From what we know, people log meeting times to issues like “team meetings” and “daily stand-ups”, or if the meeting is around some particular occasion, it has its issue in Jira.
So, to calculate meeting costs, you need to do the following steps:
Install Cost Tracker add-on
Set rates for people
Set team permissions in order not to share the sensitive information
Go to the issue where people log their meeting time and activate “Cost Tracker”.
