License for subset of users?
What if only a few users need Risk Register?
You want to purchase Risk Register for Jira, but only a small subset of users intend to use it; can you license the product just for the small subset of users?
The Atlassian Marketplace licensing framework
Licenses for Risk Register are purchased via the Atlassian Marketplace, and are subject to the rules established by that Marketplace. As vendor of the product, ProjectBalm has no control over the purchase process, nor the scope of the license that you purchase.
How is the license volume determined?
For Jira, you must purchase the app license that matches the highest Jira application tier. For example, if you have a 500-User Jira Software license, and a 20-Agent Jira Service Management license, your Jira apps must be at the 500-User level. – "Which license do I choose when purchasing an app?"
Atlassian has a post about it here: Licensing add-ons: Can I purchase an add-on for only subset of my users?
