There are many types of food delivery software that exist. Some are for restaurants and some are for the customers. For restaurants: - They have to install a system which is able to accept orders. - They can also integrate with other third party systems like POS, inventory management, and other back office systems. - Most of them offer loyalty programs and customer analytics as well. For customers: - Customers can order their food online or through an app on their phone or computer. - The customer's information is saved in the company's database so they don't have to enter it again when they order next time.
