Payment at end of month

Payment at end of month

Hello, in Italy usually the payment are at the end of the month. This means that if the invoice is at the 14th of june and the payment is at 30 days, the customer has to pay at 31th of july. Is it possible to have this feature?

Over this, sometimes we have to manage 5 or days more for payment; so its means that if the customer pays at 30 days (end of month) + 10 days, he will pay at 10th of august (with invoice at 14th of june).
Is it possible to have this feature too?
