JUCE is released under the Gnu Public Licence, which means it can be freely copied and distributed, and costs nothing to use in open-source applications.
If you'd like to avoid the restrictions of the GPL and use JUCE for a closed-source product, you can purchase a commercial licence. This can either cover a single product or can apply to all products that your company releases.
The commercial license basically lets you use Juce in your product without having to release your own source code, as would be required if you use it under the GPL.
There's no restriction on the number of developer seats, and you get a perpetual license to use any versions of JUCE before version 3.0, or any versions released within a year of your purchase. (As any version 3.0 is probably a long way in the future, that should keep you going for quite a while!)
Buying a license doesn't include any support or extra warrantees about the software.
If that statement worries you, Please have a browse in the forum, where you'll see that in practical terms, Juce's support would beat hands-down most vastly overpriced support packages that other companies offer. If anyone reports a (genuine) bug, my policy is to drop everything and fix it - usually checking-in a fix the same day.
If you're looking for more than just bug-fixing, and would like some expert help in building or designing a Juce application, then I sometimes take on short contracts - please contact me and I'll let you know my rates.
The commercial licenses cost:
