A Flat Tier Type has only one level and is used to create a flat rate discount. This tier type tells the IDI platform how much of a discount (percentage or currency) to apply. You would use this type to create a flat discount of 5% for all the factors that you selected, such as those selected in Usage Types, Service Types, Distance Types, Products, and Locations.
