With the help of Qlo system customers can book rooms by paying some amount or you can say doing advance payment. Now, customers do not have to pay full amount to book rooms in your hotel. They can easily do advance booking and can have confirmed booking status. They will pay the due amount while check in the hotel and admin can update the due amount from backend. Admin can set these partial payment setting from backend. Go to hotel reservation system tab->settings and set the global advance payment settings. Now, you can also enable/disable the advance payment in the particular product. Customer can view the partial payment option while final checkout process. Once the order is placed, admin will go to order and then to the customer order and can update the due amount once paid by customer.
