I have some questions:

we bought the Invoice module for booking, but it does not work with Jommla 3.0. How is it possible to make it compatible with Joomla 3.0 to run?

German translations are incomplete for Joomla 3.0. We have translated very much himself.

If the customer selected a calendar in 2 days, 2 nights will be charged. But should usually only one night will be charged. Is it possible to configure it?

Is a better design of bookings calendar for planned?

What's new in Artio Booking 2.7 compared to 2.5?

Can the Book it button to another place where and how?
