The amount that the customer will be charged.
This field contains the final settlement amount of the transaction. In most cases, this is the TransactionAmount from the original authorization request. However, you may settle a lesser amount (ie: Partial shipment or backordered stock). If using the Restaurant IndustryType, you may also increase the SettlementAmount by adding any TipAmount (if present).
Note: The decimal point is required to be specified within the amount.
