delivery application multiple restaurants

delivery application multiple restaurants android and ios + control panel I want a multi-restaurants food ordering app, for the customer to order from inside the restaurant to the table that he is sitting. Android and IOS When opening the app, the client will click “Scan QR Code”. This QR code is generated by the restaurant itself (through its control panel). The QR code will automatically recognize which that restaurant is the QR code and will open a table for the customer, showing the menu of that restaurant. The menu will always be logged on the customer's mobile phone while he is in the restaurant. The customer will choose the dishes, dish size, add or remove ingredients, and you can add extra ingredients. The customer can place multiple orders, and these orders will being noted in the client application at their desk When finished eating, the customer clicks on “End Order” The customer will choose whether to pay the bill through the app itself or whether to pay at their desk (by choosing the "Pay at Desk" option) After paying the bill, or clicking "Pay at Table", the menu is closed from the customer's mobile and the table is closed, giving the option to evaluate how your visit was in the restaurant, rating from 1 to 5 stars and may make a comment. I need you to have the option to call the waiter at the table The payment method within the app will be PagSeguro (Brazil) Need an login on app to manage the tables: When a customer scans the QR code and opens a table, the app will issue an authorization to accept or not that person at that table, through the account that is logged in that restaurant The App needs two control panels, one general to control everything, and one for each restaurant owner to run their restaurant. On the restaurant owner's panel: -It must be possible to add and change menu items. - Add or remove tables -It will be showing orders that were placed at that table and other tables as well. When the customer pays or clicks "Pay at Table" that choice will appear on the panel at their respective table. When this message appears, the 'Close Table' option will appear. When you click to close the table, orders from that table are archived and the table is reset to new orders. In the general panel: -You must have the option to register new restaurants by giving a restaurant login and password to access your own control panel -Must have option to close registered restaurants
