1. Did the IPB licence price go down (from 175$ fo 165$) or am I seeing this as a person who already owns 1 licence (discount perhaps)?

2. Right now, my IP.Chat licence is valid for 6 months (free 5 users plan) as is my current licence. If I upgrade to 20 users a year (20 dollars) it will last, as presumed a whole year, even after my active licence expires (board and apps)?

Thanks in advance & keep up the good work! :)

Yes you get discounts for multiple licenses :)

The system will automatically adjust the price you pay and such to account for the upgrade and the time difference.
