Write a PMS (Property Management System), Initially for my motel using HTML5 and a background database. After we have tested it I want to market it to other hotels, motels worldwide. The PMS needs to interface (exchange information) with online marketing sites such as wotif.com, booking.com, expedia.com, agoda.com etc. The hotel owner needs to login and see a visual representation of the available rooms he has on his property for letting, the rooms that have been let, and the ability to make changes. All this has to be done online. The online software has to be able to generate income and occupancy reports for the property. The software needs to be able to securely store credit card information of the guests. The software needs to be able to dynamically adjust prices according to a formula I will develop.
