Can retailers not process an order if they think the order is invalid?
If you are using UltraShop without the transaction server and gateway, the following applies. When the orders come into the retailer’s mailbox, the retailer views the order and makes a decision whether to process or delete the order. If you are using the transaction server and gateway, the order is passed through the gateway for authorization and the capture and transfer of funds to your merchant account. There is extensive fraud protection built in to the transaction server and gateway.
