With Klaus, you only have to pay for the users who are connected to the platform - those who will be reviewing, reviewees (typically agents), and admins. This means that, for example, you can have 132 licenses with your help desk, but only 82 of them connected to Klaus.
We love building new integrations and we usually work quite fast. So do reach out to us to get more info. In the meantime, you can take advantage of our browser extension that allows for reviewing conversations anywhere (without the need to pull data into Klaus).
