Tier Amount
This field defines the lower boundary for evaluating the draft amount before determining the amounts for Charge 1 and Charge 2. For example, you might specify 100 in this field. This means that once 100 is reached that Charge 1 and Charge 2 would be applied. You can then set up multiple tier amounts with corresponding Charge 1 and Charge 2 amounts if you wish. If the first tier amount is 100, you might set a second tier amount at 1000 and a third at 5000. The Charge 1 and Charge 2 amounts for tier amount 1000 would be applicable until amount 4999 is reached. At 5000, new Charge 1 and Charge 2 amounts would be applied.
