Prepayment or deposit button
Could we get a prepayment or deposit button or option for clients who have already paid a prepayment? I know that you are planning to integrate CC payments but we don't have any option for those that have already paid something yet. Ideally it would show up on checkout so you could add the prepayment of £12.50 to the £30.00 full treatment and it would show you that the remainder to pay is £12.50.
Hope this makes sense!
