There are three major types of food delivery software that are used in the industry today. These are:

1) Online ordering systems: These allow customers to order their food online and then pick it up themselves.

2) Mobile apps: These allow customers to order their food from the comfort of their own homes by using an app on their phone.

3) Curbside pickup: This is where customers can order their food online or through a mobile app, but instead of picking it up themselves they call the restaurant to have it delivered to them curbside.
