So I activated open tickets to move credit sales off of my ipad and onto my phone to take debit... I did this because we are a drive through business that often has sales that require a signature and fr customer tips (asking a customer if they want to leave a tip is a bit tacky sometimes.) so we save a new ticket... then grab the phone... click tickets.....find the ticket... tap it.... it appears on our phone with the items and the total.... we hit charge.... credit..... then swipe the card..... payment is succsesful..... and we go about our business.... But those paid tickets, if tapped, open right up and you can add stuff to them.... not good since they were already rang out.... then if you it void or cancel the ticket it returns  the payment to the customer.... so how do we close these out and clear them off? do they just clear out at the end of the night? it just amkes me nervous, if an employee jumps in and makes a mistake they could accidentally return all of our debit payments. Any suggestions? Thanks
