuss this project further. Thanks, Tejbir Bhatia
