We try answer and solve all problems of our clients as soon as possible.
There is no any standard for booking form, before buying you could check demo, try free version and ask question on forum or via Presale question from about contact number and also ability to add an address.

Modification of booking form you can do by yourself, we have open source, and you will able make any changes. Also you you can ask us about additional service.
