i wan't to go to the back office an when i click on "paid' to change the status the customer could receive an email "yiu're paiement has just been received"

is it possible ?

Yes, this feature is there. In configuration on the Emails tab, there are two emails at the bottom that must be enabled to be active... a status change email and a PAID status change email. Enable it and customize it to say whatever you want. Then when you mark someone as paid, they will be sent that paid status change email.
