The support is second to none. Every single question is answered quickly with easy to understand explanations. The OwnerRez team have endless patience!
A bit of a learning curve, but once it's up and running it's a great system and easy to add to websites. I love the auto email options.
The main thing I think the software is missing is the ability to use promo codes. Individual quote options for individual properties would be a huge asset as would being able to add personalized options to all forms.
