I would like my people to be able to register for an event, pay with a deposit of $X, then recieve an email/txt that reminds them to make a payment of $X on or before a specific date(s). I'd like to be able to set up the amount of each payment and specify how many payments and the date due. I'd like to be able to print a list of current balances that highlight any that are past due. I'd like for the individual to be able to see the history of their payments and the remaining unpaid balance.
