We have had duplicate charges on our customer's credit/debit cards because Clover asks for payment again after the first payment was processed. However, there is no confirmation that the first payment was processed because the receipt does not automatically print, which is our default set up. We then reprocess the payment since it looks like the first one did not go through successfully.
Also, how can Clover accept payments over the order total? Shouldn't the order be cleared once payment has been made? This should be an automatic feature to avoid problems like this.
This is not the first time we have had payment processing issues with Clover. This is frustrating because our customers think we are trying to get more money from them than we should. And if it goes to chargeback, we have to pay $25 for each incident.
