History

It was originally developed on behalf of a prospective client who ran a small hotel in South Wales, but since then it has been extensively modified to work within the Joomla framework to allow users to possess a completely integrated booking solution for their property website.

Although the basic idea revolves around the premise of booking hotel rooms it will happily manage anything that needs to be booked on a per-day basis. This includes holiday homes and apartments, boats, cars, pitches in a camp site etc.
