SettlementAmount Property

The amount that the customer will be charged.


public string SettlementAmount { get; set; }
Public Property SettlementAmount As String

Default Value



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). This field must always be greater than zero.

Note: If a transaction includes a GratuityAmount amount, the SettlementAmount must reflect the total of the original authorized amount plus the GratuityAmount (this is only applicable to the itResturant IndustryType).

This must be formatted as a dollar amount with a real decimal point, excluding the dollar sign. For instance "12.00".

Notes for the Hotel IndustryType:

To obtain the best interchange rate for Visa transactions in the Hotel IndustryType, the check out amount (SettlementAmount) must be within 15% of the original authorization amount. If the SettlementAmount is less than the original authorized amount by more than 15%, you must perform an authorization reversal using the PTechReversal component. This will immediately release funds from the cardholder's open to buy amount. The original transaction must then be settled for the new amount as usual. However, if the SettlementAmount exceeds the original authorized amount by more than 15%, you must submit an incremental authorization to make up the remaining amount. In this case even though there are two separate transactions, they are tied together with the same authorization code. Therefore, only the original authorization (with the newly updated SettlementAmount) is to be sent in the settlement.

Non-Visa transactions do not allow for Incrementals to tie transactions together, nor Reversals to release funds from the cardholder's open to buy amount. There are no restrictions on the difference between the SettlementAmount and the original authorization amount. However, if the merchant suspects that the final transaction amount will be substantially higher than the original authorization amount, the merchant should perform an additional authorization for the difference. This subsequent authorization must be sent to the host as a standard authorization-only transaction, and will not be tied in any way to the original transaction. Both transactions must be present in the settlement.


Notes for the Restaurant IndustryType:

For Visa transactions, to obtain the best interchange rate the SettlementAmount must be within 20% of the authorized amount. The initial authorization must be submitted for the actual transaction amount. It must not be altered to include an additional percentage that accounts for a tip being added before settlement.

The same rule applies to MasterCard transactions, with the exception that MasterCard allows the SettlementAmount to be within 25% of the authorized amount.

There are no rules concerning authorization and settlement amounts for other card types.
