FAQ Licensing
How is my app pricing determined?
Apps are billed based on the number of users in your Atlassian product. 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.
Note: While this app has features specific to Jira Service Management, the app is technically available across the whole Jira instance. Therefore the above guidelines for licensing across maximum users still apply.
You can find detailed pricing information at Smart Git Integration for Jira product page.
