A Catering Item is only applicable to catering orders and is for larger groups of people.
Advance Notice is a feature for Catering Items that allow us to enter how much time is needed to prepare the menu item. You can enter this time as minutes, hours, or days, depending on what the menu says.
Order Minimum is an optional field in the instance when an item has a minimum requirement to place the order. For example, to order a Lunch Box, a diner may be required to order a minimum of 10. That information would go in this box.
Serving Size is where you can put a minimum and maximum for how many diners an item will serve. This information, if appropriate, will be listed on the menu.
