1. "Cliente History" with time and amount that was payed
2. For each appointment we have a set time that it takes to do the treatment if the client wants a second appointment afterwards i would like that it automaticly goes to the time. For exampel i have a manicure at 10:30 which takes 45 min the client also wants a pedicure afterwards the appointment should be given at 11:15 i would like that the program calculates this automaticly for me.
3. On the page "Billing System" i would like to have a colum where i can also see the total invoice amount that each client payed that day.
4. The pages "Billing System" and all appointments in the diary I only want visible for the last three months, not further back BUT WHICH SHOULD NOT HAVE ANY INFLUENCE ON THE STATISTIC PROGRAM OR ON THE HISTORY OF THE CLIENTS THAT WE WANT TO KEEP!!
