The first phase was to conduct online research. I searched for tutorials and walk-through videos from competitors such as Lightspeed, Oracle, Square, and Elo Touch. As requested by the client, I had to create split-screen prototypes. The left side is used as a food runner, but becomes a receipt panel when the cashier begins to take orders. The right side allows the cashier to search menus and categories and add items to carts.
Then, I created several sketches, wireframes, and designs for different POS features, such as menu management, checkout screens, and payment methods.
