We build Green Hills for hotels, hotels and more with room reservations. It comes with the best room reservation system. The system allows users to easily view available rooms. In the middle of the booking process, the user can also change the parameter or smoothly select the number using the ajax function, so page refresh is not required! We also create a COUPON message type so that you can create a coupon code for your customers. In the coupon setup, you can set the coupon code, coupon amount, coupon expiration date, type of percentage discount or a specific loan amount.
