How Incremental Authorization Works

In credit card transaction processing, you can see two kinds of authorizations – original authorization and incremental authorization.

Incremental Authorization Example.

The purpose of the incremental authorization is to increase the previously authorized amount.

And merchants link the additional (incremental) authorization to the original (first) authorization and send for settlement to ensure proper liability coverage.

Incremental Reversal Transaction.

Reversal management is also unique to these transactions. Merchants should contact their acquirer for specifics on the data requirements for these transactions. Guaranteed Reservations It is common for cardholders to reserve services in these merchant categories well in advance of the date of use.

While there is no standard approach, there are common practices that have evolved for each specific merchant category.

Examples for Incremental Authorizations.

Vehicle Rental – An account status inquiry is completed at the time of the request to confirm the cardholder account is in good standing. An authorization is submitted for the agreed-upon amount at the initiation of the vehicle rental.

Cruise Lines – Typically, cruise lines charge the entire amount of the cruise at the time of the reservation. Any charges incurred during the cruise are managed as separate transactions, using the incremental authorization process if multiple purchases are to be aggregated into a single settlement record.

Lodging Reservations – Lodging merchants participating in the Guaranteed Reservations service have the option of utilizing the rules in regards to the “no show” policies.

The Cardholder is obligated to cancel a confirmed reservation before 18:00 at the hotel, motel, or resort (Merchant’s local time). If the cardholder fails to cancel the confirmed reservation, the Merchant can charge the Cardholder a no-show charge equal to one night’s lodging.

In this case, it is appropriate for the merchant to send an authorization for the amount that would be charged for one night’s lodging if they so choose.
