As far as we know this is the only place you can get a website for your holiday letting that has a real-time availability calendar, instant booking and online payments all integrated - no plug ins or 3rd party extras needed. One monthly payment covers everything. After around 10,000 man-hours of development we launched in November 2011, but we didn't stop there. That was just for what we considered the basics - a content management system where you can change ANY of the content, availability calendar and booking system - now we are moving ahead with new features. Some are just minor tweaks and additions to make life easier or add more flexibility, some are going to be quite major, particularly in the key areas for SEO (getting more visitors to your website), converting visitors into paying guests and reporting & management systems.
As we add these features, everybody gets the updates automatically and for free - that is the point of Software As A Service (SaaS) - there is only one codebase - your website keeps getting updated automatically, no need to pay for another website in 3 or 5 years time.
