There are many different types of restaurant ordering system software. Some are used for online orders and some are used for phone orders.

The software is usually in the form of an app or website that can be accessed by customers. The system will take customer's order, calculate the total cost, and provide the customer with a link to pay for their order. This process is done through a set of algorithms that have been created by the developer in collaboration with the restaurant owners.

The software is able to figure out how much meat and vegetables a customer wants in their meal and will then provide them with a list of options that they can choose from. These options are based on what ingredients are available at the time as well as what other customers have ordered before them.
