Need booking popup before checkout

Bro, In Maintenance (Entretien) part, when I am planning the Maintenance after the calendar scheduling, when I am clicking on "Ajouter au Panier" and then there is a pop up withe order details and I need to proceed to payment. BUT!!! We don't need to proceed to payment there must be a active button ORDER. Once I am clicking on Order, the System must land me to my orders and there I need to see the order in ly order's list. So, the bank credentials request must be removed and on its place me as a customer I need to see the orders list.
