Mobile Hybrid Restaurant

I want to create a hybrid-based mobile restaurant project. so it can be used on android and iOS even computers. In general the application is in the form of: 1. Customer download the application then signup and enter the main menu. 2. The main menu contains many tennants in the foodcourt 3. Then the customer selects one or more of each tennant to order food. 4. Then from the order will go to the cashier, as proof of payment. and go into each tennant to prepare the order of food that has been entered. 5. Payment system is only done using mobile and cash. The mobile payment gateway reference is at [login to view URL] And of course cash payment. 6. Cashier will receive receipt of payment and print to be given to customer. 7. The payment system is already incorporated into the tax. So there is no additional tax, because the price includes tax. 8. Tennant is granted access to edit, update, and delete the food content to keep it updated. And automatically will go into the cashier system. 9. The database used is firebase.
