I need a mobile app that can create and print two identical copies of every bill—one for the customer and one for the driver—using a TVS thermal printer. Each bill will carry our company logo and a system-generated, unique barcode. When that barcode is scanned with any standard phone camera or scanner, the duplicate copy of the bill must open immediately on the user’s device. The workflow is simple: fewer than twelve fields are filled in for each transaction, the app saves the data, produces the two printouts, and stores a cloud-accessible version linked to the barcode. A straightforward username-and-password login keeps everything secure. Key points the finished solution must cover: • Seamless Bluetooth or USB communication with the TVS thermal printer (other brands in future should be easy to add). • Fast barcode generation and a landing page that displays the stored bill on mobile browsers. • Clean, minimal entry form with <12 inputs and our logo positioned correctly on the printout. • Source code, build files, and basic setup documentation so we can point our own domain to the hosted bills. If these pieces work smoothly together, the project is complete.
