Purchase Correction

NEW!   We now have our Interactive tool for this section.

Restores the full amount of a previous Purchase, Force Post or Pre-Authorization Completion transaction to the cardholder's card, and removes any record of it from the cardholder's statement.

This transaction is sometimes referred to as "void" or "correction".

This transaction can be used against a Purchase or Completion transaction that occurred same day provided that the batch containing the original transaction remains open. When using the automated closing feature, Batch Close occurs daily between 10 and 11pm Eastern Time.

If the batch has already closed, please refer to Refund.
