Your first option is to call the customer and explain that the charge is greater than the original quote. Ask for the customer’s credit card information and process the sale using the new information.

If you do not want to call the customer, there is a work-around for this issue. Each transaction uses the post-authorization process only once. Each subsequent transaction is processed as a sale to the reserved card. The subsequent sales have no restriction on the amount of the sale. The work-around splits the overly expensivetransaction into two smaller transactions.

If the mail order has 2 or more items on it:

Split the transaction into two smaller transactions.

  1. Enter a ship amount for one of the items.
  2. Process the sale as a post-authorization of the credit card on file.
  3. Re-open the mail order.
  4. Enter the ship amount for the rest of the items.
  5. Process the sale as if it was a post-authorization of the credit card on file.

Although you will follow the same steps, this time the transaction will post as a sale.

If the transaction has a single item on it:

If the transaction has only a single item, create a small transaction and then refund it. This option may not be popular with customers as it generates two charges for the sale of a single item.

  1. Add a small department sale to the mail order and enter a ship amount for it.
  2. Process the sale as a post-authorization of the credit card on file.
  3. Re-open the mail order.
  4. Refund the department sale line and ship the other item.
  5. Process the sale as if it was a post-authorization of the credit card on file.

Although you will follow the same steps, this time the transaction will post as a sale.
