For email confirmations, to show 'Left to pay from $xx'. Even though the booking process, price shows 'from $xx', however, the email confirmation shows the remaining to be paid without stating that it is 'from $xx' and a few times, my clients have complained that the email says they only have to be the remaining amount. For eg:

when booking online, the service 'Wrinkle reduction: from $130'. Deposit paid is $50. Email shows 'Left to pay: $80', instead of ':from $80'.
