Unfortunately, it is very very restricted with the non-commercial version. It is certainly not for a novice. Lots of careful reading is required to get this up and running properly. It won't work with a localhost as it requires a website already up and running to connect to it. There are monthly or yearly payment required for the Professional version. The non-commercial version doesn't allow you to set up a schedule whereas according to the documentation mentioned above that you can add a schedule - this is not true and I couldn't even amend the default schedule! Very difficult to test properly! I had high hopes to be able to use this online booking but am now sceptical as thought this would be good for a client to use but it's unlikely I'll recommend this one as it isn't user friendly!
I'm disappointed that you feel you weren't able to get a true feel for our product. I'd be more than happy to assist you with the set up so that you can try Bookings in full.
Our free version does in fact allow for you to set up a schedule. A schedule is necessary in order to allow your customers to choose from your available resources/products. Again, if you feel our documentation does not clearly explain this then I can have someone from Zingiri either call or email you.
