In your mobile you enter the articles with their name group and price only once.They call you from a table. In the App Bar you are already seeing if it is pending to collect, to serve, to write orders etc.If you have to enter order, it works like your notebook but without having to write or remember prices simply by selecting articles.If an item is missing, simply add it to "Edit Menu" and it is ready for the next orders.Just like in your ideal notebook, in the sheet of each table you will see each article with its price and the total. Also if the table is pending to serve or charge.The requests or changes of status that you write down in your terminal will appear synchronized in the terminals of your connected colleagues. Likewise theirs in your terminal.
