I need a lightweight Android point-of-sale app dedicated to my wine shop’s very small catalogue: ten wines (each sold in 750 ml and 350 ml) plus four beers in 330 ml. Everything should happen from a single, modern, sleek screen so my staff can complete a sale in a few taps. Typical flow 1. Tap the wine or beer icon 2. Choose the size (750 ml / 350 ml / 330 ml) 3. Enter quantity 4. Pick payment type (cash or online) 5. Optionally apply a discount 6. Tap “Bill” to generate and print or share the receipt Key points • Clean, modern UI—flat design, sharp typography, no clutter. • One-touch navigation; no deep menus. • Easy back-office panel (even a simple spreadsheet import) to update product names, prices, tax rate and discounts. • Printable or shareable receipt in PDF or thermal-printer format. • Basic daily sales summary on device. • Code written in Java or Kotlin, delivered with full source and build instructions. • Designed so we can switch on extra payment options or employee logins later without a full rewrite. Acceptance I will test on a 10-inch Android tablet: every sale should be possible in under five touches from start to printed bill, and the total must calculate correctly with any discount applied. Please include timeline, tech stack and any similar POS projects you have completed.
