Cloud apps are sold as a monthly or annual subscription. You are eligible for support and automatic version updates as long as your subscription is active. When your subscription renews each month, you are automatically billed for apps based on the number of users in your instance. To figure out the exact cost, click here and enter the number of users you have.
If app pricing changes after your initial purchase, there's a 60-day grandfathering period during which you can renew based on the old pricing.
Apps are billed based on the number of users in your Atlassian product. Jira Cloud apps are priced based on the maximum number of users of the Jira products on your instance. For example, if you have Jira Software (50 users) and Jira Service Management (10 agents) in the same instance, you pay the 50-user price for apps.
Note: While this app has features specific to Jira Service Management and Jira Software, the app is technically available across the whole Jira instance. Therefore, the above guidelines for licensing across maximum number of users still apply.
