Android POS system all in one application front and backend to be in android terminal. I do not want an online system. The system must be 100% functional without a internet connection. Basic functions are product groups, PLU & PLU modifiers table service and takeaway orders. Kitchen printing via local network. Basic end of day reports + back office reports by date range. Please do not bid if you do not have previous examples of your POS work. Very interested in prebuilt project.
